Sizeable Difference

Avoidance behavior in wheel box and shuttle box were compared in two experiments which tested the same rats in both apparatuses. Performance in the shuttle box was superior to performance in the wheel box for both male and female Sprague-Dawleys. The corresponding differences for the Long-Evans, though not significant, were in the opposite direction. Reactivity to shock was considered a possible explanation for the sizeable difference between the two strains in shuttle responding. High reactivity to shock was thought to inhibit avoidance learning in the shuttle but to facilitate learning in the wheel. The results, together with previous work, suggest that both apparatus variables and organismic variables, and their interaction, are important in avoidance behavior.

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.

Mice were given 30 practice trials or 30 arbitrary shocks in a runway at 17, 23, 40, or 55 days of age. Performance was directly related to age, with adult Ss showing the greatest improvement during the 30 trials. At 85 days of age, Ss were run to criterion in the same runway. Results indicated that (1) groups receiving prior shock or practice in the runway were significantly better than controls with no prior runway experience; (2) Ss receiving prior practice were not significantly different from Ss receiving equal amounts of shock without practice; (3) animals receiving prior experience at 23 days of age were superior to other groups on the adult avoidance learning task. Critical periods for learning and implications of a multi-factor theory to account for the effects of early experience on avoidance behavior are discussed.

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.
