The purpose of study was to determine the usefulness of skin resistance and other physiological measures as indicators of a simple cognitive ability such as the immediate recall of digits. Subjects were placed in a sound attenuated chamber and wired for heart rate and skin resistance recordings. The task consisted of the immediate recall of a 10 alternative digit sequence and a two digit alternative sequence. Further experimentation is indicated, in particular, a design in which task difficulty and task duration are systematically varied over several points over a wide range. Author Modified Abstract
