Résumé
Two experiments are reported that test whether the modulation of exogenouscuing effects by the presence of a distractor at the location opposite thetarget (altering the time course of cueing effects, Lupiáñez et al., 1999,2001) is due to the fast reorienting of attention or to a set for preventing theintegration of the cue and the target within a single event representation. ASpatial Stroop task was used to explore whether the long lasting facilitationeffect usually found in this task, as well as the typical reduction of SpatialStroop interference on cued trials (Funes et al., 2003, 2005) is prevented bythe presence of distractors. In Experiment 1, the distractor produced a shifttowards more negative cuing effects even at the shortest 100 ms SOA, andeliminated the Spatial Stroop by Cueing interaction. In Experiment 2, alarger range of SOAs was introduced, demonstrating further that thenegative shift of cueing effects found in Experiment 1 affected all levels ofSOA equally. This pattern of results is explained in terms of the eventsegregation hypothesis.
