Separate contributions of autistic traits and anxious apprehension, but not alexithymia, to emotion processing in faces / K. G. STEPHENSON in Autism, 23-7 (October 2019)
[article]
Titre : Separate contributions of autistic traits and anxious apprehension, but not alexithymia, to emotion processing in faces Type de document : Texte imprimé et/ou numérique Auteurs : K. G. STEPHENSON, Auteur ; S. G. LUKE, Auteur ; M. SOUTH, Auteur Article en page(s) : p.1830-1842 Langues : Anglais (eng) Mots-clés : alexithymia anxious apprehension autism emotion eye fixation eye tracking mixed-effects modeling worry Index. décimale : PER Périodiques Résumé : Reduced eye fixation has been commonly reported in autistic samples but may be at least partially explained by alexithymia (i.e., difficulty understanding and describing one's emotional state). Because anxiety is often elevated in autism, and emotion-processing differences have also been observed in anxious samples, anxiety traits may also influence emotion processing within autism. This study tested the contribution of dimensional traits of autism, anxious apprehension, and alexithymia in mediating eye fixation during face processing. Participants included 105 adults from three samples: autistic adults (AS; n = 30), adults with clinically elevated anxiety and no autism (HI-ANX; n = 29), and neurotypical adults without elevated anxiety (NT; n = 46). Experiment 1 used an emotion identification task with dynamic stimuli, while Experiment 2 used a static luminance change detection task with emotional- and neutral-expression static photos. The emotions of interest were joy, anger, and fear. Dimensional mixed-effects models showed that autism traits, but not alexithymia, predicted reduced eye fixation across both tasks. Anxious apprehension was negatively related to response time in Experiment 1 and positively related to eye fixation in Experiment 2. Attentional avoidance of negative stimuli occurred at lower levels of autism traits and higher levels of worry traits. The results highlight the contribution of autism traits to emotional processing and suggest additional effects of worry-related traits.

Titre : Visual scanning and recognition of ambiguous faces in children with autism: The effects of morphing levels and facial identities Type de document : Texte imprimé et/ou numérique Auteurs : Yige WANG, Auteur ; Zhi SHAO, Auteur ; Libin ZHANG, Auteur ; Tingyong FENG, Auteur Article en page(s) : 101931 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Face recognition Eye fixation Face scanning Familiarity Index. décimale : PER Périodiques Résumé : Background and aim Prior work on face processing in children with autism spectrum disorder (ASD) has mainly focused on the investigation of unfamiliar faces. The present study aimed to extend earlier research by the inclusion of the different faces with varying levels of perceptual difficulty. Methods We employed eye-tracking and morphing techniques to measure face recognition involving identification of face morphs and to record eye movements during the task. Three groups of children participated in the study, comprising 24 with ASD (aged from 4 to 7 years), 25 verbal IQ (VQ)-matched typical developing (TD) controls (aged from 3 to 4 years), and 25 chronological age (CA)-matched TD controls (aged from 4 to 6 years). Results The group-difference was specific for morphed unknown faces – ASD children had a decreased judgement of unknown faces and showed a lower specificity. Concurrent eye-tracking further provided mechanistic insights: the ASD group exhibited a significant reduction in eye-region fixation when recognizing ambiguous unknown faces, relative to both TD groups. Conclusion The current study provides evidence of a selective difficulty in the identification of unknown faces in ASD when the perceptual demand increased, without atypicality in self and familiar face processing. Reduced attention and social interest may be responsible for difficulties in response to stranger faces in young ASD children, rather than a consequence of inability.
