Figure 4.

The four-way interaction between posture, responding hand, magnitude, and response key on mean RTs is depicted. Vertical bars denote 95% confidence intervals. (A,B) When participants kept their hands in a prone posture, the SNARC effect was significant for the right hand only (and likely driven by the difference between left and right key for large numbers). (C,D) When participants kept their hands in a supine posture, the SNARC effect was significant for the left hand only (and likely driven by the difference between left and right key for small numbers).
