Declarative Learning

Language Impairment (LI) is a developmental disorder that mainly manifests impaired language learning and processing. Evidence, largely from English-speaking population studies, has shown that children with LI compared to typically developing (TD) children have low scores in sequential learning tasks but similar performance in declarative learning tasks. According to the declarative/procedural model, LI children compensate for their deficiency in syntactic skills (i.e., deficits in the procedural memory system) by using the declarative memory system (indispensable for vocabulary acquisition). Although there are specific deficits in children with LI depending on the language they speak, it is assumed that this model can explain the shortcomings of such pathology regardless of the language spoken. In the current study, we compared the performance of fifteen school-aged Mexican Spanish-speaking children with LI and twenty TD children during sequential and declarative learning tasks and then analyzed the relationship between their performance in these tasks and their abilities in syntax and semantics. Children with LI displayed lower scores than normal children in the sequential learning task, but no differences were found in declarative learning performance with verbal or visual stimuli. No significant correlations were observed in children with LI between their performance in sequential learning and their abilities in semantics and no significant correlations were observed in TD children between their performance in sequential learning and their abilities in syntax. In contrast, for children with LI, a significant correlation between their performance in declarative learning and their abilities in semantics was observed and for the group of TD children a significant correlation between their performance in declarative learning and their abilities in syntax was observed. This study shows that Spanish-speaking children with LI display a pattern of learning impairment that supports the declarative/procedural model hypothesis. However, they display poor verbal declarative learning skills, probably due to low verbal working memory capacity.

Word Forms

The production of regular and irregular past tense forms was investigated among the members of an English-speaking family with a hereditary disorder of language. Unlike the control subjects, the family members affected by the disorder failed to generate overregularizations (e.g., digged) or novel regular forms (plammed, crived), whereas they did produce novel irregularizations (crive–crove). They showed word frequency effects for regular past tense forms (looked) and had trouble producing regulars and irregulars (looked, dug). This pattern cannot be easily explained by deficits of articulation or of perceptual processing, by previous simulations of impairments to a single-mechanism system, or by the extended optional infinitive hypothesis. We argue that the pattern is consistent with a three-level explanation. First, we posit a grammatical deficit of rules or morphological paradigms. This may be caused by a dysfunction of a frontal/basal-ganglia “procedural memory” system previously implicated in the implicit learning and use of motor and cognitive skills. Second, in contexts requiring inflection in the normal adult grammar, the affected subjects appear to retrieve word forms as a function of their accessibility and conceptual appropriateness (“conceptual selection”). Their acquisition and use of these word forms may rely on a “declarative memory” system previously implicated in the explicit learning and use of facts and events. Third, a compensatory strategy may be at work. Some family members may have explicitly learned a strategy of adding suffix-like endings to forms retrieved by conceptual selection. The morphological errors of young normal children appear to be similar to those of the affected family members, who may have been left stranded with conceptual selection by a specific developmental arrest. The same underlying deficit may also explain the impaired subjects' difficulties with derivational morphology.

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.

Semantic Distinction

Purpose The purpose of this study was to delineate differences between children with specific language impairment (SLI), typical age–matched (TAM) children, and typical younger (TY) children in learning and mastering an undisclosed artificial morphological rule (AMR) through exposure and usage. Method Twenty-six participants (eight 10-year-old children with SLI, 8 TAM children, and ten 8-year-old TY children) were trained to master an AMR across multiple training sessions. The AMR required a phonological transformation of verbs depending on a semantic distinction: whether the preceding noun was animate or inanimate. All participants practiced the application of the AMR to repeated and new (generalization) items, via judgment and production tasks. Results The children with SLI derived significantly less benefit from practice than their peers in learning most aspects of the AMR, even exhibiting smaller gains compared to the TY group in some aspects. Children with SLI benefited less than TAM and even TY children from training to judge and produce repeated items of the AMR. Nevertheless, despite a significant disadvantage in baseline performance, the rate at which they mastered the task-specific phonological regularities was as robust as that of their peers. On the other hand, like 8-year-olds, only half of the SLI group succeeded in uncovering the nature of the AMR and, consequently, in generalizing it to new items. Conclusions Children with SLI were able to learn language aspects that rely on implicit, procedural learning, but experienced difficulties in learning aspects that relied on the explicit uncovering of the semantic principle of the AMR. The results suggest that some of the difficulties experienced by children with SLI when learning a complex language regularity cannot be accounted for by a broad, language-related, procedural memory disability. Rather, a deficit—perhaps a developmental delay in the ability to recruit and solve language problems and establish explicit knowledge regarding a language task—can better explain their difficulties in language learning.

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.

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.
