Children's comprehension and production of idioms: the role of context and familiarity.

Several studies have argued that children under the ages of nine or ten years rarely comprehend figurative language and therefore interpret it literally. Cacciari & Levorato (1989) showed that when idioms are presented within a rich informational environment, children are able to grasp the figurative sense at the age of seven, and also that children are less able to produce idioms than to comprehend them. In three experiments involving 264 children (whose age ranged from 6;9 to 11;9), we contrasted this global elaboration hypothesis with a partially alternative one, the acquisition via exposure hypothesis, according to which the frequency of exposure of children to idioms is the main factor explaining their acquisition and production. Results showed that familiarity (i.e. frequency of exposure) plays a minor role and only for children who are not yet able to use contextual information. Familiarity per se does not adequately explain how children acquire a figurative competence. A tentative model is proposed in order to account for figurative competence acquisition.

How Children Understand Idioms in Discourse.

Some studies have shown that children tend to interpret figurative language literally. Our hypothesis is that they can reach an idiomatic competence if idioms are presented within a rich informational environment allowing children to grasp their figurative sense. First and third graders were presented with narratives biased both to the figurative meaning of idioms (experiment 1) and to the literal meaning (experiment 2) and then given a comprehension task. Experiment 3 was designed to investigate childrens production of idioms as compared to the comprehension abilities explored in experiments 1 and 2. Results show that informative contexts can improve childrens ability to perceive idiomatic meanings even at the age of seven; and that children are less able to produce idioms than to comprehend them. Generally results emphasize that children seem able to perceive that language can be both figurative and literal.

Listening comprehension in preschoolers: The role of memory

The current study analyzed the relationship between text comprehension and memory skills in preschoolers. We were interested in verifying the hypothesis that memory is a specific contributor to listening comprehension in preschool children after controlling for verbal abilities. We were also interested in analyzing the developmental path of the relationship between memory skills and listening comprehension in the age range considered. Forty-four, 4-year-olds (mean age = 4 years and 6 months, SD = 4 months) and 40, 5-year-olds (mean age = 5 years and 4 months, SD = 5 months) participated in the study. The children were administered measures to evaluate listening comprehension ability (story comprehension), short-term and working memory skills (forward and backward word span), verbal intelligence and receptive vocabulary. Results showed that both short-term and working memory predicted unique and independent variance in listening comprehension after controlling for verbal abilities, with working memory explaining additional variance over and above short-term memory. The predictive power of memory skills was stable in the age range considered. Results also confirm a strong relation between verbal abilities and listening comprehension in 4- and 5-year-old children.

Role of Verbal Memory in Reading Text Comprehension of Individuals with Down Syndrome.

This study analyzed the relationship between verbal memory and reading text comprehension in individuals with Down syndrome. The hypothesis that verbal memory provides unique contribution to reading text comprehension after controlling for verbal skills was tested. Twenty-three individuals with Down syndrome (ages 11 years, 2 months-18 years, 1 month) were matched on reading text comprehension, which was the primary variable of interest, with 23 typically developing children (ages 6 years, 2 months-7 years, 1 month). The two groups were compared on verbal skills and verbal memory. The results showed that working memory (concurrent storage and processing functions), but not short-term memory, predicted unique variance in reading text comprehension, after the verbal skills were controlled for. No group differences emerged in the relationship between verbal memory and reading text comprehension.

Idiom understanding in children and adolescents with down syndrome: The role of text comprehension skills.

In the current study, idiom understanding was analyzed in relation to the ability to process the linguistic context in which the idiom is embedded with the hypothesis that there is a strong relationship between text and idiom comprehension. This hypothesis was derived from the global elaboration model. Nonfamiliar idioms, both transparent and opaque, were presented in the context of a story to 20 participants with Down syndrome aged between 9 years, 9 months (9;9) and 18;1 and to 20 first-grade typically developing children aged between 6;3 and 7;3 who had the same level of text comprehension. Results show that for both groups differences in idiom understanding can be accounted for by differences in text comprehension: the same relationship holds between idiom and text comprehension in Down syndrome and in typical development and is not influenced by idiom type (semantic analyzability) or by sentence comprehension. The results provide support to the global elaboration model and are discussed in light of it.

The semantic structure of vision verbs: A psycholinguistic investigation of Italian

The aim of the present study was to investigate the semantic dimensions that contribute to the mental representation of vision verbs in Italian. In Experiment 1, a group of experts (psychology faculty members) was asked to list the semantic attributes necessary for describing a set of Italian vision verbs (Phase 1) and a group of students rated the extent to which each of these attributes was appropriate to characterise these verbs (Phase 2). In Experiment 2, the conceptual organisation of vision verbs was assessed through Multidimensional Scaling (MDS) using direct judgements of pairwise similarity between vision verbs (e.g., “vedere-guardare”). The results show that six of the attributes generated in Phase 1 are useful for describing the pattern of similarity ratings obtained in Experiment 2, namely attention, certainty, cognitive content, control, duration, and intentionality.

Cognitive and Affective Responses to Structural Variations of An E. A. Poe Short Story

Two experiments studied reader responses to structurally different versions of a short story by E. A. Poe. It was modified by flashback and anticipation to produce four additional versions. In Experiment 1, the following responses were collected: Curiosity, Excitement, Imagery, Impact, Interest, Pleasure, Pleasure at the Ending, Surprise, Surprise at the Ending, Suspense; moreover, readers were asked to judge characteristics of the text, that is Coherence, Facility, and Postdictability. Results show that three dimensions underlie narrative reception: Involvement while Reading, Evaluation of the Outcome, and Cognitive Evaluation. In Experiment 2, at pre-established points, readers were asked to evaluate some responses belonging to the first dimension, namely Curiosity, Interest, Pleasure, and Excitement. The analyses show different trends in text reception according to text structure.

Verbal inflection, articles and object clitics in Italian specific language impairment.

Morphosyntactic skills in spontaneous and elicited production of a 7-year-old boy with specific language impairment (SLI) were examined and compared to those of younger, mean length of utterance (MLU)-matched, typically-developing children. This study focused on inflectional phrase structures as well as complex constructions in order to investigate hypotheses which suggest verbal inflection is a key deficit underlying SLI. It analysed the most affected morphemes in Italian: articles and direct and indirect object clitics. A deficit was found in verbal inflection as well as in articles and object clitics. The difficulties with verbal inflection found were expected given the childs MLU. Problems with articles and clitics were unexpected for MLU, presenting a challenge for hypotheses that focus on verbal inflection.

Understanding the semantic functions of but in middle childhood: The role of text- and sentence-level comprehension abilities

This study examined Italian 7- to 9-year-olds’ understanding of the connective but when used to relate two events in sentences embedded in short stories. Performance was largely accounted for by the cognitive complexity of the sentence that included the connective and the salience of its meaning (confirmed in a second study with adults). Additional influences on children’s performance were the category of the story in which the critical sentence was embedded and the child’s text comprehension abilities. Further, by 9 years of age, performance resembled that of adults. These findings make an advance in explaining the role of information presented in a text at different levels and an individual’s linguistic abilities in children’s understanding of the connective but in stories and its development.
