Performance Decline

A total of 136 rats were employed in three experiments which assessed the effect of methamphetamine hydrochloride on passive avoidance behavior, on the energizing properties of non-reward in the double runway, and on the decrement in runway performance, which follows a drop in reward value. The drug increased passive avoidance behavior, did not alter the effects of non-reward in the double runway, and reduced the performance decline occasioned by the reward decrement. These results do not support the hypothesis that amphetamines increase emotional reactions; increased passive avoidance behavior resulted because the drug decreased consummatory behavior. The reduction in the performance disruption following the reward shift is consistent with the position that the drug decreases freezing behavior.

Group Weights

27 female rats received 96 acquisition and 16 post-shift trials in an L-shaped double runway. In acquisition food was present both in the first (G1) and the second (G2) goal boxes, but was omitted from G1 on half the post-shift trials. The usual frustration effect (FE), in which response speeds in the second alley are faster following absence as compared with presence of reward in G1, appeared in each of 2 drive (D) groups. However, the magnitude of the FE was greater in the high D group (weights maintained at 80% of initial ad lib. level) than in the low D group (weights at 90%).

The Absolute

Four experiments are reported which involved relative qualitative (Exps. 1 and 2), relative quantitative (Exp. 3), and absolute quantitative (Exp. 4) sucrose-solution incentive reductions in the first goal box of a double runway. In the three relative experiments, different GB1 amounts (.50 cc vs .10 cc) or concentrations (32% vs 8%) of sucrose did not affect pre- or postshift locomotion speeds in either runway. In the absolute study, RW1 speeds varied directly, and RW2 speeds varied inversely, with GB1 reward magnitude (.50 vs NR). Postshift RW2 speed changes favored a demotivation rather than a frustration interpretation of incentive change.
