This study examined, using the Concealed Information paradigm, whether interstimulus intervals (ISI) typically used for electrodermal measurement can be shortened. An ISI ranging from 16 s to 24 s (with a mean of 20 s) was compared with an ISI shortened by 50% using a within-participants design. It was demonstrated that this shortening had no effect on the differential skin conductance responses to the personally significant details and nearly identical detection efficiency was observed under the 2 ISIs. However, overall responses were attenuated with the shorter ISI. The implications of these results for various types of studies, using skin conductance responses, were discussed.
