초록/요약
Numerous studies found the evidence of the memory-based attentional capture effect: A representation in visual working memory can guide visual attention toward the location of the object sharing the representation (Downing, 2000; Olivers et al., 2006; Soto et al., 2005). However, other studies failed to find the evidence for the memory-based attention. This discrepancy might be due to the limited experimental paradigm: the visual search paradigm. To eliminate the possibility that participants voluntarily attend to the memory-matching cue, the pre-cuing paradigm of Folk (1992) and the memory task of Olivers (2006) were used in the present study. In Experiment 1, it was tested whether the memory-based capture effects occur on the basis of the categorical tuning filter in the pre-cuing paradigm, as in Folk (1992). Either a color or shape cue appeared. Experiment 2 examined whether the memory-based attentional capture effects could operate with the feature specific tuning filter in the domain of color, as in Folk (1998), and whether the effect is due to visual working memory or verbal working memory, as in Olivers (2006). Experiment 3 to 5 tested whether the effects in Experiment 2 would be obtained in the domain of shape. The present study shows that color and shape representations in visual working memory can automatically capture visual attention.
