The present paper shows that the exogenous spatial cueing effect moves along with a rotating object. We exogenously cued one side of a horizontal bar with an abrupt onset.After cueing, this bar rotated to a vertical position. We found an object-centered cueing effect. In a second experiment, we cued one arm of a rotating cross and showed that retinotopic(eye-centered) and object-centered cueing effects are equally strong. Our results indicate that retinotopic and object centered reference frames are simultaneously present and accessible. Consistent with neurophysiology, we argue that there are two dissociable attentional systems: one for visual object processing and one for spatial processing [corrected].
