Sensory and motor aspects of pseudoneglect, hemifield, and hemispace in the tactile modality

Brain Cogn. 1991 May;16(1):74-82. doi: 10.1016/0278-2626(91)90086-n.

Abstract

Two experiments were conducted with right-handed adult subjects to investigate motor and sensory components of a tactual line bisection task performed under three conditions: at midline, in the left, and in the right hemispaces. In the sensory experiment we found a left-hand rather than a right-hand superiority under the midline condition and, in the motor experiment, a right-hand rather than a left-hand superiority. The results were discussed with respect to hemispheric specialization and hemispace theories. Furthermore, we found a pseudoneglect (subjects bisected to the left of the midpoint) in the sensory experiment and a surprising reversed pseudoneglect (subjects bisected to the right of the midpoint) in the motor experiment.
