Titre : Mimetic desire in autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Baudouin FORGEOT D'ARC, Auteur ; F. VINCKIER, Auteur ; M. LEBRETON, Auteur ; I. SOULIERES, Auteur ; Laurent MOTTRON, Auteur ; M. PESSIGLIONE, Auteur Article en page(s) : 45p. Langues : Anglais (eng) Mots-clés : Adolescent Adult Anhedonia Autism Spectrum Disorder/physiopathology/psychology Case-Control Studies Female Humans Imitative Behavior/physiology Judgment Male Motivation/physiology Psychological Tests Social Perception Autism Brain valuation system Mimetic desire Mirror neuron system Restricted interests Social cognition Social influence Social motivation Index. décimale : PER Périodiques Résumé : Mimetic desire (MD), the spontaneous propensity to pursue goals that others pursue, is a case of social influence that is believed to shape preferences. Autism spectrum disorder (ASD) is defined by both atypical interests and altered social interaction. We investigated whether MD is lower in adults with ASD compared to typically developed adults and whether MD correlates with social anhedonia and social judgment, two aspects of atypical social functioning in autism. Contrary to our hypotheses, MD was similarly present in both ASD and control groups. Anhedonia and social judgment differed between the ASD and control groups but did not correlate with MD. These results extend previous findings by suggesting that basic mechanisms of social influence are preserved in autism. The finding of intact MD in ASD stands against the intuitive idea that atypical interests stem from reduced social influence and indirectly favors the possibility that special interests might be selected for their intrinsic properties.

Titre : Brief Report: Reduced Optimism Bias in Self-Referential Belief Updating in High-Functioning Autism Type de document : Texte imprimé et/ou numérique Auteurs : B. KUZMANOVIC, Auteur ; L. RIGOUX, Auteur ; Kai VOGELEY, Auteur Article en page(s) : p.2990-2998 Langues : Anglais (eng) Mots-clés : Autism Belief updating Judgment Learning Optimism bias Rationality Index. décimale : PER Périodiques Résumé : Previous research has demonstrated irrational asymmetry in belief updating: people tend to take into account good news and neglect bad news. Contradicting formal learning principles, belief updates were on average larger after better-than-expected information than after worse-than-expected information. In the present study, typically developing subjects demonstrated this optimism bias in self-referential judgments. In contrast, adults with high-functioning autism spectrum disorder (ASD) were significantly less biased when updating self-referential beliefs (each group n = 21, matched for age, gender and IQ). These findings indicate a weaker influence of self-enhancing motives on prospective judgments in ASD. Reduced susceptibility to emotional and motivational biases in reasoning in ASD could elucidate impairments of social cognition, but may also confer important cognitive benefits.

Titre : Correlations Between Audiovisual Temporal Processing and Sensory Responsiveness in Adolescents with Autistic Traits Type de document : Texte imprimé et/ou numérique Auteurs : H. Y. ZHOU, Auteur ; H. X. YANG, Auteur ; L. J. SHI, Auteur ; S. S. Y. LUI, Auteur ; Eric F. C. CHEUNG, Auteur ; R. C. K.

Individuals with autism spectrum disorder (ASD) exhibit difficulties in processing the temporal aspects of sensory inputs, and show altered behavioural responses to sensory stimuli (i.e., sensory responsiveness). The present study examined the relation between sensory responsiveness (assessed by the Adult/Adolescent Sensory Profile) and audiovisual temporal integration (measured by unisensory temporal order judgement (TOJ) tasks and audiovisual simultaneity judgement (SJ) tasks) in typically-developing adolescents (n?=?94). We found that adolescents with higher levels of autistic traits exhibited more difficulties in separating visual stimuli in time (i.e., larger visual TOJ threshold) and showed a stronger bias to perceive sound-leading audiovisual pairings as simultaneous. Regarding the associations between different measures of sensory function, reduced visual temporal acuity, but not auditory or multisensory temporal processing, was significantly correlated with more atypical patterns of sensory responsiveness. Furthermore, the positive correlation between visual TOJ thresholds and sensory avoidance was only found in adolescents with relatively high levels of autistic traits, but not in those with relatively low levels of autistic traits. These findings suggest that reduced visual temporal acuity may contribute to altered sensory experiences and may be linked to broader behavioural characteristics of ASD.
