The non-fluent/agrammatic variant of primary progressive aphasia (nfvPPA) is a neurodegenerative syndrome primarily defined by the presence of apraxia of speech (AoS) and/or expressive agrammatism. In addition, many patients exhibit dysarthria and/or receptive agrammatism. This leads to substantial phenotypic variation within the speech-language domain across individuals and time, in terms of both the specific combination of symptoms as well as their severity. How to resolve such phenotypic heterogeneity in nfvPPA is a matter of debate. 'Splitting' views propose separate clinical entities: 'primary progressive apraxia of speech' when AoS occurs in the absence of expressive agrammatism, 'progressive agrammatic aphasia' (PAA) in the opposite case, and 'AOS + PAA' when mixed motor speech and language symptoms are clearly present. While therapeutic interventions typically vary depending on the predominant symptom (e.g. AoS versus expressive agrammatism), the existence of behavioural, anatomical and pathological overlap across these phenotypes argues against drawing such clear-cut boundaries. In the current study, we contribute to this debate by mapping behaviour to brain in a large, prospective cohort of well characterized patients with nfvPPA (n = 104). We sought to advance scientific understanding of nfvPPA and the neural basis of speech-language by uncovering where in the brain the degree of MRI-based atrophy is associated with inter-patient variability in the presence and severity of AoS, dysarthria, expressive agrammatism or receptive agrammatism. Our cross-sectional examination of brain-behaviour relationships revealed three main observations. First, we found that the neural correlates of AoS and expressive agrammatism in nfvPPA lie side by side in the left posterior inferior frontal lobe, explaining their behavioural dissociation/association in previous reports. Second, we identified a 'left-right' and 'ventral-dorsal' neuroanatomical distinction between AoS versus dysarthria, highlighting (i) that dysarthria, but not AoS, is significantly influenced by tissue loss in right-hemisphere motor-speech regions; and (ii) that, within the left hemisphere, dysarthria and AoS map onto dorsally versus ventrally located motor-speech regions, respectively. Third, we confirmed that, within the large-scale grammar network, left frontal tissue loss is preferentially involved in expressive agrammatism and left temporal tissue loss in receptive agrammatism. Our findings thus contribute to define the function and location of the epicentres within the large-scale neural networks vulnerable to neurodegenerative changes in nfvPPA. We propose that nfvPPA be redefined as an umbrella term subsuming a spectrum of speech and/or language phenotypes that are closely linked by the underlying neuroanatomy and neuropathology.

This study investigated the processing of double negation in Chinese children with reading difficulties. The comprehension of Mandarin affirmative, single negative and double negative sentences was tested with Chinese young poor readers and typical readers, using a sentence-picture verification task. Results showed that double negative sentences were most difficult to process for both groups; the poor readers performed significantly worse than the typical readers in comprehending double negative sentences, while no difference between the two groups was observed in comprehending affirmative and single negative sentences. Besides, morphological awareness correlated with the comprehension of double negative and single negative sentences in poor readers, while this correlation did not emerge with typical readers. Overall, our results suggest that children with reading difficulties experienced great processing difficulty in double negation, confirming that reading disorders are also characterised by oral language difficulties, in particular in the comprehension of sentences requiring high processing costs.

This study aimed to identify the comprehension strategies employed for active, passive, and causative sentences and the involvement of phonological memory, which is a subsystem of working memory, in the comprehension skills of Japanese-speaking children with intellectual disability (ID) compared to those with typical development (TD). The participants were 29 children with ID and 18 children with TD who were matched according to mental and vocabulary ages and phonological memory scores. A picture selection method was employed as a sentence comprehension task. The stimulus sentences were grouped into four patterns of word order: subject (S) – object (O) – verb (V), OSV, SV, and OV. For example, in active sentences, the subject and object are assigned to agent and patient, respectively. The results indicated that children in both groups made comprehension errors for sentences that lacked information regarding the agent and sentences in which the two-noun sequence inverts the typical agent – patient or instructor – instructed order. Phonological memory's involvement in sentence comprehension varied according to the combination of participant groups, sentence types, and patterns. The results suggest that both children with ID and TD relied on agent bias, whereby children consider the first noun to denote the actor and a word order strategy of interpreting a sequence of two noun phrases followed by the transitive verb as agent – patient – act. Furthermore, phonological memory underpins understanding of the relationships among arguments, particularly in the case of sentences for which agent bias or word order strategy may result in misinterpretation.

Syntactic analysis and semantic plausibility provide important cues to build the meaningful representation of sentences. The purpose of this research is to explore the age-related differences in the use of syntactic analysis and semantic plausibility during sentence comprehension under different working memory load conditions. A sentence judgment task was implemented among a group of older and younger adults. Semantic plausibility (plausible, implausible) and syntactic consistency (consistent, inconsistent) were manipulated in the experimental stimuli, and working memory load (high, low) was varied by manipulating the presentation of the stimuli. The study revealed a stronger effect of semantic plausibility in older adults than in younger adults when working memory load was low. But no significant age difference in the effect of syntactic consistency was discovered. When working memory load was high, there was a stronger effect of semantic plausibility and a weaker effect of syntactic consistency in older adults than in younger adults, which suggests that older adults relied more on semantic plausibility and less on syntactic analysis than younger adults. The findings indicate that there is an age-related increase in the use of semantic plausibility, and a reduction in the use of syntactic analysis as working memory load increases.

Recent artificial neural networks that process natural language achieve unprecedented performance in tasks requiring sentence-level understanding. As such, they could be interesting models of the integration of linguistic information in the human brain. We review works that compare these artificial language models with human brain activity and we assess the extent to which this approach has improved our understanding of the neural processes involved in natural language comprehension. Two main results emerge. First, the neural representation of word meaning aligns with the context-dependent, dense word vectors used by the artificial neural networks. Second, the processing hierarchy that emerges within artificial neural networks broadly matches the brain, but is surprisingly inconsistent across studies. We discuss current challenges in establishing artificial neural networks as process models of natural language comprehension. We suggest exploiting the highly structured representational geometry of artificial neural networks when mapping representations to brain data. [ABSTRACT FROM AUTHOR]

