However, it is not clear whether such cross-neurotype differences extend to prosocial decision-making behaviour – something that is vital for forming and maintaining social bonds. Using a physical-effort-based decision-making paradigm, in combination with computational modelling, we examined 30 autistic and 30 non-autistic individuals’ prosocial willingness to exert physical effort for oneself and others, as a function of whether the beneficiary shares their neurotype or not. We compared decisions to exert effort and action energisation when participants made decisions for the Self, Other Same neurotype and Other Different neurotype. Results showed a robust self-bias in effort discounting, with both groups choosing to exert more effort for themselves than others, and no differences between same and different neurotype others. However, while non-autistic participants showed no difference in action energisation between the same and different neurotype others, autistic participants exerted significantly more force for others of the same neurotype. Implicit, but not explicit, biases held about autism played a role: in autistic participants, higher implicit autism stigma predicted differences in effort discounting between same and different neurotype others, while in non-autistic participants, implicit bias predicted differences in actual effort exerted rather than decision-making. This work has important implications for understanding how interactor neurotypes and autism-specific biases may feed into prosocial decision-making contexts such as employment, health and education settings, where autistic individuals face the everyday consideration of whether to disclose their diagnostic status.

Comparing internal representations of facial expression kinematics between autistic and non-autistic adults / Connor T. KEATING in Autism Research, 15-3 (March 2022)  

Public ISBD [article]  inAutism Research > 15-3 (March 2022) . - p.493-506 Titre : Comparing internal representations of facial expression kinematics between autistic and non-autistic adults Type de document : texte imprimé Auteurs : Connor T. KEATING, Auteur ; Sophie SOWDEN, Auteur ; Jennifer L. COOK, Auteur Article en page(s) : p.493-506 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Abstract Recent developments suggest that autistic individuals require dynamic angry expressions to have a higher speed in order for them to be successfully identified. Therefore, it is plausible that autistic individuals do not have a ?deficit? in angry expression recognition, but rather their internal representation of these expressions is characterised by very high-speed movement. In this study, matched groups of autistic and non-autistic adults completed a novel emotion-based task which employed dynamic displays of happy, angry and sad point light facial (PLF) expressions. On each trial, participants moved a slider to manipulate the speed of a PLF stimulus until it moved at a speed that, in their ?mind's eye?, was typical of happy, angry or sad expressions. Participants were shown three different types of PLFs?those showing the full-face, only the eye region, and only the mouth region, wherein the latter two were included to test whether differences in facial information sampling underpinned any dissimilarities in speed attributions. Across both groups, participants attributed the highest speeds to angry, then happy, then sad, facial motion. Participants increased the speed of angry and happy expressions by 41% and 27% respectively and decreased the speed of sad expressions by 18%. This suggests that participants have ?caricatured? internal representations of emotion, wherein emotion-related kinematic cues are over-emphasised. There were no differences between autistic and non-autistic individuals in the speeds attributed to full-face and partial-face angry, happy and sad expressions respectively. Consequently, we find no evidence that autistic adults possess atypically fast internal representations of anger.

Differences Between Autistic and Non-Autistic Adults in the Recognition of Anger from Facial Motion Remain after Controlling for Alexithymia / Connor T. KEATING in Journal of Autism and Developmental Disorders, 52-4 (April 2022)

Here, autistic and non-autistic adults (N=60) matched on age, gender, non-verbal reasoning ability and alexithymia, completed an emotion recognition task, which employed dynamic point light displays of emotional facial expressions manipulated in terms of speed and spatial exaggeration. Autistic participants exhibited significantly lower accuracy for angry, but not happy or sad, facial motion with unmanipulated speed and spatial exaggeration. Autistic, and not alexithymic, traits were predictive of accuracy for angry facial motion with unmanipulated speed and spatial exaggeration. Alexithymic traits, in contrast, were predictive of the magnitude of both correct and incorrect emotion ratings.
