We aimed to identify unique constellations of sensory phenotypes for genetic etiologies associated with diagnoses of autism spectrum disorder (ASD) and intellectual disability (ID). Caregivers reported on sensory behaviors via the Sensory Profile for 290 participants (younger than 25 years of age) with ASD and/or ID diagnoses, of which…

Yang, Han-Xue; Zhou, Han-Yu; Zheng, Hong; Wang, Yi; Wang, Yan-Yu; Lui, Simon S. Y.; Chan, Raymond C. K. – Journal of Autism and Developmental Disorders, 2022
Interoceptive accuracy has been widely measured using the Heartbeat Tracking Test (HTT). We devised the novel paradigm of Interoception-Exteroception Synchronicity Judgement (IESJ) task to assess participants' interoceptive accuracy, exteroceptive accuracy, and the balancing score which reflected the ability to allocate attentions between…

Traynor, J. M.; Gough, A.; Duku, E.; Shore, D. I.; Hall, G. B. C. – Journal of Autism and Developmental Disorders, 2019
The social communicative deficits and repetitive behaviours seen in Autism Spectrum Disorder (ASD) may be affected by altered stimulus salience and reward attribution. The present study used eye tracking and a behavioural measure to index effort expenditure, arousal, and attention, during viewing of images depicting social scenes and…

The Adult Repetitive Behaviours Questionnaire-2 (RBQ-2A): A Self-Report Measure of Restricted and Repetitive Behaviours
Peer reviewed Peer reviewed

Barrett, Sarah L.; Uljarevic, Mirko; Baker, Emma K.; Richdale, Amanda L.; Jones, Catherine R. G.; Leekam, Susan R. – Journal of Autism and Developmental Disorders, 2015
In two studies we developed and tested a new self-report measure of restricted and repetitive behaviours (RRB) suitable for adults. In Study 1, The Repetitive Behaviours Questionnaire-2 for adults (RBQ-2A) was completed by a sample of 163 neurotypical adults. Principal components analysis revealed two components: Repetitive Motor Behaviours and…

Attention to Eyes and Mouth in High-Functioning Children with Autism
Peer reviewed Peer reviewed

Bar-Haim, Yair; Shulman, Cory; Lamy, Dominique; Reuveni, Arnon – Journal of Autism and Developmental Disorders, 2006
In the present study, we used a probe-detection task to compare attentional allocation to the eyes versus mouth regions of the face in high-functioning boys with autism relative to normal control boys matched for chronological age and IQs. We found that with upright faces, children from both groups attended more to the eyes region than to the…

A Comparative Study of Development and Symptoms among Disintegrative Psychosis and Infantile Autism with and without Speech Loss.
Peer reviewed Peer reviewed
Kurita, Hiroshi; And Others – Journal of Autism and Developmental Disorders, 1992
Eighteen cases of disintegrative psychosis (DP) were compared with 52 cases of infantile autism (IA) with speech loss and 145 IA cases without speech loss. DP cases showed clearer regression after more satisfactory development than the IA cases with speech loss, and by age seven were more severely retarded but similar in autistic symptomatology to…
