Negative reinforcement is the removal of an aversive condition. Describe two important differences between classical and operant conditioning. Classical conditioning controls more involuntary bevaviors of the autonomic nervous system. Operant controls more of the somatic. Distinguish between stimulus discrimination and stimulus generalization.
Discrimination means that the more similar the stimulus the more likely the response.
Generalization means that similar as well as identical stimuli can elicit a response. Explain the process of extinction. Extinction results from removal of source of learning Certain reinforcement schedules are susceptible to extincion. Discuss the relationship between spontaneous recovery, external disinhibition, and extinction. Hebb thought of learning as a permanent facilitation of conductance in and between cell assemblies to form phase sequences.
