Fig. 4: Attention strength fluctuations correlate with performance.
From: Rhythmic sampling of multiple decision alternatives in the human brain
a The distribution of the overall attention strength difference, i.e., vector length, between correct and error trials (condition matched, see Methods). The blue line and shaded area indicate the average over participants (nparticipant = 20) and the standard error of the mean (SEM). Vertical dashed lines denote the stimulus onset (stim. on), framing cue onset and offset as well as the stimulus offset (stim. off, from left to right). b, c Time-frequency resolved (TFR) attention strength fluctuation differences between correct and error trials as a percent change to correct. b The distribution of TFR amplitude differences (Ampl. diff., correct-error) over the full spectrum and trial duration. The values were statistically masked at pFDR < 0.05 over the spectrum. c Frequency-wise amplitude change (as in b) averaged over the stimulus presentation period (− 1 to 2.8 s). Thick and thin lines display the average and single participant amplitude changes, respectively.
