Rapid development of spatiotopic representations as revealed by inhibition of return Academic Article uri icon

abstract

  • Inhibition of return (IOR), a performance decrement for stimuli appearing at recently cued locations, occurs when the target and cue share the same screen-position (ie spatiotopic mapping; Posner and Cohen, 1984; Maylor and Hockey, 1985). This is in contrast to cue- based attention-facilitation effects that were recently suggested to be mapped in a retinotopic reference frame (Golomb et al., 2008), the prevailing representation throughout early visual processing stages. Here, we investigate the dynamics of IOR formation in both reference frames, using a modified cued-location reaction-time task with an intervening saccade between cue and target presentation. This enabled creating trials in which the target was present at the same retinotopic location as the cue, and trials with the same screen-position (spatiotopic trials). IOR was primarily found for targets appearing at the …