BackgroundAimsMethods & proceduresOutcomes and resultsConclusionsOne of the impairments in comprehension mostly reported for aphasia is that in reversible passive sentences, where a systematic asymmetry with reversible active sentences has been attested across languages. In several accounts, this selective impairment has been proposed to be the result of the specific syntax of passive sentences. However, some results particularly from flexible word order languages suggest that a pattern where both active and passive sentences are impaired also exists.In this study, we examined the actives and passives in the comprehension of a flexible word order language, namely standard Malay, in people with aphasia (PWA), aiming to confirm that the predominant pattern in this language is one of generalised impairment across reversible sentences (active and passive), and not an asymmetrical one. The role of fluency in determining the pattern of impairment was also explored.Fourteen healthy adults and 20 PWA, 14 with fluent aphasia and 6 with non-fluent aphasia, took part in a comprehension study in standard Malay. Standard Malay is a flexible word order language that relies on the parsing of the voice affix on the verb to correctly interpret both active and passive sentences. Participants were tested on a sentence-picture matching task on comprehension of active and passive reversible clauses.The study revealed that PWA were overall less accurate than healthy speakers in comprehension of reversible active and passive sentences, and non-fluent PWA were less accurate than fluent PWA with no effect of sentence type (active/passive). While not predominant, an asymmetric pattern was present in some participants. We propose that an impairment in thematic role assignment leads to a generalised impairment in comprehension of reversible sentences, while preserved thematic role mapping and impaired syntax lead to an asymmetric impairment.The study confirmed that speakers of Malay mostly show a generalised impairment in both active and passive sentences. Given the nature of the language, we propose that this suggests that impairment in Malay is predominantly shown on affix integration, first in mapping of thematic roles, and then in the full syntactic processing.

While a large body of work in sentence comprehension has explored how different types of linguistic information are used to guide syntactic parsing, less is known about the effect of discourse structure. This study investigates this question, focusing on the main and subordinate discourse contrast manifested in the distinction between restrictive relative clauses (RRCs) and appositive relative clauses (ARCs) in American English. In three self‐paced reading experiments, we examined whether both RRCs and ARCs interfere with the matrix clause content and give rise to the agreement attraction effect. While the standard attraction effect was consistently observed in the baseline RRC structures, the effect varied in the ARC structures. These results collectively suggest that discourse structure indeed constrains syntactic dependency resolution. Most importantly, we argue that what is at stake is not the static discourse structure properties at the global sentence level. Instead, attention should be given to the incremental update of the discourse structure in terms of which discourse questions are active at any given moment of a discourse. The current findings have implications for understanding the way discourse structure, specifically the active state of discourse questions, constrains memory retrieval. [ABSTRACT FROM AUTHOR]

As we interpret language moment by moment, we often encounter conflicting cues in the input that create incompatible representations of sentence meaning, which must be promptly resolved. Although ample evidence suggests that cognitive control aids in the resolution of such conflict, the methods commonly used to assess cognitive control's involvement in language comprehension provide limited information about the time course of its engagement. Here, we show that neural oscillatory activity in the theta-band (∼3–8 Hz), which is associated with cognitive control in nonlinguistic tasks like Stroop and Flanker, provides a real-time index of cognitive control during language processing. We conducted time-frequency analyses of four electroencephalogram data sets, and consistently observed that increased theta-band power was elicited by various kinds of linguistic conflict. Moreover, increases in the degree of conflict within a sentence produced greater increases in theta activity. These effects emerged as early as 300 ms from the onset of the initiating event, indicating rapid cognitive-control recruitment during sentence processing in response to conflicting representations. Crucially, the effect patterns could not be ascribed to processing difficulty that is not due to conflict (e.g., semantic implausibility was neither necessary nor sufficient to elicit theta activity). We suggest that neural oscillations in the theta-band offer a reliable way to test specific hypotheses about cognitive-control engagement during real-time language comprehension. Public Significance Statement: The results reported in this work provide the clearest evidence available that theta-band oscillations index cognitive control demands during language comprehension, thus extending previous findings that theta-band activity is elicited by representational conflict in cognitive tasks like Flanker and Stroop. Our findings support the growing body of work indicating that cognitive control plays a core role in ordinary language comprehension and provide a novel application of an established electrophysiological measure to study the real-time dynamics of cognitive control operations during sentence processing. The theta effects observed in this work, which appeared rapidly upon encountering the linguistic conflict, corroborate psycholinguistic models predicting that conflict during comprehension must be resolved quickly for successful communication.

Educators and researchers have been interested in supporting sentence-level language comprehension for struggling readers, but it has been challenging to research. To investigate the properties of sentences that might be useful targets for future research in instruction and assessment, we coded several features of the items in a computer-adaptive scale of sentence comprehension. The Syntactic Knowledge Task is designed for students in Grades 3–10. We then explored how the features of the sentences were related to the item's difficulty value to determine which aspects of sentence-level language made sentences more and less challenging for students across a range of development. We found that genre, words that represent a logical connection, number of idea units, long words, and words on the Academic Word List were significantly associated with item difficulty. Implications for understanding students' sentence-level language development are discussed. [ABSTRACT FROM AUTHOR]

What is the nature of lexical meanings such that they can both compose with others and also appear boundless? We investigate this question by examining the compositional properties of for‐time adverbial as in “Ana jumped for an hour.” At issue is the source of the associated iterative reading which lacks overt morphophonological support, yet, the iteration is not disconnected from the lexical meanings in the sentence. This suggests an analysis whereby the iterative reading is the result of the interaction between lexical meanings under a specific compositional configuration. We test the predictions of two competing accounts: Mismatch‐and‐Repair and Partition‐Measure. They differ in their assumptions about lexical meanings: assumptions that have implications for the possible compositional mechanisms that each can invoke. Mismatch‐and‐Repair assumes that lexical meaning representations are discrete, separate from the conceptual system from which they originally emerged and brought into sentence meaning through syntactic composition. Partition‐Measure assumes that lexical meanings are contextually salient conceptual structures substantially indistinguishable from the conceptual system that they inhabit. During comprehension, lexical meanings construe a conceptual representation, in parallel, morphosyntactic and morphophonological composition as determined by the lexical items involved in the sentence. Whereas both hypotheses capture the observed cost in the punctual predicate plus for‐time adverbial composition (e.g., jump (vs. swim) for an hour), their predictions differ regarding iteration with durative predicates; for example, swim for a year (vs. for an hour). Mismatch‐and‐Repair predicts contrasting processing profiles and nonoverlapping activation patterns along punctuality differences. Partition‐Measure predicts overlapping processing and cortical distribution profiles, along the presence of iterativity. Results from a self‐paced reading and an functional Magnetic Resonance Imaging (fMRI) studies bear out the predictions of the Partition‐Measure account, supporting a view of linguistic meaning composition in line with an architecture of language whereby combinatoriality and generativity are distributed, carried out in parallel across linguistic and nonlinguistic subsystems.

