A psychophysiological assessment battery.

This research project was the first step in the development of a psychophysiological assessment battery. The battery consisted of eight tasks that have a history of use within the field of psychophysiology. These tasks were examined on a nonpathological, physically healthy sample. This sample was administered the assessment battery three times over the course of 16 weeks. The response systems of HR, SC, RR, TPA, and FPA were examined. Two major research questions were then examined. The first question was whether a subject would display a stable physiological profile on the assessment battery across the three administrations. The second question was whether there would be individual differences in physiological profiles on the assessment battery. These differences were examined in terms of individual response stereotypy (IRS) and stimulus response specificity (SRS). Depending on the task, from 30 to 100% of the subjects displayed stable physiological profiles across administrations. Twenty-five subjects displayed a high degree of SRS. Five subjects displayed a high degree of IRS.
