摘要

Signaled avoidance learning in crayfish (Procambarus clarkii) was investigated when the crayfish were not confined, by indexing two types of locomotive movement to the escape compartment. Mild shocks, which induced tail flipping in the crayfish, and light illumination were used as unconditioned and conditioned stimuli, respectively. In Experiment 1, two groups of crayfish were trained in a one-way shuttle box. The crayfish in Group Forward were placed in the start compartment facing the escape compartment and they were able to escape/avoid shocks by walking forward, while the crayfish in Group Backward were placed in the compartment facing the opposite direction and they were able to escape by tail flipping. Avoidance learning was achieved only by walking, and not by tail flipping despite the fact that consistent tail flipping allowed the crayfish to avoid shocks. In Experiment 2, the experimental conditions were switched by using the ABA design. In this experiment, we confirmed that avoidance behaviorwas restricted to walking. These results are readily explained by the behavior systems approach.
