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…

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…

There is often a large time gap between caregivers' initial concerns and the diagnosis of autism spectrum disorder. The current study aimed to identify factors associated with missed or delayed autism spectrum disorder diagnoses among children in Colorado. In a surveillance-based sample of 8-year-old children with autism spectrum disorder (N=572),…

Motor challenges are commonly reported in autism spectrum disorder (ASD). Yet, there is substantial heterogeneity in motor ability within ASD, and it is unknown what behavioral characteristics best explain individual differences in motor ability in ASD and related conditions. This observational study examined motor ability as a function of sensory…

White and Remington (2019) found that autistic people may have increased anthropomorphic tendencies to ascribe human-like attributes to non-human agents. However, it was unclear from their study whether this relationship holds after accounting for socio-demographic variables known to be associated with anthropomorphism. The psychometric properties…

Sensory abnormalities in autism has been noted clinically, with pain insensitivity as a specified diagnostic criterion. However, there is limited research using psychophysically robust techniques. Thirteen adults with ASD and 13 matched controls completed an established quantitative sensory testing (QST) battery, supplemented with measures of pain…

Few studies have evaluated the use of assessment to identify the most efficient instructional practices for individuals with autism spectrum disorder. This is problematic as these individuals often have difficulty acquiring skills, and the procedures that may be efficient with one individual may not be for others. The experimenters conducted…

People differ in how strongly they believe that, in general, one gets what (s)he deserves (i.e., individual differences in the "general belief in a just world"). In this study (N = 588; n = 60 with a formal autism diagnosis), whether or not autistic people and those with high autistic traits have a relatively low general belief in a just…

Purpose: This study reports a secondary analysis of the nature of communicative functions and modalities used in initiations and responses of minimally verbal preschoolers with severe autism spectrum disorder (ASD) from a previously published study (Thiemann-Bourque, Feldmiller, Hoffman, & Johner, 2018). This analysis focused on the final…

Introduction: Caregivers of autistic children and caregivers of children with fetal alcohol spectrum disorder (FASD) experience considerable stress. However, what is unique or similar across these groups remains understudied. This study explored how female caregivers of children with FASD who registered to participate in a caregiver focused mental…

The present study examined the relationship between multisensory integration and the temporal binding window (TBW) for multisensory processing in adults with Autism spectrum disorder (ASD). The ASD group was less likely than the typically developing group to perceive an illusory flash induced by multisensory integration during a sound-induced…

Social play and social interactions are essential occupations for children, but can be challenging for children with Autism Spectrum Disorders (ASD). This systematic review investigates cortisol responsivity in children with ASD during naturalistic social play and social interactions. Methodology: Six control and comparison studies of moderate…

Autism Spectrum Disorder (ASD) is generally associated with difficulties in contextual source memory but not single item memory. There are surprising inconsistencies in the literature, however, that the current study seeks to address by examining item and source memory in age and ability matched groups of 22 ASD and 21 comparison adults. Results…

Many individuals with autism spectrum disorder (ASD) have symptoms of sensory hypersensitivity. Several studies have shown high individual variations in temporal processing of tactile stimuli. We hypothesized that these individual differences are linked to differences in hyper-reactivity among individuals with ASD. Participants performed two tasks…

Purpose: Children with autism spectrum disorder (ASD) demonstrate many mechanisms of lexical acquisition that support language in typical development; however, 1 notable exception is the shape bias. The bases of these children's difficulties with the shape bias are not well understood, and the current study explored potential sources of individual…
