Numerals indicate the mean percent error obtained on trials 1–4 for problems learned in the last 5 of 20 sessions administered before surgery (preoperative learning) and the last 5 of 20 sessions administered after surgery (postoperative learning). A1–A4 are monkeys with excitotoxic amygdala lesions.
↵F2-a Did not reach criterion. Used mean score for last 15 sessions before operation.
