Error Processing And Naturalistic Actions Following Moderate-To-Severe Traumatic Brain Injury, Daniel A. Good
Error Processing And Naturalistic Actions Following Moderate-To-Severe Traumatic Brain Injury, Daniel A. Good
Theses and Dissertations
Moderate-to-severe traumatic brain injury (M/S TBI) can affect an individual's ability to perform daily tasks. For example, individuals with M/S TBI are more likely to commit errors on tasks such as making a meal or wrapping a present. The neural processes involved in such errors are poorly understood. Studies suggest that neurophysiologic markers of cognitive control and error processing may be helpful in gaining additional insight into errors on naturalistic action tasks. Unfortunately, previous experimental methods left a methodological gap which limited the use of neurophysiological markers in the study of naturalistic action. Several recent studies in healthy adults have …
The Psychophysiology Of Novelty Processing: Do Brain Responses To Deviance Predict Recall, Recognition And Response Time?, Siri-Maria Kamp
The Psychophysiology Of Novelty Processing: Do Brain Responses To Deviance Predict Recall, Recognition And Response Time?, Siri-Maria Kamp
USF Tampa Graduate Theses and Dissertations
Events that violate expectations are biologically significant and accordingly elicit various physiological responses. We investigated the functional relationship between three of these responses: the P300, the Novelty P3 and the pupil dilation response (PDR), with a particular focus on their co-variance with reaction time and measures of subsequent memory. In a modified Novelty P3 oddball paradigm, participants semantically categorized a sequence of stimuli including (1) words of a frequent category, (2) words of an infrequent category (14% of the trials) and (3) pictures of the frequent category (14% of the trials). The Novelty P3 oddball task was followed by a …
Defining Semantic Space And Degree Of Association Using Brainwaves: An Erp Investigation Of Alcohol Expectancies, Ty Brumback
Defining Semantic Space And Degree Of Association Using Brainwaves: An Erp Investigation Of Alcohol Expectancies, Ty Brumback
USF Tampa Graduate Theses and Dissertations
The current study investigated the cognitive organization of alcohol expectancies using event-related potentials (ERPs). Building on previous behavioral and ERP paradigms, the goal of the current study was to quantify the relationship among alcohol expectancies using ERP indices of salience, congruence, and cognitive distance. The ERP components being evaluated fit perfectly into the alcohol expectancy theory and research; however, implementing specific paradigms to reliably measure individual differences in alcohol expectancies using ERPs has proven to be more elusive than originally thought. This study utilized established cognitive modeling techniques coupled with ERP responses to linguistic stimuli. In essence, this study provides …
