In the sense of ideomotor theories, actions are controlled by the anticipation of their environment- and body-related effects. For some actions (e.g., when using a tool with a lever), these effects are incompatible, e.g., in the spatial domain. Recent evidence suggests that the interference posed by spatially incompatible action effects can be overcome by downregulating body-related effect codes, as reflected by reduced tactile sensitivity in the effector shortly before action initiation. This study posed a critical test of the haptic-neglect hypothesis by maximizing participants' need to downregulate body-related effect codes. Participants moved a digital tool (i.e., a cursor) from the center of a circle to one of 8 potential directions by moving their finger on a textured surface in either the exact same direction (compatible) or in the exact opposite direction (incompatible). Shortly before (~100ms) or after movement initiation (~100ms), they received tactile stimulation of different intensities on their active hand in 89% of the trials. Before movement onset, we observed reduced tactile sensitivity in the effector, as reflected by lower d' and higher detection thresholds in incompatible compared to compatible movements.
