Behavioral psychologists apprehend that conditioned fear responses to a
tone previously paired with a shock diminish, if the tone is repeatedly presented
without the shock, a process known as extinction. Since Pavlov it has been
Line hypothesized that this extinction does not erase conditioning, but forms a new
(5) memory. Research has now demonstrated that destruction of the infralimbic
cortice blocks recall of fear extinction, indicating that it might store long-term
extinction memory. Infralimbic neurons recorded during fear conditioning and
extinction fire to the tone only when rats are recalling extinction on the
following day, and rats indicating the least fear responses also demonstrate the
(10) greatest increase in infralimbic tone responses. Conditioned tones paired with
brief electrical stimulation of infralimbic cortex elicit low fear responses in rats
that have not undergone extinction. Thus, stimulation resembling extinction-
induced infralimbic tone responses is able to simulate extinction memory. [br] It can be inferred that a rat with its infralimbic cortices destroyed would respond which of the following ways to a tone previously conditioned to induce a fear response? Ⅰ. It would demonstrate fear if extinction had occurred the previous day. Ⅱ. It would demonstrate fear if extinction had occurred earlier than the previous day. Ⅲ. It would demonstrate fear even if extinction had never occurred at all.
