Longitudinal development of language and fine motor skills is correlated, but not coupled, in a childhood atypical cohort / Marie K. DESERNO in Autism, 27-1 (January 2023)

Titre : Longitudinal development of language and fine motor skills is correlated, but not coupled, in a childhood atypical cohort Type de document : Texte imprimé et/ou numérique Auteurs : Marie K. DESERNO, Auteur ; Delia FUHRMANN, Auteur ; Sander BEGEER, Auteur ; Denny BORSBOOM, Auteur ; Hilde M. GEURTS, Auteur ; Rogier A. KIEVIT, Auteur Article en page(s) : p.133-144 Langues : Anglais (eng) Mots-clés : language development longitudinal cognitive dynamics mutualistic coupling structural equation modeling Index. décimale : PER Périodiques Résumé : Autism is often associated with early developmental delays in language and motor skills. However, little is known about the complex dynamic processes that drive the co-development of such early difficulties. The aim of the present study was to model the parallel growth of language and motor skills in a cohort of infants and to explore differences between infants with typical development and those with atypical development. Receptive and expressive language and fine motor skills were repeatedly assessed in a group of 239 infants (7 months at t1 and 36 months at t4) from the British Autism Study of Infant Siblings sample. Latent Growth Curve Analysis was applied to investigate the mutualistic coupling of longitudinal changes in these domains. Our results showed highly correlated slopes but we did not find an association between baseline scores in one domain and rates of change in the other (i.e. coupling). In the later diagnosed group, we found that scores at baseline and rates of change were more variable. Lay abstract More and more members of the autistic community and the research field are moving away from the idea that there will be a single biological or cognitive explanation for autistic characteristics. However, little is known about the complex dynamic processes that could explain why early difficulties in the language and motor domain often go hand-in-hand. We here study how language and motor skills develop simultaneously in the British Autism Study of Infant Siblings cohort of infants, and compare the way they are linked between children with and without developmental delays. Our results suggest that improvements in one domain go hand-in-hand with improvements in the other in both groups and show no compelling evidence for group differences in how motor skills relate to language and vice versa. We did observe a larger diversity in motor and language skills at 6 months, and because we found the motor and language development to be tightly linked, this suggests that even very small early impairments can result in larger developmental delays in later childhood. Greater variability at baseline, combined with very strong correlations between the slopes, suggests that dynamic processes may amplify small differences between individuals at 6months to result into large individual differences in autism symptomatology at 36 months.