We used a novel nonword detection task to examine the lexical competition principle postulated in most models of spoken word recognition. To do so, in Experiment 1 we presented sequences of spoken words with half of the sequences containing a nonword, and the target nonword (i.e., press a response key whenever you detect a nonword in the sequence) could either be phonologically related (a phonological neighbor) or unrelated to the immediately preceding word. We reasoned that the reactivation of a phonological neighbor during target nonword processing should delay the moment at which a nonword decision can be made. Contrary to our hypothesis, participants were faster at detecting nonwords when they were preceded by a phonological neighbor compared with an unrelated word. In Experiment 2, an inhibitory effect of phonological relatedness on nonword decisions was observed in a classic priming situation using the same set of related and unrelated word-nonword pairs. We discuss the implications of these findings in regard to the main models of spoken word recognition, and conclude that our specific experimental set-up with phonological neighbors embedded in spoken sentences is more sensitive to cooperative interactions between co-activated sublexical representations than lexical competition between co-activated lexical representations, with the latter being modulated by whether or not the words compete for the same slot in time.

In recent years, there has been increasing interest in Rich Meaning Approaches (RMA) that understand the meanings of words as rich conceptual structures, such as Pustejovsky’s generative lexicon. The reason for this is based on compositionality, as rich meanings have been shown to be indispensable for explaining conflict resolution in compositional processes. However, while the benefits of postulating rich meanings to explain conflict resolution are undeniable, the overall contribution of rich meanings to sentence comprehension has not yet been discussed. This paper aims to show that inferentialism counts as a version of RMA and that, once this is recognised, it can provide a robust rationale for the role of rich meanings in sentence comprehension. The rationale is based on the idea that rich meanings are indispensable for pragmatic purposes as they play a role in facilitating communication. As I argue, rich meanings not only assist in composing the semantic (truth-conditional) content of complete sentences, but also provide crucial information for determining the discursive commitments and entitlements established by utterances. Consequently, examining the implications of inferentialism for compositional processes a) offers new insights into their function and outputs and b) presents an alternative to the representationalist perspective on sentence comprehension.

In this study, we investigated whether different morphosyntactic features, i.e. number and gender, play a role during the adult online comprehension of subject relative clauses (SRC) and object relative clauses (ORC), in Italian. This study was inspired by developmental studies showing that children struggle with ORC compared to SRC; yet, ORC comprehension improves if the head and the subject of the RC mismatch in relevant morphosyntactic features (e.g. number but not gender in Italian, based on the featural Relativized Minimality principle, fRM). We found that Italian adults read ORC more slowly than SRC verbs; moreover, ORC verbs were read faster in the head-subject number mismatch condition, while there was no facilitation in the head-subject gender mismatch condition, in line with developmental studies and fRM. We conclude that online parsing is feature-sensitive, that features are not all equally “relevant”, and that current models should be refined to account for these differences.

Introduction: This study examined whether visuospatial perspective uses the character perspective during narrative comprehension. Method: Participants read narrative stimuli depicting the spatial positional relationships between characters and objects and judged whether the objects were on the left or right from the character's perspective. We manipulated whether the spatial positional relationships between characters depicted in the narrative stimuli resulted in a visuospatial perspective. We hypothesized that the high-load perspective-taking condition would indicate longer reaction times compared to the low-load perspective-taking condition, as shifting perspectives between characters in the high-load condition require more time for visuospatial perspective-taking. Results: As predicted, the reaction time was longer for high-load perspective- taking than for low-load perspective-taking. Discussion: During narrative comprehension, the reaction time for visuospatial perspective-taking must move virtually within the representation from the main character's perspective to that of another character. Visuospatial perspective- taking is involved in narrative comprehension. [ABSTRACT FROM AUTHOR]

AbstractThree experiments were conducted to examine gullibility as measured by people’s bias to respond with a True response when performing sentence verification judgment task. The experiments manipulated the location of unfamiliar concepts such that some sentences contained unfamiliar concepts in the subject while other sentences contained unfamiliar concepts in the predicate, hence measuring the bias to judge an idea to be true when one cannot make the decision relying on background knowledge. The results indicated: 1) a higher frequency of True response when an unfamiliar concept is located in the subject compared to when it is in the predicate; and 2) the frequency of True response was lower than chance level even when unfamiliar information is located in the subject. The results were discussed in relation to gullibility and how the verification judgment is processed as a plausibility judgment. [ABSTRACT FROM AUTHOR]

The role of either short-term memory (STM) or working memory (WM) in sentence comprehension is a matter of debate. Although it is commonly accepted that memory resources are necessary for sentence comprehension, there is no agreement regarding the nature of their role. The aim of this review is to investigate and synthesize assessment tools and correlation data between STM or WM and sentence comprehension in probable Alzheimer's disease (AD). To this aim, a systematic review and meta-analysis of the literature was conducted according to the PRISMA guidelines. PubMed, Web of Science, Scopus, PsycInfo, and LLBA databases were searched. Two independent authors selected peer-reviewed articles published in English and focused on the relationship between STM or WM and sentence comprehension in probable AD. A total of 11 case–control studies were included at the end of the selection process. Most studies adopted offline tasks to evaluate sentence comprehension, while a small number of authors applied online experimental tasks. The digit span forward and backward were the most employed standardized tests to evaluate phonological STM and WM, respectively. The meta-analysis results supported the association between performance on STM and WM and comprehension tasks. However, moderate heterogeneity was found, mainly due to the small number of included studies, especially for STM, and the substantial variability of the adopted tasks. Therefore, in order to clarify the specific source of language comprehension deficits, new and sophisticated experiments should be conducted using adequate material. [ABSTRACT FROM AUTHOR]

Objectives: This study aimed to examine age-related differences in the comprehension of Korean comparative sentences with varying word orders by employing both offline and online measures, and to investigate how variations in word order affect sentence processing across different age groups. Methods: A total of 52 monolingual native Korean speakers, 26 young adults, and 26 older adults, completed a sentence-picture-matching task under two word order conditions: comparative-first and nominative-first. Offline measures included accuracy and response time, while an online method involved eye)tracking within the Visual World Paradigm. Data analyses were performed using linear and generalized linear mixed-effects models. Results: Older adults demonstrated lower accuracy and longer response times compared to younger individuals. Distinctive fixation patterns were observed, particularly in the sentential-final phrase, across different age groups. Specifically, nominative-first sentences elicited greater target advantage scores among younger adults, whereas older adults showed higher scores in comparative-first sentences. Conclusion: The study highlights the potential of comparative sentences in elucidating age-related changes in sentence comprehension. These differences were evident not only in offline tasks but also in real-time processing, as evidenced by eye-tracking data. The findings suggest distinct processing strategies employed by young and older adults and underscore the importance of considering both syntactic and semantic cues in sentence comprehension.

