Graduate Theses, Dissertations, and Problem Reports
Reducing cardiovascular responses to stressors may help to reduce one's risk of developing cardiovascular disease. The present study examined the underlying hemodynamic changes that accompany heart rate (HR) response reduction to a stressor following HR feedback training. Twenty-five healthy college males were assigned to either a HR feedback training group (FB+) or a control group (FB--) and were presented with a videogame and mental arithmetic challenge, as HR, blood pressure, and impedance cardiography-derived measures were recorded. During the training sessions, the FB+ group received HR feedback and the FB-- group was not provided with HR feedback while playing the videogame. …

Identification Of Math Anxiety Subtypes, Aline Elizabeth Rabalais
Graduate Theses, Dissertations, and Problem Reports
Conceptualizations of mathematics anxiety, as well as factors that are empirically related to it, were identified from the existing literature. These factors are test, evaluation, trait, and state anxiety, as well as gender and level of math ability. Differences in these factors were hypothesized to distinguish subtypes of highly math anxious individuals from one another. In order to determine whether subtypes exist, cluster analyses were performed on a sample of 96 highly math anxious college students. The results revealed three clusters distinguished by completion time on two versions of a math test and age. Furthermore, participants' responses on a variety …
