Further, whereas the performance of young marmosets was stable across reversals, the performance of aged marmosets worsened across the reversals as revealed by a strong positive correlation between reversal number and errors to criterion that approached significance [ Fig. 3 C ; Young, r s (3) = 0.03, p = 0.68; Aged, r s (3) = 0.90, p = 0.08].
