Object-centered orienting and IOR.

Three recent studies reported retinotopic (eye-centered) and object-centered attentional facilitation following exogenous cuing in dynamic displays. The present study replicates this finding and shows, under the very same experimental conditions, inhibition of return (IOR) in both retinotopic and object-centered reference frames. Unlike in previous findings, we show that when a single object is present in the display, IOR is bound to both retinotopic and object-centered locations, defined as a specific location within the boundaries of a single object.
