The Mind

ABSTRACTThe properties of reflexives vary across adult languages with respect to (i) the domain in which a reflexive may be bound and (ii) the syntactic positions an appropriate antecedent may occupy. These two issues have been approached in GB theory in various ways, each with specific implications for acquisition. In this paper we examine these implications by testing normal and Specific Language Impaired (SLI) children for evidence of the binding domain and orientation properties of their grammars. The investigation reveals that, contrary to most previous claims, normal children acquiring English pass through a long-distance binding stage. SLI children, however, do not display this pattern, tending instead to behave like very young normal children in requiring the nearest available NP to be the antecedent. We argue that this constitutes an early binding stage not previously identified. Finally, we interpret our findings in terms of a conception of acquisition dubbed the ‘competing grammars’ model, according to which competing incompatible grammars may coexist in the mind of the learner.

Similar Tendency

This study examined the characteristics of early lexical acquisition in children with specific language impairment. Sixteen unfamiliar words and referents were exposed across 10 sessions to language-impaired and normal children matched for level of linguistic development. Posttesting revealed similar comprehension-production gaps in the two groups of children. In addition, both groups showed greater comprehension and production of words referring to objects than words referring to actions. However, the language-impaired children's object word bias was not as marked as that of the normal children. For both groups, words containing initial consonants within the children's production repertoires were more likely to be acquired in production than words containing consonants absent from the children's phonologies. A similar tendency was not seen for comprehension.

The Mind

This paper provides a further investigation into the linguistic abilities of a subgroup of 12 Grammatical specific language impaired (SLI) children (aged 10;2 to 13;11). The study investigates the use of referential expressions (e.g. pronouns) in a narrative discourse, and provides insight into the underlying nature of Grammatical SLI, thereby contributing to the modularity debate. Previous investigations indicate that Grammatical SLI children have a deficit with dependent structural relationships, i.e. a Representational Deficit for Dependent Relationships (RDDR). Grammatical SLI children's RDDR appears to be a modular language deficit. To test this claim, linguistic representations of dependent structural relationships which are not part of the modular language system are investigated using a narrative discourse based on the picture book Frog where are you? The SLI children's pattern of referential expressions was compared with 36 language ability controls (aged 6;4 to 9;8). The findings indicated that the Grammatical SLI children have relatively mature linguistic development in the use of referential expressions to produce a cohesive, structured narrative discourse. The view of the organisation of the mind in which a modular language system can be differentially impaired from aspects of language which rely on the central system can most easily account for the data. Thus, the data support the hypothesized modular nature of Grammatical SLI children's underlying linguistic deficit. The implications of the findings for language acquisition are discussed.

Vineland Adaptive Behavior

ABSTRACTThis study examined mothers' accuracy in predicting the responses their children gave and the scores they achieved on two standardized vocabulary tests. Three groups of 16 mothers and their preschool children (specific language-impaired; age-matched, language-normal; and younger, language-matched, language-normal) completed the Peabody Picture Vocabulary Test-Revised, Expressive One-Word Picture Vocabulary Test-Revised, and Vineland Adaptive Behavior Scales. Mothers overestimated their children's standardized receptive and expressive scores, with the exception that the mothers' estimates of the receptive vocabulary scores for language-impaired children did not differ from the actual test scores. Mothers of age-matched normals were best able to predict the labels their children used to name various pictured items. However, the overall estimates by mothers of language-impaired children were more accurate than those by mothers of language-normal children.

Impaired Children

The purpose of the present study was to determine whether the results of a language-teaching procedure could be used to identify specific language-impaired children in a group of bilingual children with limited English proficiency (LEP). An invented morpheme was taught to two groups of LEP children who had been previously identified as normal and specific language-impaired. The language-impaired group learned the morpheme at a slower rate than the normal children, thus allowing the two groups to be differentiated. The approach promises to circumvent many of the obstacles that impede current practices for identifying language impairment in the LEP population.

Unfamiliar Object

ABSTRACTSpecifically-language-impaired children and younger normal children matched for expressive language were presented with unfamiliar object names and referents across five experimental sessions. The objects differed in the degree to which they were associated with actions, and only certain of the object exemplars were named during presentation. Comprehension testing revealed that the specifically-language-impaired children acquired a greater number of object concepts presented in a no-action condition than the normal children. However, their extension of the names to new exemplars was more restricted and less differentiated. Several possible accounts of these findings are evaluated.

