Impact of head motion on orientation decodability. (A) The correlation between a head motion index—reflecting the average translation and rotation changes per volume/2 s—and average orientation classification performance (averaged across all stimulus types) across participants. There are 17 data points because we excluded one participant whose average head motion was more than three standard deviations greater than the group average. (B) Pearson correlation coefficients and (C) p-values for the correlation between head motion and decoding performance based on activity patterns that were band-pass filtered at spatial frequencies ranging from 1 to 40 mm.
