The ability to flexibly categorize object concepts is essential to semantic cognition because the features that make two objects similar in one context may be irrelevant and even constitute interference in another. Thus, adaptive behavior in complex and dynamic environments requires the resolution of feature-based interference. In the current case study, we placed visual and functional semantic features in opposition across object concepts in two categorization tasks. Successful performance required the resolution of functional interference in a visual categorization task and the resolution of visual interference in a functional categorization task. In Experiment 1, we found that patient D. A., an individual with bilateral temporal lobe lesions, was unable to categorize object concepts in a context-dependent manner. His impairment was characterized by an increased tendency to incorrectly group objects that were similar on the task-irrelevant dimension, revealing an inability to resolve cross-modal semantic interference. In Experiment 2, D. A.'s categorization accuracy was comparable to controls when lures were removed, indicating that his impairment is unique to contexts that involve cross-modal interference. In Experiment 3, he again performed as well as controls when categorizing simple concepts, suggesting that his impairment is specific to categorization of complex object concepts. These results advance our understanding of the anterior temporal lobe as a system that represents object concepts in a manner that enables flexible semantic cognition. Specifically, they reveal a dissociation between semantic representations that contribute to the resolution of cross-modal interference and those that contribute to the resolution of interference within a given modality.

Perception and memory are traditionally thought of as separate cognitive functions, supported by distinct brain regions. The canonical perspective is that perceptual processing of visual information is supported by the ventral visual stream, whereas long-term declarative memory is supported by the medial temporal lobe. However, this modular framework cannot account for the increasingly large body of evidence that reveals a role for early visual areas in long-term recognition memory and a role for medial temporal lobe structures in high-level perceptual processing. In this article, we review relevant research conducted in humans, nonhuman primates, and rodents. We conclude that the evidence is largely inconsistent with theoretical proposals that draw sharp functional boundaries between perceptual and memory systems in the brain. Instead, the weight of the empirical findings is best captured by a representational-hierarchical model that emphasizes differences in content, rather than in cognitive processes within the ventral visual stream and medial temporal lobe. Expected final online publication date for the Annual Review of Vision Science, Volume 9 is September 2023. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

The Circumplex Team Scan (CTS) assesses the degree to which a team’s interaction/communication norms reflect each segment (16th) of the interpersonal circle/circumplex. We developed and evaluated an abbreviated 16-item CTS-16 that uses one CTS item to measure each segment. Undergraduates ( n = 446) completing engineering course projects in 139 teams completed the CTS-16. CTS-16 items showed a good fit to confirmatory structural models (e.g., that expect greater positive covariation between items theoretically closer to the circumplex). Individuals’ ratings sufficiently reflected team-level norms to justify averaging team members’ ratings. However, individual items’ marginal reliabilities suggest using the CTS-16 to assess general circumplex-wide patterns rather than specific segments. CTS-16 ratings correlated with respondents’ and their teammates’ ratings of team climate (inclusion, justice, psychological safety). Teams with more extraverted (introverted) members were perceived as having more confident/engaged (timid/hesitant) cultures. Members predisposed to social alienation perceived their team’s culture as relatively disrespectful/unengaged, but their teammates did not corroborate those perceptions. The results overall support the validity and utility of the CTS-16 and of an interpersonal circumplex model of team culture more generally.

It has been well-established that the hippocampus supports spatial context and episodic memory. Although spatial context serves as a powerful cue for autobiographical episodic memory recall, an open question is how spontaneously provided spatial context contributes to long-term retention and how this is implicated by aging due to age-related hippocampal changes that may influence the relationship between spatial context and episodic richness. Here, we analyzed an extensive, longitudinal dataset containing narrative recall of over a thousand personally-experienced, real-world events from 29 older adults and 12 younger adults. Recall for these events was tested twice: first, an average of 6 weeks after the event occurred, and then again, an average of 22 weeks after the event occurred. We developed a novel scoring protocol to quantify spatial contextual details at initial recall and assessed episodic richness at both time points according to the Autobiographical Interview (Levine et al., 2002). We found that memories initially recalled with greater spatial context were remembered with greater episodic detail after a delay. Notably, this preservation of episodic richness was selective for memories initially recalled with low episodic details and was not revealed in memories with high episodic details. Moreover, this effect was stronger in younger adults compared to older adults. Thus, we provide evidence that greater spontaneous reinstatement of spatial context scaffolded long-term episodic richness of memories that needed the most support and that the spatial scaffold declined with aging. This work demonstrates that a robust spatial scaffold depends on the integrity of the hippocampus and inspires the design of interventions that leverage the spatial scaffold to ultimately preserve detail-rich recollections of the past.

