Eighteen graduate students orally responded to a questionnaire composed of items designed to evoke Parent, Adult, or Child ego states. Measurements of changes in skin temperature, respiration rate, heart rate, and skin conductance associated with shifts in ego states were recorded. Significant changes were reported for six of the twelve comparisons made. Concluded that physiological changes which accompany shifts in ego states provide empirical evidence of the existence of ego states to augment the phenomenologically based observations hitherto utilized.
