Using the Language Environment Analysis (LENA) system in preschool classrooms with children with autism spectrum disorders / Jessica R. DYKSTRA in Autism, 17-5 (September 2013)
[article]
Titre : Using the Language Environment Analysis (LENA) system in preschool classrooms with children with autism spectrum disorders Type de document : Texte imprimé et/ou numérique Auteurs : Jessica R. DYKSTRA, Auteur ; Maura SABATOS-DEVITO, Auteur ; Dwight W. IRVIN, Auteur ; Brian A. BOYD, Auteur ; Kara HUME, Auteur ; Samuel L ODOM, Auteur Article en page(s) : p.582-594 Langues : Anglais (eng) Mots-clés : autism spectrum disorders preschool language natural environment LENA system Index. décimale : PER Périodiques Résumé : This study describes the language environment of preschool programs serving children with autism spectrum disorders (ASDs) and examines relationships between child characteristics and an automated measure of adult and child language in the classroom. The Language Environment Analysis (LENA) system was used with 40 children with ASD to collect data on adult and child language. Standardized assessments were administered to obtain language, cognitive, and autism severity scores for participants. With a mean of over 5 hours of recording across two days several months apart, there was a mean of 3.6 child vocalizations per minute, 1.0 conversational turns (in which either the adult or child respond to the other within 5 seconds) per minute, and 29.2 adult words per minute. Two of the three LENA variables were significantly correlated with language age-equivalents. Cognitive age-equivalents were also significantly correlated with two LENA variables. Autism Diagnostic Observation Schedule severity scores and LENA variables were not significantly correlated. Implications for using the LENA system with children with ASD in the school environment are discussed.

Titre : Child and classroom characteristics associated with the adult language provided to preschoolers with autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Dwight W. IRVIN, Auteur ; Kara HUME, Auteur ; Brian A. BOYD, Auteur ; Matthew T. MCBEE, Auteur ; Samuel L ODOM, Auteur Année de publication : 2013 Article en page(s) : p.947-955 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Preschool Adult language Natural environment LENA system Index. décimale : PER Périodiques Résumé : Abstract The aim of this study was to examine associations between the automated Language ENvironment Analysis (LENA) system adult word count (AWC) variable and characteristics of classrooms (e.g., teacher burnout) and preschoolers with autism spectrum disorder (ASD) (e.g., autism severity). The AWC samples from 67 preschoolers with ASD were collected during typical morning classroom routines (e.g., center time). Results indicated that AWC was positively associated with children's cognitive ability and negatively associated teacher burnout and adult to student with ASD ratio. Lower adult to children with ASD ratio (i.e., fewer adults relative to students with ASD) resulted in preschoolers receiving less adult language. Additional factors thought to be related to child and classroom characteristics affecting the adult language directed at children with ASD are discussed.
