Early communication deficits in the Shank1 knockout mouse model for autism spectrum disorder: Developmental aspects and effects of social context / A. Özge SUNGUR in Autism Research, 9-6 (June 2016)  

Public ISBD [article]  inAutism Research > 9-6 (June 2016) . - p.696-709 Titre : Early communication deficits in the Shank1 knockout mouse model for autism spectrum disorder: Developmental aspects and effects of social context Type de document : Texte imprimé et/ou numérique Auteurs : A. Özge SUNGUR, Auteur ; Rainer K. W. SCHWARTING, Auteur ; Markus WÖHR, Auteur Article en page(s) : p.696-709 Langues : Anglais (eng) Mots-clés : animal model  postsynaptic density  neurodevelopmental disorders  autism  communication  ultrasonic vocalization  social context Index. décimale : PER Périodiques Résumé : Alterations in SHANK genes were repeatedly reported in autism spectrum disorder (ASD). ASD is a group of neurodevelopmental disorders diagnosed by persistent deficits in social communication/interaction across multiple contexts, with restricted/repetitive patterns of behavior. To date, diagnostic criteria for ASD are purely behaviorally defined and reliable biomarkers have still not been identified. The validity of mouse models for ASD therefore strongly relies on their behavioral phenotype. Here, we studied communication by means of isolation-induced pup ultrasonic vocalizations (USV) in the Shank1 mouse model for ASD by comparing Shank1?/? null mutant, Shank1+/? heterozygous, and Shank1+/+ wildtype littermate controls. The first aim of the present study was to evaluate the effects of Shank1 deletions on developmental aspects of communication in order to see whether ASD-related communication deficits are due to general impairment or delay in development. Second, we focused on social context effects on USV production. We show that Shank1?/? pups vocalized less and displayed a delay in the typical inverted U-shaped developmental USV emission pattern with USV rates peaking on postnatal day (PND) 9, resulting in a prominent genotype difference on PND6. Moreover, testing under social conditions revealed even more prominently genotype-dependent deficits regardless of the familiarity of the social context. As communication by definition serves a social function, introducing a social component to the typically nonsocial test environment could therefore help to reveal communication deficits in mouse models for ASD. Together, these results indicate that SHANK1 is involved in acoustic communication across species, with genetic alterations in SHANK1 resulting in social communication/interaction deficits.

Exploring social touch in autistic and non-autistic adults via a self-report body-painting task: The role of sex, social context and body area / Martina FUSARO ; Salvatore Maria AGLIOTI ; Ilaria MINIO-PALUELLO in Autism, 28-8 (August 2024)  

Public ISBD [article]  inAutism > 28-8 (August 2024) . - p.1985-2001 Titre : Exploring social touch in autistic and non-autistic adults via a self-report body-painting task: The role of sex, social context and body area Type de document : Texte imprimé et/ou numérique Auteurs : Martina FUSARO, Auteur ; Salvatore Maria AGLIOTI, Auteur ; Ilaria MINIO-PALUELLO, Auteur Article en page(s) : p.1985-2001 Langues : Anglais (eng) Mots-clés : appropriateness  autism spectrum disorder  erogeneity  pleasantness  social context  social touch Index. décimale : PER Périodiques Résumé : In the typically developing population, social touch experiences are influenced by several factors, including the biological sex of toucher and receiver, the body area wherein the touch is delivered and the social context in which the tactile exchange occurs. However, it is currently unexplored how social touch experiences of autistic adults are modulated by these factors. We sought to address this by utilizing a self-report body-painting task. Our main results show that autistic, compared with non-autistic, adults reported lower levels of pleasantness, erogeneity and appropriateness, specifically in intimate and friendly social contexts and in body areas typically touched in these situations. Importantly, sex played a major role in group differences. For instance, although autistic females reported, across social contexts, less pleasantness than both non-autistic females and autistic males, they experienced similar levels of appropriateness in the professional social context, usually deemed as touch-appropriate. Our findings provide new support to the hypothesis that social touch is experienced and possibly conceptualized differently by autistic compared with non-autistic adults. Moreover, by identifying the factors that influence social touch processing in autistic adults, our results might aid the development of support for autistic individuals seeking help in the spheres of social and intimate touch. Lay Abstract What is already known about the topic? At least in neurotypical individuals, social touch represents an important channel for emotional communication associated with social bonding and pain/anxiety modulation. Autistic adults report to avoid social touch more and to have different tactile sensitivity than their non-autistic comparisons. What this paper adds? Few studies specifically investigated social touch in autistic individuals, and none of them examined the role of participants'sex, social context in which social touch occurs, and specific body areas being touched. In our study, adult participants reported how pleasant, erogenous and appropriate they would consider touches delivered by another person over their entire body in intimate (date), friendly (dance class) and professional (physiotherapy-massage session) social contexts. Autistic adults reported social touch to be less pleasant, erogenous and appropriate specifically in intimate and friendly social contexts and in body areas typically touched in these situations. Importantly, autistic females seem more at risk to experience unpleasant social touch as, although they considered it more unpleasant than non-autistic females and autistic males, they did consider it similarly appropriate in professional social contexts where touch is normed to be socially appropriate. Implications for practice, research or policy Our results might improve awareness and understanding about autistic adults'different, and often more discomforting, experience of social touch and thus help consider and respect it during everyday social interactions. Our results might also benefit future research investigating, for instance, the neural underpinnings of social touch differences in autism or aiming at developing support for autistic individuals seeking help in the diverse spheres of social touch.

