Slopes were estimated with linear mixed effects analysis. Each row shows a particular data set (previously published, studies 1, 2, and 3, and all available data). Sustained Posterior Negativity (SPN) and Global Field Power (GFP) amplitudes were averaged 300–1000 ms window. Min and max W columns show the range of W values for stimuli included in the analysis.
