This research investigated the effects of positive and negative air ionization on the early acquisition of a Sidman (1953) avoidance response. The subjects were 20 male albino rats of the Sprague-Dawley strain. They were randomly assigned to ionization conditions and given 4 2-hr. acquisition sessions. The temporal parameters of the task were a response-shock interval of 20 sec. and a shock-shock interval of 5 sec. Shocks were delivered as 1-ma. pulses of 1 sec. duration. The results indicated that at the end of 4 2-hr. sessions the avoidance performance of rats trained in the presence of negative air ions was superior to that of rats trained in the presence of positive air ions.