Combining information from multiple senses is essential to object recognition. Yet how the mind combines sensory input into coherent multimodal representations – the multimodal binding problem – remains poorly understood. Here, we applied multi-echo fMRI across a four-day paradigm, in which participants learned 3-dimensional multimodal object representations created from well-characterized visual shape and sound features. Our novel paradigm decoupled the learned multimodal object representations from their baseline unimodal shape and sound features, thus tracking the emergence of multimodal concepts as they were learned by healthy adults. Critically, the representation for the whole object was different from the combined representation of its individual parts, with evidence of an integrative object code in anterior temporal lobe structures. Intriguingly, the perirhinal cortex – an anterior temporal lobe structure – was by default biased towards visual shape, but this initial shape bias was attenuated with learning. Pattern similarity analyses suggest that after learning the perirhinal cortex orthogonalized combinations of visual shape and sound features, transforming overlapping feature input into distinct multimodal object representations. These results provide evidence of integrative coding in the anterior temporal lobes that is distinct from the distributed sensory features, advancing the age-old question of how the mind constructs multimodal objects from their component features.

Justice should increase inclusion because just treatment conveys acceptance and enables social exchanges that build cohesion. Inclusion should increase justice because people can use inclusion as a convenient fairness cue. Prior research touches on these causal associations but relies on a thin conception of inclusion and neglects within-person effects. We analyze whether justice causes inclusion at the within-person level. Five waves of data were gathered from 235 college students in 38 entrepreneurial teams. Teams were similar in size, work experience, deadlines, and goals. General cross-lagged panel models indicated that justice and inclusion had a reciprocal influence on each other. A robustness check with random-intercept cross-lagged models supported the results. In the long run, reversion to the mean occurred after an effect decayed, suggesting that virtuous or vicious cycles are unlikely. The results imply that maintaining overall justice at the peer-to-peer level may lead to inclusion.

The Enduring Happiness and Continued Self-Enhancement (ENHANCE) program, a 12-week intervention, effectively enhances subjective wellbeing and reduces negative symptoms. The current study tested an abbreviated 7-week version, ENHANCE-II, that may better fit the needs and schedules of some people. In a longitudinal study, participants (n = 51) took part in the self-study program and completed psychological assessments at baseline, posttest, and follow up (5 weeks). Multilevel models were used to analyze the data, with treatment group data from ENHANCE treated as the comparison. Analyses showed improvements in all four outcomes: life satisfaction (statistically significant), positive affect, negative affect, and depression. These effects were about half as strong as those in ENHANCE, but this effect reduction was partially attributable to low adherence. Effects were much stronger among participants who adhered to the program, especially for negative symptoms. Although there were no assessments at later intervals, the study suggests that ENHANCE-II intervention is likely beneficial for participants who need brief programs.

When professors assign group work, they assume that peer ratings are a valid source of information, but few studies have evaluated rater consensus in such ratings. We analyzed peer ratings from project teams in a second-year university course to examine consensus. Our first goal was to examine whether members of a team generally agreed on the competence of each team member. Our second goal was to test if a target’s personality traits predicted how well they were rated. Our third goal was to evaluate whether the self-rating of each student correlated with their peer rating. Data were analyzed from 130 students distributed across 21 teams (mean team size = 6.2). The sample was diverse in gender and ethnicity. Social relations model analyses showed that on average 32% of variance in peer-ratings was due to “consensus,” meaning some targets consistently received higher skill ratings than other targets did. Another 20% of the variance was due to “assimilation,” meaning some raters consistently gave higher ratings than other raters did. Thus, peer ratings reflected consensus (target effects), but also assimilation (rater effects) and noise. Among the six HEXACO traits that we examined, only conscientiousness predicted higher peer ratings, suggesting it may be beneficial to assign one highly conscientious person to every team. Lastly, there was an average correlation of.35 between target effects and self-ratings, indicating moderate self-other agreement, which suggests that students were only weakly biased in their self-ratings.

