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.

In order to compare the effects of 2 methods of extra-schedule shock delivery on avoidance behavior, 4 Sprague-Dawley rats were trained to stable performance on a Sidman avoidance schedule (RS = 15, Ss = 5). When avoidance behavior was punished on a fixed ratio schedule, response rates decreased and all animals avoided fewer shocks. After re-establishing the avoidance baselines, the mean number of previously obtained punishment shocks were presented in a non-contingent manner. Under this condition, avoidance response rates were uniformly accelerated and all animals received fewer unavoided shocks. A quantitative index of avoidance efficiency revealed that all Ss' behavior was least efficient in avoiding shock during the fixed ratio punishment condition and was most efficient during the delivery of non-contingent shock.
