Document Summary

Conditioning in which behavior is associated with consequences. Law of effect: rewarded behaviors more likely to be repeated. Shaping: gradual process of reinforcing organism for behavior that gets closer and closer to the desired. Reinforcer : something that comes after a behavior that increases likelihood of performing behavior again. Best reifnorvers depend on the organism, circumstances, etc. Positive reinforcement: desired reinforcer given after behavior (increases future behavior) Unpleasant stimulus removed following desired behavior (increases future behavior) Human examples: taking aspirin for headache, fastening seatbelt to stop dinging noise. Primary reinforcer: natural reinforcers (don"t need to be learned) aid survival. Secondary reinforcers: paired with primary reinforcer becomes reinforcer itself. Mischel et al (1989) 4 year olds given choice: small amount of candy or large amount later. Choosing to wait social competence, higher achievement in. 4 schedules of partial reinforcement adolescence, better sat scores. Partial reinforcement slower learning, but slower extinction.
