Age-based performance on the Wake Forest Maze Task (WFMT) and Delayed Response (DR) task (a) Middle-aged (Tukey p=0.022) and older (Tukey p=0.023) monkeys completed more WFMT levels than did the oldest vervets (ANOVA: F(2,26)=5.917). (b) Pearson correlations between the total number of WFMT levels completed and percent correct in the DR task (20 second delay). Overall, performance in the WFMT agreed well with performance in the DR task (Rho=0.610; p=0.001) (Frye et al., 2021).
