四个实验验证了一个新的假设，即非自愿的注意力转移取决于引发事件的性质和任务执行所需的性质之间的关系。在空间线索范式的变体中，系统地处理线索属性与目标定位有用属性之间的关系。在实验1中，无效的突发性提示对突发性特征的目标产生成本，而对颜色不连续特征的目标没有成本。在实验2中，无效的颜色提示对颜色目标产生的代价大于对突发目标产生的代价。实验3为这一模式提供了趋同证据。实验四考察了颜色不连续性引起注意转移的边界条件和时间过程。这些实验的结果表明，注意力捕获取决于由任务需求引起的注意力控制设置。
Four experiments tested a new hypothesis that involuntary attention shifts are contingent on the relationship between the properties of the eliciting event and the properties required for task performance. In a variant of the spatial cuing paradigm, the relation between cue property and the property useful in locating the target was systematically manipulated. In Experiment 1, invalid abrupt-onset precues produced costs for targets characterized by an abrupt onset but not for targets characterized by a discontinuity in color. In Experiment 2, invalid color precues produced greater costs for color targets than for abrupt-onset targets. Experiment 3 provided converging evidence for this pattern. Experiment 4 investigated the boundary conditions and time course for attention shifts elicited by color discontinuities. The results of these experiments suggest that attention capture is contingent on attentional control settings induced by task demands.
