Use of Context in Question Answering By 3-, 4- and 5-Year-Old Children

This study investigates, within the theory of relevance of Sperber & Wilson (1995), how 3-, 4-, and 5-year-old children (n = 45) use context when answering questions. The children were required to answer questions that placed differing contextual and processing demands on them, as predicted by the theory. The results indicate that an increasing ability to use complex contextual information was related to age and was reflected in the childrens ability to answer questions appropriately. A developmental pattern became evident in terms of how the children assigned referents, enriched semantic underdetermination, and recovered implicatures. It also became evident that even at the age of 5 years 6 months the children were in the process of becoming more skilled at integrating contextually complex inferences. It was further shown how childrens selection of the appropriate context, given the focus of the question, depended on how relevance was achieved in that context.

The development of narrative productivity, syntactic complexity, referential cohesion and event content in four- to eight-year-old Finnish children

This study focuses on the development of narrative structure and the relationship between narrative productivity and event content. A total of 172 Finnish children aged between four and eight participated. Their picture-elicited narrations were analysed for productivity, syntactic complexity, referential cohesion and event content. Each measure showed a developmental trend. Concerning consecutive age groups, significant differences were observed between four- and five-year-olds in productivity and event content and between five- and six-year-olds in referential cohesion. Multiple regression analysis showed that the relationship between productivity and event content was important, and especially the number of different word tokens proved to be useful in explaining the event content, whereas the number of communication units did not. This suggests that some productivity measures should be interpreted with caution.

Comprehension of inferential meaning in language-impaired and language normal children

Three groups of language-normal (LN) 6, 8 and 16/17 year olds, and a group of language-impaired (LI) children were given a task answering questions about pictures that involved inferential meaning. A developmental progression in the types of responses given is seen, with the LI children performing like the youngest LN children. A similar progression is seen in the ability to justify the answers given to inferential questions with the young adult group giving the fewest justifications that were problematical in some way. Larger numbers of problematical justifications in the LI group can be related to some extent to non-pragmatic aspects of their impairment, but overall this group also gave more pragmatically irrelevant responses when asked to justify answers given. It was not possible to identify any major differences between subgroups of children within the LI group, identified as pragmatically impaired (PI) and non pragmatically impaired (NPI), in terms of either answers given to inferential questions or in terms of problematical justifications for these answers. Possible reasons for these findings are discussed.

Relevance theory and pragmatic impairment

This paper summarizes aspects of relevance theory that are useful for exploring impairment of pragmatic comprehension in children. It explores data from three children with pragmatic language difficulties within this framework. Relevance theory is seen to provide a means of explaining why, in a given context, a particular utterance is problematic. It thus enables one to move on from mere description of problematic behaviours towards their explanation. The theory provides a clearer delineation between the explicit and the implicit, and hence between semantics and pragmatics. This enables one to place certain difficulties more firmly within semantics and others within pragmatics. Relevance, and its maximization in communication, are squarely placed within human cognition, which suggests a close connection between pragmatic and cognitive (dis)functioning. Relevance theory thus emerges as a powerful tool in the exploration and understanding of pragmatic language difficulties in children and offers therapeutically valuable insight into the nature of interactions involving individuals with such impairments.

Children with specific language impairment in Finnish: the use of tense and agreement inflections.

Children with specific language impairment (SLI) vary widely in their ability to use tense/agreement inflections depending on the type of language being acquired, a fact that current accounts of SLI have tried to explain. Finnish provides an important test case for these accounts because: (1) verbs in the first and second person permit null subjects whereas verbs in the third person do not; and (2) tense and agreement inflections are agglutinating and thus one type of inflection can appear without the other. Probes were used to compare the verb inflection use of Finnish-speaking children with SLI, and both age-matched and younger typically developing children. The children with SLI were less accurate, and the pattern of their errors did not match predictions based on current accounts of SLI. It appears that children with SLI have difficulty learning complex verb inflection paradigms apart from any problem specific to tense and agreement.

