Gaze Following in Children with Autism: Do High Interest Objects Boost Performance? / Emilia THORUP in Journal of Autism and Developmental Disorders, 47-3 (March 2017)

It has previously been found that autistic children differentiate less between an object another person attends to and unattended objects in terms of this measure. Less differentiation between attended and unattended objects in ASD as compared to control children was found in a baseline condition, but not in the high interest condition. However, typically developing children differentiated less between attended and unattended objects in the high interest condition than in the baseline condition, possibly reflecting reduced influence of gaze cues on object processing when objects themselves are highly interesting.

Increased pupil dilation to happy faces in children with hyperactive/impulsive symptoms of ADHD / Johan Lundin KLEBERG in Development and Psychopathology, 33-3 (August 2021)  

Public ISBD [article]  inDevelopment and Psychopathology > 33-3 (August 2021) . - p.767-777 Titre : Increased pupil dilation to happy faces in children with hyperactive/impulsive symptoms of ADHD Type de document : Texte imprimé et/ou numérique Auteurs : Johan Lundin KLEBERG, Auteur ; Matilda A. FRICK, Auteur ; Karin C. BROCKI, Auteur Article en page(s) : p.767-777 Langues : Anglais (eng) Mots-clés : arousal  attention-deficit/hyperactivity disorder (ADHD)  face perception  positive emotionality  pupil dilation Index. décimale : PER Périodiques Résumé : Attention-deficit/hyperactivity disorder (ADHD) is associated with disrupted emotional processes including impaired regulation of approach behavior and positive affect, irritability, and anger. Enhanced reactivity to emotional cues may be an underlying process. Pupil dilation is an indirect index of arousal, modulated by the autonomic nervous system and activity in the locus coeruleus-noradrenergic system. In the current study, pupil dilation was recorded while 8- to 12- year old children (n = 71, 26 with a diagnosis of ADHD and 45 typically developing), viewed images of emotional faces. Parent-rated hyperactive/impulsive symptoms were uniquely linked to higher pupil dilation to happy, but not fearful, angry, or neutral faces. This was not explained by comorbid externalizing symptoms. Together, these results suggest that hyperactive/impulsive symptoms are associated with hyperresponsiveness to approach-related emotional cues across a wide range of symptom severity.

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.

Williams syndrome: reduced orienting to other?s eyes in a hypersocial phenotype / Johan Lundin KLEBERG in Journal of Autism and Developmental Disorders, 53-7 (July 2023)

Attention to others' eyes is crucial for social understanding. Orienting to, and from other?s eyes was studied in WS (n?=?37, mean age?=?23, age range 9-53). The WS group was compared to a typically developing comparison participants (n?=?167) in stratified age groups from infancy to adulthood. Typically developing children and adults were quicker and more likely to orient to eyes than the mouth. This bias was absent in WS. The WS group had reduced peak saccadic velocities, indicating hypo-arousal. The current study indicates reduced orienting to others' eyes in WS, which may affect social interaction skills.
