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…

Ni, Pingping; Xue, Lingfeng; Cai, Jiajing; Wen, Minjie; He, Jie – Autism: The International Journal of Research and Practice, 2021
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…

Nyström, Pär; Jones, Emily; Darki, Fahimeh; Bölte, Sven; Falck-Ytter, Terje – Journal of Autism and Developmental Disorders, 2021
Research indicates that individuals with autism spectrum disorder (ASD) are superior at local processing while the integration of local features to global percepts is reduced. Here, we compared infants at familiar risk for ASD to typically developing infants in terms of global coherence processing at 5 months of age, using steady state visually…

Guy, Jacalyn; Mottron, Laurent; Berthiaume, Claude; Bertone, Armando – Journal of Autism and Developmental Disorders, 2019
Individuals with autism spectrum disorder (ASD) demonstrate superior performances on visuo-spatial tasks emphasizing local information processing; however, findings from studies involving hierarchical stimuli are inconsistent. Wide age ranges and group means complicate their interpretability. Children and adolescents with and without ASD completed…

Tse, Venus W. S.; Crabtree, Jason; Islam, Shamsun; Stott, Joshua – Journal of Autism and Developmental Disorders, 2019
This study aimed to compare cognitive and memory abilities between older adults with and without autism over the age of 50. Twenty-eight individuals with autism and 29 typically developing (TD) older adults took part in the current study. Participants' cognitive and memory abilities were assessed by WAIS-IV and WMS-IV. Older autistic adults were…

van Laarhoven, Thijs; Stekelenburg, Jeroen J.; Eussen, Mart L. J. M.; Vroomen, Jean – Autism: The International Journal of Research and Practice, 2020
Autism spectrum disorder is a pervasive neurodevelopmental disorder that has been linked to a range of perceptual processing alterations, including hypo- and hyperresponsiveness to sensory stimulation. A recently proposed theory that attempts to account for these symptoms, states that autistic individuals have a decreased ability to anticipate…

Keehn, Brandon; Westerfield, Marissa; Townsend, Jeanne – Journal of Autism and Developmental Disorders, 2019
This study investigates how task-irrelevant auditory information is processed in children with autism spectrum disorder (ASD). Eighteen children with ASD and 19 age- and IQ-matched typically developing (TD) children were presented with semantically-congruent and incongruent picture-sound pairs, and in separate tasks were instructed to attend to…

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…

Van der Hallen, Ruth; Evers, Kris; Boets, Bart; Steyaert, Jean; Noens, Ilse; Wagemans, Johan – Journal of Autism and Developmental Disorders, 2016
Visual search has been used extensively to investigate differences in mid-level visual processing between individuals with ASD and TD individuals. The current study employed two visual search paradigms with Gaborized stimuli to assess the impact of task distractors (Experiment 1) and task instruction (Experiment 2) on local-global visual…

Vanmarcke, Steven; Noens, Ilse; Steyaert, Jean; Wagemans, Johan – Journal of Autism and Developmental Disorders, 2017
While most typically developing (TD) participants have a coarse-to-fine processing style, people with autism spectrum disorder (ASD) seem to be less globally and more locally biased when processing visual information. The stimulus-specific spatial frequency content might be directly relevant to determine this temporal hierarchy of visual…

Stevenson, Ryan A.; Segers, Magali; Ncube, Busisiwe L.; Black, Karen R.; Bebko, James M.; Ferber, Susanne; Barense, Morgan D. – Autism: The International Journal of Research and Practice, 2018
It has been recently theorized that atypical sensory processing in autism relates to difficulties in social communication. Through a series of tasks concurrently assessing multisensory temporal processes, multisensory integration and speech perception in 76 children with and without autism, we provide the first behavioral evidence of such a link.…

Carter Leno, Virginia; Vitoratou, Silia; Kent, Rachel; Charman, Tony; Chandler, Susie; Jones, Catherine RG; Happé, Francesca; Baird, Gillian; Pickles, Andrew; Simonoff, Emily – Autism: The International Journal of Research and Practice, 2019
Many young people with autism spectrum disorder display 'challenging behaviours', characterised by externalising behaviour and self-injurious behaviours. These behaviours can have a negative impact on a young person's well-being, family environment and educational achievement. However, the development of effective interventions requires greater…

Vogan, Vanessa M.; Morgan, Benjamin R.; Smith, Mary Lou; Taylor, Margot J. – Autism: The International Journal of Research and Practice, 2019
This study examined functional changes longitudinally over 2 years in neural correlates associated with working memory in youth with and without autism spectrum disorder, and the impact of increasing cognitive load. We used functional magnetic resonance imaging and a visuo-spatial 1-back task with four levels of difficulty. A total of 14 children…

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…

Luckhardt, Christina; Kröger, Anne; Cholemkery, Hannah; Bender, Stephan; Freitag, Christine M. – Journal of Autism and Developmental Disorders, 2017
The underlying neural mechanisms of implicit and explicit facial emotion recognition (FER) were studied in children and adolescents with autism spectrum disorder (ASD) compared to matched typically developing controls (TDC). EEG was obtained from N = 21 ASD and N = 16 TDC. Task performance, visual (P100, N170) and cognitive (late positive…
