Cognitive spatial processing and the regulation of posture.
Subjects performed the Brooks (1967) spatial and nonspatial memory tasks either while sitting or while maintaining a difficult standing balance position. The balance task disrupted spatial but not nonspatial memory performance. Balance steadiness during spatial and nonspatial memory conditions did not differ. These results suggest that cognitive spatial processing may rely on neural mechanisms that are also required for the regulation of posture.
