The purpose of this study was to determine if conditioned suppression as demonstrated by Estes and Skinner could be replicated in the chimpanzee using electrical stimulation of the brain as both aversive and pre-aversive stimuli. Stimulation was delivered by means of a miniature multichannel stimulator attached to the cranium and activated by radio. A fixed intensity pre-aversive stimulation and several intensities of aversive stimulation were superimposed on a FR 30 schedule for food reinforcement. The progress of this experiment had much in common with the outcome of a classical Estes-Skinner paradigm.
