There is a documented need for appropriate language assessment measures for Spanish-English bilingual school-age children in the United States. The Bilingual English Spanish Assessment- Middle Extension (BESA-ME), the Test of Narrative Language (TNL), and the Test of Narrative Language- Spanish experimental version (Spanish TNL) were administered to 129 children ranging in age from 7;0 to 8;11. Convergence between the measures was examined. The results indicated a strong correlation between measures, as well as significant correlation between each measure and children’s ability level (i.e. classification as typically developing or with language impairment). These results present the BESA-ME and the TNL in Spanish and English as promising tools to assess language impairment in a population that traditionally has been a challenge to evaluate. / text

Variability inherently present between multiple talkers can prove beneficial in the context of learning. However, the performance during learning paradigms by children with specific language impairment (SLI) remains below typically developing peers, even when multiple talkers are used. Preschool children with typically developing language (n = 17) and SLI (n = 17) participated in a talker discrimination task. Five different pairings of talkers (same male, different males, same female, different females, male + female) were used to present 50 spoken words. Children with SLI were significantly poorer in discriminating same and different male speakers compared to their typical peers. The present findings demonstrate that preschool children with SLI can experience difficulty distinguishing between talkers. Poor sensitivity to variation in talkers may contribute to poor learning in SLI for contexts where multiple talker input should benefit the learner.

The procedural deficit hypothesis (PDH) posits that a range of language, cognitive and motor impairments associated with specific language impairment (SLI) and developmental dyslexia (DD) may be explained by an underlying domain-general dysfunction of the procedural memory system. In contrast, declarative memory is hypothesized to remain intact and to play a compensatory role in the two disorders. The studies in the present thesis were designed to test this hypothesis. Study I examined non-language procedural memory, specifically implicit sequence learning, in children with SLI. It was shown that children with poor performance on tests of grammar were impaired at consolidation of procedural memory compared to children with normal grammar. These findings support the PDH and are line with previous studies suggesting a link between grammar processing and procedural memory. In Study II, the same implicit sequence learning paradigm was used to test procedural memory in children with DD. The DD group showed a learning profile that was similar to that of children with SLI in Study I, with a significant impairment emerging late in learning, after extended practice and including an overnight interval. Further analyses suggested that the DD impairment may not be related to overnight consolidation but to the effects of further practice beyond the initial practice session. In contrast to the predictions of the PDH, the sequence learning deficit was unrelated to phonological processing skills as assessed with a nonword repetition task. Study III examined declarative memory in DD. The performance of the DD group was found to be not only intact, but even enhanced, compared to that of the control children. The results encourage further studies on the potential of declarative memory to compensate for the reading problems in DD. In sum, the results lend partial support for the PDH and suggest further refinements to the theory. Collectively, the studies emphasize the importance of going beyond a narrow focus on language learning and memory functions in the characterization of the two disorders. Such a broader cognitive, motor and language approach may inform the development of future clinical and pedagogical assessment and intervention practices for SLI and DD.

Rationale. Definition of complex behavioral disorders is generally phenomenological in nature and guided by pragmatic, rather than genetic, concerns. Consequently, important aspect of genetic analysis is the search for novel phenotypic definitions from the familial/genetic perspective. SLI study 1. SLI denotes an inability to acquire normal language in the absence of peripheral hearing impairment, neurological disorder, and mental retardation. Sibling resemblance for several theoretically derived specific components of the SLI phenotype was examined in families of SLI children. In 38 sib-pairs from 10 French-speaking pedigrees, Verb Tense Morphology sub-tests (Real and Non-real Words) showed nonparametric correlations of 0.39 and 0.35, respectively (p < 0.05, 2-tailed). In a densely affected Anglophone pedigree, 41 sib-pair showed familial resemblance with respect to Derivational Morphology (r = 0.52, p < 0.01). SLI study 2. Family history study in 27 families examined the relationship between attention deficit/hyperactivity in SLI children and familial risk of speech/language disorders. Higher odds of speech/language disorders were observed in first-degree relatives of 13 SLI children who also had a medical record of attention deficit/hyperactivity (15/27 vs. 4/46, p = 0.001). Alcoholism study 1. Latent class analysis (LCA) including gender and 15 antisocial behaviors (>15yr) was performed in 236 broadly ascertained alcohol-dependent subjects (121 males, 115 females). Evidence for 3 qualitative behavioral classes was obtained: Socially Adjusted Adults, SAA; Antisocial Non-Aggressive Adults, ANAA; and Antisocial Aggressive Adults, AAA. In both, genders, the AAA class had the earliest age of onset for alcohol dependence (p = 0.001), more alcoholic first-degree relatives and more of other psychopathology. In females, the ANAA class was intermediate. In the ANAA males, socially adjusted childhood behavior differentiated the late onset from the intermediate ons

On évoque souvent des difficultés à interagir socialement chez les enfants ayant une dysphasie. Ces difficultés sont généralement attribuées aux troubles du langage, mais elles pourraient aussi provenir d’un problème à décoder les émotions des autres. Le but de la présente recherche est d’explorer cette voie chez les enfants dysphasiques de 9 à 12 ans. Différents stimuli émotionnels leur ont été présentés sous forme de vidéos ainsi qu’à des enfants d’un groupe contrôle selon cinq conditions : parole non filtrée, parole filtrée, visage dynamique, visage dynamique accompagné de la parole non filtrée, et visage dynamique avec parole filtrée. Les enfants dysphasiques et les enfants du groupe contrôle ne se comportent pas différemment de manière significative en fonction des émotions présentées et des conditions testées. Par contre, un sous-groupe d’enfants ayant une dysphasie mixte commet significativement plus d’erreurs pour l’ensemble de la tâche que le sous-groupe d’enfants sans dysphasie de même âge chronologique. En fait une part seulement des enfants dysphasiques mixtes ont des scores plus faibles. Ces mêmes enfants présentent un QI non verbal faible tandis que leur compréhension du langage est équivalente à celle de leur sous-groupe (enfants dysphasiques mixtes). Malgré ces différences significatives, les scores des enfants dysphasiques mixtes restent relativement élevés et les difficultés observées sont subtiles. Sur le plan clinique, les praticiens (orthophonistes, psychologues, éducateur) devront systématiser l’évaluation des habiletés de décodage des émotions chez l’enfant dysphasique dont les difficultés ne sont pas forcément évidentes dans la vie quotidienne. La recherche devra développer un outil de dépistage sensible aux troubles de décodage émotionnel et des stratégies thérapeutiques adaptées. / Children with Specific Language Impairment (SLI) can have social problems that are often explained by their language disorders. However, the ability to identify other people’s emotions could be caused by their emotion processing difficulties. We explore this question in children with SLI aged 9 to 12 years old. Children with and without SLI were tested on five emotional stimuli presented in dynamic video and audio format: unfiltered speech, filtered speech, facial expressions, facial expressions with unfiltered speech, and facial expressions with filtered speech. The children with impaired language do not differ significantly from the unimpaired children across all modalities and emotions. However, a subgroup of SLI children with mixed (expressive-receptive) delay commits more errors on the task than their age-matched peers. In fact only a subgroup of these children shows lower scores. These same children also show low IQ scores but language comprehension as good as their subgroup. Despite these significant differences the mixed SLI group’s scores are quite high, showing that deficits are subtle. Clinical implications of this study militate for a systematization of the evaluation by health practitioners of these abilities in children with SLI who might not show obvious signs of deficits in this domain in their everyday activities. Research should pursue the development of a sensitive evaluation tool to identify emotional decoding difficulties and should evaluate therapeutic strategies adapted to this population.
