Data are P values for all tests reported in Fig. 5. To assess whether each region of interest (ROI) was sensitive to visual salience and behavioral relevance (and their interaction), we performed a 2-way, repeated-measures ANOVA with factors of visual salience (20%, 40%, 80% contrast) and behavioral relevance (attended or unattended). To generate P values, we compared the F score derived for each main effect and their interaction with those derived from a shuffling procedure in which we shuffled the data labels within each participant independently 1,000 times. Because we ran 1,000 iterations of this shuffling procedure, the minimum accurate quantifiable P value was 0.001. Bold P values indicate significant effects after correction for multiple comparisons (false discovery rate, q = 0.05 across all comparisons, threshold P ≤ 0.011). P values in italics indicate trends, defined as P ≤ 0.05 with no correction for multiple comparisons. Int, interactions.
