MEG responses to sequences of varying alphabet size (experiment 4). (A) Group RMS of brain responses to REG5, REG10, and REG15 conditions, along with RAND20. Plotted is the entire stimulus epoch, from stimulus onset (t = 0) to offset (t = 3,500 ms). Intervals where a repeated measures bootstrap procedure indicated significant differences between each REG condition and RAND20 are marked with a line, underneath the brain responses. (B) Responses to REG5, REG10, and REG15 (identical to A) with those to their respective random controls (RAND5, RAND10, RAND15), and RAND20. Gray shading indicates temporal intervals where a significant difference (repeated measures bootstrap analysis; Materials and Methods) was found between responses to RAND5/10/15, respectively, and RAND20. (C) (Left) Responses to the different RAND stimuli (identical to B). (Right) Average RMS amplitude over the entire stimulus duration. Error bars indicate 1 SEM. (D) Model output showing trial-averaged information content for each tone pip from sequence onset for REG5, REG10, and REG15. Shading indicates 2 SEM.
