  1. VI-1: visual motor imagery in the first-person perspective; VI-3: visual motor imagery in the third-person perspective; KI: kinesthetic motor imagery; MI: motor imagery; ME: motor execution.
  2. *P < 0.05.
  3. †The items for easiness and consistency of MIs were rated on a 10-point scale from 0 to 10, and other items were rated on a 5-point scale from 1 to 5.
