Figure 4. Slowing was due to experience not time.

Figure 4

(a) Example behavior and (b) all data for replay durations during a single pass of a novel track, subsequent rest, and a second exposure to the track with multiple passes. Replays did not increase in duration during rest (One-tail test: N =228; Duration: R = −0.14, P = 0.98), c, P = 2.4e-4). Two-way ANOVA: main effect of group F(1,507) = 4.7, P = 0.03, main effect of pass F(1,507) = 9.9, P = 2.0e-3, interaction F(1,507) = 14.9, P = 1.3e-4.

(c) Example behavior and (d) all data for replay durations during, and in rest following, a multiple-pass session on a novel track. Replays of the novel track (Run 1) increased in duration with continued experience on the track (One-tail test: N = 216, Duration: R = 0.20, P = 0.0019), but did not continue to increase in duration during subsequent rest (One-tail test: N = 79, Duration: R = 0.054, P = 0.32). Two-way ANOVA: main effect of group: F(1,294) = 5.6, P = 0.019, main effect of pass: F(1,294) = 7.69, P = 5.9e-3, interaction: F(1,294) = 5.5, P = 0.020. All data show mean ± S.E.M. Correlations are Pearson’s correlation values. *** P < 0.001, ** P < 0.02, * P < 0.05
