Cañigueral, Roser; Hamilton, Antonia F. de C. – Journal of Autism and Developmental Disorders, 2019
Autistic people process gaze differently than typical people, but it is not yet clear if these differences lie in the processing of eye-shapes or the belief in whether others can see (perceptual mentalizing). We aimed to investigate whether these two models of gaze processing modulate social seeking in typical and autistic adults. We measured…

Carpenter, Katie L.; Williams, David M.; Nicholson, Toby – Journal of Autism and Developmental Disorders, 2019
It has been argued that metacognition and mindreading rely on the same cognitive processes (Carruthers in The opacity of mind: an integrative theory of self-knowledge, Oxford University Press, Oxford, 2011). It is widely accepted that mindreading is diminished among individuals diagnosed with autism (Brunsdon and Happé in Autism 18(1):17-30,…

Nicholson, Toby; Williams, David; Carpenter, Katie; Kallitsounaki, Aimilia – Journal of Autism and Developmental Disorders, 2019
Interoception (the ability to sense what's going on inside one's body) is considered integral to many higher-order cognitive processes. Some have speculated that impaired interoception may underpin some features of ASD. Yet, in Experiment 1, we found no evidence of a between-group difference in either cardiac or respiratory interoceptive accuracy…

Lim, Yi Huey; Lee, Hoe C.; Falkmer, Torbjörn; Allison, Garry T.; Tan, Tele; Lee, Wee Lih; Morris, Susan L. – Journal of Autism and Developmental Disorders, 2019
Sensory processing difficulties affect the development of sensorimotor skills in individuals with autism spectrum disorder (ASD). However, the effect of sensory information on postural control is unclear in the ASD adult population. The present study examined the effect of visual information on postural control as well as the attentional demands…

Cole, Eleanor J.; Slocombe, Katie E.; Barraclough, Nick E. – Journal of Autism and Developmental Disorders, 2018
Previous research suggests that Autism Spectrum Disorder (ASD) might be associated with impairments on implicit but not explicit mentalizing tasks. However, such comparisons are made difficult by the heterogeneity of stimuli and the techniques used to measure mentalizing capabilities. We tested the abilities of 34 individuals (17 with ASD) to…

Goh, Kwang Leng; Morris, Susan; Parsons, Richard; Ring, Alexander; Tan, Tele – Journal of Autism and Developmental Disorders, 2018
Autism is associated with differences in sensory processing and motor coordination. Evidence from electroencephalography suggests individual perturbation evoked response (PER) components represent specific aspects of postural disturbance processing; P1 reflects the detection and N1 reflects the evaluation of postural instability. Despite the…

Ring, Melanie; Gaigg, Sebastian B.; Altgassen, Mareike; Barr, Peter; Bowler, Dermot M. – Journal of Autism and Developmental Disorders, 2018
Individuals with autism spectrum disorder (ASD) present difficulties in forming relations among items and context. This capacity for relational binding is also involved in spatial navigation and research on this topic in ASD is scarce and inconclusive. Using a computerised version of the Morris Water Maze task, ASD participants showed particular…

Cole, Eleanor J.; Barraclough, Nick E.; Enticott, Peter G. – Journal of Autism and Developmental Disorders, 2018
ASD is associated with mentalizing deficits that may correspond with atypical mirror system (MS) activation. We investigated MS activity in adults with and without ASD when inferring others' intentions using TMS-induced motor evoked potentials (MEPs) and mu suppression measured by EEG. Autistic traits were measured for all participants. Our EEG…

Haigh, Sarah M.; Walsh, Jennifer A.; Mazefsky, Carla A.; Minshew, Nancy J.; Eack, Shaun M. – Journal of Autism and Developmental Disorders, 2018
Autism spectrum disorder (ASD) is characterized by a variety of social and non-social behavioral deficits. One potential mechanism that could unify this diverse profile of behaviors is slower processing speed. Seventy-six high-functioning adults with ASD were compared to 64 matched controls on standardized measures of processing speed.…

Booth, Rhonda D. L.; Happé, Francesca G. E. – Journal of Autism and Developmental Disorders, 2018
Frith's original notion of 'weak central coherence' suggested that increased local processing in autism spectrum disorder (ASD) resulted from reduced global processing. More recent accounts have emphasised superior local perception and suggested intact global integration. However, tasks often place local and global processing in direct trade-off,…

Mul, Cari-lène; Stagg, Steven D.; Herbelin, Bruno; Aspell, Jane E. – Journal of Autism and Developmental Disorders, 2018
Following recent evidence for a link between interoception, emotion and empathy, we investigated relationships between these factors in autism spectrum disorder (ASD). 26 adults with ASD and 26 healthy participants completed tasks measuring interoception, alexithymia and empathy. ASD participants with alexithymia demonstrated lower cognitive and…

Gosling, Corentin J.; Moutier, Sylvain – Journal of Autism and Developmental Disorders, 2018
Risk-aversion and rationality have both been highlighted as core features of decision making in individuals with Autism Spectrum Disorders (ASD). This study tested whether risk-aversion is related to rational decision-making in ASD individuals. ASD and matched control adults completed a decision-making task that discriminated between the use of…

Reed, Phil – Journal of Autism and Developmental Disorders, 2017
The relationships of autism quotient (AQ), systematizing (SQ), and empathizing (EQ), with over-selectivity were explored to assess whether over-selectivity is implicated in complex social skills, which has been assumed, but not experimentally examined. Eighty participants (aged 18-60) were trained on a simultaneous discrimination task (AB+CD-),…

Powell, Patrick S.; Klinger, Laura G.; Klinger, Mark R. – Journal of Autism and Developmental Disorders, 2017
Little is known about age-related cognitive differences in autism spectrum disorder (ASD). However, given the overlap in cognitive impairments in ASD to those seen in typical aging, it is possible that adults with ASD will face even greater cognitive difficulties as they age. The current study used a cross-sectional design to examine age-related…

English, Michael C. W.; Maybery, Murray T.; Visser, Troy A. W. – Journal of Autism and Developmental Disorders, 2017
Previous work shows that doing a continuous performance task (CPT) shifts attentional biases in neurotypical individuals towards global aspects of hierarchical Navon figures by selectively activating right hemisphere regions associated with global processing. The present study examines whether CPT can induce similar modulations of attention in…