Vision neuroscience has made great strides in understanding the hierarchical organization of object representations along the ventral visual stream (VVS). How VVS representations capture fine-grained visual similarities between objects that observers subjectively perceive has received limited examination so far. In the current study, we addressed this question by focussing on perceived visual similarities among subordinate exemplars of real-world categories. We hypothesized that these perceived similarities are reflected with highest fidelity in neural activity patterns downstream from inferotemporal regions, namely in perirhinal (PrC) and anterolateral entorhinal cortex (alErC) in the medial temporal lobe. To address this issue with functional magnetic resonance imaging (fMRI), we administered a modified 1-back task that required discrimination between category exemplars as well as categorization. Further, we obtained observer-specific ratings of perceived visual similarities, which predicted behavioural discrimination performance during scanning. As anticipated, we found that activity patterns in PrC and alErC predicted the structure of perceived visual similarity relationships among category exemplars, including its observer-specific component, with higher precision than any other VVS region. Our findings provide new evidence that subjective aspects of object perception that rely on fine-grained visual differentiation are reflected with highest fidelity in the medial temporal lobe.

Several studies suggest that college counselors believe anxiety has been rising in recent decades. However, these surveys do not allow counselors to give nuanced answers or explicate their reasons,...

The act of remembering an everyday experience influences how we interpret the world, how we think about the future, and how we perceive ourselves. It also enhances long-term retention of the recalled content, increasing the likelihood that it will be recalled again. Unfortunately, the ability to recollect event-specific details tends to decline with age, resulting in an impoverished ability to mentally re-experience the past. This shift has been linked to a corresponding decline in the distinctiveness of hippocampal memory representations. Despite these well-established changes, there are few effective cognitive behavioral interventions that target real-world episodic memory. We addressed this gap by developing a smartphone-based application called HippoCamera that allows participants to record labelled videos of everyday events and subsequently replay standardized, high-fidelity autobiographical memory cues. In two experiments, we found that older adults were able to easily integrate this non-invasive intervention into their daily lives. Using HippoCamera to repeatedly reactivate memories for real-world events improved episodic recollection and it evoked more positive autobiographical sentiment at the time of retrieval. In both experiments, these benefits were observed shortly after the intervention and again after a 3-month delay. Moreover, more detailed recollection was associated with more differentiated memory signals in the hippocampus. We conclude that using this smartphone application to systematically reactivate memories for recent real-world experiences can help to maintain a bridge between the present and past self in older adults.

In an article in Perspectives on Psychological Science, Roberts et al. (2020) analyzed racial representation among publications and authors within three fields of psychology. This commentary points to two aspects of that article that may inhibit proper interpretation of the findings. First, Roberts et al. do not present population base rates in U.S. demographics when drawing inferences. Specifically, they interpret their bibliometric analysis as indicating an over-representation of White authors in social and developmental psychology with no consideration of base rates. I demonstrate that when base rates are considered, the data show equal representation in the 1980s, 1990s, and 2000s, and White under-representation in the 2010s in both subfields. They also report a correlation between non-White editorship, non-White authorship, and non-White participant recruitment, and then suggest that editorship causes an increase in authorship and participant recruitment. They do not consider that demographic change—an overall increase in the proportion of non-Whites in the U.S.—is an alternative explanation for this phenomenon. Lastly, they claim that race is an unpopular topic but a comparative PsycInfo analysis shows race may be one of the most popular topics in psychology. Thus, there are alternative ways to interpret their data.

Justice should increase inclusion because just treatment conveys acceptance and enables social exchanges that build cohesion.

We analyze whether justice causes inclusion at the within-person level. Five waves of data were gathered from 235 college students in 38 entrepreneurial teams.

The results imply that maintaining overall justice at the peer-to-peer level may lead to inclusion.

