No significant differences were found between the 5- and 8-year-olds for any of the following measures: A) the temporal signal to noise ratio (tSNR) in any region of interest (all t’s < 0.64, all p’s > 0.52); B) participant head motion (average absolute frame-to-frame displacement for all usable runs) (t(30) = 0.75, p = 0.46), or C) V1 activation (i.e., the average response in V1 across all conditions minus fixation; t(30) = 0.90, p = 0.38). Error bars depict the standard error of the mean.