Sentence comprehension requires the integration of linguistic units presented in a temporal sequence based on a non-linear underlying syntactic structure. While it is uncontroversial that storage is mandatory for this process, there are opposing views regarding the relevance of general short-term-/working-memory capacities (STM/WM) versus language specific resources. Here we report results from 43 participants with an acquired brain lesion in the extended left hemispheric language network and resulting language deficits, who performed a sentence-to-picture matching task and an experimental task assessing phonological short-term memory. The sentence task systematically varied syntactic complexity (embedding depth and argument order) while lengths, number of propositions and plausibility were kept constant. Clinical data including digit-/ block-spans and lesion size and site were additionally used in the analyses. Correlational analyses confirm that performance on STM/WM-tasks (experimental task and digit-span) are the only two relevant predictors for correct sentence-picture-matching, while reaction times only depended on age and lesion size. Notably increasing syntactic complexity reduced the correlational strength speaking for the additional recruitment of language specific resources independent of more general verbal STM/WM capacities, when resolving complex syntactic structure. The complementary lesion-behaviour analysis yielded different lesion volumes correlating with either the sentence-task or the STM-task. Factoring out STM measures lesions in the anterior temporal lobe correlated with a larger decrease in accuracy with increasing syntactic complexity. We conclude that overall sentence comprehension depends on STM/WM capacity, while increases in syntactic complexity tax another independent cognitive resource.

Abstract The putamen is a subcortical structure. However, neuroimaging studies have demonstrated the involvement of the left putamen in other language functions such as bilingual language processing. Some studies have also shown the role of the right putamen in higher-order language functions. The present reanalysis aims to investigate the role of the bilateral putamen during the L1-L2 sentence comprehension in bilinguals using functional magnetic resonance imaging (fMRI). Hence, 36 Turkish-Persian bilinguals (21 females and 15 males), who had acquired their second language at the age of seven after entering school, were selected in a purposive sampling method to perform an auditory grammaticality judgment task within an alternative language switching paradigm. After detecting the activity of the bilateral putamen at the whole-brain level, in FSL, percent signal change was extracted per participant as an intensity measure and analyzed statistically in SPSS. At the whole-brain level, the findings demonstrated that the bilateral putamen was involved in the comprehension of syntactic structures during the alternating presentation of L1 and L2 stimuli. In addition, regardless of the hemisphere involved, the significant grammaticality effect for L1 as well as the increased sensitivity for L1-violation stimuli compared to L2-violation stimuli may imply the standard language dominance effect also in the putamen. Keywords: Bilingualism, Sentence comprehension, Putamen, L1, fMRI Introduction Subcortical structures are considered a key component in language processing in bilinguals. Basal ganglia are a group of subcortical structures found deep within the White Matter of the brain and have extensive connections with the cerebral cortex, especially Broca's area and speech motor cortex. These nuclei include Putamen, Caudate, Pallidum, substantia nigra and subthalamic. Nowadays, the involvement of Putamen in production processes is evidenced, nevertheless, very little is known about the contribution of this region in understanding syntax in bilinguals. To our knowledge, no studies have examined the role of Putamen in syntactic processing in bilinguals. Here, we aimed to explore it within an alternative language switching paradigm. To address this gap, the current reanalysis focuses on the following research question. How is the performance of bilateral Putamen during L1-L2 syntactic processing? To answer this research question guiding this study, a bilingual task with alternating language switching paradigm were developed. In this task, brain imaging was performed using event-related fMRI while the participants listened to a total of 128 sentences in two Turkish and Persian languages. Materials and methods To allow for reliable ROI-based analysis, 36 right-handed and balanced Turkish-Persian bilingual students were recruited to participate in this study. All participants were native speakers of Turkish and learned Persian at school from the age of seven. Participants' language proficiency levels were assessed by the Bilingual Dominance Scale (BDS) and no significant difference was observed between Turkish and Persian (i.e., between L1 and L2) in language dominance. During a bilingual grammaticality judgement task, participants heard 128 test sentences (64 in L1 and 64 in L2, with 50% violation per language) and made their judgment by pressing a button. Stimuli were presented using the Psychtoolbox in MATLAB via headphones. Stimuli were randomized for each condition, but alternated in a fixed sequence for language. MRI data were collected in NBML, Tehran, Iran, using a Siemens Prisma 3T scanner with a 20-channel head coil. For each participant, a high-resolution T1-weighted anatomical scan was acquired (TR = 1800msec, TE = 3053 msec, flip angle: 7°, 192 axial slices, slice thickness = 1 mm, field of view (FOV) = 256 mm2, 256 × 256 acquisition matrix, voxel size: 1×1×1 mm). After the anatomical scan, participants underwent a 21.5-min fMRI scan that used a whole brain echo planar imaging (EPI) sequence (TE: 30 ms, TR: 3000 ms, flip angle: 90°, slice thickness: 3 mm, voxel size: 3×3×3 mm, matrix size: 64×64, FOV: 192 mm2, 430 volumes and 45 axial slices per volume). Processing of the fMRI data was carried out using FEAT in FSL. Preprocessing steps included motion correction, slice-timing correction, non-brain removal using BET, spatial smoothing (6 mm FWHM), normalization, temporal filtering (with sigma = 50.0 s), and exploratory ICA-based data analysis. Statistical analyses of fMRI data were conducted using general linear modeling (GLM), as implemented in FSL. Z statistic images were thresholded using clusters determined by Z > 2.6 and a (corrected) cluster significance threshold of P < 0.05. After detecting the Cerebellum activation in the whole-brain analysis, percent signal changes were extracted as an intensity measure in this brain region. All statistical analyses were conducted in IBM SPSS Statistics 26. Discussion of results and conclusions The present reanalysis investigate the contribution of Putamen in Turkish-Persian participants during processing syntax. Our research question concerns whether there are differences in syntactic processing between L1 and L2 in bilateral Putamen in non-native participants. At the whole-brain level, the findings indicated that the bilateral Putamen is involved in modulating the syntactic aspects of language, supporting the previous pathological studies on Putamen as well as its association with cortical areas in the realm of bilingualism. Another crucial point is regarding the significant effect of grammaticality in L1 and significant differences between L1-ungrammatical and L2-ungrammatical sentences, irrespective of the involved hemisphere. This is in line with the behavioral performance of present sample in which bilinguals had longer reaction time and more errors for L1 which was leading to more brain activations. This could be arguably because of the standard language dominance effect placed on L1, as mentioned by Declerck & Koch (2023), demonstrating that the present population may have relied more on their L1 than L2. Accordingly, using Chinese-English bilingual speakers, Wang and his colleagues (2009) found that sustained and transient language control induced differential activation patterns, and that sustained and transient activities in the human brain modulate the behavioral costs during switching-related language control. Thus, it is reasonable to say that in mixed-language blocks, balanced bilinguals performed better in L1 than in L2. In sum, based on current sample and task, we propose that bilinguals who had learnt L2 at the age of seven when entering school have employed the bilateral Putamen during processing syntax with standard language dominance effect (i.e., better performance in L1 than in L2).

