On the spread of spatial attention in touch: Evidence from event-related brain potentials.

To investigate the distribution of tactile spatial attention near the current attentional focus, participants were cued to attend to one of four body locations (hand or shoulder on the left or right side) to respond to infrequent tactile targets. In this Narrow attention task, effects of spatial attention on the ERPs elicited by tactile stimuli delivered to the hands were compared as a function of the distance from the attentional focus (Focus on the hand vs. Focus on the shoulder).
