When Bad Stress Goes Good: Increased Threat Reactivity Predicts Improved Category Learning Performance, Shawn W. Ell, Brandon Cosley, Shannon L. Mccoy
When Bad Stress Goes Good: Increased Threat Reactivity Predicts Improved Category Learning Performance, Shawn W. Ell, Brandon Cosley, Shannon L. Mccoy

The way in which we respond to everyday stressors can have a profound impact on cognitive functioning. Maladaptive stress responses in particular are generally associated with impaired cognitive performance. We argue, however, that the cognitive system mediating task performance is also a critical determinant of the stress-cognition relationship. Consistent with this prediction, we observed that stress reactivity consistent with a maladaptive, threat response differentially predicted performance on two categorization tasks. Increased threat reactivity predicted enhanced performance on an information-integration task (i.e., learning is thought to depend upon a procedural-based memory system), and a (nonsignificant) trend for impaired performance on a …
Rule-Based Categorization Deficits In Focal Basal Ganglia Lesion And Parkinson’S Disease Patients, Shawn W. Ell, Andrea Weinstein, Richard Ivry
Rule-Based Categorization Deficits In Focal Basal Ganglia Lesion And Parkinson’S Disease Patients, Shawn W. Ell, Andrea Weinstein, Richard Ivry
Psychology Faculty Scholarship
Patients with basal ganglia (BG) pathology are consistently found to be impaired on rule-based category learning tasks in which learning is thought to depend upon the use of an explicit, hypothesis-guided strategy. The factors that influence this impairment remain unclear. Moreover, it remains unknown if the impairments observed in patients with degenerative disorders such as Parkinson’s disease (PD) are also observed in those with focal BG lesions. In the present study, we tested patients with either focal BG lesions or PD on two categorization tasks that varied in terms of their demands on selective attention and working memory. Individuals with …
The Effects Of Handedness And Bilateral Saccadic Eye Movements On False Alarms In Recognition Memory, Lisa Weinberg
The Effects Of Handedness And Bilateral Saccadic Eye Movements On False Alarms In Recognition Memory, Lisa Weinberg
Psychology Honors Projects
Handedness can be used as a marker for interhemispheric interaction, which can produce memory benefits. Bilateral saccadic eye movements can be used to manipulate levels of interhemispheric interaction. This study measured the effects of handedness and bilateral saccadic eye movement on memory using the Deese-Roediger-McDermott paradigm. This study predicted a memory advantage for left-handers and mixed-handers without eye movements and an advantage for right-handers with the eye movements. The results do not support these predictions but do suggest that handedness is a factor in episodic memory performance. The analyses for this study were run using A’ to compare false alarm …
Locus Of Control And The Age Difference In Free Recall From Episodic Memory, Paul Amrhein, Judith K. Bond, Derek Hamilton
Locus Of Control And The Age Difference In Free Recall From Episodic Memory, Paul Amrhein, Judith K. Bond, Derek Hamilton
Department of Psychology Faculty Scholarship and Creative Works
The authors investigated the relation of locus of control (LOC) to age differences in free-recall memory performance. Older and younger participants completed P. C. Duttweiler's (1984) Internal Control Index (ICI) and subsequently performed free-recall memory tasks. Compared with the younger participants, the older participants exhibited poorer recall with more intrusions and uncorrected repetition errors as well as reduced categorical clustering. For the older participants with less internal LOC, recall proportion and item-pair associative recall clustering were lower than for the older participants with more internal LOC. By contrast, the younger participants did not exhibit any LOC effects in their recall …
