New research in 'Journal of Autism and Developmental Disorders' shows that attitudes toward social touch play a central role in how autistic adults experience touch, influencing perceptions of pleasantness, appropriateness, and erogeneity. bit.ly/48V81Pb @mmellon.bsky.social #AcademicSky #EduSky

Centrality of Touch Avoidance in Social Touch Experiences in Autism - Journal of Autism and Developmental Disorders

Purpose Social touch is ubiquitous in social species, and it represents an important driving force of human development. Mounting evidence suggests that social touch may be perceived and processed differently in autistic and neurotypical individuals. For instance, feelings of erogeneity, pleasantness, and appropriateness of social touch throughout the whole body and in different contexts were reported to be overall lower by autistic adults, compared with a non-autistic sample, and that participants’ sex modulated these feelings differently in the two groups. Here, we expand on these findings by taking a multidimensional approach and exploring individual traits that might be linked to social touch processing differences in autism. Methods We implemented exploratory network analysis and moderated parallel mediation analyses considering measures of attitudes towards social touch, non-social touch sensitivity, social anxiety, and alexithymia. We investigated how these individual dispositions might impact group differences in social touch erogeneity, pleasantness, and appropriateness, and evaluated how sex assigned at birth might moderate these relationships. Results Both exploratory and confirmatory analysis approaches converged in showing that one’s attitude toward social touch represents a central disposition contributing to lower levels of social touch erogeneity, pleasantness, and appropriateness in autistic individuals. Moreover, these mediation relationships were stronger in autistic male participants. Conclusion These results pave the way for a deeper, more targeted investigation of the structure and dy namics underlying the relationships between social touch processing differences in autism and specific individual dispositions. Moreover, they bring about new evidence on how the sex of the receiver might influence such social touch experiences.

New challenge: A daily read, for at least one month, of a Neuroscience article not necessarily related to my field of research. (Clearly, to sum to those I "need" to read 😂.) Today's: "The socio-temporal brain: connecting people in time" by Schirmer et al., 2016. #Neuroskyence | #CogSci | #brain

What is, in your opinion, the best (contemporary) book giving an overarching view of brain functioning relating to complex behavior? #Neuroskyence | #CogSci | #PsychSciSky |
