Document Summary
E. l thorndike described the law of effect: behaviors are selected by their consequences; Behavior having good consequences tends to be repeated. Behavior that leads to bad consequences is not repeated: according to thorndike and others, Learning involves an association between a stimulus and response. Developed a highly efficient conditioning chamber (skinner box) that allowed for conditioning and automated behavior measurement: typically contains bar that delivers food when pressed, food dispenser, and light that signals when reward is forthcoming. Positive reinforcement : pleasant stimulus is given to increase the probability of response. Negative reinforcement : unpleasant stimulus is removed to increase the probability of response. Dinging noise when you don"t put on your seatbelt. Punishment : unpleasant stimulus is given, or pleasant stimulus is taken away, to decrease the probability of response. Going into timeout so you can"t play. Positive punishment tends to be ineffective: tells organism what not to do. Rather than what to do: creates anxiety.
