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…

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…

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…

Mazzoni, Noemi; Ricciardelli, Paola; Actis-Grosso, Rossana; Venuti, Paola – Journal of Autism and Developmental Disorders, 2022
In this study, we investigated whether the difficulties in body motion (BM) perception may led to deficit in emotion recognition in Autism spectrum disorder (ASD). To this aim, individuals with high-functioning ASD were asked to recognise fearful, happy, and neutral BM depicted as static images or dynamic point-light and full-light displays.…

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…

Mastergeorge, Ann M.; Kahathuduwa, Chanaka; Blume, Jessica – Journal of Autism and Developmental Disorders, 2021
Eye-tracking represents a sensitive, direct measure of gaze allocation and goal-directed looking behaviors that correspond to visual information processing. Clear definitions and standardization of research protocols to document the utility and feasibility of these methods are warranted. This systematic review provides an account of stimuli…

Poole, Daniel; Gowen, Emma; Warren, Paul A.; Poliakoff, Ellen – Journal of Autism and Developmental Disorders, 2017
Previous studies have indicated that visual-auditory temporal acuity is reduced in children with autism spectrum conditions (ASC) in comparison to neurotypicals. In the present study we investigated temporal acuity for all possible bimodal pairings of visual, tactile and auditory information in adults with ASC (n = 18) and a matched control group…

Maule, John; Stanworth, Kirstie; Pellicano, Elizabeth; Franklin, Anna – Journal of Autism and Developmental Disorders, 2018
It has been suggested that attenuated adaptation to visual stimuli in autism is the result of atypical perceptual priors (e.g., Pellicano and Burr in "Trends Cogn Sci" 16(10):504-510, 2012. doi:10.1016/j.tics.2012.08.009). This study investigated adaptation to color in autistic adults, measuring both strength of afterimage and the…

Irwin, Julia; Avery, Trey; Kleinman, Daniel; Landi, Nicole – Journal of Autism and Developmental Disorders, 2022
Children with autism spectrum disorders have been reported to be less influenced by a speaker's face during speech perception than those with typically development. To more closely examine these reported differences, a novel visual phonemic restoration paradigm was used to assess neural signatures (event-related potentials [ERPs]) of audiovisual…

English, Michael C.; Maybery, Murray T.; Visser, Troy A. – Journal of Autism and Developmental Disorders, 2017
Neurotypical individuals display a leftward attentional bias, called pseudoneglect, for physical space (e.g. landmark task) and mental representations of space (e.g. mental number line bisection). However, leftward bias is reduced in autistic individuals viewing faces, and neurotypical individuals with autistic traits viewing "greyscale"…

Brodeur, Darlene A.; Stewart, Jillian; Dawkins, Tamara; Burack, Jacob A. – Journal of Autism and Developmental Disorders, 2018
The findings are evidence that persons with ASD benefit more than typically developing (TD) persons from spatial framing cues in focusing their attention on a visual target. Participants were administered a forced-choice task to assess visual filtering. A target stimulus was presented on a screen and flanker stimuli were presented simultaneously…

Kumazaki, Hirokazu; Kikuchi, Mitsuru; Yoshimura, Yuko; Miyao, Masutomo; Okada, Ken-ichi; Mimura, Masaru; Minabe, Yoshio – Journal of Autism and Developmental Disorders, 2018
Understanding the nature of olfactory abnormalities is crucial for optimal interventions in children with autism spectrum disorders (ASD). However, previous studies that have investigated odor identification in children with ASD have produced inconsistent results. The ability to correctly identify an odor relies heavily on visual inputs in the…

Hochhauser, Michal; Aran, Adi; Grynszpan, Ouriel – Journal of Autism and Developmental Disorders, 2018
Visual attention of adolescents with autism spectrum disorder (ASD) was assessed using a change blindness paradigm. Twenty-five adolescents with ASD aged 12-18 years and 25 matched typically developing (TD) adolescents viewed 36 pairs of digitized real-world images. Each pair of images was displayed in a "flicker paradigm" whereby a…

Poole, Daniel; Gowen, Emma; Warren, Paul A.; Poliakoff, Ellen – Journal of Autism and Developmental Disorders, 2015
It has been suggested that the sensory symptoms which affect many people with autism spectrum conditions (ASC) may be related to alterations in multisensory processing. Typically, the likelihood of interactions between the senses increases when information is temporally and spatially coincident. We explored visual-tactile interactions in adults…

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…
