The Relationship Between Adverse Childhood Experiences, Acute Stress, And Working Memory, Marissa R. Jones
The Relationship Between Adverse Childhood Experiences, Acute Stress, And Working Memory, Marissa R. Jones
Electronic Theses and Dissertations
Working memory (WM) is a crucial component of cognitive function that affects learning, reasoning, and problem solving, all of which are important for daily functioning. Therefore, addressing factors that can impact working memory, such as stress, are incredibly relevant to understanding WM efficiency. WM is an important component of higher order cognitive function and high WM capacity has been shown to be important for academic and occupational performance. Thus, understanding the relationship between stress-related factors and WM could aid in identifying strategies to mitigate the deleterious effects of stress on working memory. Although some previous research has indicated a negative …
Error-Related Negativity And Feedback-Related Negativity On A Reinforcement Learning Task, Elizabeth Ridley
Error-Related Negativity And Feedback-Related Negativity On A Reinforcement Learning Task, Elizabeth Ridley
Electronic Theses and Dissertations
Event-related potentials play a significant role in error processing and attentional processes. Specifically, event-related negativity (ERN), feedback-related negativity (FRN), and the P300 are related to performance monitoring. The current study examined these components in relation to subjective probability, or confidence, regarding response accuracy on a complicated learning task. Results indicated that confidence ratings were not associated with any changes in ERN, FRN, or P300 amplitude. P300 amplitude did not vary according to participants’ subjective probabilities. ERN amplitude and FRN amplitude did not change throughout the task as participants learned. Future studies should consider the relationship between ERN and FRN using …
