The Effect That Testing Has On Nondeclarative Memory, David Smith Dec 2020

The Effect That Testing Has On Nondeclarative Memory, David Smith

Electronic Theses and Dissertations

Testing has been shown to improve long-term memory retention by decreasing the amount of material forgotten, a phenomenon known as the testing effect. This positive impact of testing has been shown using direct tests of memory that require declarative memory, things like memorizing word-pairs and single-word lists. This dissertation is the first research to investigate how testing impacts nondeclarative memory using three experiments. The first and second experiment utilize the word fragment completion task to measure the effect that testing has on words learned via methodology thought to recruit either declarative or nondeclarative memory. The third experiment utilizes a probabilistic …


The Relationship Between Adverse Childhood Experiences, Acute Stress, And Working Memory, Marissa R. Jones May 2020

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 May 2020

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 …


Smartphones, Stress, And The Reduction Of Cognitive Resources, Jenay R. Stone Jan 2020

Smartphones, Stress, And The Reduction Of Cognitive Resources, Jenay R. Stone

Electronic Theses and Dissertations

Smartphones are a ubiquitous part of daily life for most Americans. They offer an abundance of information, connectivity, and entertainment. Previous research suggests that smartphones are also responsible for cognitive costs in educational, public, private and professional settings when in use or audibly creating stimuli in the environment. Smartphones are also linked to an automatic attenuation of cognitive resources even when not in use and merely salient (Ward, Duke, Gneezy and Bos; Journal of the Association for Consumer Research; 2, 141, 154, 2017). The purpose of the present study was to experimentally test the effect of cell phone salience …
