In this study, we first asked participants to describe closely related individuals such as parents and close friends with 10 positive and 10 negative characteristics. We then used standard natural language processing methods to digitize and visualize these descriptions. The complex patterns of these descriptive sentences exhibited a difference in semantic space between individuals with ASD and control participants. Machine learning algorithms were able to automatically detect and discriminate between these two groups. Furthermore, we showed that these descriptive sentences from adults with ASD exhibited fewer connections as defined by word–word co-occurrences in descriptions, and these connections in words formed a less “small-world” like network.

The Role of Adaptive Behavior in Autism Spectrum Disorders: Implications for Functional Outcome / Stephen M. KANNE in Journal of Autism and Developmental Disorders, 41-8 (August 2011)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 41-8 (August 2011) . - p.1007-1018 Titre : The Role of Adaptive Behavior in Autism Spectrum Disorders: Implications for Functional Outcome Type de document : Texte imprimé et/ou numérique Auteurs : Stephen M. KANNE, Auteur ; Andrew J. GERBER, Auteur ; Linda M. QUIRMBACH, Auteur ; Sara S. SPARROW, Auteur ; Domenic V. CICCHETTI, Auteur ; Celine A. SAULNIER, Auteur Année de publication : 2011 Article en page(s) : p.1007-1018 Langues : Anglais (eng) Mots-clés : Autism  Autism spectrum disorder  Adaptive functioning  Vineland Index. décimale : PER Périodiques Résumé : The relationship between adaptive functioning and autism symptomatology was examined in 1,089 verbal youths with ASD examining results on Vineland-II, IQ, and measures of ASD severity. Strong positive relationships were found between Vineland subscales and IQ. Vineland Composite was negatively associated with age. IQ accounted a significant amount of the variance in overall adaptive skills (55%) beyond age and ASD severity. Individuals with ASD demonstrated significant adaptive deficits and negligible associations were found between the level of autism symptomatology and adaptive behavior. The results indicate that IQ is a strong predictor of adaptive behavior, the gap between IQ and adaptive impairments decreases in lower functioning individuals with ASD, and older individuals have a greater gap between IQ and adaptive skills.

Using the Circumplex Model of Affect to Study Valence and Arousal Ratings of Emotional Faces by Children and Adults with Autism Spectrum Disorders / Angela TSENG in Journal of Autism and Developmental Disorders, 44-6 (June 2014)

PETERSON, Auteur Article en page(s) : p.1332-1346 Langues : Anglais (eng) Mots-clés : Circumplex model of affect  Valence  Arousal  Autism spectrum disorders  Facial emotion Index. décimale : PER Périodiques Résumé : The Affective Circumplex Model holds that emotions can be described as linear combinations of two underlying, independent neurophysiological systems (arousal, valence). Given research suggesting individuals with autism spectrum disorders (ASD) have difficulty processing emotions, we used the circumplex model to compare how individuals with ASD and typically-developing (TD) individuals respond to facial emotions. Participants (51 ASD, 80 TD) rated facial expressions along arousal and valence dimensions; we fitted closed, smooth, 2-dimensional curves to their ratings to examine overall circumplex contours. We modeled individual and group influences on parameters describing curve contours to identify differences in dimensional effects across groups. Significant main effects of diagnosis indicated the ASD-group’s ratings were constricted for the entire circumplex, suggesting range constriction across all emotions. Findings did not change when covarying for overall intelligence.
