If S failed to respond on all of the the hypothesis that 5" learned that first five trials, 61 was moved to the other shock termination was independent of side of the shuttle box. These dogs did not appear to the "Yoked" control group during their benefit from the barrier-jumping—shock initial exposure to shock only in their termination contingency. The shock intensity was 6. Seven days later, those Ss in this group which showed interference with escape responding in the interference effect received 10 more the shuttle box. Thus each 5" in the number of failures to escape shock, and "Yoked" control group received a series of shocks of decreasing duration totaling to the percentage of Ss which failed to sec. The remaining group, see below over the four blocks 27 dogs were randomly assigned to three of 10 trials. The CS-US interval was 10 sec.

This cage was not completely sealed and they just required jumping over the bar to escape the shock.
