Phonological Working Memory Deficits In Adhd Revisited: The Role Of Lower-Level Information Processing Deficits In Impaired Working Memory Performance, Joseph Raiker
Electronic Theses and Dissertations
Working memory deficits in children with ADHD are well established; however, insufficient evidence exists concerning the degree to which lower-level cognitive processes contribute to these deficits. The current study dissociates lower level information processing abilities (i.e., visual registration, orthographic conversion, and response output) in children with ADHD and typically developing children and examines the unique contribution of these processes to their phonological working memory performance. Thirty-four boys between 8 and 12 years of age (20 ADHD, 14 typically developing) were administered novel information processing and phonological working memory tasks. Between-group differences were examined and bootstrap mediation analysis was used to …
Impacts Of Complexity And Timing Of Communication Interruptions On Visual Detection Tasks, Sally Stader
Impacts Of Complexity And Timing Of Communication Interruptions On Visual Detection Tasks, Sally Stader
Electronic Theses and Dissertations
Auditory preemption theory suggests two competing assumptions for the attention-capturing and performance-altering properties of auditory tasks. In onset preemption, attention is immediately diverted to the auditory channel. Strategic preemption involves a decision process in which the operator maintains focus on more complex auditory messages. The limitation in this process is that the human auditory, or echoic, memory store has a limit of 2 to 5 seconds, after which the message must be processed or it decays. In contrast, multiple resource theory suggests that visual and auditory tasks may be efficiently time-shared because two different pools of cognitive resources are used. …
