Document Summary
Operant conditioning: organisms operate a certain way, (cid:862)la(cid:449) of effe(cid:272)t(cid:863, b. f. skinner (evangelion for behavioral psychology)- worked with pigeons, all behavior is shaped and maintained by its consequences. Behavior that is reinforced tends to recur, and behavior that is not reinforced tends not to be repeated. All we know if what we reinforce: positive reinforcement: anything that, when presented, increases the rate of the (cid:271)eha(cid:448)ior (cid:449)he(cid:374) it"s taken a(cid:449)ay, punishment: anything that decreases behavior when presented. Very ineffective way to condition a behavior: skinner could train pigeons to hit a target. Wwii- pigeons out-performed any other available missile guidance system. Us government was literally about to put pigeons into bombs to guide them to targets. Schedule of reinforcement: variable ratio: every x actions, reinforcement occurs. **highest rate of reaction (most effective) ** Interval: after every set amount of time reinforcement occurs. Variable intervals work better than set intervals. Generalization: driving a car; can be unlearned with other trainings.
