Problems of Magnitude Measurement with Multiple GSRS

Abstract

In long delay or trace conditioning more than one maximum for the GSR response curve is obtained. CRs expressed as magnitudes of response may employ either stimulus onset points or response onset points as base levels from which to measure changes (GSRs). Data are presented to demonstrate that different magnitude measures (those from CS onset and from CR onset) may yield different sensitivity to independent variation and different values for empirically defined conditioning phenomena. Further data show that responses occurring in close succession during a trial may be interdependent.
