Adults with Autism Show Increased Sensitivity to Outcomes at Low Error Rates During Decision-Making / Arpi MINASSIAN in Journal of Autism and Developmental Disorders, 37-7 (August 2007)

Individuals with Autistic Disorder (AD) often show highly restricted and repetitive behavior that may interfere with adaptive decision-making. We assessed whether AD adults showed repetitive behavior on the choice task that was unaffected by changing task demands, by examining the influence of experimenter-determined error rates on decision-making. Sixteen AD adults and 14 typically developed subjects were administered a two-choice task using three error rate conditions. Although AD subjects showed occurrences of stereotyped responding, their decision-making behavior was strongly affected by changes in task demands, especially when they experienced frequent success. Thus, behavioral paradigms that provide frequent reinforcement may be helpful in modifying decision-making abilities in AD.

Attentional networks in children and adolescents with autism spectrum disorder / Brandon KEEHN in Journal of Child Psychology and Psychiatry, 51-11 (November 2010)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 51-11 (November 2010) . - p.1251-1259 Titre : Attentional networks in children and adolescents with autism spectrum disorder Type de document : texte imprimé Auteurs : Brandon KEEHN, Auteur ; Alan J. LINCOLN, Auteur ; Ralph-Axel MULLER, Auteur ; Jeanne TOWNSEND, Auteur Année de publication : 2010 Article en page(s) : p.1251-1259 Langues : Anglais (eng) Mots-clés : Autism reaction-time visual-attention alerting orienting executive-control Index. décimale : PER Périodiques Résumé : Background:  Individuals diagnosed with autism spectrum disorder (ASD) exhibit lifelong abnormalities in the adaptive allocation of visual attention. The ubiquitous nature of attentional impairments in ASD has led some authors to hypothesize that atypical attentional modulation may be a factor in the development of higher-level sociocommunicative deficits. Method:  Participants were 20 children with ASD and 20 age- and Nonverbal IQ-matched typically developing (TD) children. We used the Attention Network Test (ANT) to investigate the efficiency and independence of three discrete attentional networks: alerting, orienting, and executive control. Additionally, we sought to investigate the relationship between each attentional network and measures of sociocommunicative symptom severity in children with ASD. Results:  Results indicate that the orienting, but not alerting or executive control, networks may be impaired in children with ASD. In contrast to TD children, correlational analyses suggest that the alerting and executive control networks may not function as independently in children with ASD. Additionally, an association was found between the alerting network and social impairment and between the executive control network and IQ in children with ASD. Conclusions:  The results provide further evidence of an impairment in the visuospatial orienting network in ASD and suggest that there may be greater interdependence of alerting and executive control networks in ASD. Furthermore, decreased ability to efficiently modulate levels of alertness was related to increased sociocommunicative deficits, suggesting that domain-general attentional function may be associated with ASD symptomatology.

Brief Report: Approaches to 31P-MRS in Awake, Non-Sedated Children with and without Autism Spectrum Disorder / Laura C. ERICKSON in Journal of Autism and Developmental Disorders, 42-6 (June 2012)

We targeted advanced preparation, parental input, physical comfort, short scan protocols, allocation of extra time, and subject emotional support. 100% of subjects completed at least one brain scan and one leg muscle scan: 42 of 46 attempted scans were completed (91%), with failures dominated by exercise muscle scans (completed in 6/6 controls but 3/6 cases). One completed scan lacked usable data unrelated to subject/scan procedure (orthodonture affected a frontal brain scan). As a group, these methods provide a foundation for conduct and enhancement of future MR studies in pediatric subjects with ASD.

In particular, we aimed to elucidate differences in the patterns of eye-movement in ASD and typically developing (TD) children, thus providing evidence relevant to the competing theories of weak central coherence (WCC) and enhanced perceptual functioning. Consistent with prior EFT studies, we found accelerated response time (RT) in children with ASD. No group differences were seen for fixation frequency, but the ASD group made significantly shorter fixations compared to the TD group. Eye-movement results indicate that RT advantage in ASD is related to both WCC and enhanced perceptual functioning.

Efficacy of a computer-assisted cognitive-behavior therapy program for treating youth with anxiety and co-occurring autism spectrum disorder: Camp Cope-A-Lot / Felicia CRUZ PRYOR in Research in Autism Spectrum Disorders, 83 (May 2021)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 83 (May 2021) . - 101748 Titre : Efficacy of a computer-assisted cognitive-behavior therapy program for treating youth with anxiety and co-occurring autism spectrum disorder: Camp Cope-A-Lot Type de document : texte imprimé Auteurs : Felicia CRUZ PRYOR, Auteur ; Alan J.

Methods The computer-assisted cognitive behavior therapy (CBT) program for treating anxiety, Camp Cope-A-Lot (CCAL) was compared to control intervention, another computer-assisted program, The Social Express (TSE), that does not employ CBT nor is targeted for the treatment of anxiety. TSE is designed to improve social skills in youth with ASD. Participants had a principal anxiety disorder and a current diagnosis of ASD. Participants received 12-sessions of CCAL or 12-sessions of TSE. Outcome measures were obtained at intake, upon completion of the first intervention of the trial and upon completion of the second intervention of the trial. Results CCAL was efficacious for treating anxiety. Participants who completed CCAL demonstrated significant and clinical reductions in anxiety when compared to participants who completed TSE. Both interventions, CCAL and TSE, resulted in some limited improvement in social skills. Conclusions The current study showed that anxiety symptoms in youth with ASD and co-occurring anxiety disorders can benefit from computer-assisted CBT employing CCAL. This expands previous literature employing computer-assisted CBT interventions in youth, and more specifically, youth with ASD.
