Learning and Conditioning Notes Classical Conditioning 1. Basic Idea (a) learning by implicit associations between unrelated stimuli (b) emotional and physiological responses 2. Model (a) unconditioned stimulus, unconditioned response (b) neutral stimulus/conditioned stimulus, conditioned response (c) Pairing the unconditioned stimulus with a neutral stimulus causes the neutral stimulus to evoke the unconditioned/conditioned response (d) Three phases i. acquisition ii. conditioned phase iii. extinction 3. Pavlov (a) trained dogs to salivate at the sound of a bell by pairing the bell with food (b) discovered that a conditioned response will diminish if the US is separated from the CS (extinction) 4. Watson/Raynor (a) induced a panic response in a child by pairing white rats with a loud, startling sound (b) determined that emotional responses can be conditioned (c) Stimulus generalization i. during acquisition, a conditioned response to the CS and to “related” stimuli such as the environment in which conditioning takes place (d) Stimulus Discrimination i. during extinction, separation of the CS from related stimuli, resulting in less frequent CR 5. Extinction (a) Separation of CS from US results in diminished CR, re-introduction of US strengthens response (b) Extinction must occur in the presence of the CS 6. Therapeutic Applications (a) counter-conditioning – Mary Cover Jones i. re-associating the tainted CS with a positive emotional experience, in an attempt to replace the anxiety response ii. may not be effective (b) Systematic Desensitization i. anxiety hierarchy A. ranking anxiety-inducing stimuli and approaching them one at a time in a systematic manner ii. progressive relaxation A. training techniques for anxiety management and distress tolerance iii. Using these techniques to expose client to the CS while allowing them time to work through the anxiety and reduce their stress (c) Total Immersion i. Exposing the client to the worst case scenario so that they experience panic, but are unable to withdraw from the situation, thereby weakening the CR 7. Biological Preparedness (a) certain associations are more easily trained than others, especially those having to do with survival and which have a long evolutionary history i. heights, water, snakes, spiders, certain smells and tastes, lightning, etc ii. aversive conditioning seeks to pair an aversive response with a CS in order to induce avoidance of the CS iii. Also occurs in cases of food poisoning 8. Cognitive Factors (a) Reliable signals i. CS is a “signal” which alerts the client to the fact that the US “follows;” extinction is then a matter of the client’s beliefs about the relationship between US and CS Operant Conditioning 1. Basic Idea (a) Changing overt behaviors (operants) by understanding and manipulating the consequences of the behavior; positive consequences strengthen behaviors and negative consequences weaken them 2. Model (a) antecedent (context) (b) behavior (c) consequence (reinforcement or punishment) 3. James, Hall, Thorndike (a) James: Functionalism – behavior is adaptive; successful behaviors survive (b) Hall and Thorndike i. use of behavioral principles in education; Thorndike’s “satisfying state of affairs” 4. Skinner and Operant Conditioning (a) Describes and demonstrates the impact of different reinforcers in training animal and human behavior 5. Types of Reinforcement/Punishment (a) Positive Reinforcement (b) Positive Punishment (c) Negative Reinforcement (d) Negative Punishment 6. Schedules of Reinforcement (a) Extinction of a conditioned behavior depends on the training method (b) Continuous Reinforcement i. fast learning, fast extinction (c) Partial Reinforcement i. slower learning, slower extinction ii. Fixed Ratio and Interval iii. Variable Ratio and Interval 7. Shaping (a) Step-by-step rewarding of behaviors that approach the desired goal (b) useful for animals, children, adults who are resistant to behavioral change (c) covert, rather than overt 8. Therapeutic Techniques (a) Token Economies (behavior management) i. use of scheduled rewards to change behavior ii. especially useful with negative reinforcement/punishment loops (b) EX/RP (anxiety and phobias) i. exposure to the anxiety-provoking stimulus followed by response prevention; teaches distress tolerance while also replacing maladaptive anxiety responses Observational Learning and Social Learning Theory 1. Observational Learning (a) Basic Idea: vicarious reinforcement i. Bandura discovers that reinforcement can occur through other people (models) and not just as a result of things that happen to us directly (b) modeling i. models must be relatable. Effectiveness of training depends on the client being able to place themselves in the model’s shoes ii. implications for advertising? (c) importance of social influence i. advertising ii. crowd management iii. crime deterrence iv. promulgation of social norms 2. Social Learning Theory (a) reciprocal determinism i. social, behavioral, and cognitive factors all contribute to which behavior is selected (b) Integration w/r/t Operant Conditioning i. values A. reinforcers are only successful if the client values them; a reinforcer may be positive or it may be a punishment depending on who the client is ii. beliefs A. beliefs about the relationship between reinforcers effect client behaviors (see below) B. The way we INTEGRATE all of this information determines more about our behavior than punishment and reward alone (c) Rotter, Seligman, Linehan, Bandura i. Rotter: locus of control ii. Bandura: self-efficacy iii. Seligman: learned helplessness iv. Linehan: Dialectal Behavioral Therapy (d) Cognitive Behavioral Therapy i. Addresses the integrative processes by which we understand how our behavior is reinforced in a broader social setting.