Exploring the autism spectrum: Moderating effects of neuroticism on stress reactivity and on the association between social context and negative affect / Jeroen VAN OOSTERHOUT in Development and Psychopathology, 34-4 (October 2022)

In autism spectrum disorders (ASD), emotional stress reactivity is increased and there is some evidence for an increased negative affect (NA) when with less familiar people. The aim of this study was to compare adults with ASD and controls on levels of neuroticism and on interactions between neuroticism and appraised stress or social context in models of NA. This is a cross-sectional observational study comprising a group of 50 adults with ASD and 51 controls. Experience sampling method (ESM) reports were collected for 10 days to measure daily life stress, mood, and social context. Multilevel regression analyses revealed significantly higher neuroticism levels in ASD than in controls. Adults with ASD who scored high on neuroticism showed a significantly stronger association between activity/social stress and NA (i.e., higher stress reactivity) than those with low scores. Furthermore, the association between neuroticism and NA was stronger when adults with ASD were with less familiar people compared with being alone or with familiar people. No consistent corresponding significant interactions were found in the control group. In conclusion, in ASD, neuroticism moderates the association between appraised stress and NA as well as the association between social context and NA.

Self-Conscious Emotion Processing in Autistic Adolescents: Over-Reliance on Learned Social Rules During Tasks with Heightened Perspective-Taking Demands May Serve as Compensatory Strategy for Less Reflexive Mentalizing / K.

We investigated self-conscious emotion (SCE) processing in autistic and neurotypical adolescents. Participants watched videos of peers acting embarrassed and proud and rated inferred and empathic SCEs. We compared intensity ratings across groups and conducted correlations with social cognitive abilities and autistic features. Autistic adolescents recognized SCEs and felt empathic SCEs; however, they made atypical emotion attributions when perspective-taking demands were high, which more strongly reflected the situational context. Atypical attributions were associated with perspective-taking difficulties and autistic feature intensity. An over-reliance on contextual cues may reflect a strict adherence to learned social rules, possibly compensating for less reflexive mentalizing, which may underlie interpersonal challenges in ASD.

However, researchers often use stimuli that conflate salient emotional and social information. Using a matched-pairs design, the impact of emotional and social information on emotional language in pre-school and school-age children, with and without ASD, was assessed with a picture description task comprising rated stimuli from the Pictures with Social Contexts and Emotional Scenes database (Teh et al. in Behav Res Methods, https://doi.org/10.3758/s13428-017-0947-x , 2017). Results showed both groups with ASD produced fewer emotional terms than typically developing children, but the effects were moderated by valence, social engagement, and age. Implications for theory and clinical practice are discussed.
