The Electrophysiological And Neuropsychological Organization Of Long Term Memory, Richard J. Addante
The Electrophysiological And Neuropsychological Organization Of Long Term Memory, Richard J. Addante
Psychology Faculty Publications
The electrophysiological correlates of recognition memory retrieval were examined in order to identify the neural conditions that precede accurate memory retrieval, characterize the processes that contribute to high and low confidence memory responses, and determine which memory processes are impaired after brain injury. Human electroencephalogram (EEG) was recorded during recognition confidence and source memory judgments in three experiments. In Experiment 1, mid-frontal pre-stimulus theta oscillations were found to precede the stimulus presentation of items that were successfully recollected, but they were not found to be predictive of item familiarity. Moreover, during stimulus presentation, recollection was associated with an increase in …

The Impact Of Category Separation On Unsupervised Categorization, Shawn W. Ell, Gregoryh F. Ashby
Psychology Faculty Scholarship
Most previous research on unsupervised categorization has used unconstrained tasks in which no instructions are provided about the underlying category structure or the stimuli are not clustered into categories. Few studies have investigated constrained tasks in which the goal is to learn pre-defined stimulus clusters in the absence of feedback. These studies have generally reported good performance when the stimulus clusters could be separated by a one-dimensional rule. The present study investigated the limits of this ability. Results suggest that even when two stimulus clusters are as widely separated as in previous studies, performance is poor if within-category variance on …
Dissociable And Dynamic Components Of Cognitive Control: A Developmental Electrophysiological Investigation, Matthew Waxer
Dissociable And Dynamic Components Of Cognitive Control: A Developmental Electrophysiological Investigation, Matthew Waxer
Electronic Thesis and Dissertation Repository
One standard task used to investigate the development of cognitive control is the Dimensional Change Card Sort (DCCS). Performance and patterns of brain activity associated with the DCCS show continued age-related advances into early adolescence. According to many theoretical accounts, the DCCS places demands on a single underlying executive control process. Three experiments examined the possibility that the DCCS places demands on multiple control processes that follow distinct developmental trajectories. In Experiment 1, rule switching and conflict processing made orthogonal contributions to DCCS performance. Rule switching was associated with a cue-locked late frontal negativity (LFN) event-related potential (ERP) and conflict …
Reflexivity In Financial Markets: A Neuroeconomic Examination Of Uncertainty And Cognition In Financial Markets, Steven Pikelny
Reflexivity In Financial Markets: A Neuroeconomic Examination Of Uncertainty And Cognition In Financial Markets, Steven Pikelny
Senior Projects Spring 2011
Financial markets exist to disperse the risks of an unknown future in an economy. But for this process to work in an optimal fashion, investors – and subsequently markets – must have a way to interpret uncertainty. The investor rationality and market efficiency literature utilizes a methodology inadequate to address this fact, so I supplement it with the perspectives of epistemology, economic sociology, neuroscience, cognitive science, and philosophy of mind. This approach suggests that what is commonly viewed as market “inefficiency” is not necessarily caused by investor irrationality, but rather by the inherent nature of the epistemological problem faced by …
