Why are some behaviors more resistant to extinction? • Partial reinforcement effect (PRE) • Mower & Jones’ rat study supports the theory that behavior on intermittent schedules is more resistant • Contrary to Thorndike’s law of effect—behavior is a function of its consequeces
Why does the PRE exist? • According to the discrimination hypothesis… • It simply takes more time for the subject to realize that reinforcement has stopped when a schedule is intermittent.
According to the frustration hypothesis… • Subjects learn to become frustrated before receiving reinforcement. • This makes the frustration experienced during extinction more tolerable and even a cue for the behavior.
According to the sequential hypothesis… • Reinforcement actually becomes the cue for behavior in CRF • Sequence (involving times with no reinforcement) becomes cue in intermittent reinforcement
According to the response unit hypothesis… • The unit of measurement for a behavior needs to be redefined to reflect how often the behavior must occur to be reinforced. • When the new unit is considered, the rate of behavior during extinction actually declines.
What is the matching law? • You can predict a subject’s choice of behavior based on the reinforcement that is provided. • Subject’s spend more time on schedules that payoff better.
