Cardiovascular Responses To The Combination Of Caffeine And The Repeated Acquisition And Performance Procedure, Cristin L. Sullivan Dec 1995

Cardiovascular Responses To The Combination Of Caffeine And The Repeated Acquisition And Performance Procedure, Cristin L. Sullivan

Master's Theses

The present study examined cardiovascular responses to the combination of caffeine (250 mg) and the repeated acquisition and performance procedure (RAPP) in humans. Six male subjects were tested in a within-subject, double-blind design. Repeated measurements of frontalis electromyogram (EMO), hand-skin temperature, heart rate, respiration, systolic blood pressure, and diastolic blood pressure were obtained during pre-drug, post-drug, acquisition, performance, and recovery periods. Measures of rate, percent error, and true error were obtained during the acquisition and performance components of the RAPP. Drug conditions (caffeine and placebo) and test orders (acquisition before performance and performance before acquisition) were pseudo- random across subjects ...


The Hormones Of Pregnancy Alter Somal Size In The Medial Preoptic Area Of The Rat Brain, Lori A. Keyser May 1995

The Hormones Of Pregnancy Alter Somal Size In The Medial Preoptic Area Of The Rat Brain, Lori A. Keyser

Master's Theses

Formerly non-responsive females will display maternal behavior (MB) following pregnancy and parturition. The behavioral alterations are believed to occur in response to hormonal changes that accompany pregnancy. The medical pre optic area (MPOA) regulates hormone-induced MB. The current study examined neuronal changes which might account for the modified behavior. Twenty adult female Sprague-Dawley rats were assigned a hormone condition: ovariectomized (OVX), ovariectomized/hormone-treated (P+E2), intact diestrus (DI), or pregnant (PREG). Animals were killed, and their brains fixed in Golgi-Cox solution. Somata of the MPOA and related cortex were measured in each group using a Bioquant imaging system. Pregnant ...


The "Unstinted Effort" Of Social Comparison : Biases In The Retrieval Of Behavior Among Depressives And Nondepressives, Michele Christine Fejfar May 1995

The "Unstinted Effort" Of Social Comparison : Biases In The Retrieval Of Behavior Among Depressives And Nondepressives, Michele Christine Fejfar

Master's Theses

The egocentric bias, peoples' tendency to view themselves as better than others, has been found to exist in many different domains (Messick, Bloom, Boldizar, & Samuelson, 1985). Fejfar, Proudfoot, Allison, and Beggan (1994) uncovered evidence supporting two components to the bias: the motivation to be egocentric and the construction of strategies to fulfill this motivation. In the present research, this model was used to determine the biases inherent in depressive (as opposed to nondepressive) cognitions by having subjects list good and bad behaviors performed by themselves and others. Subjects directly or indirectly compared themselves to others (to test the motivation component ...


Television And Its Relationship To A Person's Character, Keri Phillips Jan 1995

Television And Its Relationship To A Person's Character, Keri Phillips

Master's Theses

The following study looked at the relationship between the types of television shows a person watches, either violent, neutral, or nonviolent, and his/her score on the Character Counts Questionnaire (CCQ), which measures a person's character and ethical values. Subjects were asked to complete the CCQ and rate on a five point bipolar scale, whether they enjoyed or did not enjoy watching the selected television shows. While using the CCQ, several problems were found and changes were made to overcome them. The most prevalent problem was that the original scoring method was so rigid it did not give a ...


The Influence Of Emotion On Temporal Perspectives, Skye Mims Ochsner Jan 1995

The Influence Of Emotion On Temporal Perspectives, Skye Mims Ochsner

Master's Theses

Recent research suggests that our understanding of the abstract domain of time is dependent on the more concrete domain of space. At once time is measurable and abstract, thus we often think of it both temporally as well as spatially. Boroditsky and Ramscar (2002) find that the spatial domain influences whether people see themselves as moving through time (ego-moving perspective) or as time moving towards them (timemoving perspective). Might there be other factors at work influencing these perspectives other than just representations of spatial experience? The current studies investigate the role that emotion plays in construal of time. Specifically, do ...
