Associations between emotion recognition and autistic and callous-unemotional traits: differential effects of cueing to the eyes / Virginia CARTER LENO in Journal of Child Psychology and Psychiatry, 64-5 (May 2023)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 64-5 (May 2023) . - p.787-796 Titre : Associations between emotion recognition and autistic and callous-unemotional traits: differential effects of cueing to the eyes Type de document : Texte imprimé et/ou numérique Auteurs : Virginia CARTER LENO, Auteur ; Hannah PICKARD, Auteur ; Liliana CYBULSKA, Auteur ; Tim SMITH, Auteur ; Marcus MUNAFO, Auteur ; Ian PENTON-VOAK, Auteur ; Emily SIMONOFF, Auteur ; Andrew PICKLES, Auteur ; Rachael BEDFORD, Auteur Article en page(s) : p.787-796 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Background Although autism and callous-unemotional (CU) traits are distinct conditions, both are associated with difficulties in emotion recognition. However, it is unknown whether the emotion recognition difficulties characteristic of autism and CU traits are driven by comparable underpinning mechanisms. Methods We tested whether cueing to the eyes improved emotion recognition in relation to autistic and CU traits in a heterogeneous sample of children enhanced for social, emotional and behavioural difficulties. Participants were 171 (n = 75 male) children aged 10-16?years with and without a diagnosis of autism (n = 99 autistic), who completed assessments of emotion recognition with and without cueing to the eyes. Parents completed the assessment of autistic and CU traits. Results Associations between autistic and CU traits and emotion recognition accuracy were dependent upon gaze cueing. CU traits were associated with an overall decrease in emotion recognition in the uncued condition, but better fear recognition when cued to the eyes. Conversely, autistic traits were associated with decreased emotion recognition in the cued condition only, and no interactions between autistic traits and emotion were found. Conclusions The differential effect of cueing to the eyes in autistic and CU traits suggests different mechanisms underpin emotion recognition abilities. Results suggest interventions designed to promote looking to the eyes may be beneficial for children with CU traits, but not for children with autistic characteristics. Future developmental studies of autism and CU characteristics are required to better understand how different pathways lead to overlapping socio-cognitive profiles.

Saccade dysmetria indicates attenuated visual exploration in autism spectrum disorder / Nico BAST in Journal of Child Psychology and Psychiatry, 62-2 (February 2021)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 62-2 (February 2021) . - p.149-159 Titre : Saccade dysmetria indicates attenuated visual exploration in autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Nico BAST, Auteur ; Luke MASON, Auteur ; Christine M. FREITAG, Auteur ; Tim SMITH, Auteur ; Ana Maria PORTUGAL, Auteur ; Luise POUSTKA, Auteur ; Tobias BANASCHEWSKI, Auteur ; Mark H. JOHNSON, Auteur Année de publication : 2021 Article en page(s) : p.149-159 Langues : Anglais (eng) Mots-clés : Eye tracking  biomarker  brainstem  cerebellum  locus coeruleus  pupillometry  visual attention Index. décimale : PER Périodiques Résumé : BACKGROUND: Visual exploration in autism spectrum disorder (ASD) is characterized by attenuated social attention. The underlying oculomotor function during visual exploration is understudied, whereas oculomotor function during restricted viewing suggested saccade dysmetria in ASD by altered pontocerebellar motor modulation. METHODS: Oculomotor function was recorded using remote eye tracking in 142 ASD participants and 142 matched neurotypical controls during free viewing of naturalistic videos with and without human content. The sample was heterogenous concerning age (6-30 years), cognitive ability (60-140 IQ), and male/female ratio (3:1). Oculomotor function was defined as saccade, fixation, and pupil-dilation features that were compared between groups in linear mixed models. Oculomotor function was investigated as ASD classifier and features were correlated with clinical measures. RESULTS: We observed decreased saccade duration (?M = -0.50, CI [-0.21, -0.78]) and amplitude (?M = -0.42, CI [-0.12, -0.72]), which was independent of human video content. We observed null findings concerning fixation and pupil-dilation features (POWER = .81). Oculomotor function is a valid ASD classifier comparable to social attention concerning discriminative power. Within ASD, saccade features correlated with measures of restricted and repetitive behavior. CONCLUSIONS: We conclude saccade dysmetria as ASD oculomotor phenotype relevant to visual exploration. Decreased saccade amplitude and duration indicate spatially clustered fixations that attenuate visual exploration and emphasize endogenous over exogenous attention. We propose altered pontocerebellar motor modulation as underlying mechanism that contributes to atypical (oculo-)motor coordination and attention function in ASD.
