A longitudinal study analyzed (a) which lower- and higher-level semantic components uniquely predicted listening text comprehension and (b) the nature of the relation (i.e., direct and indirect) between the predictors and listening text comprehension in preschoolers. One-hundred and fifty-two children participated in the present study (68 females; mean age = 4;10 years/months and 5;5 years/months at Time 1 and Time 2, respectively). Participants were administered measures to evaluate listening text comprehension (Time 1 and Time 2) and (a) expressive and receptive word knowledge (lower-level semantic components), and (b) inferential skills and the ability to use context (higher-level semantic components) (Time 1). Verbal short-term and working memory were also included as control variables. Data were analyzed using path analysis models. Results showed that both types of semantic components (a) accounted for unique variance in listening text comprehension at Time 2, with lower-level semantic components explaining a larger proportion of variance than higher-level semantic components; (b) were related to later listening text comprehension through direct and indirect relations. Memory resources did not significantly contribute to listening text comprehension. The results are discussed in light of their theoretical relevance and educational/practical implications.

Two studies explored the relation between listening comprehension of text and listening comprehension of sentences in preschoolers aged 4 to 5 years, 11 months. The first study analyzed this relationship taking into account the role of lower level components, namely, word knowledge and verbal working memory, as possible mediators. These components specifically accounted for listening text comprehension, whereas sentence comprehension did not. Given that sentences forming a text are not processed in isolation but in context, the second study explored the role of the ability to use linguistic context, a higher level component, in listening comprehension of text and sentences. Listening sentence comprehension was facilitated by the use of context, which accounted for individual differences in listening text comprehension. Overall, results showed that listening text comprehension is related to lower level as well as higher level components, whereas listening sentence comprehension does not play a specific role.

The current study was designed to investigate the role played by verbal memory in the advantage shown by individuals with Down syndrome in reading over listening text comprehension (Roch & Levorato, 2009). Two different aspects of verbal memory were analyzed: processing load and coding modality. Participants were 20 individuals with Down syndrome, aged between 11 and 26 years who were matched for reading comprehension with a group of 20 typically developing children aged between 6;3 and 7;3 years. The two groups were presented with a listening comprehension test and four verbal memory tasks in which the degree of processing load and the coding modality were manipulated. The results of the study confirmed the advantage of reading over listening comprehension for individuals with Down syndrome. Furthermore, it emerged that different aspects of verbal memory were related respectively to reading and to listening comprehension: visual memory with low processing load was related to the former and oral memory with high processing load to the latter. Finally, it was demonstrated that verbal memory contributed to explain the advantage of reading over listening comprehension in Down syndrome. The results are discussed in light of their theoretical relevance and practical implications. (Contains 4 tables.)

According to multicomponent models (Oakhill & Cain, 2007a), text comprehension is a complex process that requires the processing of explicit (i.e., information presented in the text) and implicit information (i.e., information inferable from the text or from previous knowledge), and involves various components. This study investigated (a) preschoolers' understanding of explicit and implicit information in oral texts and (b) the role of verbal and inferential skills in the processing of explicit and implicit information. Two hundred twenty-one 4- to 6-year-olds were evaluated as to their listening text comprehension and the following components: receptive vocabulary, verbal intelligence, and inferential skills. Working memory was a control variable. Results showed that (a) explicit information was easier to process than implicit information; and (b) all the components considered, except receptive vocabulary, accounted for comprehension of both types of information, and their role was stable in the age range considered.

The contribution of lower level linguistic abilities (study 1) and a higher level capacity, namely the use of context, (study 2), on text comprehension was studied. Participants were 16 individuals with Down syndrome aged between aged between 8 years 11 months and 16 years 10 months, and 16 children with typical development, aged between 5 years 11 months and 7 years 3 months, matched for the level of text comprehension. In study 1 the two groups were compared for receptive vocabulary and sentence comprehension: both of them were shown to play a role in text comprehension in Down syndrome. Since participants with Down syndrome had very low scores in sentence comprehension, study 2 tested the hypothesis that when sentences were presented within a brief context, individuals with Down syndrome would perform better. This hypothesis was confirmed and it was shown that contextual facilitation was closely related to text comprehension skills. (Contains 3 notes, 2 tables and 1 figure.)

Background: According to the "Simple View of Reading" (Hoover and Gough 1990), individual differences in reading comprehension are accounted for by decoding skills and listening comprehension, each of which makes a unique and specific contribution. Aims: The current research was aimed at testing the Simple View of Reading in individuals with Down's syndrome and comparing their profiles with typically developing first graders. Methods & Procedures: Listening comprehension and the ability to read both words and non-words was compared in two groups with the same level of reading comprehension: 23 individuals with Down's syndrome aged between 11 years 3 months and 18 years 2 months and 23 first-grade typically developing children aged between 6 years 2 months and 7 years 4 months. Outcomes & Results: The results indicate that at the same level of reading comprehension, individuals with Down's syndrome have less developed listening comprehension and more advanced word recognition than typically developing first graders. A comparison of the profiles of the two groups revealed that reading comprehension level was predicted by listening comprehension in both groups of participants and by word-reading skills only in typically developing children. Conclusions & Implications: The Simple View of Reading model is confirmed for individuals with Down's syndrome, although they do not show the reading profile of typically developing first graders; rather, they show an atypical profile similar to that of "poor comprehenders" (Cain and Oakhill 2006). The crucial role of listening comprehension in Down's syndrome is also discussed with reference to the educational implications. (Contains 4 tables, 2 figures and 1 note.)

The relation between text and idiom comprehension in children with poor text comprehension skills was investigated longitudinally. In the first phase of the study, six-year-old first graders with different levels of text comprehension were compared in an idiom and sentence comprehension task. Text comprehension was shown to be more closely related to idiom comprehension than sentence comprehension. The follow-up study, carried out eight months later on less-skilled text comprehenders, investigated whether an improvement in text comprehension was paralleled by an improvement in idiom comprehension. The development of sentence comprehension was also taken into account. Children who improved in text comprehension also improved in idiom comprehension; this improvement was, instead, weakly related to an improvement in sentence comprehension. The relationship between text and idiom comprehension is discussed in the light of the Global Elaboration Model (Levorato & Cacciari, 1995).

According to a developmental model of figurative language acquisition--the "global elaboration model" (Levorato & Cacciari, 1995)--the metalinguistic awareness necessary to use figurative language in a creative way is acquired late, and is subsequent to the ability to comprehend and produce figurative expressions. One hundred and eight children aged 9;6, one hundred and twenty-four children aged 11;3, one hundred and twelve adolescents aged 18;5 and one hundred adults participated in Experiment 1 which studied the development of metalinguistic awareness through an elicitation task. The subjects produced a high percentage of figurative expressions with a clear developmental trend that is concluded in adolescence. In addition, Experiment 2 showed that the production of comprehensible, appropriate and novel metaphors, as they were rated by adult judges, also increased with age. These results show that the ability to use figurative language in a creative and sensible way requires a long developmental time span and is strictly connected with the ability to reflect on language as a complex cognitive and interpersonal phenomenon.

Investigates whether children's representations of the linguistic description of a goal-directed event was similar to their representation of the same event observed visually. Finds that mode of presentation did not affect the recall of most important actions, but that verbal description led to recall characterized by greater cohesion than visual presentation of the same event.

Presents a study of the acquisition and development of information coordination ability. Examines students' composition of texts comparing two cultural groups after reading either one text describing both or a separate text on each. Concludes that older students used more complex information integration levels, whereas all subjects performed better when presented with the single text. (DK)