Cognitive approach to assessing pragmatic language comprehension in children with specific language impairment

BACKGROUND Pragmatic language impairment in children with specific language impairment has proved difficult to assess, and the nature of their abilities to comprehend pragmatic meaning has not been fully investigated. AIMS To develop both a cognitive approach to pragmatic language assessment based on Relevance Theory and an assessment tool for identifying a group of children with pragmatic language impairment from within an specific language impairment group. METHODS & PROCEDURES The authors focused on Relevance Theorys view of the role of context in pragmatic language comprehension using questions of increasing pragmatic complexity in different verbal contexts (scenarios with and without pictures and a story with supporting pictures). The performances of the children with and without pragmatic impairment on the most pragmatically demanding Implicature questions were examined. This study included 99 children: 27 with specific language impairment (including nine pragmatically impaired children) and two groups of typically developing children (32 children aged 5-6 years and 40 children aged 7-11 years). OUTCOMES & RESULTS The specific language impairment group performed similarly to their peers when utilizing context in inferring referents, inferring semantic meaning, and generating Implicatures, only when the answer was provided by pictorial context. Both the children with specific language impairment and the 5-6 year olds were not yet competent at utilizing verbal context when answering the most pragmatically demanding questions (targeting Implicature). On these questions the children with pragmatic language impairment performed significantly poorer than the rest of the specific language impairment group and performance scores on Implicature questions were found to identify accurately the children with pragmatic language impairment from the rest of the specific language impairment group (sensitivity = 89%). CONCLUSIONS Childrens ability to infer and integrate information in the comprehension of pragmatic meaning was found to be influenced by the available context. As children become more competent they are able to utilize verbal context and integrate information. Children with specific language impairment and those with pragmatic language impairment were found to be developmentally delayed at making inferences, but children with pragmatic language impairment had particular difficulty in integrating contextual information. Findings support the view that a cognitive approach to assessing pragmatic comprehension deficits could provide clinicians with a useful tool.

Development of pragmatic language comprehension in Finnish-speaking children

This research explores the development of pragmatic comprehension within the framework of relevance theory. Participants were 210 typically developing Finnish children aged from 3 to 9 years. The children were asked questions targeting the pragmatic processes of reference assignment, enrichment and implicature, as proposed by relevance theory. Results indicate that increasing ability to use contextual information in comprehension is related to age. The largest increase in correct answers occurred between the ages of 3 and 4 years. Answering reference assignment questions was not problematic for any of the age groups. Answering enrichment and implicature questions reflected the childrens increasing ability to use more complex contextual information in the comprehension process. This supports the processing model suggested by relevance theory.

Linguistic and pragmatic aspects of narration in Finnish typically developing children and children with specific language impairment.

Abstract This study investigates narratives of Finnish children with specific language impairment (SLI) from linguistic and pragmatic perspectives, in order to get a comprehensive overview of these children’s narrative abilities. Nineteen children with SLI (mean age 6;1 years) and 19 typically developing age-matched children participated in the study. Their picture-elicited narrations were analysed for linguistic productivity and complexity, grammatical and referential accuracy, event content, the use of mental state expressions and narrative comprehension. Children with SLI showed difficulties in every aspect of narration in comparison to their peers. Only one measure of productivity, the number of communication units, did not reach statistical significance. Not only was linguistic structure fragile but also pragmatic aspects of storytelling (referencing, event content, mental state expressions and inferencing) were demanding for children with SLI. Results suggest that pragmatic aspects of narration should be taken into account more often when assessing narrative abilities of children with SLI.

Normal and language-impaired children's use of reference: syntactic versus pragmatic processing.

The present study investigates childrens syntactic and pragmatic processing when specifying referents presented in short video clips. Within Relevance theory, the assumption of ‘optimal relevance’ implies that utterances are intended to involve the least processing effort on the part of the listener. In the present context, lexically specified NPs are assumed to be more in line with optimal relevance than pronouns. Subjects were 48 normally developing children aged 3;4–8;10 and 30 SLI children aged 5;1–8;9, divided into a low and a normal MLU group. Childrens responses were coded according to levels of pragmatic processing and syntactic positions. Normally developing childrens referent specifications were found to be increasingly relevant with increasing age. Differences between SLI and normal children were only found for the low MLU group with SLI who used fewer pronouns than the younger children, thereby showing that syntactic limitations alone cannot account for childrens specification of referents.

Noun Case Suffix Use by Children with Specific Language Impairment: An Examination of Finnish.

Finnish-speaking children with specific language impairment (SLI, N = 15, M age = 5;2), a group of same-age typically developing peers (TD-A, N = 15, M age = 5;2) and a group of younger typically developing children (TD-Y, N = 15, M age = 3;8) were compared in their use of accusative, partitive, and genitive case noun suffixes. The children with SLI were less accurate than both groups of TD children in case marking, suggesting that their difficulties with agreement extend to grammatical case. However, these children were also less accurate in making the phonological changes in the stem needed for suffixation. This second type of error suggests that problems in morphophonology may constitute a separate problem in Finnish SLI.
