Abstract: P. G. R. test was given to 42 neurasthenics and 10 normal subjects. The resting curve of the first 15 minutes was recorded; after this period a stimulus for disturbance, and next an alarm of ending experiment were applied in order to study the change scores. It was found that (1) neurasthenics with a state of restlessness, emotionally anxiousness and over-sensitiveness showed greater reactivity than normals; (2) neurasthenics with tiredness showed smaller resting scores and greater responsiveness to stimuli than normal subjects; (3) low correlation was found between the degree of self-sensitiveness and P. G. R.
