Summary:
Two groups of rats received training and testing in learning situations designed to induce perseveration. One task involved discrimination training on one bar of a two-bar Skinner box and a subsequent shift of reinforcement to the opposite bar. The second task was a maze-learning one in which the training route was blocked after 40 trials at a point just before the entrance to the goal box. Thereafter, access to the goal box was possible only through a shorter, but not previously reinforced route. The third task involved escape training through one door of a four-door shock compartment. After 40 trials, the training door was locked and S was permitted to escape shock only through one of the three previously-locked doors. In each of the three tasks, indices of initial learning and perseveration were selected, and within-subject comparisons were made for both initial learning and perseveration across tasks. Within each task there was a comparison of the initial learning measures to those used to define perseveration. Finally, one of the groups was given conditioning and extinction sessions in a single-bar Skinner box. The extinction measure was compared with perseveration measures in the other tasks. Four hypotheses were stated. These were that between tasks perseverative measures would be positively related; that between tasks initial learning measures would be positively related; that within each task initial learning and perseveration would be neeatively related; and finally that extinction in the single-bar Skinner box would have a positive relationship to measures of perseveration in the other tasks. Only the last two hypotheses were supported and this support was not uncontradicted. Also~ in the case of the extinction-perseveration comparisons, none of the supporting evidence reached significance at the .05 level of confidence.
