Brief Report: Preferred Processing of Social Stimuli in Autism: A Perception Task / A. MEERMEIER in Journal of Autism and Developmental Disorders, 52-7 (July 2022)
[article]
Titre : Brief Report: Preferred Processing of Social Stimuli in Autism: A Perception Task Type de document : Texte imprimé et/ou numérique Auteurs : A. MEERMEIER, Auteur ; M. JORDING, Auteur ; Y. ALAYOUBI, Auteur ; David H. V. VOGEL, Auteur ; Kai VOGELEY, Auteur ; R. TEPEST, Auteur Article en page(s) : p.3286-3293 Langues : Anglais (eng) Mots-clés : Autism Spectrum Disorder Autistic Disorder Humans Perception Social Perception Image persistence Image recognition Perception task Social stimuli Index. décimale : PER Périodiques Résumé : In this study we investigate whether persons with autism spectrum disorder (ASD) perceive social images differently than control participants (CON) in a graded perception task in which stimuli emerged from noise before dissipating into noise again. We presented either social stimuli (humans) or non-social stimuli (objects or animals). ASD were slower to recognize images during their emergence, but as fast as CON when indicating the dissipation of the image irrespective of its content. Social stimuli were recognized faster and remained discernable longer in both diagnostic groups. Thus, ASD participants show a largely intact preference for the processing of social images. An exploratory analysis of response subsets reveals subtle differences between groups that could be investigated in future studies.

Titre : Effect of Social Stimuli on Postural Responses in Individuals with Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Parisa GHANOUNI, Auteur ; Amir Hossein MEMARI, Auteur ; Shahriar GHARIBZADEH, Auteur ; Jandark EGHLIDI, Auteur ; Pouria MOSHAYEDI, Auteur Article en page(s) : p.1305-1313 Langues : Anglais (eng) Mots-clés : Autism quotient Postural sway Social stimuli Non-social stimuli Index. décimale : PER Périodiques Résumé : This study was aimed to investigate the effects of social versus non-social stimuli on postural responses in 21 boys with autism spectrum disorder (ASD) (mean age of 11.6?±?1.5) compared with 30 typically developing (TD) boys (mean age of 11.7?±?1.8). Postural control of children was examined while they were standing on a force plate and viewing images of an object, male face, or female face in sequence. Each image was shown in two trials and each trial lasted for 20 s. Results indicated a significant interaction between group and task (p?0.05), meaning that children with ASD but not TD children showed an increased postural sway during face tasks than during object task. Furthermore children with higher autism severity compared to those with lower severity showed an increased change in response to social stimuli (p?0.01). It seems that the postural control of children with ASD was more affected by the social stimuli than TD children.

Individuals with autism spectrum disorders (ASD) are thought to process rewards differently than typically developing (TD) individuals. However, there is little direct evidence to support this claim. Methods Two event-related potentials were measured. The stimulus preceding negativity (SPN) was utilized to measure reward anticipation, and the feedback related negativity (FRN) was utilized to measure reward processing. Participants were 6- to 8-year-olds with (N = 20) and without (N = 23) ASD. Children were presented with rewards accompanied by incidental face or nonface stimuli. Nonface stimuli were composed of scrambled face elements in the shape of arrows, controlling for low-level visual properties. Results Children with ASD showed smaller responses while anticipating and processing rewards accompanied by social stimuli than TD children. Anticipation and processing of rewards accompanied by nonsocial stimuli was intact in children with ASD. Conclusions This is the first study to measure both reward anticipation and processing in ASD while controlling for reward properties. The findings provide evidence that children with autism have reward anticipation and processing deficits for social stimuli only. Our results suggest that while typically developing children find social stimuli more salient than nonsocial stimuli, children with ASD may have the opposite preference.

The purpose of this study was to teach children with autism to attend to stimuli with socially relevant features. Specifically, this study evaluated a teaching package including rules, modeling, role play, and specific feedback across multiple exemplars to teach children with autism to attend and respond to others’ bids for social attention (e.g., “Whoa!” or “Ouch!”). Three participants successfully learned to shift attention toward others and emit a response to gain more information in response to a socially relevant stimulus. Furthermore, generalization was observed across novel exemplars and people.

Titre : Oscillatory rhythm of reward: anticipation and processing of rewards in children with and without autism Type de document : Texte imprimé et/ou numérique Auteurs : K. K. STAVROPOULOS, Auteur ; Leslie J. CARVER, Auteur Article en page(s) : 4p. Langues : Anglais (eng) Mots-clés : Alpha asymmetry Autism spectrum disorder Reward processing Social stimuli Theta Index. décimale : PER Périodiques Résumé : Background: Autism spectrum disorder (ASD) is a complex neurodevelopmental condition, and multiple theories have emerged concerning core social deficits. While the social motivation hypothesis proposes that deficits in the social reward system cause individuals with ASD to engage less in social interaction, the overly intense world hypothesis (sensory over-responsivity) proposes that individuals with ASD find stimuli to be too intense and may have hypersensitivity to social interaction, leading them to avoid these interactions. Methods: EEG was recorded during reward anticipation and reward processing. Reward anticipation was measured using alpha asymmetry, and post-feedback theta was utilized to measure reward processing. Additionally, we calculated post-feedback alpha suppression to measure attention and salience. Participants were 6- to 8-year-olds with (N = 20) and without (N = 23) ASD. Results: Children with ASD showed more left-dominant alpha suppression when anticipating rewards accompanied by nonsocial stimuli compared to social stimuli. During reward processing, children with ASD had less theta activity than typically developing (TD) children. Alpha activity after feedback showed the opposite pattern: children with ASD had greater alpha suppression than TD children. Significant correlations were observed between behavioral measures of autism severity and EEG activity in both the reward anticipation and reward processing time periods. Conclusions: The findings provide evidence that children with ASD have greater approach motivation prior to nonsocial (compared to social) stimuli. Results after feedback suggest that children with ASD evidence less robust activity thought to reflect evaluation and processing of rewards (e.g., theta) compared to TD children. However, children with ASD evidence greater alpha suppression after feedback compared to TD children. We hypothesize that post-feedback alpha suppression reflects general cognitive engagement-which suggests that children with ASD may experience feedback as overly intense. Taken together, these results suggest that aspects of both the social motivation hypothesis and the overly intense world hypothesis may be occurring simultaneously.
