Our study was a randomized controlled intervention trial. Subjects were randomized in one of two groups: the experimental group (TV, n = 37) watched a minimum of 8 h of visual media like television per day. The control group (NOTV, n = 37) did not consume any visual media. Both groups were accommodated in a controlled environment for 5 days and meanwhile completed a course in touch-typing on the PC keyboard. Touch-typing performance served as motor learning surrogate, as this skill was new to all participants. Before and after the experiment we conducted assessments (pre & post) on resting-state functional connectivity (fMRI), grey matter volume (VBM), visual attention (TVA), and somatosensory perception (MDT & GOT).
