Body movement imitation and early language as predictors of later social communication and language outcomes: A longitudinal study / Andrea DOHMEN in Autism & Developmental Language Impairments, 1 (January-December 2016)  

Public ISBD [article]  inAutism & Developmental Language Impairments > 1 (January-December 2016) Titre : Body movement imitation and early language as predictors of later social communication and language outcomes: A longitudinal study Type de document : Texte imprimé et/ou numérique Auteurs : Andrea DOHMEN, Auteur ; Dorothy V. M. BISHOP, Auteur ; Shula CHIAT, Auteur ; Penny ROY, Auteur Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Background and aimsOver recent decades much research has focused on detecting predictors of different language trajectories in children with early language delay but there has been very little exploration of social communication trajectories in these children. We report a longitudinal study that investigated the predictive value and clinical significance of elicited body movement imitation and language for later social communication and language outcome in Late Talkers.MethodsParticipants were 29 German-speaking children who were identified with delayed onset and progression of language at two years and followed up at four years. Novel assessments of posture and gesture imitation were administered at Time 1, together with standardised language measures. All body movement imitation items involved self-other mappings, assumed to rely on sociocognitive capacities. At Time 2, children were assessed on standard language tests, together with parental reports of social communication.ResultsEarly language skills at Time 1 were significantly associated with later language outcome and body movement imitation skills at Time 1 with later social communication outcome. Logistic regression analyses revealed that body movement imitation as well as language at Time 1 added significantly to the prediction of language outcome at Time 2, whereas only body movement imitation made a significant contribution to the prediction of social communication outcome at Time 2.Conclusions and implicationsTheoretically, results highlight the need to account for the heterogeneity of different language and communication trajectories in children with early language delay and point to the importance of sociocognitive difficulties observed in some of these children. Clinically, this study demonstrated that body movement imitation measures have the potential to improve the identification of pre-schoolers who are at risk of later social communication and language problems.

Declarative capacity does not trade-off with procedural capacity in children with specific language impairment / Sengottuvel KUPPURAJ in Autism & Developmental Language Impairments, 1 (January-December 2016)  

Public ISBD [article]  inAutism & Developmental Language Impairments > 1 (January-December 2016) Titre : Declarative capacity does not trade-off with procedural capacity in children with specific language impairment Type de document : Texte imprimé et/ou numérique Auteurs : Sengottuvel KUPPURAJ, Auteur ; Prema RAO, Auteur ; Dorothy V. M. BISHOP, Auteur Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Background and aimsThe procedural deficit hypothesis attributes the language phenotype in children with specific language impairment to an impaired procedural and relatively intact declarative memory system. The declarative compensatory hypothesis is an extension of the procedural deficit hypothesis which claims that the declarative system in specific language impairment compensates for the procedural deficit. The present study?s aim was to examine the claims of the procedural deficit hypothesis and declarative compensatory hypothesis by examining these memory systems and relation between them in specific language impairment.MethodsParticipants were children aged 8?13 years, 30 with specific language impairment and 30 typically developing controls, who spoke Kannada (an agglutinating language of the Dravidian family). Procedural learning was assessed using a serial reaction time task. Declarative memory was assessed using two non-verbal tasks that differed at the level of encoding and retrieval: a recognition memory task after incidental encoding using real and novel object images and a recall task after intentional encoding using visual paired associates. Retrieval was examined after short (10?min) and long (60?min) delays after encoding on both declarative tasks.ResultsFindings confirmed that children with specific language impairment (SLI) have impaired procedural memory on a non-verbal serial reaction time task. On recognition memory task after incidental encoding though children with specific language impairment encoded less well, they recognized items as well as typically developing controls. Both the groups retrieved more at short compared to long intervals and retrieved real (verbalizable) objects better than novel objects. On visual paired associates (recall task with intentional encoding) children with specific language impairment retrieved less than typically developing children (even after controlling for non-verbal ability and age). Furthermore, across retrieval types of declarative tasks, although children with specific language impairment did less well than typically developing, their pattern of performance was comparable to typically developing children. Finally, the correlation between memory systems did not support a trade-off between memory systems in children with SLI as predicted by the compensatory wing of procedural deficit hypothesis.ConclusionsThe findings supported the major claim of the procedural deficit hypothesis ? a procedural learning deficit in specific language impairment and an intact declarative system, however, only if measured on task that was designed to be undemanding. Furthermore, there was no evidence for a trade-off between these systems.Implications and future directionsSome interventions with specific language impairment use explicit teaching of grammar, an approach that uses the declarative rather than the procedural system. Our findings cast doubt on whether this is likely to be the most effective strategy.

Conduct problems co-occur with hyperactivity in children with language impairment: A longitudinal study from childhood to adolescence / Andrew PICKLES in Autism & Developmental Language Impairments, 1 (January-December 2016)  

Public ISBD [article]  inAutism & Developmental Language Impairments > 1 (January-December 2016) Titre : Conduct problems co-occur with hyperactivity in children with language impairment: A longitudinal study from childhood to adolescence Type de document : Texte imprimé et/ou numérique Auteurs : Andrew PICKLES, Auteur ; Kevin DURKIN, Auteur ; Pearl L. H. MOK, Auteur ; Umar TOSEEB, Auteur ; Gina CONTI-RAMSDEN, Auteur Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : BackgroundLanguage impairment is a common developmental disorder which is frequently associated with externalising problems. In this study, we investigate for the first time, joint trajectories of conduct problems and hyperactivity in children with language impairment from childhood to adolescence. We determine patterns of co-occurrence of symptoms and identify specific risk and protective factors.MethodsWe develop a trajectory grouping method to examine simultaneously the conduct and hyperactivity problem scores of 164 children with language impairment at 7, 8, 11 and 16 years of age.ResultsWe identified five groups of children with distinct trajectories of symptoms. Three trajectory groups all had different conduct/hyperactivity problems: a persistent problems group (15%), an adolescent-onset group (24%) and a childhood-limited group (17%). There were two trajectory groups that did not show conduct problems.ConclusionsConduct problems always co-occurred with hyperactivity in children with language impairment regardless of differences in the onset of symptoms (childhood versus adolescence) or their persistence (persistent versus childhood limited). Reading difficulties were strongly associated with mixed conduct/hyperactivity problems that started early (childhood) and continued into adolescence (the persistent trajectory group). Prosocial behaviours were found to be protective against conduct problems.
