It has been argued that autistic individuals have difficulties with face memory but typical face perception. However, only one previous study has examined both face memory and face perception in the same individuals, and this study was conducted with a small group of autistic children. Here, face recognition was examined with a group of autistic…

Despite challenges in social communication skills people with ASD often display strengths in visual processing. Aerial photography analysis is an occupation reliant on strong visual processing skills that matches this unique profile. We investigated basic-vision and "real-life" visual tasks in 20 cognitively-able young adults with ASD…

Challenges to verbal encoding may affect the ability of autistic individuals to express their ideas. Therefore, visuospatial expression may represent a person's knowledge and skills more accurately than spoken language. To test this hypothesis, we asked seven autistic adults to linguistically retell and visuospatially reenact several animated…

Individuals with Autism Spectrum Disorder (ASD) can struggle with visual updating. In a previous picture morphing study (Burnett and Jellema 2012) adults with ASD recognized the second picture significantly later when seeing one picture gradually changing into another. The aim of the current study was to test whether this previously reported…

One factor that may influence how executive functions develop is exposure to more than one language in childhood. This study explored the impact of bilingualism on inhibitory control in autistic (n = 38) and non-autistic children (n = 51). Bilingualism was measured on a continuum of exposure to investigate the effects of language environment on…

Children with autism show alterations in multisensory integration that have been theoretically and empirically linked with the core and related features of autism. It is unclear, however, to what extent multisensory integration maps onto features of autism within children with and without autism. This study, thus, evaluates relations between…

Individuals with Autism Spectrum Disorder (ASD) are thought to under-rely on prior knowledge in perceptual decision-making. This study examined whether this applies to decisions of attention allocation, of relevance for 'predictive-coding' accounts of ASD. In a visual search task, a salient but task-irrelevant distractor appeared with higher…

Synaesthesia is highly prevalent in autism spectrum disorder. We assessed the relation between the degree of autistic traits (Autism Spectrum Quotient, AQ) and the degree of synaesthesia in a neurotypical population, and hypothesized both are related to a local bias in visual perception. A positive correlation between total AQ scores and the…

This study examined the effect of increasing visual perceptual load on auditory awareness for social and non-social stimuli in adolescents with autism spectrum disorder (ASD, n = 63) and typically developing (TD, n = 62) adolescents. Using an inattentional deafness paradigm, a socially meaningful ('Hi') or a non-social (neutral tone) critical…

It is still unknown whether visual illusion can bias motor performance in Autism Spectrum Disorders (ASD) individuals. The present study aimed to evaluate the effect of visual illusion on performance in children with ASD in a far-aiming skill. In a within-subject design, participants (n = 20, IQ > 70, mean age: 10.15) performed golf putting…

This study explored the association between intelligence and motor skills in children with ASD after controlling for Attention Deficit and Hyperactivity Disorder (ADHD) and the associations between motor impairment and intellectual disability (ID) in this population. In total, 120 children with ASD (3-16 years; 81.7% boys) completed a standardized…

An action's end state can be anticipated by considering the agent's goal, or simply by projecting the movement trajectory. Theories suggest that individuals with autism spectrum condition (ASC) have difficulties anticipating other's goal-directed actions, caused by an impairment using prior information. We examined whether children, adolescents…

Visual information is crucial for postural control. Visual processing in children with autism spectrum disorder (ASD) was hypothesized to be less efficient and thus they would display a less stable standing posture than typically developing children. The present study compared the static standing responses and attentional demands of 15 children…

Visual perspective-taking is the ability to perceive the world from another person's perspective, and research on visual perspective-taking ability in children with autism spectrum conditions yielded inconsistent results. To solve a visual perspective-taking task, people can mentally rotate themselves to another person's location (embodied…

We assessed the association between dynamic changes in pupil response in the context of visual perception and quantitative measures of the autism phenotype in healthy adults. Using Navon stimuli in a task-switching paradigm, participants were instructed to identify global or local information based on a cue. Multiple pupil response trajectories…
