Measures of long‐range stability of spontaneous GSRs (Galvanic Skin Response) were obtained from 23 male university students. Records were taken throughout a weekly recording period and compared with measures obtained under identical conditions 30 days later. In addition to the investigation of long‐term spontaneous GSR stability, this design permitted analysis of the 24‐hr stability of measured responses within each of the recording periods. Results yielded significant correlations between measures obtained 24 hr apart, as well as a significant correlation between the median weekly rates of spontaneous GSR emission taken 30 days apart. Comparison of emission rates on comparable recording days 30 days apart failed to manifest a significant relationship. Present data support earlier studies of 24‐hr spontaneous GSR stability. In spite of the failure to find significant relationships between emission rates on comparable days of the two recording periods, the authors conclude that the significant relationship between median weekly rates of emission, taken 30 days apart, indicates that spontaneous GSR is an intra‐individual characteristic which remains relatively stable, even over extended periods of time.
