Figure 2

Time-course of decoding accuracies of the cued and uncued orientations. (A) shows the decoding accuracy of the stimulus orientation over time, when the orientation was either presented in the cued colour (blue) or uncued (light green). The stimulus onset is marked with a vertical black line at 0 ms. Theoretical chance is 50% decoding accuracy, and shaded areas around the plot lines show the bootstrapped 95% confidence interval across participants (N = 20). Bayes factors are given below the plot on a log scale. Bayes factors below 1/10 are shown in grey, indicating strong evidence for the null hypothesis. Bayes factors above 10 are shown in the plot colour (blue for cued and light green for uncued), indicating strong evidence for the alternative hypothesis. Bayes factors between 1/10 and 10 are shown in white. The cued orientation could be decoded from 84 ms after the onset of the stimulus, and the uncued orientation from 80 ms after stimulus onset. (B) shows the effect of attention, measured as the difference in orientation decoding between the cued and uncued orientation (cued − uncued). The Bayes factors are given below the plot on a log scale. An effect of attention was present from 232 ms after stimulus onset.
