This represented a highly significant difference (two-way analysis of variance (ANOVA) with factors young/adult stage, and individual monkey; F 1,304 =189.7 for main effect of stage, P =7.2 × 10 −34 ).

In contrast, the difference in cue period activity failed to reach significance ( t -test, t 229 =1.74, P =0.08).
of the population tuning curves was 35.4° in the young and 27.6° in the adult for the cue period, a significant difference (permutation test, P <0.005), and 28.1° in the young versus 24.2° in the adult for the delay period, though the latter contrast did not reach statistical significance (permutation test, P >0.1).
