Mixed ANOVAs comparing the RHI for left and right hand use conditions for (A) left-handers and (D). right-handers. Follow-up linear contrasts analyses then looked for significant linear effects of drift across the four hand positions, again for (B) the left (dominant) hand used and (C) right (non-dominant) hand used conditions for left-handers, then for (E). The left (non-dominant) and (F) right (dominant) hand used conditions for right-handers. For both groups, a significant linear effect of drift was found for the dominant, but not non-dominant hands. p < 0.05 are represented with an asterisk (*)
