Tylerâs grandmother, Rose, has been receiving e-mails from Tyler every day for many years. In anticipation of his e-mails, she checks her inbox more than once in a day. However, since Tyler has started college, the e-mails have stopped. As a result, Rose checks her e-mail only every few days. If this pattern continues, Rose will completely stop checking her e-mail. In classical conditioning, this is known as . a. Acquisition b. Spontaneous recovery c. Renewal d. Extinction

Extinction

Explanation: Extinction literally means a state of non-existence of something due to gradual decline over time. Extinction also takes the same pattern in classical conditioning whereby a conditioned response gradually fades away or declines over time due to non-reinforcement of the conditioned behavior. In the scenario above, A behavior which Tyler used to perform everyday also triggers a similar response from her grandmother Rose, however, since Tyler has regressed in the reinforcement of her behavior( sending mails), the response from her mother also declines(checking mailbox), therefore if the non reinforcement continues on Tyler's path, Rose will completely stop checking her mail. Once this happens, Extinction has occurred.
