Operant conditioning of brain steady potential shifts in man
Biofeedback and Self-Regulation
|June 1, 1979
Abstract:
Steady potential shifts (SPS) recorded from the scalp were conditioned operantly by visual and acoustical feedback. Three groups of seven subjects were each tested with a different response-reinforcement contingency: positive reinforcement for a positive SPS after a cue stimulus, positive reinforcement for a negative SPS after a cue stimulus, and noncontingent reinforcement. The steady potential shifts learned under these three conditions differed significantly. Negative shifts were associated with subjective feelings of activation, positive shifts with inactivation. Cortical genesis and possible artifacts are discussed.
