Fig. 3: Experimental design and results for the behavioral tasks of the HDTBR experiment.

a We measured the BM and face inversion effects, which were respectively related to both motion and form processing and form processing alone. b Procedures of the BM and face perception tasks in which participants indicated whether two successively presented walkers/faces were the same. c The change of the perceptual inversion effect along five test sessions before (day −1), during (day 13, 27, & 43), and after the bed rest (day + 10) for the BM (blue line, n = 12) and the face (green line, n = 15) perception tasks. Error bars indicate ±1 SEM. Source data are provided as a Source Data file.