The ability to think about nonpresent time is a crucial aspect of human cognition. Both the past and future imply a temporal displacement of an event outside the "now." They also intrinsically differ: The past refers to inalterable events; the future to alterable events, to possible worlds. Are the past and future processed similarly or differently? In this study, we addressed this question by investigating how Spanish speakers process past/future time reference violations during sentence processing, while recording eye movements. We also investigated the role of verbs (in isolation; within sentences) and adverbs (deictic; nondeictic) during time processing. Existing accounts propose that past processing, which requires a link to discourse, is more complex than future processing, which-like the present-is locally bound. Our findings show that past and future processing differs, especially at early stages of verb processing, but this difference is not limited to the presence/absence of discourse linking. We found earlier mismatch effects for past compared to future time reference in incongruous sentences, in line with previous studies. Interestingly, it took longer to categorize the past than the future tense when verbs were presented in isolation. However, it took longer to categorize the future than the past when verbs were presented in congruous sentences, arguably because the future implies alterable worlds. Finally, temporal adverbs were found to play an important role in reinspection and reanalysis triggered by the presence of undefined time frames (nondeictic adverbs) or incongruences (mismatching verbs).

Empirical studies have found a processing asymmetry between Chinese subject-extracted relative clauses (SRCs) and object-extracted relative clauses (ORCs). Still, there is no consensus on how this SRC-ORC asymmetry occurs. Thus, aiming to elucidate how the neural activity, in the forms of both event-related potentials (ERPs) and brain oscillations (i.e. event-related synchronisation/desynchronisation, ERS/ERD), attuned to sentences with different levels of processing difficulty, we conducted an electroencephalography (EEG) study to examine the comprehension of Chinese SRCs and ORCs. The results showed an N400 and a P600 effect when comparing SRCs and ORCs. Simultaneously, delta ERS was associated with N400 during the processing of both types of relative clauses and theta ERS with P600 during the processing of SRCs. By incorporating the ERP and ERS indexes, we propose that the dissociation between the integration and retrieval effort involved in sentence comprehension may account for the processing asymmetry between sentences.

Comprehension of sentences with a center-embedded, object-gapped relative clause (ORC) is challenging for children as well as adults. Mismatching lexical and grammatical features of subject noun phrases (NPs) across the main clause and relative clause has been shown to facilitate comprehension. Adani et al. concluded that children's comprehension improved under conditions of NP number mismatch (e.g., singular main clause subject and plural relative clause subject) as compared with NP number match (e.g., both singular subjects). However, their stimuli provided number information on verb phrases (VPs) as well as NPs creating a confound for conclusions about facilitative effects of NP number mismatch. In this study, we isolated the contribution of NP number mismatch. Notably, 32 6-year-olds with typical language participated in a center-embedded, ORC sentence comprehension task with 4 types of stimuli: (a) NP number mismatch without VP number information (NP mismatch only), (b) NP number match without VP number information (NP match only), (c) NP number mismatch with VP number mismatch (NP + VP mismatch), and (d) NP number match with VP number match (NP + VP match). Children selected one of four pictures in an array to a verbally presented relative clause sentence; 56 sentences were presented. The within-subjects comparison for NP mismatch only and NP match only was not significant. However, the within-subjects comparison for NP mismatch only and NP + VP mismatch was significant. Children were more successful in NP + VP mismatch sentence comprehension ( r C = 0.70). [ABSTRACT FROM AUTHOR]

The analysis of the relationships between cognitive reserve and different cognitive domains has become a matter of interest since it can help us detect deviations from the typical ageing process. The main objective of our study was to analyse a structural equation model representing cognitive reserve's relationships with three cognitive domains (episodic memory, working memory, and sentence comprehension) in older adults with subjective cognitive decline and mild cognitive impairment patients, in a cross-sectional study. A total of 266 Spanish-speaking older adults, from 65 to 80 years old, voluntarily participated in the study. The assessment protocol includes questionnaires as well as screening and domain-specific tests, providing relevant information for the classification of participants in the two groups previously mentioned (n1 = 150 and n2 = 116). The proposed model presented metric and configural invariance as well as stability across groups, since the indices reflecting goodness-of-fit reach acceptable values. Our hypotheses are partially confirmed since cognitive reserve strongly influences working memory and it does moderately in sentence comprehension in both groups, but it hardly influences episodic memory in the subjective cognitive decline group, while both are inversely associated in the patients' group. Working memory could be considered as a mechanism through which cognitive reserve exerts its protector role on other cognitive domains: on sentence comprehension in both groups, and on episodic memory in the subjective cognitive decline group. However, in mild cognitive impairments patients, cognitive reserve does no longer influence episodic memory via working memory in a significant manner. [ABSTRACT FROM AUTHOR]

This study investigated the engagement of domain-general cognitive control during the comprehension of dense code-switching sentences. Stimulus-locked event-related potentials (ERPs) were measured while L1-dominant Chinese–English bilinguals read switch and non-switch sentences. The results of the reading task revealed language dominance effects on the N400, left anterior negativity (LAN) and late positive component (LPC). The language dominance effects at lexical level (i.e., on the N400 and LAN) were modulated by individual differences in monitoring capacity. In contrast, inhibition capacity predicted code-switching costs at the sentence level (i.e., for the LPC component). The results suggest that proactive monitoring and reactive inhibition affect different processing stages during the comprehension of dense code-switching sentences. These findings partially align with processing models of code-switching incorporating a dual control mode perspective and contribute new insight into the dynamic interplay between reactive and proactive control processes.

