We explored attentional capture about target-nontarget relation using spatial-cuing paradigm. In Experiment 1, we explored whether attentional capture was depended on whether a cue-cue context color relations match the target-nontarget relations or not. In Experiment 2, participants were asked to neglect specific color relation , only to differentiate odd colored target letter of the other color relation. Under such circumstance, the participants can establish relatively strong attentional control setting for purpose of expanding the possibility to focus on the color relations.The results reflected the difference in generalized top-down tuning, with target discrimination guided by a singleton search mode in Experiment 1, and tuned by a attentional control setting in Experiment 2. These demonstrated that it can capture attention only when cue-cue context relations match the target-nontarget relations , a cue with the target-nontarget match can fail to capture attention when the cue-cue context relations do not match the target-nontarget relations, whereas a cue with the nontarget color can capture attention when its relations match the target-nontarget relations. It was concluded that top-down modulation of attentional control setting have great influence on attentional capture. Only when strong attentional control setting established, attention capture depends on relations instead of particular feature values.
