Document Summary
Operant conditioning: associating a response with a consequence. Child learns to repeat behaviors (saying please ) which were followed by desirable results (cookie) Child learns to avoid behaviors (yelling gimme! ) which were followed by undesirable results (scolding or loss of result) Edward thorndike placed cats in a puzzle box; they were rewarded with food (and freedom) when they solved the puzzle. Thorndike noted that the cats took less time to escape after repeated trials and rewards law of effect: rewarded behaviors are more likely to occur. Operant chamber allowed detailed tracking of rates of behavior change in response to different rates of reinforcement. Can change behavior (increase and decreas) based on different responses of reinforcement. Reinforcement: any feedback from the environment rhat makes the behavior more likely to occur: positive reinforcement: you add something desirable (praise, negative reinforcement you take away something unpleasant (no dishes)
