The application of anticipatory avoidance learning to the treatment of homosexuality—II: Avoidance response latencies and pulse rate changes

Abstract

As part of a research programme on the application of anticipatory avoidance learning to the treatment of homosexuality, recordings of avoidance response latencies and pulse rate changes to the male photographs, used as conditional stimuli, were made. Detailed data on response latencies for four of our patients, and on pulse rate changes for two of these four are presented. Response latencies display a regular learning curve in patients who improve with treatment, but do not do so in those who relapse or fail to improve. Pulse rate changes to the CS were conditioned in one patient who improved with treatment, but not in another who did not. Our results suggest an association between pronounced pulse rate changes and suceessful avoidance learning, and conversely between an absence of pulse rate changes and poor avoidance learning. This finding parallels results obtained in animal studies, and appears to have a predictive value for behaviour during follow-up. More comprehensive studies in these areas are planned.
