Q

Liljeholm and O’Doherty discuss evidence that cues that signal reward delivery - even though the reward is not contingent on whether or not an instrumental action is performed - can nevertheless invigorate instrumental performance, a phenomenon termed Pavlovian-instrumental transfer (PIT). Which of the following is consistent with the account of this phenomenon as summarized by Liljeholm and O’Doherty?

A. Dorsal stratal function, but not ventral striatal function, has been linked to invigorated performance on instrumental tasks associated with non-contingent reward cues (PIT).

B. Dorsal stratal function, but not ventral striatal function, has been linked to invigorated performance on instrumental tasks associated with motivational state.

C. Ventral striatal function has been linked to invigorated performance on instrumental tasks associated with non-contingent reward cues, but only for very specific reward-related behaviors (specific PIT).

D. Ventral striatal function has been linked to invigorated performance on instrumental tasks associated with non-contingent reward cues, both for general behaviors (general PIT) and for specific reward-related behaviors (specific PIT).

Q

Which of the following is consistent with the “associative” account of functions of the dorsal striatum favored by Liljeholm and O’Doherty?

A. The dorsomedial striatum (caudate) is more strongly involved in encoding associations with goal-directed instrumental actions, while the dorsolateral striatum (putamen) is disproportionately involved in encoding stimulus-response (habit) associations.

B. The greater involvement of dorsomedial (than dorsolateral) striatum during early stages of motor sequence learning than during the later stages is likely due to its greater role in motor learning than in motor performance.

C. The dorsolateral striatum (putamen) is more strongly involved in encoding associations with goal-directed instrumental actions, while the dorsomedial striatum (caudate) is disproportionately involved in encoding stimulus-response (habit) associations.

D. The greater involvement of dorsolateral (than dorsomedial) striatum during early stages of motor sequence learning than during the later stages is likely due to its greater role in motor learning than in motor performance.

Q

Which of the following is consistent with the “associative” account of functions of the ventral striatum favored by Liljeholm and O’Doherty?

A. The ventral striatum is disproportionately involved in learning of new reward-related behaviors and the dorsal striatum is disproportionately involved in performance of previously learned reward-related behaviors.

B. The dorsal striatum is disproportionately involved in learning of new reward-related behaviors and the ventral striatum is disproportionately involved in performance of previously learned reward-related behaviors.

C. Ventral striatum is involved in the learning as well as in the performance of reward-related behaviors that are dependent upon instrumental response-reward associations.

D. Ventral striatum is involved in the learning as well as in the performance of reward-related behaviors that are dependent upon Pavlovian stimulus-reward associations.
