Document Summary

Number and spacing of extinction trials: is to conduct more extinction trials. The simplest way to increase the impact of extinction numbers of extinction trials produces a more profound decrease in conditioned responding. Another important variable in extinction is the spacing of trials. in time = massed extinction trials may produce a rapid immediate decrement in responding, the conditioned. Presenting the stimuli spread out in time = spaced behavior is likely to return with a period of rest (spontaneous recovery) or a change in context (renewal). Such relapse is troublesome for exposure therapy, making spaced exposure trials preferable: immediate vs delayed extinction: requires a process called memory. This takes time, which raises the possibility that introducing extinction been fully consolidated might change the memory and promote extinction performance. Conducting extinction trials immediately after the acquisition produces a more rapid loss of conditioned behavior than conducting extinction one day later. conditioned behavior is deceptive because with immediate extinction the.
