Hyperactivity In Boys With Attention-Deficit/Hyperactivity Disorder: A Ubiquitous Core Symptom Or Manifestation Of Working Memor, Jennifer Bolden
Electronic Theses and Dissertations
Hyperactivity is currently considered a core and ubiquitous feature of attention-deficit/hyperactivity disorder (ADHD); however, an alternative model challenges this premise and hypothesizes a functional relationship between working memory (WM) and activity level. The current study investigated whether children s activity level is functionally related to WM demands associated with the domain-general central executive and subsidiary storage/rehearsal components using tasks based on Baddeley s (2007) WM model. Activity level was objectively measured 16 times per second using wrist- and ankle-worn actigraphs while 23 boys between 8 and 12 years of age completed control tasks and visuospatial/phonological WM tasks of increasing memory …
Developmental Trajectory Of Aggressive Behavior In Clinically Referred Boys: A Rasch Analysis, Scott Lafond
Developmental Trajectory Of Aggressive Behavior In Clinically Referred Boys: A Rasch Analysis, Scott Lafond
Electronic Theses and Dissertations
A majority of research investigating aggression and its development in children has relied upon the use of rating scales such as the Child Behavior Checklist (CBCL). These scales are typically developed using a conventional factor analytic approach for the selection and retention of scale items, but may not contain sufficient numbers of items to adequately assess the unidimensional construct or developmental trajectory of aggressive behavior in youths. The present study evaluates specific psychometric properties of CBCL Aggressive and Delinquency Problems clinical syndrome scale items to determine the degree to which they reflect the breadth and established developmental trajectory of aggressive …

Am I Too Fat To Be A Princess? Examining The Effects Of Popular Children's Media On Preschoolers' Body Image, Sharon Hayes
Electronic Theses and Dissertations
The current study investigated the effects of brief exposure to appearance-related media on female preschoolers' body image. Results indicated that exposure did not affect body dissatisfaction or engagement in appearance-related play behaviors. Surprisingly, participants' self-reported frequency of weight concerns decreased at posttest. In contrast to older populations, it is possible that young children may adopt the persona of attractive characters with whom they identify rather than comparing themselves to the characters. This level of identification temporarily may alleviate weight concerns. This is the first empirical study to provide support for previous findings that suggest media exposure does not affect body …
