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…

In two studies, we used the Gottschaldt's Hidden Figure Test (GHFT) for assessing figure disembedding ability in children aged 7-11. Study 1 demonstrated in a large sample of typically developing children that GHFT accuracy and time scores differed across age groups, without sex and socioeconomic differences. Thus, we provided normative data only…

Schulz, S. E.; Stevenson, R. A. – Journal of Autism and Developmental Disorders, 2022
Sensory issues are highly prevalent in autism and previous findings support a relationship between questionnaires of sensitivity and autistic symptoms and traits, whereas studies that examine this relationship through behavioural assessments of sensitivity are less consistent. The current study explores these differences and suggests that…

Coburn, Kelly L.; Williams, Diane L. – Journal of Autism and Developmental Disorders, 2022
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…

Weber, Stephanie; Falter-Wagner, Christine; Stöttinger, Elisabeth – Journal of Autism and Developmental Disorders, 2021
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…

Montgomery, Lewis; Chondrogianni, Vicky; Fletcher-Watson, Sue; Rabagliati, Hugh; Sorace, Antonella; Davis, Rachael – Journal of Autism and Developmental Disorders, 2022
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…

Turbett, Kaitlyn; Jeffery, Linda; Bell, Jason; Burton, Jessamy; Palermo, Romina – Journal of Autism and Developmental Disorders, 2022
Face recognition difficulties are common in autism and could be a consequence of perceptual atypicalities that disrupt the ability to integrate current and prior information. We tested this theory by measuring the strength of serial dependence for faces (i.e. how likely is it that current perception of a face is biased towards a previously seen…

Feldman, Jacob I.; Conrad, Julie G.; Kuang, Wayne; Tu, Alexander; Liu, Yupeng; Simon, David M.; Wallace, Mark T.; Woynaroski, Tiffany G. – Journal of Autism and Developmental Disorders, 2022
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…

Tortelli, Chiara; Turi, Marco; Burr, David C.; Binda, Paola – Journal of Autism and Developmental Disorders, 2021
We measured the pupil response to a light stimulus subject to a size illusion and found that stimuli perceived as larger evoke a stronger pupillary response. The size illusion depends on combining retinal signals with contextual 3D information; contextual processing is thought to vary across individuals, being weaker in individuals with stronger…

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…

The Relation between Autistic Traits, the Degree of Synaesthesia, and Local/Global Visual Perception
Burghoorn, Floor; Dingemanse, Mark; van Lier, Rob; van Leeuwen, Tessa M. – Journal of Autism and Developmental Disorders, 2020
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…

Tillmann, Julian; Tuomainen, Jyrki; Swettenham, John – Journal of Autism and Developmental Disorders, 2021
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…

Ramos-Sánchez, Carlos Pelayo; Kortekaas, Dianne; Van Biesen, Debbie; Vancampfort, Davy; Van Damme, Tine – Journal of Autism and Developmental Disorders, 2022
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…

Ganglmayer, Kerstin; Schuwerk, Tobias; Sodian, Beate; Paulus, Markus – Journal of Autism and Developmental Disorders, 2020
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…

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, 2020
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…
