Physiological Indices of a Simple Cognitive Task.
A study attempted to determine the usefulness of skin resistance and other physiological measures as indicators of a simple cognitive skill 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 involved immediate recall of a 10 alternative digit sequence and a two digit alternative sequence. Results indicated no statistically significant relationship between physiological measures of alertness (skin conductance and heart rate) and a simple cognitive task (digit recall). Further experimentation is required to resolve ambiguity of results; in particular, a design is needed in which task difficulty and task duration are systematically varied over several points over a wide range.
