title: Performance of healthy subjects and patients with resection from the anterior temporal lobe on matched tests of verbal and visuoperceptual learning.
abstract: We examined the equivalence of three matched forms of the Rey Auditory Verbal Learning Test (RAVLT) and three parallel forms of a new nonverbal analog, the Aggie Figures Learning Test (AFLT). One hundred and fourteen healthy subjects, primarily college students, were administered corresponding forms of the two tasks. For both tasks the three forms proved to be well-matched; as well, overall performance on the RAVLT was comparable to that on the AFLT. The two tasks were also administered to 23 patients with anterior resection from the left or right temporal lobe (ATL). Findings showed that right ATL patients were significantly impaired on the learning trials of the AFLT as compared to their learning on the RAVLT; they showed little forgetting of figures or words over a 20-min delay interval. By contrast, left ATL patients showed severe forgetting of words as compared to figures, but their learning curve for the RAVLT did not differ from that on the AFLT.
