Evidence for a unique cue in positive patterning

Peter C. Holland, Harvey Block

Research output: Contribution to journalArticlepeer-review


Rats received Pavlovian positive patterning training in which a simultaneous tone + light compound was reinforced with food and the light and tone elements were separately nonreinforced. Solution of the discrimination was accompanied by the emergence of a unique response topography in the presence of the compound. Control rats that received reinforced compound presentations but no separate nonreinforced presentations of the elements acquired behaviors characteristic of light and tone stimuli separately paired with food, but did not acquire the unique response topography acquired by the rats that received positive patterning discrimination training. These data supported earlier claims that the solution of such discriminations involves the conditioning of a stimulus unique to the compound stimulus.