Correct tooth position in all planes of space while respecting the boundaries of the underlying bone is important for stability of teeth after orthodontic treatment as well as the health of the supporting periodontium.1,2 The aim of this study was to determine: 1) if mandibular posterior teeth are more centered over basal bone when they are more upright or close to WALA Ridge norms proposed by Andrews3; 2) if mandibular posterior teeth are more centered in alveolar bone when they are more upright or close to the WALA Ridge norms; 3) if the estimated center of resistance mandibular posterior teeth is most often centered in alveolar bone; and 4) if the WALA Ridge is located at or near the estimated center of resistance of mandibular posterior teeth. A sample of 34 pre-treatment CBCT scans and mandibular casts of patients ages 12–18 were included in the study. CBCT scans were digitized and analyzed using the Carestream 3D Imaging Software Version 3.5.7. Casts were digitally scanned using the Ortho Insight 3D scanner. The WALA Ridge horizontal measurements were made using the Six Elements™ software (MotionView, Chattanooga, TN). The WALA Ridge vertical measurements were obtained from the casts using a digital caliper. Coronal CBCT images were used to measure tooth positions of pre-treatment mandibular posterior teeth relative to surrounding bone. Centeredness of teeth within the bone was quantified and compared to their inclination and to the WALA Ridge location: D1, D2, D3 and D4. Data were analyzed using the JMP version 10 SAS Software. Descriptive statistics were used to calculate the mean, standard deviation, minimum, and maximum values for the distance between WALA Ridge vertical and CR, D2, D3 and D4 for each of the posterior teeth. Single linear regression analysis was performed to evaluate the relationship between both the long axis inclination and WALA Ridge variables compared to the D1, D2, D3, variables. No statistical significance was found for centeredness of mandibular posterior teeth over basal bone when they were more upright or approached WALA Ridge norms. No statistical significance was found for centeredness of mandibular posterior teeth in alveolar bone when they were more upright or approached the WALA Ridge norms. Significant differences were found for the mandibular posterior teeth center of resistance being centered in the alveolar bone regardless of the long axis inclination or WALA Ridge norms (p-value

Posterior crossbite is one of the most frequently occurring malocclusions in adolescents with a prevalence of 7% to 23%. The most common form of posterior crossbite is a unilateral posterior crossbite with a functional side shift. It has been suggested that functional posterior crossbites (FUPXB) may result in right-to-left-side differences in the condyle fossa relationship, resulting in temporomandibular joint (TMJ) problems. The objective of this study was to determine if pathological position of the condyles can cause condylar signs or symptoms like degenerative joint disease (DJD) or juvenile condylar resorption (JCR), or if the position of the condyle is just an altered position within the TMJ. Sixty patients with an average age of 9.6years were randomly selected from the office of one of the investigators (T.S.). The study group consisted of 29 patients with a FUPXB and the control group had 31 patients with no posterior crossbite. All patients had multislice CT scans of the TMJ taken as part of the orthodontic records. Transverse widths were measured at the skeletal base and the dentoalveolar base. Molar inclinations, condylar angulations, condylar anterior joint space, superior joint space, and posterior joint space were measured. Independent sample t-tests were used to compare different measurements between groups and paired sample t-tests were used to compare differences within the same patient. Reliability of measurements were determined using pairwise correlation. For dentoalveolar measurements of transverse width, the maxillomandibular difference for the study group was -8.2 mm and for the control group was -4.0 mm. No significant differences were found between the molar inclinations, condylar width, angulation, or any joint space measurements between the two groups. A total of 61.3% of the subjects in the control group and 72.4% in the study group had a radiographic sign of joint disease. The lack of condylar positional differences between the control and crossbite groups suggests that TMJ signs and symptoms in the study group may be related to remodeling in the TMJ instead.

Smart cities promise to generate economic, social and environmental value through the seamless connection of urban services and infrastructure by digital technologies (Hollands 2008, Viitanen and Kingston 2014), but there is scant evidence concerning their ability to enhance social well-being, build just and equitable communities, reduce resource consumption and waste generation, improve environmental quality or lower carbon emissions (Cavada et al. 2015). This special issue addresses the gap between the pipedream and the practice of smart cities, focusing on the social and environmental dimensions of real smart city initiatives, and the possibilities that they hold for creating more equitable and progressive cities. We argue that social equity and environmental sustainability are neither a-priori absent nor de-facto present in technological designs of smart city initiatives, but have to be made, nurtured and maintained as they materialise in particular places. This is the ‘possibility’ alluded to in our title, and where the focus of the Special Issue on the gap between the pipedreams and practicalities of smart cities leads. In this introduction we unpack this argument in greater detail and situate our six contributions within it. (Less)

In an article in Perspectives on Psychological Science, Roberts et al. (2020) claimed there is significant racial inequality in the publication process within psychology. Roberts et al. raise important questions, but some of their conclusions are inadequately supported. Among other things, they claim to have demonstrated that there is racial inequality in psychological research but do not define a threshold to separate inequality from equality. In addition, Roberts et al. fail to account for population base rates in U.S. demographics when drawing inferences. Specifically, they interpret their bibliometric analysis as indicating an over-representation of White authors in social and developmental psychology with no consideration of base rates. I demonstrate that when base rates are considered, the data actually show equal representation in the 1980s, 1990s, and 2000s, and White under-representation in the 2010s in both subfields. They also report a correlation between non-White editorship, non-White authorship, and non-White participant recruitment, and then suggest that editorship causes an increase in authorship and participant recruitment. They do not consider that demographic change—an overall increase in the proportion of non-Whites in the U.S.—is a better explanation than psychological bias for this association. They claim that race is an unpopular topic but a comparative PsycInfo analysis shows race may be one of the most popular topics in psychology. Their method for assessing a focus on race is also downward biased.

