Preschool Executive Function Predicts Childhood Resting State Functional Connectivity And Adhd And Depression, Elizabeth Hawkey
Preschool Executive Function Predicts Childhood Resting State Functional Connectivity And Adhd And Depression, Elizabeth Hawkey
Arts & Sciences Electronic Theses and Dissertations
Background: Measures of executive function (EF), such as the Behavior Rating Inventory of Executive Function, distinguish children with Attention-Deficit/Hyperactivity Disorder (ADHD) from control children, but less work has examined relationships to depression or brain network organization. This study examined whether early childhood EF predicted a new onset or worsening of ADHD and/or depression, and examined how early childhood EF related to functional connectivity of brain networks at school age. Methods: Participants were 247 children, enrolled at ages 3-6, from a prospective study of emotion development. The BRIEF Global Executive Composite (BRIEF-GEC) was used as the measure of EF in early …
The Impact Of Delay On Retrieval Success In The Parietal Memory Network, Nathan Anderson
The Impact Of Delay On Retrieval Success In The Parietal Memory Network, Nathan Anderson
Arts & Sciences Electronic Theses and Dissertations
Recent work has identified a Parietal Memory Network (PMN), which exhibits regular patterns of activation during memory encoding and retrieval. Among these characteristic patterns, this network displays a strong “retrieval success” effect, showing greater activation for correctlyremembered studied items (hits) compared to correctly-rejected novel items (CRs). To date, most relevant studies have used short retention intervals. Here, we ask if the retrieval success effect seen in the PMN would remain consistent over a delay. Twenty participants underwent fMRI while encoding and recognizing scenes. Greater activity for hits than for correctly-rejected lures within PMN regions was observed after a short delay …
