The present study investigated the concurrent relations among expressive language and a set of empirically-selected social communication variables-joint attention, imitation, and play-in a unique sample of 37 minimally verbal (MV) children and adolescents with ASD. Results revealed that imitation and play were significantly correlated with expressive language, even when controlling for non-verbal IQ, but joint attention was not. Imitation was the only predictor variable to reach significance within the regression model. Findings demonstrate that predictors of expressive language vary for subpopulations of the autism spectrum, and have broader implications for intervention design for older, MV individuals with ASD.

Do minimally verbal and verbally fluent individuals with autism spectrum disorder differ in their viewing patterns of dynamic social scenes? / D. PLESA SKWERER in Autism, 23-8 (November 2019)  

Public ISBD [article]  inAutism > 23-8 (November 2019) . - p.2131-2144 Titre : Do minimally verbal and verbally fluent individuals with autism spectrum disorder differ in their viewing patterns of dynamic social scenes? Type de document : Texte imprimé et/ou numérique Auteurs : D. PLESA SKWERER, Auteur ; Brianna BRUKILACCHIO, Auteur ; A. CHU, Auteur ; B. EGGLESTON, Auteur ; S. MEYER, Auteur ; Helen TAGER-FLUSBERG, Auteur Article en page(s) : p.2131-2144 Langues : Anglais (eng) Mots-clés : dynamic scene  eye tracking  minimally verbal autism spectrum disorder  visual social attention Index. décimale : PER Périodiques Résumé : Attending preferentially to social information in the environment is important in developing socio-communicative skills and language. Research using eye tracking to explore how individuals with autism spectrum disorder deploy visual attention has increased exponentially in the past decade; however, studies have typically not included minimally verbal participants. In this study, we compared 37 minimally verbal children and adolescents with autism spectrum disorder with 34 age-matched verbally fluent individuals with autism spectrum disorder in how they viewed a brief video in which a young woman, surrounded by interesting objects, engages the viewer, and later reacts with expected or unexpected gaze-shifts toward the objects. While both groups spent comparable amounts of time looking at different parts of the scene and looked longer at the person than at the objects, the minimally verbal autism spectrum disorder group spent significantly less time looking at the person's face during the episodes where gaze following-a precursor of joint attention-was critical for interpreting her behavior. Proportional looking-time toward key areas of interest in some episodes correlated with receptive language measures. These findings underscore the connections between social attention and the development of communicative abilities in autism spectrum disorder.

How effective is LENA in detecting speech vocalizations and language produced by children and adolescents with ASD in different contexts? / R. M. JONES in Autism Research, 12-4 (April 2019)  

Public ISBD [article]  inAutism Research > 12-4 (April 2019) . - p.628-635 Titre : How effective is LENA in detecting speech vocalizations and language produced by children and adolescents with ASD in different contexts?

Its utility in children 5 years of age and older is not yet known. The present study used acoustic data from two samples of children with autism spectrum disorders (ASD) to evaluate the reliability of LENA automated analyses for detecting speech utterances in older, school age children, and adolescents with ASD, in clinic and home environments. Participants between 5 and 18 years old who were minimally verbal (study 1) or had a range of verbal abilities (study 2) completed standardized assessments in the clinic (study 1 and 2) and in the home (study 2) while speech was recorded from a LENA device. We compared LENA segment labels with manual ground truth coding by human transcribers using two different methods. We found that the automated LENA algorithms were not successful (<50% reliable) in detecting vocalizations from older children and adolescents with ASD, and that the proportion of speaker misclassifications by the automated system increased significantly with the target-child's age. The findings in children and adolescents with ASD suggest possibly misleading results when expanding the use of LENA beyond the age ranges for which it was developed and highlight the need to develop novel automated methods that are more appropriate for older children. Autism Research 2019, 12: 628-635. (c) 2019 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: Current commercially available speech detection algorithms (LENA system) were previously validated in toddlers and children up to 48 months of age, and it is not known whether they are reliable in older children and adolescents. Our data suggest that LENA does not adequately capture speech in school age children and adolescents with autism and highlights the need to develop new automated methods for older children.

A multimeasure approach to investigating affective appraisal of social information in Williams syndrome / D. PLESA SKWERER in Journal of Neurodevelopmental Disorders, 3-4 (December 2011)  

Public ISBD [article]  inJournal of Neurodevelopmental Disorders > 3-4 (December 2011) . - p.325-34 Titre : A multimeasure approach to investigating affective appraisal of social information in Williams syndrome Type de document : Texte imprimé et/ou numérique Auteurs : D.

FINE, Auteur ; Helen TAGER-FLUSBERG, Auteur Article en page(s) : p.325-34 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : People with Williams syndrome (WS) have been consistently described as showing heightened sociability, gregariousness, and interest in people, in conjunction with an uneven cognitive profile and mild to moderate intellectual or learning disability. To explore the mechanisms underlying this unusual social-behavioral phenotype, we investigated whether individuals with WS show an atypical appraisal style and autonomic responsiveness to emotionally laden images with social or nonsocial content. Adolescents and adults with WS were compared to chronological age-matched and nonverbal mental age-matched groups in their responses to positive and negative images with or without social content, using measures of self-selected viewing time (SSVT), autonomic arousal reflected in pupil dilation measures, and likeability ratings. The participants with WS looked significantly longer at the social images compared to images without social content and had reduced arousal to the negative social images compared to the control groups. In contrast to the comparison groups, the explicit ratings of likeability in the WS group did not correlate with their SSVT; instead, they reflected an appraisal style of more extreme ratings. This distinctive pattern of viewing interest, likeability ratings, and autonomic arousal to images with social content in the WS group suggests that their heightened social drive may be related to atypical functioning of reward-related brain systems reflected in SSVT and autonomic reactivity measures, but not in explicit ratings.
