Crossing the hands disrupts tactile spatial attention but not motor attention: Evidence from event-related potentials

► Attention and movement preparation tasks performed with crossed and uncrossed hands. ► In the Attention task, tactile attentional selection is disrupted with crossed hands. ► In the Motor task, enhanced tactile processing at the cued hand (motor attention). ► Crucially, hand posture does not affect motor attention. ► Motor and spatial attention weigh anatomical and external spatial codes differently.
