Atypical physiological orienting to direct gaze in low-functioning children with autism spectrum disorder / Terhi M. HELMINEN in Autism Research, 10-5 (May 2017)  

Public ISBD [article]  inAutism Research > 10-5 (May 2017) . - p.810-820 Titre : Atypical physiological orienting to direct gaze in low-functioning children with autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Terhi M.

It has been proposed that direct gaze does not capture the attention of individuals with ASD. Experimental evidence is, however, mainly restricted to relatively high-functioning school-aged children or adults with ASD. This study investigated whether 2–5-year-old low-functioning children with severe ASD differ from control children in orienting to gaze stimuli, as measured with the heart rate deceleration response. Responses were measured to computerized presentations of dynamic shifts of gaze direction either toward (direct) or away (averted) from the observing child. The results showed a significant group by gaze direction interaction effect on heart rate responses (permuted P?=?.004), reflecting a stronger orienting response to direct versus averted gaze in typically developing (N?=?17) and developmentally delayed (N?=?16) children but not in children with ASD (N?=?12). The lack of enhanced orienting response to direct gaze in the ASD group was not caused by a lack of looking at the eye region, as confirmed by eye tracking. The results suggest that direct gaze is not a socially salient, attention-grabbing signal for low-functioning children with ASD.

The influence of emotional stimuli on attention orienting and inhibitory control in pediatric anxiety / Sven C. MUELLER in Journal of Child Psychology and Psychiatry, 53-8 (August 2012)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 53-8 (August 2012) . - p.856-863 Titre : The influence of emotional stimuli on attention orienting and inhibitory control in pediatric anxiety Type de document : Texte imprimé et/ou numérique Auteurs : Sven C.

While recent studies conducted with high-trait anxious adults have employed novel emotion-modified antisaccade tasks to examine the influence of emotional information on orienting and inhibition, similar studies have yet to be conducted in youths. Methods:  Participants were 22 children/adolescents diagnosed with an anxiety disorder, and 22 age-matched healthy comparison youths. Participants completed an emotion-modified antisaccade task that was similar to those used in studies of high-trait anxious adults. This task probed the influence of abruptly appearing neutral, happy, angry, or fear stimuli on orienting (prosaccade) or inhibitory (antisaccade) responses. Results:  Anxious compared to healthy children showed facilitated orienting toward angry stimuli. With respect to inhibitory processes, threat-related information improved antisaccade accuracy in healthy but not anxious youth. These findings were not linked to individual levels of reported anxiety or specific anxiety disorders. Conclusions:  Findings suggest that anxious relative to healthy children manifest enhanced orienting toward threat-related stimuli. In addition, the current findings suggest that threat may modulate inhibitory control during adolescent development.

Autistic Traits and Symptoms of Social Anxiety are Differentially Related to Attention to Others' Eyes in Social Anxiety Disorder / J. L. KLEBERG in Journal of Autism and Developmental Disorders, 47-12 (December 2017)

Gaze avoidance has been linked to both SAD and ASD, but little is known about differences in social attention between the two conditions. We studied eye movements in a group of treatment-seeking adolescents with SAD (N = 25), assessing SAD and ASD dimensionally. The results indicated a double dissociation between two measures of social attention and the two symptom dimensions. Controlling for social anxiety, elevated autistic traits were associated with delayed orienting to eyes presented among distractors. In contrast, elevated social anxiety levels were associated with faster orienting away from the eyes, when controlling for autistic traits. This distinction deepens our understanding of ASD and SAD.

Reduced visual disengagement but intact phasic alerting in young children with autism / Johan Lundin KLEBERG in Autism Research, 10-3 (March 2017)  

Public ISBD [article]  inAutism Research > 10-3 (March 2017) . - p.539-545 Titre : Reduced visual disengagement but intact phasic alerting in young children with autism Type de document : Texte imprimé et/ou numérique Auteurs : Johan Lundin KLEBERG, Auteur ; Emilia THORUP, Auteur ; Terje FALCK-YTTER, Auteur Article en page(s) : p.539-545 Langues : Anglais (eng) Mots-clés : autism  attention  gap effect  visual disengagement  alerting  orienting  arousal Index. décimale : PER Périodiques Résumé : Children with autism may have difficulties with visual disengagement—that is, inhibiting current fixations and orienting to new stimuli in the periphery. These difficulties may limit these children's ability to flexibly monitor the environment, regulate their internal states, and interact with others. In typical development, visual disengagement is influenced by a phasic alerting network that increases the processing speed of the visual system after salient events. The role of the phasic alerting effect in the putative atypical disengagement performance in autism spectrum disorder (ASD) is not known. Here, we compared visual disengagement in six-year-old children with autism (N?=?18) and typically developing children (N?=?17) matched for age and nonverbal IQ. We manipulated phasic alerting during a visual disengagement task by adding spatially nonpredictive sounds shortly before the onset of the visual peripheral targets. Children with ASD showed evidence of delayed disengagement compared to the control group. Sounds facilitated visual disengagement similarly in both groups, suggesting typical modulation by phasic alerting in ASD in the context of this task. These results support the view that atypical visual disengagement in ASD is related to other factors than atypicalities in the alerting network.

Social-Emotional Inhibition of Return in Children with Autism Spectrum Disorder Versus Typical Development / Ligia ANTEZANA in Journal of Autism and Developmental Disorders, 46-4 (April 2016)

Children with ASD do not reliably demonstrate this bias, and the role of attention orienting has not been well studied. We examined attention orienting via the inhibition of return (IOR) mechanism in a spatial cueing task using social-emotional cues; we studied 8- to 17-year-old children with ASD (n = 41) and typically developing controls (TDC) (n = 25). The ASD group exhibited a significantly stronger IOR effect than the TDC group, and the IOR effect correlated positively with social impairments but was unrelated to co-occurring ADHD or anxiety symptoms. The results provide evidence of an early altered attention mechanism that is associated with to core social deficits in ASD.
