Decoding accuracy for this stimulus, which briefly appeared on the screen early in the delay period, was similar across conditions (two-way repeated measures ANOVA with ROI and task condition as factors: main effect of ROI: F(13,65) = 13.4, p<0.001; main effect of task condition: F(1,5) = 2.164, p=0.193; ROI × condition interaction F(13,65) = 0.500, p=0.932; p-values obtained using permutation test; see Methods). Decoding was performed using data averaged over a time window 4.8–9.6 s into the trial, see Methods, Analysis: Disk orientation decoding for details. Error bars reflect ±1 SEM across participants, and light gray lines indicate individual participants. Dots above bars and pairs of bars indicate the statistical significance of decoding within each condition, and of condition differences, respectively, both evaluated using non-parametric statistics. Note that in this analysis, no significant condition differences were detected, and thus there are no dots above pairs of bars. Dot sizes reflect significance level.
