Altered Medial Frontal and Superior Temporal Response to Implicit Processing of Emotions in Autism / Rajesh K. KANA in Autism Research, 9-1 (January 2016)

CHANNELL, Auteur ; Bruno WICKER, Auteur Article en page(s) : p.55-66 Langues : Anglais (eng) Mots-clés : implicit emotion  explicit emotion  fMRI  functional connectivity  autism Index. décimale : PER Périodiques Résumé : Interpreting emotional expressions appropriately poses a challenge for individuals with autism spectrum disorder (ASD). In particular, difficulties with emotional processing in ASD are more pronounced in contexts where emotional expressions are subtle, automatic, and reflexive—that is, implicit. In contrast, explicit emotional processing, which requires the cognitive evaluation of an emotional experience, appears to be relatively intact in individuals with ASD. In the present study, we examined the brain activation and functional connectivity differences underlying explicit and implicit emotional processing in age- and IQ-matched adults with (n?=?17) and without (n?=?15) ASD. Results indicated: (1) significantly reduced levels of brain activation in participants with ASD in medial prefrontal cortex (MPFC) and superior temporal gyrus (STG) during implicit emotion processing; (2) significantly weaker functional connectivity in the ASD group in connections of the MPFC with the amygdala, temporal lobe, parietal lobe, and fusiform gyrus; (3) No group difference in performance accuracy or reaction time; and (4) Significant positive relationship between empathizing ability and STG activity in ASD but not in typically developing participants. These findings suggest that the neural mechanisms underlying implicit, but not explicit, emotion processing may be altered at multiple levels in individuals with ASD.

Brief Report: Recognition of Emotional and Non-emotional Biological Motion in Individuals with Autistic Spectrum Disorders / Bénédicte HUBERT in Journal of Autism and Developmental Disorders, 37-7 (August 2007)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 37-7 (August 2007) . - p.1386-1392 Titre : Brief Report: Recognition of Emotional and Non-emotional Biological Motion in Individuals with Autistic Spectrum Disorders Type de document : Texte imprimé et/ou numérique Auteurs : Bénédicte HUBERT, Auteur ; Bruno WICKER, Auteur ; Derek G.

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 et/ou numérique 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.

Negative emotion does not enhance recall skills in adults with autistic spectrum disorders / Christine DERUELLE in Autism Research, 1-2 (April 2008)  

Public ISBD [article]  inAutism Research > 1-2 (April 2008) . - p.91-96 Titre : Negative emotion does not enhance recall skills in adults with autistic spectrum disorders Type de document : Texte imprimé et/ou numérique Auteurs : Christine DERUELLE, Auteur ; Bénédicte HUBERT, Auteur ; Bruno WICKER, Auteur ; Andreia SANTOS, Auteur Année de publication : 2008 Article en page(s) : p.91-96 Langues : Anglais (eng) Mots-clés : emotion memory valence autism Index. décimale : PER Périodiques Résumé : Recent empirical findings suggest a significant influence of emotion on memory processes. Surprisingly, although emotion-processing difficulties appear to be a hallmark feature in autism spectrum disorders (ASD), their impact on higher-level cognitive functions, such as memory, has not been directly studied in this population. The aim of this study was to address this issue by assessing whether the emotional valence of visual scenes affects recall skills in high-functioning individuals with ASD. To this purpose, their recall performance of neutral and emotional pictures was compared with that of typically developing adults (control group). Results revealed that while typically developing individuals showed enhanced recall skills for negative relative to positive and neutral pictures, individuals with ASD recalled the neutral pictures as well as the emotional ones. Findings of this study thus point to reduced influence of emotion on memory processes in ASD than in typically developing individuals, possibly owing to amygdala dysfunctions.
