Titre : Adults with Autism Show Increased Sensitivity to Outcomes at Low Error Rates During Decision-Making Type de document : Texte imprimé et/ou numérique Auteurs : Arpi MINASSIAN, Auteur ; Alan J. LINCOLN, Auteur ; Martin PAULUS, Auteur ; William PERRY, Auteur Année de publication : 2007 Article en page(s) : p.1279-1288 Langues : Anglais (eng) Mots-clés : Autistic-disorder Decision-making Perseveration Executive-functioning Reinforcement Cognition Index. décimale : PER Périodiques Résumé : Decision-making is an important function that can be quantified using a two-choice prediction task. 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.

Titre : Attentional networks in children and adolescents with autism spectrum disorder Type de document : Texte imprimé et/ou numérique 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.En ligne : http://dx.doi.org/10.1111/j.1469-7610.2010.02257.x Permalink : https://www.cra-rhone-alpes.org/cid/opac_css/index.php?lvl=notice_display&id=110

GOLOMB, Auteur Année de publication : 2012 Article en page(s) : p.1120-1126 Langues : Anglais (eng) Mots-clés : Autism ASD Magnetic resonance Energetics Muscle Brain Awake Index. décimale : PER Périodiques Résumé : We piloted a suite of approaches aimed to facilitate a successful series of up to four brain and muscle 31Phosphorus-Magnetic Resonance Spectroscopy (31P-MRS) scans performed in one session in 12 awake, non-sedated subjects (ages 6–18), 6 with autism spectrum disorders (ASD) and 6 controls. 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.

LINCOLN, Auteur ; Laurie A. BRENNER, Auteur ; Ralph-Axel MULLER, Auteur ; Aurora I. RAMOS, Auteur ; Sandra P. MARSHALL, Auteur Année de publication : 2009 Article en page(s) : p.383-387 Langues : Anglais (eng) Mots-clés : Autism Reaction-time Visual-attention Visual-perception Eye-movement Eye-fixation Index. décimale : PER Périodiques Résumé : The present study examined fixation frequency and duration during an Embedded Figures Test (EFT) in an effort to better understand the attentional and perceptual processes by which individuals with autism spectrum disorder (ASD) achieve accelerated EFT performance. 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.

SEARCY, Auteur ; Ursula BELLUGI, Auteur Année de publication : 2007 Article en page(s) : p.513-522 Langues : Anglais (eng) Mots-clés : Williams-syndrome Emotion Affect Face-processing Visual-discrimination Index. décimale : PER Périodiques Résumé : We sought to clarify the nature of the face processing strength commonly observed in individuals with Williams syndrome (WS) by comparing the face recognition ability of persons with WS to that of persons with autism and to healthy controls under three conditions: Upright faces with neutral expressions, upright faces with varying affective expressions, and inverted faces with neutral expressions. No differences were observed under the upright/neutral expression condition. However, the WS group was more accurate than the autism group when discriminating upright faces with varying affective expressions, whereas the opposite pattern emerged when discriminating inverted faces. We interpret these differences as a reflection of the contrasting social features of the two syndromes.
