Reinforcement Learning In Individuals At Risk For Alzheimer's Disease, Christina Marie Figueroa
Master's Theses (2009 -)
Explicit memory is the hallmark of impairment in Alzheimer’s disease (AD) while implicit memory has mixed task-dependent results. Models of memory processes have posited that hippocampal function is sensitive to reinforcement learning (RL), which involves both explicit and implicit memory. The hippocampus is also vital for the transfer of learned associations to novel situations. Nevertheless, RL paradigms have been underutilized in assessing memory processes in individuals at risk for AD, which may aid in early identification of cognitive decline. Thirty-six apolipoprotein-E (APOE) genotyped older adults (Male n=8; Mage=80; Meducation=15 years) performed word stem completion, word recognition, and RL tasks. The …

The Influence Of Anger On Implicit Biases, Katherine Reiter
Master's Theses (2009 -)
Interpretation of ambiguous information is influenced by anxious (Richards, Reynolds, & French, 1992) and depressive (Wisco, & Nolen-Hoeksema, 2010) symptoms. Emotion regulation strategies, and in particular, cognitive reappraisal has shown to be effective at reducing feelings of distress (Denson, Grisham, & Moulds, 2011). The current study seeks to understand the extent that emotion regulation can influence interpretation bias, thoughts and behaviors. In the current study, participants underwent both Angry and Neutral mood inductions. For each mood condition, participants were instructed to cognitively reappraise and attend to their emotions. Participants rated the degree of negative affect they experienced, and completed 6 …
