Abstract

The effects of exposure to various climatic conditions were analyzed to determine whether these conditions could produce aggression or facilitate shock-elicited aggression. Paired rats and single monkeys were used as subjects. The effects of independent and simultaneous changes in temperature and relative humidity were investigated in an attempt to produce aggression. Temperature, relative humidity, and length of exposure to climatic conditions were varied to determine if these conditions would facilitate shock-elicited aggression. The climatic conditions investigated were ineffective in reliably producing aggression between rats and also in facilitating shock-elicited aggression with rats and monkey subjects. Exposure to temperatures above 24.4°C produced a temporary decrease in shock-elicited fighting between rats and a temporary increase in shock-elicited hosebiting with monkeys. Data between sessions, experimental phases and subjects were variable.
