PS261 Chapter Notes - Chapter 10: Operant Conditioning, Classical Conditioning, Reinforcement
Document Summary
Avoidance procedure make specific response to prevent aversive stimulus. Punishment positive contingency, response produces aversive outcome. Avoidance behaviour: origins of the study of avoidance behaviour. Classical conditioning procedure and procedure that had instrumental avoidance component added. Studies conducted proved that avoidance conditioning is different from standard classical conditioning: the discriminated avoidance procedure. Investigators concerned with importance of warning signal in avoidance procedures and relation of warning to us and instrumental response. If subject makes target response before shock is delivered, cs turned off. If subject fails, scheduled shock appears until response occurs. When animals shuttles back and forth between two compartments to avoid aversive stimuli. Two-way avoidance moves in different directions on successive trial. One-way avoidance starts trial on same side and always moves in the same direction, to other side. One-way avoidance is easier to learn: two-process theory of avoidance. Absence of aversive stimulus the reason that avoidance responses are made. Not getting something can hardly qualify as rewarding.
