Abstract

Errors in pointing to remembered target locations in 3-D space were studied when subjects were free to move the their heads to the extreme right or left. Relative to pointing when the head was free to move, head rotations to the right shifted the final position of the arm to the right. Horizontal rotation of the head had no systematic influence of head rotations on pointing errors may be mediated by small shifts in the internal representation of external space, shifting the presentation of space in the opposite direction of the head rotation.
