Abstract/Description
Autism is a neurodevelopmental disorder that is characterized by deficits involving social interaction, communication, and perception. Although there is much research that has examined functional neural connectivity in individuals with autism, few have conducted these studies in very young children while awake across EEG power and coherence measures. Anomalies in EEG coherence and power have been associated with deficits in executive function and mental activity. The present study examined...
Show moreAutism is a neurodevelopmental disorder that is characterized by deficits involving social interaction, communication, and perception. Although there is much research that has examined functional neural connectivity in individuals with autism, few have conducted these studies in very young children while awake across EEG power and coherence measures. Anomalies in EEG coherence and power have been associated with deficits in executive function and mental activity. The present study examined neural activation and functional connectivity with an EEG, in children ages 3 -5, during an eyesclosed baseline period. Discrete Fourier Transform was performed on artifact-free segments of EEG data to produce power density values. In addition, coherence measurements were examined to assess functional connectivity in the alpha bandwidth during the baseline recording. Children with autism spectrum disorder (ASD) demonstrated reduced alpha coherence in fronto-temporal regions and between right temporal sites when compared to typically developing (TD) children. In addition, the reduction in coherence was based on ASD severity, such that high-functioning children with ASD showed greater coherence than low-functioning children with ASD. Children with ASD also displayed reduced power in the alpha, beta, and theta frequency bandwidths in frontal, temporal, central, and occipital regions compared to TD children. Interestingly, delta power differentiated children based on developmental status such that high-functioning children with ASD demonstrated the greatest delta power, followed by TD children, and then low-functioning children with ASD. Finally, TD children demonstrated left anterior temporal EEG asymmetry in the alpha bandwidth, whereas children with high-functioning ASD exhibited left posterior temporal EEG asymmetry and right frontal EEG asymmetry. Thus, the results suggest that children with ASD exhibit atypical patterns of brain activity and functional connectivity compared to their typically developing counterparts.

Using WatchMinder to increase the on-task behavior of students with autism spectrum disorder
Title
Using WatchMinder to increase the on-task behavior of students with autism spectrum disorder.
Creator

Abstract/Description
In this study the effectiveness of WatchMinderTM, a vibrating prompt watch, was examined as a component of a self-monitoring intervention package to help students with autism increase on-task behavior during independent seatwork. A multitude of literature since the 1970s has suggested that self-monitoring interventions are integral in increasing task engagement. Tactile prompting devices are a new aspect of self-monitoring interventions, and the limited research has shown that these...
Show moreIn this study the effectiveness of WatchMinderTM, a vibrating prompt watch, was examined as a component of a self-monitoring intervention package to help students with autism increase on-task behavior during independent seatwork. A multitude of literature since the 1970s has suggested that self-monitoring interventions are integral in increasing task engagement. Tactile prompting devices are a new aspect of self-monitoring interventions, and the limited research has shown that these unobtrusive devices are effective for providing feedback to monitor their behavior. Self-graphing is another component of self-monitoring interventions that has received little attention in the literature. However, many studies recognize the importance for individuals to be active participants in their educational programs by analyzing progress and being a part of the decision making process. This study assessed the use of WatchMinder and self-graphing on the on-task behavior of four elementary students with autism in the special education setting.
