经典的空间注意理论假设空间注意有两种模式，即自主注意和非自主注意。Folk、Remington和约翰斯顿（1992）指出，即使是由刺激引起的无意识注意捕获，也需要刺激属性与观察者正在寻找的内容相匹配。这一惊人的结论得到了后续多项研究的证实。然而，在这些研究中，观察者通常在整个会话中寻找相同的属性。相比之下，现实世界的行为往往需要注意力的频繁转移。本研究探讨了这种转移是否会削弱注意力设置，使任务无关的对象，以捕捉注意。令人惊讶的是，波动的控制设置并没有增加脆弱性捕获的显着刺激（颜色单例和突然发病）。我们的结论是，注意力控制系统是非常灵活的，能够迅速和充分地采用新的设置和放弃旧的设置。
The classic theory of spatial attention hypothesized 2 modes, voluntary and involuntary. Folk, Remington, and Johnston (1992) reported that even involuntary attention capture by stimuli requires a match between stimulus properties and what the observer is looking for. This surprising conclusion has been confirmed by many subsequent studies. In these studies, however, the observer typically looks for the same property throughout an entire session. Real-world behavior, in contrast, often requires frequent shifts in attentional set. The present study examined whether such shifts weaken attentional settings, allowing task-irrelevant objects to capture attention. Surprisingly, fluctuating control settings did not increase vulnerability to capture by salient stimuli (color singletons and abrupt onsets). We conclude that the attention control system is remarkably flexible, able to rapidly and fully adopt new settings and abandon old settings.
