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

Masters 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. …
