Purpose: Categorical perception (CP) manifests in various aspects of human cognition. While there is mounting evidence for CP in facial emotions, CP in vocal emotions remains understudied. The current study attempted to test whether individuals with a tonal language background perceive vocal emotions categorically and to examine how factors such…

This study explored the nature, prevalence, and developmental profiles of sensory processing disorders among children with autism spectrum disorder (ASD). The participants comprised 119 children with ASD and 30 typically developing children and their parents. The Child Sensory Profile-2 was used to assess the children's sensory processing…

Sensory features are common and impairing in autism spectrum disorder (ASD), but there are few observational sensory assessments that are valid across ages. We used the Sensory Processing 3-Dimensional (SP3-D) observed Assessment and parent-reported Inventory to examine sensory responsivity in 41 ASD and 33 typically-developing (TD) youth across…

Multisensory tools are commonly employed within educational settings (e.g. Carter & Stephenson, 2012), and there is a growing body of literature advocating the benefits of presenting children with multisensory information over unisensory cues for learning (Baker & Jordan, 2015; Jordan & Baker, 2011). This is even the case when the…

Self-injurious behavior (SIB) occurs in up to 50% of individuals with autism. As one of the most serious conditions in individuals with developmental disabilities, SIB affects the individual and his or her family in multiple contexts. A systematic analysis of factors most commonly associated with SIB could inform the development of individualized…

Purpose: Differences in communication development impact long-term outcomes of children with autism. Previous research has identified factors associated with communication in children with autism, but much of the variance in communication skill remains unexplained. It has been proposed that early differences in sensory responsiveness (i.e.,…

Adults' judgments of another person's gaze reflect both sensory (e.g., perceptual) and nonsensory (e.g., decisional) processes. We examined how children's performance on a gaze categorization task develops over time by varying uncertainty in the stimulus presented to 6- to 11 year-olds (n = 57). We found that younger children responded…

First-person perspectives of children with autism spectrum disorder are rarely included in research, yet their voices may help more clearly illuminate their needs. This study involved phenomenological interviews with children with autism spectrum disorder (n = 12, ages 4-13) used to gain insights about their sensory experiences. This article…

More than a century ago, Galton and Spearman suggested that there was a functional relationship between sensory discrimination ability and intelligence. Studies have since been able to confirm a close relationship between general discrimination ability (GDA) and IQ. The aim of the present study was to assess whether this strong relationship…

In human adults, visual dominance emerges in several multisensory tasks. In children, auditory dominance has been reported up to 4 years of age. To establish when sensory dominance changes during development, 41 children (6-7, 9-10, and 11-12 years) were tested on the Colavita task (Experiment 1) and 32 children (6-7, 9-10, and 11-12 years) were…

The type, frequency and inter-relationships of emotional and behavioural problems in 863 children with autism spectrum disorder (ASD) were investigated using the population-based Database of children with ASD living in the North East of England (Daslne). A high rate of problems was reported, with 53% of children having 4 or more types of problems…

The aims of this study were to investigate whether individuals with AS have impaired motor abilities and sensorimotor processing and whether these impairments were age-related. Sensorimotor abilities were examined using the Movement Assessment Battery for Children-2, and the Sensory Integration Praxis Test. Fifty boys with AS aged 7-14 years old…

A randomized pretest-posttest control group design was utilized to measure the effects of a platform swing on independent work behaviors of 30 children with Autism Spectrum Disorders (ASD). Participants engaged in two 5-min intervals of independent work. Between the intervals, participants in the treatment group received 5 min of vestibular…

Young children are frequently exposed to sounds such as speech and music in noisy listening conditions, which have the potential to disrupt their learning. Missing input that is masked by louder sounds can, under the right conditions, be "filled in" by the perceptual system using a process known as perceptual restoration. This experiment…

While self-injurious behaviors (SIB) can cause significant morbidity for children with autism spectrum disorders (ASD), little is known about its associated risk factors. We assessed 7 factors that may influence self-injury in a large cohort of children with ASD: (a) atypical sensory processing; (b) impaired cognitive ability; (c) abnormal…
