Color decoding peaked later for upcoming parafoveal compared with foveal images. The peak latency differences between foveal and upcoming parafoveal images computed during the foveation for the n = 36 participants. A, Color classification. The peak latency difference was significantly above 0 (two-tailed paired t test: t(35) = 5.12, p < 0.001, Cohen's d = 1.21, CI95% = [0.03, 0.07], BF10 > 100). The peak of classification for parafoveal images was ∼45 ms later than for foveal images. B, Category classification. The peak latency difference was not significantly different from 0 (two-tailed paired t test: t(35) = 1.33, p = 0.19, Cohen's d = 0.31, CI95% = [−0, 0.01], BF10 = 0.4). There was no strong evidence in favor or against the null hypothesis. The horizontal bar in the violin plots indicates the mean value. Filled circle, participant's difference. Empty circle, average difference across n = 36 participants.
