Summary of "On the time course of spatial cueing: Dissociating between a set for fast reorienting and a set for cue-target segregation."

The present study tests whether two different manipulations leading to an earlier appearance of Inhibition of Return might operate by setting the system in different ways. Whereas the use of a range of very long SOAs has been proposed to set the system for an early reorienting of attention (Cheal & Chastain, 2002), introducing a distractor at the location opposite the target seems to induce a set to represent the cue and the target as separated events instead of the same event (Lupiáñez et al., 1999, 2001). The effects of these two manipulations were directly compared by using a spatial stroop paradigm. Although both manipulations altered the time course of cueing effects, we report here a pattern of critical dissociations: (i) the distractor manipulation was unique in introducing a shift towards more negative cueing affecting generally all levels of SOA, including the shortest 100 ms SOA; and (ii) the distractor manipulation, but not the range of SOAs, was also able to prevent the expected interaction between spatial stroop effects and cueing effects at the shortest SOA, typically found in previous experiments in the absence of a distractor (Funes et al., 2003). This pattern of dissociations is well accommodated into the hypothesis that these two attentional sets are different in nature.
