Impulsivity And Attention-Deficit/Hyperactivity Disorder (Adhd) Testing Competing Predictions From The Working Memory And Behavioral Inhibition Models Of Adhd, Joseph S. Raiker
Impulsivity And Attention-Deficit/Hyperactivity Disorder (Adhd) Testing Competing Predictions From The Working Memory And Behavioral Inhibition Models Of Adhd, Joseph S. Raiker
Electronic Theses and Dissertations
Impulsivity is a hallmark of two of the three DSM-IV ADHD subtypes and is associated with myriad adverse outcomes. Limited research, however, is available concerning the mechanisms and processes that contribute to impulsive responding by children with ADHD. The current study tested predictions from two competing models of ADHD – working memory (WM) and behavioral inhibition (BI) – to examine the extent to which ADHD-related impulsive responding was attributable to model-specific mechanisms and processes. Children with ADHD (n = 21) and typically developing children (n = 20) completed laboratory tasks that provided WM (domaingeneral central executive [CE], phonological/visuospatial storage/rehearsal) and …
Effects Of 3d Stereoscopy, Visuo-Spatial Working Memory, And Perceptions Of Simulation Experience On The Memorization Of Confusable Objects, Joseph R. Keebler
Effects Of 3d Stereoscopy, Visuo-Spatial Working Memory, And Perceptions Of Simulation Experience On The Memorization Of Confusable Objects, Joseph R. Keebler
Electronic Theses and Dissertations
This dissertation investigated the impact of active stereoscopic 3-dimensional (3D) imagery equipment and individual differences in visuo-spatial working memory (VSWM) capacity on retention of a set of similar, novel objects (i.e., armored military vehicles). Seventy-one participants were assessed on their visuo-spatial working memory using the Visual Patterns Test (Della Sala, Gray, Baddeley, & Wilson, 1997). They were then assigned to one of four different conditions (3D high VSWM, 3D low VSWM, 2D high VSWM, 2D low VSWM) based upon their visuo-spatial working memory. Participants were then trained to identify military vehicles using a simulation that presented the training stimuli in …
