From Capture to Control: Initial Capture Increases Learned Suppression
通过三项眼动追踪实验(120名大学生),发现初始分心事件能增强后续对显著刺激的抑制,若消除初始分心则抑制减弱,表明注意力捕获可作为学习信号改善未来控制。
Salient stimuli have the potential to distract us from our immediate goals. Much research has therefore aimed to understand how we learn to use attention to resist distraction by salient stimuli. We propose a new hypothesis whereby an initial instance of distraction can improve future suppression of salient stimuli. Across three experiments ( N = 120 college students, aged 18–35 years), we provide evidence for this hypothesis using a new eye-tracking approach. The results demonstrated that an initial instance of distraction occurred before salient distractors were suppressed. Notably, if this initial instance of distraction was eliminated or weakened via experimental manipulations, learned suppression of the distracting stimuli was greatly reduced. Together, these findings suggest that attentional capture can serve as a learning signal that improves future attentional control. They also indicate that learned suppression emerges rapidly, which has strong implications for models of attention and cognitive control.
