Document Summary

Likehood of a response by following behaviour with reinforcement (or punishment) Uses a respondent behaviour: one that automatically to some stimulus. A behaviour (arbitrary) is being associate with a stimulus. Behaviour operates on (or affects) the environment by producing consequences (rewarding or punishing) Association between behaviour and rewards stamps in/ reinforces the operant behaviour and learning is strengthened. Strengthening of a behaviour occurs when a reward follows. Get an initial (baseline) level of bar press. Find rat will learn to press bar to get food. Bar press = operant behaviour or operant or operantly conditioned response . Reinforcer = anything which strengthens rate of the response. Generalization = operant will occur in presence of similar stimuli. Discrimination = can be learned use 1 stimuli where reinforcement occurs and another where reinforcement does not occur. Operant strength = strength of the association between operant and reinforce. Upon extinction if # of responses increase = higher operant strength.
