| Research Abstract |
We tested effects of reaching movements on spatial attention. Subjects could make rapid mid-flight adjustments when reaching for a target that jumped to either a left or right side unexpectedly. However, corrections were quicker and more accurate when the target jumped toward the contralateral hemispace relative to used arm than the ipsilateral hemispace. This attentional asymmetry was also obtained under a virtual environment where motor and visual space were dissociated, but only when subjects could use information about their arm movements. Moreover, the asymmetry was obtained even when subjects observed reaching movements performed by other individuals.
