Alexithymia, but not autism spectrum disorder, may be related to the production of emotional facial expressions / D. A. TREVISAN in Molecular Autism, 7 (2016)
[article]
Titre : Alexithymia, but not autism spectrum disorder, may be related to the production of emotional facial expressions Type de document : Texte imprimé et/ou numérique Auteurs : D. A. TREVISAN, Auteur ; M. BOWERING, Auteur ; Elina BIRMINGHAM, Auteur Article en page(s) : 46p. Langues : Anglais (eng) Mots-clés : Adolescent Affective Symptoms/physiopathology/psychology Autism Spectrum Disorder/classification/physiopathology/psychology Case-Control Studies Child Facial Expression Female Humans Male Pattern Recognition, Automated/statistics & numerical data Social Perception Software Alexithymia Autism Facial expressions Index. décimale : PER Périodiques Résumé : BACKGROUND: A prominent diagnostic criterion of autism spectrum disorder (ASD) relates to the abnormal or diminished use of facial expressions. Yet little is known about the mechanisms that contribute to this feature of ASD. METHODS: We showed children with and without ASD emotionally charged video clips in order to parse out individual differences in spontaneous production of facial expressions using automated facial expression analysis software. RESULTS: Using hierarchical multiple regression, we sought to determine whether alexithymia (characterized by difficulties interpreting one's own feeling states) contributes to diminished facial expression production. Across groups, alexithymic traits-but not ASD traits, IQ, or sex-were associated with quantity of facial expression production. CONCLUSIONS: These results accord with a growing body of research suggesting that many emotion processing abnormalities observed in ASD may be explained by co-occurring alexithymia. Developmental and clinical considerations are discussed, and it is argued that alexithymia is an important but too often ignored trait associated with ASD that may have implications for subtyping individuals on the autism spectrum.

[article]
Titre : Emotional decision-making in autism spectrum disorder: the roles of interoception and alexithymia Type de document : Texte imprimé et/ou numérique Auteurs : P. SHAH, Auteur ; Caroline CATMUR, Auteur ; Geoffrey BIRD, Auteur Article en page(s) : 43p. Langues : Anglais (eng) Mots-clés : Adult Affective Symptoms/physiopathology/psychology Autism Spectrum Disorder/physiopathology/psychology Case-Control Studies Decision Making Female Frustration Happiness Humans Intelligence Tests Interoception/physiology Male Alexithymia Autism Decision-making Emotion Framing effect Insula Interoception Replication Index. décimale : PER Périodiques Résumé : The way choices are framed influences decision-making. These "framing effects" emerge through the integration of emotional responses into decision-making under uncertainty. It was previously reported that susceptibility to the framing effect was reduced in individuals with autism spectrum disorder (ASD) due to a reduced tendency to incorporate emotional information into the decision-making process. However, recent research indicates that, where observed, emotional processing impairments in ASD may be due to co-occurring alexithymia. Alexithymia is thought to arise due to impaired interoception (the ability to perceive the internal state of one's body), raising the possibility that emotional signals are not perceived and thus not integrated into decision-making in those with alexithymia and that therefore reduced framing effects in ASD are a product of co-occurring alexithymia rather than ASD per se. Accordingly, the present study compared framing effects in autistic individuals with neurotypical controls matched for alexithymia. Results showed a marked deviation between groups. The framing effect was, in line with previous data, significantly smaller in autistic individuals, and there was no relationship between alexithymia or interoception and decision-making in the ASD group. In the neurotypical group, however, the size of the framing effect was associated with alexithymia and interoception, even after controlling for autistic traits. These results demonstrate that although framing effects are associated with interoception and alexithymia in the neurotypical population, emotional and interoceptive signals have less impact upon the decision-making process in ASD.
