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…

Tillmann, Julian; Swettenham, John – Journal of Autism and Developmental Disorders, 2019
To test a central assumption of the increased perceptual capacity account in individuals with Autism Spectrum Disorder (ASD), the effects of perceptual load and target-stimulus degradation on auditory detection sensitivity were contrasted. Fourteen adolescents with ASD and 16 neurotypical controls performed a visual letter search task under three…

Tillmann, Julian; Olguin, Andrea; Tuomainen, Jyrki; Swettenham, John – Journal of Autism and Developmental Disorders, 2015
Recent work on visual selective attention has shown that individuals with Autism Spectrum Disorder (ASD) demonstrate an increased perceptual capacity. The current study examined whether increasing visual perceptual load also has less of an effect on auditory awareness in children with ASD. Participants performed either a high- or low load version…

Remington, Anna; Campbell, Ruth; Swettenham, John – Autism: The International Journal of Research and Practice, 2012
In recent years there has been a growing interest in the role of attention in the processing of social stimuli in individuals with autism spectrum disorders (ASD). Research has demonstrated that, for typical adults, faces have a special status in attention and are processed in an automatic and mandatory fashion even when participants attempt to…

Wellman, Henry M.; Baron-Cohen, Simon; Caswell, Robert; Gomez, Juan Carlos; Swettenham, John; Toye, Eleanor; Lagattuta, Kristin – Autism: The International Journal of Research and Practice, 2002
Two studies with a total of 17 children (ages 5-18) with autism tested a picture-in-the-head strategy for dealing with thoughts and behavior using cartoon thought-bubbles to represent various mental states. The thought-bubble training led to the children passing not only false belief tests but also theory of mind tests. (Contains references.)…
