The critical finding of Jacobsen's experiments (1936) was ________.
A) bilateral lesion of PFC did not impair recall in delayed response tasks, but they did when no delay was interposed
B) bilateral lesion of PFC impaired recall in delayed response tasks, but not recall without delay
C) bilateral lesion of occipital cortex impaired recall in delayed response tasks, but not recall without delay
D) bilateral lesion of medial temporal cortex impaired recall in delayed response tasks, but not recall without delay

Question

Quizplus · Accepted Answer

Jacobsen's experiments in 1936 demonstrated that bilateral lesions of the prefrontal cortex (PFC) impaired the ability of monkeys to perform delayed response tasks, indicating the critical role of the PFC in working memory and the management of temporal information. Recall without delay was not significantly affected, highlighting the specific impact of these lesions on tasks requiring the maintenance of information over a period of time.
