We integrated data from a newborn hearing screening database and a preschool disability database to examine the relationship between newborn click evoked auditory brainstem responses (ABRs) and developmental disabilities. This sample included children with developmental delay (n = 2992), speech impairment (SI, n = 905), language impairment (n =…

Tactile defensiveness, characterized by behavioral hyperresponsiveness and negative emotional responses to touch, is a common manifestation of aberrant sensory processing in autism spectrum disorders (ASD) and other developmental disabilities (DD). Variations in tactile defensiveness with the properties of the stimulus and the bodily site of…

To evaluate evidence for motor impairment specificity in autism spectrum disorder (ASD) and attention deficit/hyperactivity disorder (ADHD). Children completed performance-based assessment of motor functioning (Movement Assessment Battery for Children: MABC-2). Logistic regression models were used to predict group membership. In the models…

Gaze avoidance is a hallmark behavioral feature of fragile X syndrome (FXS), but little is known about whether abnormalities in the visual processing of faces, including disrupted autonomic reactivity, may underlie this behavior. Eye tracking was used to record fixations and pupil diameter while adolescents and young adults with FXS and sex- and…

The purpose of this study was to investigate the impact of visual strategies with preschool children with autism spectrum disorders (ASD) and their peers during play group sessions. A changing-criterion design was implemented with three preschool-aged children with ASD while they participated in play groups with four typically-developing peers.…

This study examined Theory of Mind in Williams syndrome (WS) and in normal chronological age-matched and mental age-matched control groups, using a picture sequencing task. This task assesses understanding of pretence, intention and false belief, while controlling for social-script knowledge and physical cause-and-effect reasoning. The task was…

Thirty-four school-aged children with developmental disabilities were assessed for level of tactile defensiveness (TD) and then presented with a repeated tactile stimulus while engaged in computer games. Evidence was found for a differential sensitivity in TD but not an inhibition deficit. Another finding included a negative correlation between TD…

This study compared 20 children (ages 8-14) with either autism or receptive developmental language disorder (RDLD) to 10 controls in their ability to detect frequent and infrequent randomly presented auditory stimuli. Only the children with autism demonstrated an abnormally small amplitude of the P3b, a component of the event-related brain…

Nineteen adults with developmental disabilities, judged competent in facilitated communication, participated in a validation study using an information passing design requiring short-term recall of stimulus cards with shapes, colors, and numbers. Results failed to validate facilitated communication for the group as a whole, any individual…
