Intrinsic and Extrinsic Motivation for Stereotypic and Repetitive Behavior / Annette V. JOOSTEN in Journal of Autism and Developmental Disorders, 39-3 (March 2009)

JOOSTEN, Auteur ; Anita BUNDY, Auteur ; Stewart L. EINFELD, Auteur Année de publication : 2009 Article en page(s) : p.521-531 Langues : Anglais (eng) Mots-clés : Stereotypic Intrinsic Extrinsic Anxiety Rasch-analysis Index. décimale : PER Périodiques Résumé : This study provides evidence for intrinsic and extrinsic motivators for stereotypical and repetitive behavior in children with autism and intellectual disability and children with intellectual disability alone. We modified the Motivation Assessment Scale (MAS) (1988b); dividing it into intrinsic and extrinsic measures and adding items to assess anxiety as an intrinsic motivator. Rasch analysis of data from 279 MASs (74 children) revealed that the items formed two unidimensional scales. Anxiety was a more likely intrinsic motivator than sensory seeking for children with dual diagnoses; the reverse was true for children with intellectual disability only. Escape and gaining a tangible object were the most common extrinsic motivators for those with dual diagnoses and attention and escape for children with intellectual disability.

The Motivation of Stereotypic and Repetitive Behavior: Examination of Construct Validity of the Motivation Assessment Scale / Annette V. JOOSTEN in Journal of Autism and Developmental Disorders, 38-7 (August 2008)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 38-7 (August 2008) . - p.1341-1348 Titre : The Motivation of Stereotypic and Repetitive Behavior: Examination of Construct Validity of the Motivation Assessment Scale Type de document : Texte imprimé et/ou numérique Auteurs : Annette V. JOOSTEN, Auteur ; Anita BUNDY, Auteur Année de publication : 2008 Article en page(s) : p.1341-1348 Langues : Anglais (eng) Mots-clés : Motivation Stereotypic Repetitive Validity Rasch-analysis Index. décimale : PER Périodiques Résumé : Construct validity of the Motivation Assessment Scale (MAS) (Durand, Crimmins, The Motivation Assessment Scale 1988) was studied using Rasch analysis data from 67 children (246 MASs), with dual diagnosis of autism and intellectual disability or with intellectual disability only. Results failed to support the proposed unidimensional construct or the original 4-factor structure. Some motivators appear to form a unidimensional construct: “to gain attention”, “to gain a tangible object”, and “to escape”. There was evidence that sensory stimulation represents a different construct. Children with intellectual disability were more apt to be motivated by desire to gain a tangible item or attention. Children with the dual diagnoses were more apt to have sensory stimulation or escape from task demand as a motivator for stereotypic and repetitive behavior.

Visual search strategies during facial recognition in children with ASD / Matthew A. ALBRECHT in Research in Autism Spectrum Disorders, 8-5 (May 2014)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 8-5 (May 2014) . - p.559-569 Titre : Visual search strategies during facial recognition in children with ASD Type de document : Texte imprimé et/ou numérique Auteurs : Matthew A. ALBRECHT, Auteur ; Jonathan K. FOSTER, Auteur ; Annette V. JOOSTEN, Auteur ; Marita FALKMER, Auteur ; Julia S. Y. TANG, Auteur ; Denise LEUNG, Auteur ; Anna ORDQVIST, Auteur ; Torbjörn FALKMER, Auteur Article en page(s) : p.559-569 Mots-clés : Face recognition  Eye-tracking  Developmental  Visual search Index. décimale : PER Périodiques Résumé : Facial recognition is a complex skill necessary for successful human interpersonal and social interactions. Given that the most prevalent disorder of social interaction is autism spectrum disorder (ASD), a number of studies have investigated and found impaired facial recognition abilities in people with ASD. Further, this impairment may be critically involved in mediating the deficits in interpersonal and social interactions in people with ASD. We sought to address the question of whether face processing is impaired in children with ASD in the current study. While there were a number of differences in visual search behaviours between the 19 children with ASD and the 15 controls, this did not manifest in deficits in facial recognition accuracy. In addition, there were notable differences with respect to eye fixation behaviours and recognition accuracy in this study compared to the findings in a previous similar study conducted in adults with ASD. These differences suggest a performance enhancing developmental trajectory in facial processing in controls that may not be present in individuals with ASD.