Many people with aphasia (PWA) show deficits in sentence production and comprehension, in part, due to an inefficient mapping between messages and syntactic structures. Structural priming—the tendency to repeat previously encountered sentence structures—has been shown to support implicit syntactic learning within and across production and comprehension modalities in healthy adults. Structural priming is also effective in facilitating sentence production and comprehension in PWA. However, less is known about whether priming in one modality changes PWA's performance in the other modality, crucial evidence needed for applying structural priming as a cost-effective intervention strategy for PWA. This study examined (a) whether production to comprehension cross-modality priming is effective in PWA, (b) whether priming-induced changes in syntactic comprehension lasted in the absence of an immediate prime, and (c) whether there is a significant correlation between individuals' priming effects and the change in their comprehension following priming. Thirteen PWA and 13 age-matched control participants completed a pre-test, a production-to-comprehension priming block, and a post-test. In the pre- and post-tests, participants completed a sentence-picture matching task with sentences involving interpretations of an ambiguous prepositional phrase (e.g., The teacher is poking the monk with a bat). Participants were free to choose a picture corresponding to a high attachment (HA; e.g., the teacher is using the bat to poke the monk) or a low attachment (LA; e.g., the monk is holding the bat) interpretation. In the priming block, participants produced LA sentences as primes and then completed a sentence-picture matching task for comprehension targets, similar to the pre-test. Age-matched controls and PWA showed a significant priming effect when comparing the priming block to the pre-test. In both groups, the priming effect persisted when comparing picture selections in the pre- and post-tests. At the individual level, age-matched controls who showed larger priming effects also selected more LA pictures in the post-test compared to the pre-test, indicating that the priming effect accounted for the magnitude of change from the pre- to post-test. This correlation was also found in PWA. These findings suggest that production-to-comprehension structural priming is effective and persistent in PWA and controls, in line with the view that structural priming is a form of implicit learning. Further, the findings suggest that syntactic representations are shared between modalities, and therefore, production influences future comprehension. Cross-modality structural priming may have clinical potential to improve sentence processing in PWA. [ABSTRACT FROM AUTHOR]

Comprehenders across languages tend to interpret role-ambiguous arguments as the subject or the agent of a sentence during parsing. However, the evidence for such a subject/agent preference rests on the comprehension of transitive, active-voice sentences where agents/subjects canonically precede patients/objects. The evidence is thus potentially confounded by the canonical order of arguments. Transitive sentence stimuli additionally conflate the semantic agent role and the syntactic subject function. We resolve these two confounds in an experiment on the comprehension of intransitive sentences in Basque. When exposed to sentence-initial role-ambiguous arguments, comprehenders preferentially interpreted these as agents and had to revise their interpretation when the verb disambiguated to patient-initial readings. The revision was reflected in an N400 component in ERPs and a decrease in power in the alpha and lower beta bands. This finding suggests that sentence processing is guided by a top-down heuristic to interpret ambiguous arguments as agents, independently of word order and independently of transitivity.

This study attempted to examine the impacts of conceptual and perceptual primes on the word recognition and sentence comprehension of beginner, intermediate and advanced EFL learners. Consequently, 246 EFL learners were recruited for study and categorized into three English proficiency levels. The needed data was collected via Lexical Decision Tasks (LDTs) and a constructed multiple-choice sentence comprehension test. The findings indicated that both priming techniques improved word recognition and sentence comprehension of the participants significantly, however the conceptual primes were more facilitative for both word recognition and sentence comprehension tasks. Moreover, language proficiency was found to be determinant of priming efficiency, in the way that, as the learners become more proficient their performance would be more positively affected by both conceptual and perceptual priming techniques. Finally, the pedagogical implications and suggestions are discussed in the light of the findings. [ABSTRACT FROM AUTHOR]

Multiple explanatory accounts of Tagalog word-order preferences have been proposed in the literature. We report three psycholinguistic experiments that investigate on-line comprehension patterns in Tagalog to illustrate the strength and consistency of two grammatical constraints in sentence processing (Bondoc and Schafer, 2022): a tendency for the agent to be placed in the first argument position (agent-first), and for the syntactically prominent argument (the pivot) to be placed in the second argument position (pivot-second). Our results show significant effects of these two constraints in the moment-by-moment reading of sentences, and also that their effects shift across measures and tasks. These outcomes contribute to the evidence of agent-first and pivot-second constraints influencing Tagalog word-order preferences and highlight their critical role in cognition and in Tagalog sentence processing.

This study investigates the role of sentence stress on the comprehension of sentences with clitic pronouns (unstressed morphemes and a typical feature of Romance languages) by children with cochlear implants (CIs). Thirteen children (seven girls) with CIs and 15 children (seven girls) with NH between eight and 12 years who are monolingual speakers of Brazilian Portuguese participated on a computerized sentence comprehension task that involved manipulation of stress placement of possible antecedent words to clitic pronouns. Children with CIs were significantly less accurate than children with NH in comprehending sentences with clitics, regardless of sentence stress. For children with NH, stress on the correct antecedent significantly increased sentence comprehension accuracy. For children with CI, there was no significant effect of sentence stress on selecting the correct antecedent for clitic pronouns. Comprehension of sentences with clitic pronouns is challenging for children with CIs and this challenge holds cross-linguistically. Furthermore, children with CIs do not use prosodic information to support comprehension of sentences with clitics similarly to NH children. Language-specific syntactic, morphosyntactic, and prosodic contrasts affecting sentence comprehension need to be assessed in children with CIs to plan an effective intervention.

