Figure 2.

The figure presents one session, including three runs. Each run consists of a standing condition and a sitting condition. In the standing condition, participants were either exposed to a stable or a dynamic fixation condition. The stable fixation condition and the sitting conditions were not analyzed in the present study. The standing condition consisted of seven task blocks and the sitting condition of three task blocks. After completing one run with visual-manual and auditory-vocal response mappings, another run with visual-vocal and auditory-manual response mappings was conducted. The order of runs was pseudorandomized across participants. P: postural task; C: cognitive task; CP: cognitive-postural task; CCP: cognitive-cognitive postural task.
