Many studies have shown that children with autism spectrum disorder have some understanding of intentions behind others' goal-directed actions on objects. It is not clear whether they understand intentions at a high level of abstraction reliant on the context in which the actions occur. This study tested their understanding of others' prior…

Previous electromyographic studies have reported that individuals with autism spectrum disorders (ASD) exhibited atypical patterns of facial muscle activity in response to facial expression stimuli. However, whether such activity is expressed in visible facial mimicry remains unknown. To investigate this issue, we videotaped facial responses in…

Purpose: The comprehension of tense/aspect morphology by children with autism spectrum disorder (ASD) was assessed via Intermodal Preferential Looking (IPL) to determine whether this population's difficulties with producing these morphemes extended to their comprehension. Method: Four-year-old participants were assessed twice, 4 months apart. They…

Atypical gaze processing has been reported in children with autism spectrum disorders (ASD). Here we explored how infants at risk for ASD respond behaviorally to others' direct gaze. We assessed 10-month-olds with a sibling with ASD (high risk group; n = 61) and a control group (n = 18) during interaction with an adult. Eye-tracking revealed less…

Previous word learning studies suggest that children with autism spectrum disorder may have difficulty understanding pictorial symbols. Here we investigate the ability of children with autism spectrum disorder and language-matched typically developing children to contextualize symbolic information communicated by pictures in a search task that did…

A single-subject, alternating treatment study compared the impact of two types of photograph displays of contrasting contextual complexity. The study examined the impact of high-context and no-context photographs, displayed on an iPad, on the ability of three preschool children with autism spectrum disorder (ASD) to transition to play activities.…

This dissertation describes the development of a state-of-the-art immersive media environment and its potential to motivate high school youth with autism to vocally express themselves. Due to the limited availability of media environments in public education settings, studies on the use of such systems in special education contexts are rare. A…
