Virtual Reality Immersion Rescales Regulation of Interpersonal Distance in Controls but not in Autism Spectrum Disorder / Marco SIMÕES in Journal of Autism and Developmental Disorders, 50-12 (December 2020)
[article]
Titre : Virtual Reality Immersion Rescales Regulation of Interpersonal Distance in Controls but not in Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Marco SIMÕES, Auteur ; Susana MOUGA, Auteur ; Andreia C. PEREIRA, Auteur ; Paulo DE CARVALHO, Auteur ; Guiomar OLIVEIRA, Auteur ; Miguel CASTELO-BRANCO, Auteur Article en page(s) : p.4317-4328 Langues : Anglais (eng) Mots-clés : Asd Interpersonal distance Personal space regulation Virtual reality Virtual rehabilitation Index. décimale : PER Périodiques Résumé : Interpersonal distance (IPD) is a simple social regulation metric which is altered in autism. We performed a stop-distance paradigm to evaluate IPD regulation in autism spectrum disorder (ASD) and control groups in a real versus a virtual environment mimicking in detail the real one. We found a bimodal pattern of IPDs only in ASD. Both groups showed high IPD correlations between real and virtual environments, but the significantly larger slope in the control group suggests rescaling, which was absent in ASD. We argue that loss of nuances like non-verbal communication, such as perception of subtle body gestures in the virtual environment, lead to changed regulation of IPD in controls, whilst ASD participants show similar deficits in perceiving such subtle cues in both environments.

[article]
Titre : Personal space regulation in childhood autism: Effects of social interaction and person's perspective Type de document : Texte imprimé et/ou numérique Auteurs : Michela CANDINI, Auteur ; Virginia GIUBERTI, Auteur ; Alessandra MANATTINI, Auteur ; Serenella GRITTANI, Auteur ; Giuseppe DI PELLEGRINO, Auteur ; Francesca FRASSINETTI, Auteur Article en page(s) : p.144-154 Langues : Anglais (eng) Mots-clés : interpersonal distance autism social interaction perspective taking Index. décimale : PER Périodiques Résumé : Studies in children with Typical Development (TD) and with Autism Spectrum Disorder (ASD) revealed that autism affects the personal space regulation, influencing both its size (permeability) and its changes depending on social interaction (flexibility). Here, we investigate how the nature of social interaction (Cooperative vs. Uncooperative) and the person perspective influence permeability and flexibility of interpersonal distance. Moreover, we tested whether the deficit observed in ASD children, reflects the social impairment (SI) in daily interactions. The stop-distance paradigm was used to measure the preferred distance between the participant and an unfamiliar adult (first-person perspective, Experiment 1), and between two other people (third-person perspective, Experiment 2). Interpersonal distance was measured before and after the interaction with a confederate. The Wing Subgroups Questionnaire was used to evaluate SI in everyday activities, and each ASD participant was accordingly assigned either to the lower (children with low social impairment [low-SI ASD]), or to the higher SI group (children with high social impairment [high-SI ASD]). We observed larger interpersonal distance (permeability) in both ASD groups compared to TD children. Moreover, depending on the nature of social interaction, a modulation of interpersonal distance (flexibility) was observed in TD children, both from the first- and third-person perspective. Similar findings were found in low-SI but not in high-SI ASD children, in Experiment 1. Conversely, in Experiment 2, no change was observed in both ASD groups. These findings reveal that SI severity and a person's perspective may account for the deficit observed in autism when flexibility, but not permeability, of personal space is considered.

[article]
Titre : Personal Space Regulation in Williams Syndrome: The Effect of Familiarity Type de document : Texte imprimé et/ou numérique Auteurs : Emma LOUGH, Auteur ; Emma FLYNN, Auteur ; Deborah M. RIBY, Auteur Article en page(s) : p.3207-3215 Langues : Anglais (eng) Mots-clés : Williams syndrome Personal space Interpersonal distance Stop-distance Social behaviour Index. décimale : PER Périodiques Résumé : Personal space refers to a protective barrier that we strive to maintain around our body. We examined personal space regulation in young people with Williams syndrome (WS) and their typically developing, chronological age-matched peers using a parent report questionnaire and a stop-distance paradigm. Individuals with WS were reported by their parents to be more likely to violate the personal space of others, and indeed they maintained a shorter interpersonal distance in the stop-distance paradigm. Interestingly, WS individuals failed to regulate their personal space based on the familiarity of the person they were interacting with. Findings are discussed in relation to the wider social profile associated with WS, and the possible impact of atypical personal space regulation on social vulnerability.

Nineteen high function children with higher functioning Autism Spectrum Disorder (HFASD) and 23 age, gender, and IQ matched children with typical development (TD) used a joy stick to position themselves closer or further from virtual avatars while attempting to identify six emotions expressed by the avatars, happiness, fear, anger, disgust, sadness, and surprise that were expressed at different levels of intensity. The results indicated that children with HFASD displayed significantly less approach behavior to the positive happy expression than did children with TD, who displayed increases in approach behavior to higher intensities of happy expressions. Alternatively, all groups tended to withdraw from negative emotions to the same extent and there were no diagnostic group differences in accuracy of recognition of any of the six emotions. This pattern of results is consistent with theory that suggests that some children with HFASD display atypical social-approach motivation, or sensitivity to the positive reward value of positive social–emotional events. Conversely, there was little evidence that a tendency to withdraw from social–emotional stimuli, or a failure to process social emotional stimuli, was a component of social behavior task performance in this sample of children with HFASD.
