The ability to recognize a person’s actions, subjective states, emotions, and objects conveyed by moving point-light displays was assessed in 19 participants with autism and 19 comparable typical control participants. Results showed that the participants with autism were as able as controls to name point-light displays of non-human objects and human actions. In contrast, they were significantly poorer at labeling emotional displays, suggesting that they are specifically impaired in attending to emotional states. Most studies have highlighted an emotional deficit in facial expression perception; our results extend this hypothesized deficit to the perception and interpretation of whole-body biological movements.

Electrodermal reactivity to emotion processing in adults with autistic spectrum disorders / Bénédicte HUBERT in Autism, 13-1 (January 2009)  

Public ISBD [article]  inAutism > 13-1 (January 2009) . - p.9-19 Titre : Electrodermal reactivity to emotion processing in adults with autistic spectrum disorders Type de document : texte imprimé Auteurs : Bénédicte HUBERT, Auteur ; Bruno WICKER, Auteur ; Elisabetta MONFARDINI, Auteur ; Christine DERUELLE, Auteur Année de publication : 2009 Article en page(s) : p.9-19 Langues : Anglais (eng) Mots-clés : autism electrodermal-responses facial-emotion-processing Index. décimale : PER Périodiques Résumé : Although alterations of emotion processing are recognized as a core component of autism, the level at which alterations occur is still debated. Discrepant results suggest that overt assessment of emotion processing is not appropriate. In this study, skin conductance response (SCR) was used to examine covert emotional processes. Both behavioural responses and SCRs of 16 adults with an autistic spectrum disorder (ASD) were compared to those of 16 typical matched adults. Participants had to judge emotional facial expressions, the age of faces or the direction of a moving object. Although behavioural performance was similar in the two populations, individuals with an ASD exhibited lower SCRs than controls in the emotional judgement task. This suggests that such individuals may rely on different strategies due to altered autonomic processing. Furthermore, failure to produce normal physiological reactions to emotional faces may be related to social impairments in individuals with an ASD.

Olfactory processing in adults with autism spectrum disorders / Bruno WICKER in Molecular Autism, 7 (2016)  

Public ISBD [article]  inMolecular Autism > 7 (2016) . - 4p. Titre : Olfactory processing in adults with autism spectrum disorders Type de document : texte imprimé Auteurs : Bruno WICKER, Auteur ; Elisabetta MONFARDINI, Auteur ; Jean-Pierre ROYET, Auteur Article en page(s) : 4p. Langues : Anglais (eng) Mots-clés : Adult  Autism Spectrum Disorder/physiopathology/psychology  Differential Threshold/physiology  Emotions/physiology  Female  Humans  Hyperesthesia/etiology/physiopathology/psychology  Hypesthesia/etiology/physiopathology/psychology  Male  Odorants  Olfactory Pathways/physiopathology  Olfactory Perception/physiology  Pleasure  Recognition (Psychology)/physiology  Sensory Thresholds  Young Adult  Autism spectrum disorders  Hyperresponsiveness  Identification  Intensity  Olfaction  Pleasantness  Suprathreshold detection Index. décimale : PER Périodiques Résumé : BACKGROUND: As evidenced in the DSM-V, autism spectrum disorders (ASD) are often characterized by atypical sensory behavior (hyper- or hypo-reactivity), but very few studies have evaluated olfactory abilities in individuals with ASD. METHODS: Fifteen adults with ASD and 15 typically developing participants underwent olfactory tests focused on superficial (suprathreshold detection task), perceptual (intensity and pleasantness judgment tasks), and semantic (identification task) odor processing. RESULTS: In terms of suprathreshold detection performance, decreased discrimination scores and increased bias scores were observed in the ASD group. Furthermore, the participants with ASD exhibited increased intensity judgment scores and impaired scores for pleasantness judgments of unpleasant odorants. Decreased identification performance was also observed in the participants with ASD compared with the typically developing participants. This decrease was partly attributed to a higher number of near misses (a category close to veridical labels) among the participants with ASD than was observed among the typically developing participants. CONCLUSIONS: The changes in discrimination and bias scores were the result of a high number of false alarms among the participants with ASD, which suggests the adoption of a liberal attitude in their responses. Atypical intensity and pleasantness ratings were associated with hyperresponsiveness and flattened emotional reactions, respectively, which are typical of participants with ASD. The high number of near misses as non-veridical labels suggested that categorical processing is functional in individuals with ASD and could be explained by attention-deficit/hyperactivity disorder. These findings are discussed in terms of dysfunction of the olfactory system.

Recognition of biological motion in children with autistic spectrum disorders / Carole PARRON in Autism, 12-3 (May 2008)

Most relevant studies have explored the perception of faces. However, context and bodily gestures are also sources from which we derive emotional meanings. We tested 23 autistic children and 23 typically developing control children on their ability to recognize point-light displays of a person's actions, subjective states and emotions. In a control task, children had to recognize point-light displays of everyday objects. The children with autism only differed from the control children in their ability to name the emotional point-light displays. This suggests that children with autism can extract complex meanings from bodily movements but may be less sensitive to higher-order emotional information conveyed by human movement. The results are discussed in the context of a specific deficit in emotion perception in children with autism.
