Barrett

Barrett, The Honors College at Arizona State University proudly showcases the work of undergraduate honors students by sharing this collection exclusively with the ASU community.

Barrett accepts high performing, academically engaged undergraduate students and works with them in collaboration with all of the other academic units at Arizona State University. All Barrett students complete a thesis or creative project which is an opportunity to explore an intellectual interest and produce an original piece of scholarly research. The thesis or creative project is supervised and defended in front of a faculty committee. Students are able to engage with professors who are nationally recognized in their fields and committed to working with honors students. Completing a Barrett thesis or creative project is an opportunity for undergraduate honors students to contribute to the ASU academic community in a meaningful way.

A Comparison of Central Executive Function in Children with Typical Development Who Do or Do Not Have ADHD

This study was originally designed to assess the relationship between central executive function and the symptoms of ADHD. To quantify this relationship, the performance of two second graders with typical development (TD) who were also diagnosed with Attention Deficit Hyperactivity Disorder (ADHD) were to be compared to peers with TD but no ADHD. Due to recruitment difficulties, only two participants with ADHD were enrolled. Participants completed four executive function tasks from the Comprehensive Assessment Battery for Children-Working Memory (CABC-WM; Alt, Brinkley, Cabbage, Cowan, Gray, Green, Hogan & Kuo, 2017) including repetition detection auditory and visual and number updating auditory and visual. No concrete results could be made for this study due to only having two participants, however, there are many considerations that can be made due to the completion of this study. The discussion considers how children with ADHD may struggle in school and at home. This study was unable to reach the number of desired participants (5), however, a discussion can be had about the importance of the study and what was learned regarding the research study from this study as well.

Relations Between Central Executive Function and Scores on an ADHD Rating Scale in Second Grade Children

Description

Purpose: Children with attention-deficit/hyperactivity disorder (ADHD) have been found to have central executive deficits in working memory as well as less academic success than children with typical development. The purpose of this study was to determine which components of central executive function were most closely related to parental rating scores of attention.
Method: Two hundred twenty three 2nd graders with typical development, dyslexia, developmental language disorder (DLD), or dyslexia/DLD completed three central executive tasks from the Comprehensive Assessment Battery for Children–Working Memory (Gray, Alt, Hogan, Green, & Cowan, n.d.). Parents of the children completed the ADHD Rating Scale-IV: Home Version for their child. None of the participants had been diagnosed with ADD/ADHD
Results: When diagnostic group performance was compared we found significant differences on each central executive task. When ADHD group performance was compared we found a significant between-group performance only on the n-back visual task with the high-risk group scoring lower than the other two groups. ADHD rating scores predicted a significant amount of variance for each central executive task, but percentages were small (3%-6%).
Discussion: Working memory is known to be related to attention control. Stronger attentional control is associated with a higher working memory performance. Our study showed that children most at risk for ADD/ADHD based on parent ratings scored lowest on the visuospatial task, likely because rehearsal of visuospatial information is not possible so relies more heavily on attention. This study is a step toward considering how attention affects working memory performance so that both can be considered when designing instruction and interventions.
