Abstract
Following an incidental finding that psychogalvanometer response measures were related to temperature and humidity readings taken at the same time, the nature of the relationship was examined in greater detail. A sizeable relationship between temperature and conductance response measures is found only in a neurotic group and only above an effective temperature of 66° F. This relationship appears to be a function of the position of the response within the total experimental session, and may be dependent upon the relative excitation, or recovery from excitation, of the subject. Humidity in general, affects only the basal conductance level and, does so in both normal and neurotic groups. The relationship between temperature and humidity is probably a complicated one and cannot be corrected for by simple regression except if the majority of scores be within a particular range of humidity readings.
