Learning Revision Classical Conditioning • US, UR, NS, CS, CR • Acquisition, Extinction, Generalization, Discrimination • Types of conditioning: – – – – Delayed – NS – UCS. Trace – NS – time passes – UCS. Simultaneous – NS+UCS Backward – UCS – NS • Aversive conditioning Classical conditioning • Higher order conditioning • Biology and Conditioning – Garcia, Koelling Operant Conditioning • • • • Edward Thorndike – Law of effect Skinner – Reinforcement and punishment Shaping and Chaining Reinforcers: – – – – Primary Secondary Generalized Token economy • Premack principle • Learned helplessness Schedules of partial reinforcement • Fixed-ratio – reinforce behavior after a set number of responses. (give a student mark after 3 correct answers). • Variable-ratio – reinforce after an unpredictable number of responses (sometimes give a mark after 2 answers, sometimes 4, etc) • Fixed-interval – reinforce the first response after a fixed time period (Grading students every week depending on their work). • Variable-interval – Reinforce the response after varying time intervals (Grading students in 2 days, then in 3 days, then in 5, etc). Cognitive learning • Pavlov – Contiguity model, based on pairing of two things. • Rescola – Contingency model, Learning is based on our congitions. Types of Cognitive learning • Observational learning – Bandura, bobo doll. • Latent learning – Tolman, learning becomes obvious when you give reward for it. • Abstract learning – learning concepts. • Insight learning – Kohler, sudden learning. Biology • Mirror neurons • Conditioned taste aversion • Preparedness • Keller & Breland – Instinctive drift
