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 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.

Altered gaze following during live interaction in infants at risk for autism: an eye tracking study / Emilia THORUP in Molecular Autism, 7 (2016)  

Public ISBD [article]  inMolecular Autism > 7 (2016) . - 12 p. Titre : Altered gaze following during live interaction in infants at risk for autism: an eye tracking study Type de document : texte imprimé Auteurs : Emilia THORUP, Auteur ; P. NYSTROM, Auteur ; G. GREDEBACK, Auteur ; Sven BÖLTE, Auteur ; Terje FALCK-YTTER, Auteur Article en page(s) : 12 p. Langues : Anglais (eng) Mots-clés : Attention/physiology  Autism Spectrum Disorder/diagnosis/epidemiology/physiopathology  Cues  Early Diagnosis  Eye Movements  Family Health  Female  Fixation, Ocular/physiology  Head Movements  Humans  Imitative Behavior/physiology  Infant  Male  Pursuit, Smooth/physiology  Risk  Single-Blind Method  Social Behavior  Social Perception  Autism  Communication  Early development  Gaze following  Joint attention  Neurodevelopmental disorders  Social cognition  Younger siblings Index. décimale : PER Périodiques Résumé : BACKGROUND: The ability to follow gaze is an important prerequisite for joint attention, which is often compromised in children with autism spectrum disorder (ASD). The direction of both the head and eyes provides cues to other people's attention direction, but previous studies have not separated these factors and their relation to ASD susceptibility. Development of gaze following typically occurs before ASD diagnosis is possible, and studies of high-risk populations are therefore important. METHODS: Eye tracking was used to assess gaze following during interaction in a group of 10-month-old infants at high familial risk for ASD (high-risk group) as well as a group of infants with no family history of ASD (low-risk group). The infants watched an experimenter gaze at objects in the periphery. Performance was compared across two conditions: one in which the experimenter moved both the eyes and head toward the objects (Eyes and Head condition) and one that involved movement of the eyes only (Eyes Only condition). RESULTS: A group by condition interaction effect was found. Specifically, whereas gaze following accuracy was comparable across the two conditions in the low-risk group, infants in the high-risk group were more likely to follow gaze in the Eyes and Head condition than in the Eyes Only condition. CONCLUSIONS: In an ecologically valid social situation, responses to basic non-verbal orienting cues were found to be altered in infants at risk for ASD. The results indicate that infants at risk for ASD may rely disproportionally on information from the head when following gaze and point to the importance of separating information from the eyes and the head when studying social perception in ASD.

Effects of Observing Eye Contact on Gaze Following in High-Functioning Autism / Anne BÖCKLER in Journal of Autism and Developmental Disorders, 44-7 (July 2014)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 44-7 (July 2014) . - p.1651-1658 Titre : Effects of Observing Eye Contact on Gaze Following in High-Functioning Autism Type de document : texte imprimé Auteurs : Anne BÖCKLER, Auteur ; Bert TIMMERMANS, Auteur ; Natalie SEBANZ, Auteur ; Kai VOGELEY, Auteur ; Leonhard SCHILBACH, Auteur Article en page(s) : p.1651-1658 Langues : Anglais (eng) Mots-clés : Gaze following  Joint attention  Social cognition  High-functioning autism Index. décimale : PER Périodiques Résumé : Observing eye contact between others enhances the tendency to subsequently follow their gaze and has been suggested to function as a social signal that adds meaning to an upcoming action or event. The present study investigated effects of observed eye contact in high-functioning autism (HFA). Two faces on a screen either looked at or away from each other before providing congruent or incongruent gaze cues to one of two target locations. In contrast to control participants, HFA participants did not depict enhanced gaze following after observing eye contact. Individuals with autism, hence, do not seem to process observed mutual gaze as a social signal indicating the relevance of upcoming (gaze) behaviour. This may be based on the reduced tendency of individuals with HFA to engage in social gaze behavior themselves, and might underlie some of the characteristic deficiencies in social communicative behaviour in autism.

Parent-mediated intervention in infants with an elevated likelihood for autism reduces dwell time during a gaze-following task / Rachael BEDFORD in Autism Research, 17-11 (November 2024)

The current study tests the impact of the Intervention with the British Autism Study of Infant Siblings?Video Interaction for Promoting Positive Parenting (iBASIS-VIPP) on an eye-tracking measure of social attention: dwell time to the referred object in a gaze following task. The original two-site, two-arm, assessor-blinded randomized controlled trial (RCT) of this intervention to increase parental awareness, and responsiveness to their infant, was run with infants who have an elevated familial likelihood for autism (EL). Fifty-four EL infants (28 iBASIS-VIPP intervention, 26 no intervention) were enrolled, and the intervention took place between 9 months (baseline) and 15 months (endpoint), with gaze following behavior measured at 15 months. Secondary intention to treat (ITT) analysis showed that the intervention was associated with significantly reduced dwell time to the referent of another person's gaze (? 0.32, SE 0.14, p 0.03) at 15-month treatment endpoint. Given the established link between gaze following and language, the results are considered in the context of a previously reported, non-significant and transient trend toward lower language scores at the treatment endpoint (Green et al. (2015) The Lancet Psychiatry, 2(2), 133 140). Future intervention trials should aim to include experimental cognitive measures, alongside behavioral measures, to investigate mechanisms associated with intervention effects.

Precursors to Social and Communication Difficulties in Infants At-Risk for Autism: Gaze Following and Attentional Engagement / Rachael BEDFORD in Journal of Autism and Developmental Disorders, 42-10 (October 2012)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 42-10 (October 2012) . - p.2208-2218 Titre : Precursors to Social and Communication Difficulties in Infants At-Risk for Autism: Gaze Following and Attentional Engagement Type de document : texte imprimé Auteurs : Rachael BEDFORD, Auteur ; Mayada ELSABBAGH, Auteur ; Teodora GLIGA, Auteur ; Andrew PICKLES, Auteur ; Atsushi SENJU, Auteur ; Tony CHARMAN, Auteur ; Mark H.

We employed eye-tracking to record gaze following longitudinally in infants with and without a family history of autism spectrum disorder (ASD) at 7 and 13 months. No group difference was found between at-risk and low-risk infants in gaze following behaviour at either age. However, despite following gaze successfully at 13 months, at-risk infants with later emerging socio-communication difficulties (both those with ASD and atypical development at 36 months of age) allocated less attention to the congruent object compared to typically developing at-risk siblings and low-risk controls. The findings suggest that the subtle emergence of difficulties in JA in infancy may be related to ASD and other atypical outcomes.
