PS261 Chapter Notes - Chapter 10: Reinforcement, Proprioception
Document Summary
In the two process theory, reinforcement for avoidance response is assumed to be provided by the reduction of conditioned fear (negative reinforcement, take away something bad) Other treatments have proposed that avoidance procedures provide for positive reinforcement of the negative response, others have said neither negative nor positive reinforcement is important. Positive reinforcement through conditioned inhibition of fear or conditioned safety. Response feedback cues: stimuli produced by making a skeletal response ex pressing lever. Response feedback stimuli may acquire conditioned inhibitory properties and become signals for absence of aversive stimulation (safety signals) According to safey signal hypothesis, safety signals that accompany avoidance responses may provide positive reinforcement for avoidance behaviour. The act of making the instrumental response provides spatial, tactile, and proprioceptive stimuli that inevitably accompany the avoidance response and become safety signals. Predicts that introducing an explicit feedback stimulus will facilitate the learning of an avoidance response.
