Document Summary
Operant conditioning (skinner) voluntary responses learning through consequences. Three components: stimulus (s, response- voluntary response, consequence: Positive reinforcer(sr+): when something pleasant is added to the situation and this increases the probability of the response re-ooccuring (ex. Getting an a on one test, probability of studying hard for the next test increases, but there is no guarantee) The reinforcer may not work for every individual, you have to know what the individual actually likes. Positive reinforcer: reward delivered after the desirable target behavior. Primary reinforcer: naturally reinforcing and satisfies a biological need (food, water, sex) Conditioned or secondary reinforcer: a s that becomes a reinforcer through its association with a primary sr+. Conditioned reinforcers usually learned (praise, money, good grades) Ex: if you are always the one who gives your dog food, then you become the secondary reinforcer. Factors that increase the effectiveness of an sr: magnitude of the sr, immediacy of the sr, scheduling or pattern of reinforcement i) ii)
