ABSTRACT
PSYCHOPHYSICAL INVESTIGATIONS WITH THE
GALVANOMETER AND PNEUMOGRAPH IN
by Frederick Peterson and C. G. Jung 1036 These investigations were carried out in the laboratory of
the Clinic for Psychiatry at Zurich, to the director of which, Professor E. Bleuler, we are under obligation for the use of apparatus and material for study. The purposes of our research were to ascertain the value of the so-called "psycho-physical galvanic reflex'' as a recorder of psychical changes in connection with sensory and psychical stimuli; to determine its normal and pathological variations; to study the respiratory innervation curve in the same relations; and finally to compare the galvanometric and pneumographs curves taken simultaneously upon the kymograph, under the influence of various stimuli. In word-associations the reaction-time was also registered for further comparison.