In the present study, we further examined (see Kamhi & Catts, 1986) the phonological processing abilities of language-impaired (LI) and reading-impaired (RI) children. We also evaluated these children's ability to process spatial information. Subjects were 10 LI, 10 RI, and 10 normal children between the ages of 6:8 and 8:10 years. Each subject was administered eight tasks: four word repetition tasks (monosyllabic, monosyllabic presented in noise, three-item, and multisyllabic), rapid naming, syllable segmentation, paper folding, and form completion. The normal children performed significantly better than both the LI and RI children on all but two tasks: syllable segmentation and repeating words presented in noise. The LI and RI children performed comparably on every task with the exception of the multisyllabic word repetition task. These findings were consistent with those from our previous study (Kamhi & Catts, 1986). The similarities and differences between LI and RI children are discussed.

Novel Words

This investigation examined the influence of unsolicited lexical imitation on the comprehension and on the production of novel words by language-impaired children. Subjects were 13 children (2:8–3:1) exhibiting specific language impairment who were presented with 16 unfamiliar words referring to unfamiliar objects or actions over 10 experimental sessions. Unsolicited imitations appeared to facilitate subsequent production of these words on a posttest. This effect was greatest when these words were also produced spontaneously prior to the posttest. Words that were produced imitatively and spontaneously also appeared more frequently in spontaneous usage than words that were only produced spontaneously. No relationship between such imitations and comprehension was observed. These findings suggest that unsolicited imitations benefit children's lexical acquisition primarily by providing them with additional opportunities to produce words that are in the process of being established in their expressive lexicons.

This study examined the comprehension of four pairs of deictic terms in a group of language impaired children and compared their interpretation of these terms with those of non-language impaired children of the same age range. Each group was comprised of ten subjects within the age range of 9,6 to 10,6 years. Two tasks were administered, one to assess the comprehension of the terms here, there, this, and that and the other to assess the comprehension of the terms, come, go, bring and take. The results showed that while the non-language impaired subjects comprehended the full deictic contrast between the pairs of terms tested, the language impaired group did not. A qualitative analysis of the data revealed that the language impaired subjects appeared to follow the same developmental sequence as normal children in their acquisition of these terms and responded by using the same strategies that younger non-language impaired children use at equivalent stages of development. Furthermore, the language impaired subjects appeared to comprehend the deictic terms in a predictable order based on their relative semantic complexity.

Perceptual Abilities

A battery of nonverbal perceptual and memory tests were given to 35 language-impaired (LI) and 38 control subjects. Three modalities of tests were given: auditory, visual, and cross-modal (auditory and visual). The purpose was to reexamine some nonverbal perceptual and memory abilities of LI children as a function of age and modality of stimulation. Results failed to replicate previous findings of a temporal processing deficit that is specific to the auditory modality in LI children. The LI group made significantly more errors than did controls regardless of modality of stimulation when 2-item sequences were presented rapidly, or when more than two stimuli were presented in series. However, further analyses resolved this apparent conflict between the present and earlier studies by demonstrating that age is an important variable underlying modality specificity of perceptual performance in LI children. Whereas younger LI children were equally impaired when responding to stimuli presented rapidly to the auditory and visual modality, older LI subjects made nearly twice as many errors responding to rapidly presented auditory rather than visual stimuli. This developmental difference did not occur for the control group.

Aspects of the discourse of 5 language-impaired children and 5 children with no language impairment, aged approximately 9 years, were compared. A film and a story sequence were utilised to elicit narratives on which, measures of cohesion, tense and pronouns were appraised. Measures of cohesion refer  to the ability to indicate appropriately the relations of meaning with regard to situational context. Measures of tense include aspects of tense range and tense continuity. Measures of  pronouns refer  to the anaphoric use of  pronouns with non-ambiguous referents.  The group of language-impaired children was found  to be significantly poorer on measures of  cohesion and pronominal usage than the normal children, whereas a significant difference between the two groups was not revealed on measures of tense. Possible factors  accounting for  these findings  were discussed and implications for the diagnosis and therapy of the older language-impaired child were considered.
