Surprising effects sometimes occur when previously conditioned stimuli are presented together. For example, Woodbury (1943) trained dogs to lever press for food in the presence of a low-pitched buzzer sound and a high-pitched buzzer sound. In the presence of either of these stimuli, lever pressing was reinforced with food, but when both signals were presented together, food was never delivered when lever pressing occurred. The dogs consequently learned to lever press when either of the two signals were presented separately but refrained from responding when both signals were presented together. This finding is a little odd, since one would expect, if both the low-pitched and high-pitched buzzer sounds produce responding, that when both sound stimuli are presented together, responding should still occur. What appears to occur, however, is the formation of a distinct compound configuration composed of elements derived from both stimuli but sufficiently different from each to be easily discriminated and associated with the absence of reinforcement.
