Girard, Dominique; Courchesne, Valérie; Cimon-Paquet, Catherine; Jacques, Claudine; Soulières, Isabelle – Autism: The International Journal of Research and Practice, 2023
The current prospective cohort study investigated whether early perceptual abilities, measured at preschool age, could predict later intellectual abilities at school age in a group of 41 autistic (9 girls, 32 boys) and 57 neurotypical children (29 girls, 28 boys). More than 80% of the autistic children were considered minimally verbal.…

Donkers, Franc C. L.; Carlson, Mike; Schipul, Sarah E.; Belger, Aysenil; Baranek, Grace T. – Autism: The International Journal of Research and Practice, 2020
Atypical sensory response patterns are common in children with autism and developmental delay. Expanding on previous work, this observational electroencephalogram study assessed auditory event-related potentials and their associations with clinically evaluated sensory response patterns in children with autism spectrum disorder (n = 28),…

Brinkert, Jana; Remington, Anna – Autism: The International Journal of Research and Practice, 2020
Recent studies highlighted that autistic individuals show increased perceptual capacity -- the ability to process more information at any one time. This study examined whether there is a link between this increased perceptual capacity and the sensory hypersensitivity that many autistic people experience on a daily basis. In total, 38 autistic and…

Stewart, Mary E.; Petrou, Alexandra M.; Ota, Mitsuhiko – Journal of Autism and Developmental Disorders, 2018
This study tested whether individuals with autism spectrum conditions (n = 23) show enhanced discrimination of acoustic differences that signal a linguistic contrast (i.e., /g/ versus /k/ as in "goat" and "coat") and whether they process such differences in a less categorical fashion as compared with 23 IQ-matched typically…

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…

Bolte, Sven; Duketis, Eftichia; Poustka, Fritz; Holtmann, Martin – Autism: The International Journal of Research and Practice, 2011
Despite the skewed sex ratio, few studies have addressed possible cognitive sex differences in autism spectrum disorders (ASDs). This study compared visual attention to detail (ATTD) and selected executive functions (EF) in 35 males and 21 females with higher-functioning ASD and unaffected sibling controls. Females with ASD outperformed males on…