Identifying what an object is, and whether an object has been encountered before, is a crucial aspect of human behavior. Despite this importance, we do not yet have a complete understanding of the neural basis of these abilities. Investigations into the neural organization of human object representations have revealed category specific organization in the ventral visual stream in perceptual tasks. Interestingly, these categories fall within broader domains of organization, with reported distinctions between animate, inanimate large, and inanimate small objects. While there is some evidence for category specific effects in the medial temporal lobe (MTL), in particular in perirhinal and parahippocampal cortex, it is currently unclear whether domain level organization is also present across these structures. To this end, we used fMRI with a continuous recognition memory task. Stimuli were images of objects from several different categories, which were either animate or inanimate, or large or small within the inanimate domain. We employed representational similarity analysis (RSA) to test the hypothesis that object-evoked responses in MTL structures during recognition-memory judgments also show evidence for domain-level organization along both dimensions. Our data support this hypothesis. Specifically, object representations were shaped by either animacy, real-world size, or both, in perirhinal and parahippocampal cortex, and the hippocampus. While sensitivity to these dimensions differed across structures when probed individually, hinting at interesting links to functional differentiation, similarities in organization across MTL structures were more prominent overall. These results argue for continuity in the organization of object representations in the ventral visual stream and the MTL.

Objectives Aging is associated with decreased recollection required to offset misleading effects of familiarity, as well as an increased mnemonic reliance on gist-based over detail-based information. We tested the novel hypothesis that age-related decrements in overriding familiarity can be eliminated under conditions in which gist-based information facilitates retrieval. Method Twenty-seven younger adults and 27 older adults viewed scenes from two categories in an incidental encoding phase. In a recognition phase, old scenes were intermixed with new scenes from the studied categories and an unstudied category, with each new scene reappearing after 4, 18, or 48 intervening scenes. Participants were to respond “yes” to old scenes, and “no” to new scenes, including their repetitions. Results Despite encoding the scenes similarly, older adults made more false endorsements of new and repeated new scenes from studied categories. Both groups, however, were equally unlikely to falsely recognize new and repeated new scenes from the unstudied category. Discussion When helpful gist and misleading familiarity collide, gist wins, and eliminates age-related increases in false recognition.

The growing controversy around the adverse impacts of sharing economy platforms, including Airbnb and Uber, has led to calls for more democratic models of platform governance. Advocates of democratic governance models claim that these could help to create a more sustainable sharing economy by ensuring that platforms promote social and environmental values alongside the instrumental values of the capitalist economy. Exploring this claim we bring together theories of platform governance, democratic organisational governance and the enactment of values in socio-technical systems, offering a conceptual framework for analysing emerging democratic models of platform governance. Applying this framework, we present a mixed methods case study focused on Freegle, a platform that enables people to gift unwanted consumer goods locally and one of very few platforms to have sustained a democratic governance model at scale. In particular, we explore the extent to which the social, environmental and instrumental values of platform users and owners have been accommodated in the governance of Freegle. Our findings are broadly supportive of the claims made by advocates of democratic platform governance, although in Freegle's case social and environmental values are rather better accommodated than instrumental values. While we are cautiously optimistic about the potential from a sustainability perspective of democratic platform governance models, we emphasise that major challenges are likely to be faced by those implementing these; and that such models should be complemented by government regulation of the sharing economy. © 2017 Elsevier Ltd

This paper describes operating results with vehicle–solar-grid integration at the GridSTAR facility of Pennsylvania State University. A Ford F-150 converted to a plug-in hybrid electric vehicle was interfaced with the grid via an electric vehicle photovoltaic (EVPV) installation. The EVPV used the vehicle battery to provide frequency regulation ancillary service to the grid overnight when the solar energy of a hypothetical solar array was less valuable than the ancillary service, and the vehicle battery and the solar inverter were otherwise underutilized. The objective is to create an incentive for electric vehicle and solar PV ownership by fully utilizing the vehicle battery and the PV inverter net metering connection to support the grid and earn revenue. The test plan simulated operation of a school bus, which appears to be a particularly suitable application of this technology. The results showed that the vehicle could provide frequency regulation service that meets the technical requirements for revenue generation.