Data from 996 Italian-speaking children were collected and analyzed to assess whether a movement-based notion of grammatical complexity is adequate to capture the developmental trend of clitics and passives in Italian. A second goal of the study was to address the relationship between working memory and syntactic development, exploring the hypothesis that higher digit span values predict better comprehension of complex matrix sentences. The results confirm the validity of a ranking of grammatical structures based on constituent movement, with both clitics and passives developing in parallel and later than canonical SVO sentences. Working memory also shows an effect on sentence comprehension in general, but standard measures (digit span forward/backward) do not show a selective advantage in handling complex constructions such as clitics and passives.

Several studies have reported subtle differences in cognition between individuals with subjective cognitive decline (SCD) compared to those with normal cognition. This study aimed to (i) identify these differences using discrepancy scores (e.g., categorial–phonemic verbal fluency performance) derived from neuropsychological tests in three cognitive domains (memory: Wechsler’s Word List and Digits; executive functions: Stroop and verbal fluency; and language: BNT and ECCO_Senior) and (ii) determine which discrepancy scores are significant for classification. Seventy-five older adults were included: 32 who were labeled SCD+ (age 71.50 ± 5.29), meeting Jessen et al.’s criteria, and 43 in the normal cognition group (SCD−; age 69.81 ± 4.62). Both groups completed a protocol including screening and the specified neuropsychological tests. No differences were found between the groups in their age, education, episodic memory, global cognitive state, or mood. Significant differences between the groups were observed regarding the discrepancy scores derived from BNT (naming) and ECCO_Senior (sentence comprehension). These scores accurately classified participants (71.6%), with ECCO_Senior having a primary role. ROC curves indicated a poor-to-fair model quality or diagnostic accuracy (AUC_BNT = 0.690; AUC_ECCO = 0.722). In conclusion, discrepancy scores in the language domain are important for distinguishing between individuals with SCD and normal cognition, complementing previous findings in this domain. However, given their relatively poor diagnostic accuracy, they should be used with caution as part of a more detailed neuro-psychological assessment.

Working memory (WΜ) components are investigated as correlates of complex sentence comprehension (cSC) in children, under the consideration of WM as a cognitive system of limited capacity. The present study aims to investigate the relationship between WM components and cSC in children of typical language development (TLD) as well as in children with Developmental Language Disorder (DLD), by systematically reviewing relevant studies. First, different tasks that are used to assess three distinct WM components are presented and task purity considerations on each of them are taken into account. Second, syntactically complex sentence types that are considered to constrain the already limited resources of WM are presented. Then, the systematic methods of the PRISMA-P protocol are followed. Based on them, six databases were thoroughly searched. After an initial screening stage and a final evaluation stage, twenty-eight studies were found to meet the inclusion criteria. Narrative synthesis was performed on the included studies. In TLD children, results on the role of verbal short-term memory (vST) and verbal working memory (vWM) in cSC are inconclusive, either supporting or questioning the capacity-limit approach. In DLD children, verbal working memory (vWM) has an important effect on cSC, rather than verbal short-term memory (vSTM). This suggests that a processing-execution component is important in DLD children’s cSC. For both children groups, a component serving as an interface between vSTM/vWM and long-term memory (vSTM/vWM-LTM) seems to play an important role; however, it is greatly understudied. Based on the results, future research directions and educational implications are suggested.

Introduction: Psycholinguistic research often focuses on Indo-European and other commonly studied major languages, while typologically diverse languages remain understudied. In this paper, we examine the morphological and conceptual influences on the real-time comprehension of optional plural-marked sentences in Yucatec Maya, an indigenous language of Mexico with a less commonly studied optional plural marking system. Methods: Fifty-one speakers of Yucatec Maya participated in a picture-sentence matching experiment carried out in the Yucatan Peninsula of Mexico. Pictures of one, two, or seven humans or animals depicting an intransitive action (conceptual number) were paired with auditorily presented sentences that had no plural marking, one plural, or two plurals (morphological number). Participants indicated by key press whether the picture and the sentence were an acceptable match, and decision time was recorded. Results: In the analysis of decision (yes versus no) and accuracy, morphological and conceptual factors interacted. In the analysis of decision time, however, morphological plural marking, but not conceptual number, led to faster decisions. Discussion: In light of previous work on the role of conceptual factors in the computation of number agreement, the interaction between conceptual and morphological factors suggests that a language with optional plural marking (or low "morphological richness") is associated with high conceptual influence on sentence comprehension. Importantly, the results of this study expand the empirical base of language types that have been investigated using psycholinguistic methods. [ABSTRACT FROM AUTHOR]

Many cross-language sentence processing studies showed structural priming, which suggests a shared representation across languages or separate but interacting representations for each language. To investigate whether multilinguals can rely on such representations to predict structure in comprehension, we conducted two visual-world eye-tracking priming experiments with Cantonese–Mandarin-English multilinguals. Participants were instructed to read aloud prime sentences in either Cantonese, Mandarin, or English; then they heard a target sentence in Mandarin while looking at the corresponding target picture. When prime and target had different verbs, there was within-language structural priming only (Mandarin-to-Mandarin, Experiment 1). But when prime and target had translation-equivalent verbs, there was not only within-language but also between-language priming (only Cantonese-to-Mandarin, Experiment 2). These results indicate that structure prediction between languages in comprehension is partly lexically-based, so that cross-linguistic structural priming only occurs with cognate verbs.

Objective: Parkinson's disease patients with subjective cognitive decline (PD-SCD) and mild cognitive impairment (PD-MCI) have an increased risk of dementia (PDD). Thus, the identification of early cognitive changes that can be useful predictors of PDD is a highly relevant challenge. Posterior cortically based functions, including linguistic processes, have been associated with PDD. However, investigations that have focused on linguistic functions in PD-MCI are scarce and none of them include PD-SCD patients. Our aim was to study language performance in PD-SCD and PD-MCI. Moreover, language subcomponents were considered as predictors of PDD. Method: Forty-six PD patients and twenty controls were evaluated with a neuropsychological protocol. Patients were classified as PD-SCD and PD-MCI. Language production and comprehension was assessed. Follow-up assessment was conducted to a mean of 7.5 years after the baseline. Results: PD-MCI patients showed a poor performance in naming (actions and nouns), action generation, anaphora resolution and sentence comprehension (with and without center-embedded relative clause). PD-SCD showed a poor performance in action naming and action generation. Deficit in action naming was an independent risk factor for PDD during the follow-up. Moreover, the combination of deficit in action words and sentence comprehension without a center-embedded relative clause was associated with a greater risk. Conclusions: The results are of relevance because they suggest that a specific pattern of linguistic dysfunctions, that can be present even in the early stages of the disease, can predict future dementia, reinforcing the importance of advancing in the knowledge of linguistic dysfunctions in predementia stages of PD.

