Brief Report: Lack of Processing Bias for the Objects Other People Attend to in 3-Year-Olds with Autism / Terje FALCK-YTTER in Journal of Autism and Developmental Disorders, 45-6 (June 2015)

Functional gaze following involves saccading towards the attended rather than unattended targets (accuracy) as well as a subsequent processing bias for attended objects. Using non-invasive eye tracking technology, we show that gaze following accuracy is intact in intellectually low-functioning 3-year-olds with ASD. However, analyses of the duration of first fixations at the objects in the scene revealed markedly weaker initial processing bias for attended objects in children with ASD compared to children with typical development and non-autistic children with developmental delays. Limited processing bias for the objects other people attend to may negatively affect learning opportunities in ASD.

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)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 47-3 (March 2017) . - p.626-635 Titre : Gaze Following in Children with Autism: Do High Interest Objects Boost Performance? Type de document : Texte imprimé et/ou numérique Auteurs : Emilia THORUP, Auteur ; Johan Lundin KLEBERG, Auteur ; Terje FALCK-YTTER, Auteur Article en page(s) : p.626-635 Langues : Anglais (eng) Mots-clés : Gaze following  Joint attention  Circumscribed interests  Communication  Social cognition Index. décimale : PER Périodiques Résumé : This study tested whether including objects perceived as highly interesting by children with autism during a gaze following task would result in increased first fixation durations on the target objects. 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.

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.

Visual orienting in children with autism: Hyper-responsiveness to human eyes presented after a brief alerting audio-signal, but hyporesponsiveness to eyes presented without sound / Johan LUNDIN KLEBERG in Autism Research, 10-2 (February 2017)  

Public ISBD [article]  inAutism Research > 10-2 (February 2017) . - p.246-250 Titre : Visual orienting in children with autism: Hyper-responsiveness to human eyes presented after a brief alerting audio-signal, but hyporesponsiveness to eyes presented without sound 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.246-250 Langues : Anglais (eng) Mots-clés : Autism  social orienting  eye tracking  phasic alerting  arousal  face perception Index. décimale : PER Périodiques Résumé : Autism Spectrum Disorder (ASD) has been associated with reduced orienting to social stimuli such as eyes, but the results are inconsistent. It is not known whether atypicalities in phasic alerting could play a role in putative altered social orienting in ASD. Here, we show that in unisensory (visual) trials, children with ASD are slower to orient to eyes (among distractors) than controls matched for age, sex, and nonverbal IQ. However, in another condition where a brief spatially nonpredictive sound was presented just before the visual targets, this group effect was reversed. Our results indicate that orienting to social versus nonsocial stimuli is differently modulated by phasic alerting mechanisms in young children with ASD.
