Fig. 4: Multivariate spectral decoding results.

Plotting of classifier accuracy against chance across the 2–30 Hz spectrum and all timepoints separately for low-intensity and high-intensity. Significant clusters (p < 0.05, corrected for multiple comparisons) are delimited by a solid black line. Dashed lines represent the minimum and maximum limits of significant clusters. The Area Under the Curve (AUC) within those limits in then averaged to depict the time course of classifier accuracy for low- and high-intensity (right column). Thicker lines represent statistical significance at p < 0.05. A Classifier accuracy for stimulus congruency. Information about congruency, and therefore the conflict effect, was only present at low-intensity in the 2–6 Hz band. B Time course of congruency decoding in the 2–6 Hz band in low- and high-intensity. C Classifier accuracy for stimulus spatial location. Information about location was only present at low-intensity in the 2–10 Hz band. D Time course of spatial location decoding in the 2–6 Hz band in low- and high-intensity. Narrowing the cluster permutation analysis show that information about stimulus location is still preserved to some extent at high-intensity. E Classifier accuracy for stimulus content. Information about location was present in both conditions throughout the frequency spectrum. F Time course of content decoding throughout the whole spectrum (2–30 Hz) in low- and high-intensity.
