Avoidance Apparatus

Two experiments were conducted to estimate the retention of response-prevention effects using massed vs distributed treatments in a model of animal avoidance-learning. In Exp. I, 120 rats were trained to avoid shock in a one-way platform avoidance apparatus. Groups received response-prevention treatment or nontreatment in a 36-min. massed session or in several sessions distributed over a four-day period. In Exp. II, 160 rats were given two trials of escape training in a one-way shuttle box. Groups received response-prevention treatment or nontreatment in a 24-min. session of massed or distributed treatments delivered in one day. Subjects in both studies were tested using a passive-avoidance paradigm immediately following treatment, 24 hours later, and 30 days later. Analysis showed that response-prevention treatments were effective in reducing avoidance behavior and there were no significant differences in retention of avoidance associated with massed vs distributed response-prevention treatments. Implications for animals and humans are discussed, and researchers are encouraged to change from a criterion training procedure to an escape procedure since the latter is a closer analogue to the human condition.

Treatment Interaction

Two experiments investigated the effect of shock intensity on escape learning in a straight alley (Exp. I) or avoidance learning in a one-way shuttle box (Exp. II) in operated control (OC) rats or rats under bilateral spreading depression (BSD). Results of Exp. I using 0.6-, 1.2-, and 2.4-ma. shock indicated no interaction of shock level with cortical treatment and that BSD Ss were inferior to OC Ss. A low level of shock resulted in poorer performance than intense shock. Results of Exp. II using 0.4- and 2.0-ma. shock indicated a shock by cortical treatment interaction. 0.4-ma. BSD Ss were inferior in latency to 2.0-ma. BSD Ss and 0.4-ma. OC Ss.

The One

Wistar, Sprague-Dawley and Fischer rats were tested for general activity levels and for three different types of avoidance learning. No strain differences were observed for general activity or for the number of trials to learn a conditioned avoidance response (CAR) in the one-way shuttle box. The Fischer strain avoided shock more than the Wistar strain which in turn avoided shock more than the Sprague-Dawley strain during the acquisition of the CAR and nondiscriminated avoidance response in the two-way shuttle box.

Escape Responses

Rats were given 0, 8, 50, and 100 fear conditioning trials prior to shuttle-box avoidance learning. The fear conditioning trials resulted in: (a) an increased latency of escape responses during the initial avoidance training, (b) a greater variability of avoidance learning scores, and (c) a slight, but not statistically significant, improvement in avoidance learning. These results are attributed to fear being associated with the buzzer and to the establishing of favorable and incompatible responses to the grid shock.
