Manual pointing to auditory targets: performances of right versus left handed subjects.
In order to test the existence of an hemispheric asymmetry at a basic level of spatial information processing, six right handed and six left handed normal subjects were submitted to a manual pointing task to auditory targets. Results showed a shift in perceived target position according to the hand used for pointing, a striking asymmetry between the two auditory hemispaces reflected in both groups in directional error and dispersion.
