Document Summary

Thorndike (1911: b. f. skinner found a limitation to thorndike"s method for testing the law of effect . Instrumental learning: the behaviour is instrumental in determining what happens: note the important difference between these procedures and those used by pavlov: Pavlov: the subject has no control over events, but responds to them. What is partial reinforcement, and how to the different partial reinforcement schedules affect behaviour: partial reinforcement in extinction effect (pree) In lewis & duncan"s experiment, they observed gamblers. It is when an individual is rewarded on some, but not all, trials it is only reinforced at certain intervals or ratio of time, instead of reinforcing the behaviour every single time. Immediate (high contiguity) the faster the reinforcer is given after the response, the better; contiguity = close in time: contingent given if the response is made; withheld if the response is not made, valuable.
