Are Autistic and Alexithymic Traits Distinct? A Factor-Analytic and Network Approach / Hélio Clemente CUVE in Journal of Autism and Developmental Disorders, 52-5 (May 2022)

Increasing evidence, however, suggests that socioemotional difficulties may be explained by alexithymia, a distinct yet frequently co-occurring condition. If, as some propose, autistic traits are responsible for socioemotional impairments, then alexithymia may itself be a symptom of autism. We aimed to determine whether alexithymia should be considered a product of autism or regarded as a separate condition. Using factor-analytic and network approaches, we provide evidence that alexithymic and autistic traits are distinct. We argue that: (1) models of socioemotional processing in autism should conceptualise difficulties as intrinsic to alexithymia; and (2) assessment of alexithymia is crucial for diagnosis and personalised interventions.

Is it avoidance or hypoarousal? A systematic review of emotion recognition, eye-tracking, and psychophysiological studies in young adults with autism spectrum conditions / Hélio Clemente CUVE in Research in Autism Spectrum Disorders, 55 (November 2018)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 55 (November 2018) . - p.1-13 Titre : Is it avoidance or hypoarousal? A systematic review of emotion recognition, eye-tracking, and psychophysiological studies in young adults with autism spectrum conditions Type de document : Texte imprimé et/ou numérique Auteurs : Hélio Clemente CUVE, Auteur ; Yu GAO, Auteur ; Akiko FUSE, Auteur Article en page(s) : p.1-13 Langues : Anglais (eng) Mots-clés : Autism  Emotion  Eye-tracking  Arousal  Two-pathway  Model  Alexithymia Index. décimale : PER Périodiques Résumé : A systematic review was conducted for studies exploring the link between gaze patterns, autonomic arousal and emotion recognition deficits (ERD) in young adults with Autism Spectrum Conditions (ASC) in the context of the eye-avoidance/hyperarousal and the orientation/hypoarousal hypotheses. These hypotheses suggest that ERD in ASC can be explained by either exacerbated physiological arousal to eye-contact interfering with emotion recognition, or blunted arousal not engaging the necessary attention and awareness mechanisms to process emotionally salient cues, respectively. Most studies have suggested that individuals with ASC display an overall reduced attention to the eyes, however, this was not always associated with ERD, and some studies also reported ERD with no evidence of atypical gaze patterns. The evidence from psychophysiological studies is also mixed. While some studies supported that individuals with ASC are hypoaroused during emotion processing, others reported hyperarousal or even partially supported both. Overall, these results suggest that the current autonomic arousal and gaze hypotheses cannot fully account for ERD in ASC. A new integrative model is proposed, suggesting a two-pathway mechanism, in which avoidance and orientation processes might independently lead to ERD in ASC. Current methodological limitations, the influence of alexithymia, and implications are discussed.
