Document Summary

Response-reinforcement bond is critical response that get reinforced are more likely to occur. Schedules of reinforcement: continuous reinforcement --> cr. Reinforce every correct response: fixed ratio --> fr. Fr5 --> reinforce every 5th correct response ---> fr 1 = cr: variable ratio --> vr. On average, reinforce every nth correct response: fixed interval --> fi. Reinforce first correct response after a certain time has elapsed: variable interval --> vi. Reinforce first correct response after a certain time has elapsed on average. Experience with extinction maintains responding because reinforcement is e. g. fi 1 minute, reinforce first correct response after 1 minute unpredictable. Vr or vi are most resistant to extinction. Involves formation of cognitions the internal processing of information (thoughts, beliefs, etc. ) Traditional s - r approach can"t explain very well. Cs (light) --> cr (fear: operant conditioning. Termination of light acts as negative reinforcer for the jump response. Given some event, one outcome is more likely to occur than another.
