The MacArthur-Bates Communicative Development Inventory was administered monthly from 8 to 14 months and at 18 and 24 months to caregivers of 14 HR infants diagnosed with ASD (HR-ASD), 27 HR infants with language delay (HR-LD), 51 HR infants with no diagnosis (HR-ND), and 28 LR infants. Few differences were obtained between LR and HR-ND infants, but HR-LD and HR-ASD groups differed in initial skill levels and growth patterns. While HR-LD infants grew at rates comparable to LR and HR-ND infants, growth was attenuated in the HR-ASD group, with trajectories progressively diverging from all other groups.

Object exploration at 6 and 9 months in infants with and without risk for autism / Erin A. KOTERBA in Autism, 18-2 (February 2014)  

Public ISBD [article]  inAutism > 18-2 (February 2014) . - p.97-105 Titre : Object exploration at 6 and 9 months in infants with and without risk for autism Type de document : texte imprimé Auteurs : Erin A. KOTERBA, Auteur ; Nina B. LEEZENBAUM, Auteur ; Jana M. IVERSON, Auteur Article en page(s) : p.97-105 Langues : Anglais (eng) Mots-clés : autism spectrum disorder  motor development  object exploration Index. décimale : PER Périodiques Résumé : During the first year of life, infants spend substantial amounts of time exploring objects they encounter in their daily environments. Perceptuo-motor information gained through these experiences provides a foundation for later developmental advances in cognition and language. This study aims to examine developmental trajectories of visual, oral, and manual object exploration in infants with and without risk for autism spectrum disorder before the age of 1 year. A total of 31 infants, 15 of whom had an older sibling with autism and who were therefore at heightened risk for autism spectrum disorder, played with sounding and nonsounding rattles at 6 and 9 months of age. The results suggest that heightened-risk infants lag behind their low-risk peers in the exploration of objects. The findings are discussed in terms of how delays in object exploration in infancy may have cascading effects in other domains.
