Thus far there have been only a few studies of the psychogalvanic response as re lated to mental work. All of these have been carried out with a very small number of subjects. Widely varying types of material have been used. Changes in the difficulty, complexity, or Speed of performance of the mental work have not been objectively measured, and have been quantitatively varied only in a very indefinite fashion. The writer has endeavored in the present experiment to meet as far as possible these hitherto unfulfilled conditions.
