Table 1.

The scores are percent correct responses at each delay interval during baseline and after huperzine A administration on Task 1 and Task 2. X represents mean values averaged either across subjects within a delay or across delays for each subject. Within-subject analysis of variance with repeated measures indicated no significant effects of treatment, delay, or interaction between these two factors for either Task 1 or Task 2 (all ps>0.05).
