Goldfish, run in a Y-maze, with the simultaneous presentation of a cue associated with shock and a second cue associated with safety (no US), acquired a decided preference for the safe cue. These data are interpreted as representing a clear demonstration of stimulus-specific conditioned avoidance. Because earlier research has been challenged by unusual control performances, this instrumental learning conclusion is hesitantly drawn.
