The effects of various punishment-escape events upon subsequent choice behavior of rats.

Abstract

3 studies were presented concerning the recent evidence that increased approach tendencies develop to cues associated with the reduction of punishment. All studies were conducted with rats which were shocked in an alley while running. The results of the 1st study indicated that Ss increased their tendency to approach cues contiguous with escape from shock or fear. The 2nd study showed that approach tendencies, acquired by rats in a shock and hunger reduction situation, were not appreciably affected by changes in the drive conditions during testing. The 3rd study showed that shock reduction and hunger reduction had equal effects on approach tendencies and these drives combine in the development of these tendencies.