Background: The comprehension profile of people with agrammatism is a debated topic. Syntactic complexity and cognitive resources, in particular phonological short‐term memory (pSTM), are considered as crucial components by different interpretative accounts. Aim: To investigate the interaction of syntactic complexity and of pSTM in sentence comprehension in a group of persons with aphasia with and without agrammatism. Methods & Procedures: A cohort of 30 participants presenting with aphasia was assessed for syntactic comprehension and for pSTM. A total of 15 presented with agrammatism and 15 had fluent aphasia. Outcomes & Results: Linear nested mixed‐model analyses revealed a significant interaction between sentence type and pSTM. In particular, participants with lower pSTM scores showed a reduced comprehension of centre‐embedded object relatives and long coordinated sentences. Moreover, a significant interaction was found between sentence type and agrammatism, with a lower performance for passives within the agrammatic group. Conclusions & Implications: These results confirm that pSTM is involved in the comprehension of complex structures with an important computational load, in particular coordinated sentences, and long‐distance filler gap dependencies. On the contrary, the specific deficit of the agrammatic group with passives is a pure syntactic deficit, with no involvement of pSTM. [ABSTRACT FROM AUTHOR]

Language processing is predictive in nature. But how dopeople balance multiple competing options as they predictupcoming meanings? Here, we investigated whether readersgenerate graded predictions about grammatical gender ofnouns. Sentence contexts were manipulated so that theystrongly biased people's expectations towards two or morenouns that had the same grammatical gender (single biascondition), or they biased multiple genders from differentgrammatical classes (multiple bias condition). Ourexpectation was that unexpected articles should lead toelevated reading times (RTs) in the single-bias conditionwhen probabilistic expectations towards a particular genderare violated. Indeed, the results showed greater sensitivityamong language users towards unexpected articles in thesingle-bias condition, however, RTs on unexpected gender-marked articles were facilitated, and not slowed. Our dataconfirm that difficulty in sentence processing is modulatedby uncertainty about predicted information, and suggest thatreaders make graded predictions about grammatical gender.

Mild cognitive impairment (MCI) threatens a large percentage of the elderly population worldwide. Symptoms can also include language and speech difficulties. This article aims at speech/language comprehension difficulties at the sentence level in people with MCI, with the use of a case study. Sentence comprehension was examined in a female patient with amnestic MCI, by means of the Czech version of the Sentence Comprehension Test. Impaired comprehension of all sentence types was found, with a high need for repetition, as well as the influence of sentence complexity. The results show that limited cognitive resources are a reason for insufficient linguistic information processing. Thus, therapy focused on cognitive training will also improve or maintain language.

To understand language, we need to recognize words and combine them into phrases and sentences. During this process, responses to the words themselves are changed. In a step toward understanding how the brain builds sentence structure, the present study concerns the neural readout of this adaptation. We ask whether low-frequency neural readouts associated with words change as a function of being in a sentence. To this end, we analyzed an MEG dataset by Schoffelen et al. (2019) of 102 human participants (51 women) listening to sentences and word lists, the latter lacking any syntactic structure and combinatorial meaning. Using temporal response functions and a cumulative model-fitting approach, we disentangled delta- and theta-band responses to lexical information (word frequency), from responses to sensory and distributional variables. The results suggest that delta-band responses to words are affected by sentence context in time and space, over and above entropy and surprisal. In both conditions, the word frequency response spanned left temporal and posterior frontal areas; however, the response appeared later in word lists than in sentences. In addition, sentence context determined whether inferior frontal areas were responsive to lexical information. In the theta band, the amplitude was larger in the word list condition; 100 milliseconds in right frontal areas. We conclude that low-frequency responses to words are changed by sentential context. The results of this study show how the neural representation of words is affected by structural context and as such provide insight into how the brain instantiates compositionality in language.

Artificial neural networks (ANNs) are an emerging field with a positive and encouraging outlook. In education, it is postulated that attention and academic performance could explain reading outcomes. The main goal of this research was to study the predictive capacity of an ANN with a backpropagation algorithm by analysing the relationship between sentence and text reading comprehension efficiency, attentional variables and academic performance in third-grade primary school students (N = 183). A non-experimental approach was adopted, using a cross-sectional and ex post facto design. Ten schools (70% public) located in southeastern Spain participated. Test of Reading Efficacy (TECLE), d2 attention test and TALE-2000 were administered. The results revealed that it is possible to design a network capable of learning by itself to predict sentence comprehension. Students who were good readers obtained better grades, concentrated better, scanned the stimulus more attentively, obtained more correct answers and made fewer omissions. The conclusions concerned the ethical implications of AI and the need to introduce ANNs in initial teacher training. [ABSTRACT FROM AUTHOR]

Vulnerability of morphosyntactic production, including grammatical aspect, has been identified in at least some children with autism spectrum disorder (ASD) exposed to typologically different languages. However, Tovar et al. (2015) found strengths in comprehending grammatical aspect in English-exposed children with ASD, suggesting that the challenges in production are pragmatically based. Using the eye-movement measures of Intermodal Preferential Looking, this study further explored whether Mandarin-exposed preschoolers with ASD were able to map aspect morphemes onto their distinct meanings in comprehension, despite their apparent impairments in aspect production. The results revealed that a diverse sample of 2–6-year-old Mandarin-exposed children with ASD demonstrated similar patterns of comprehending the perfective morpheme le and the progressive morpheme zai as younger 1–3-year-old TD children, even though the children with ASD's vocabulary production scores were dramatically delayed. Specifically, both groups of children associated the perfective morpheme le with the completed action and the progressive morpheme zai with the ongoing action. Our findings suggest that despite their apparent deficits of using/producing grammatical aspect, comprehension of grammatical aspect is a strength in children with ASD across languages. Moreover, grammatical aspect appears to be preserved in children with ASD, despite their pragmatic deficits and vocabulary disadvantages. The experimental findings shed light on the sharp contrast between linguistic competence versus linguistic performance in autistic grammatical acquisition. Furthermore, the results highlight the dissociation between the grammatical vs. the pragmatic and lexical language modules in children with ASD. [ABSTRACT FROM AUTHOR]
