呈现频率对情绪刺激注意捕获的影响

The Influence of Presentation Frequency on the Capture of Attention from Emotional Stimuli

摘要: 注意捕获是指某些刺激能够捕获注意或者让我们优先处理特定信息的感知过程，分为自上而下的注意捕获和自下而上的注意捕获。实验采用额外单例范式，操纵情绪刺激的呈现频率，考察情绪刺激的注意捕获是否受到目标导向过程的调节。实验要求被试搜索并判断特定方向的中性面孔的性别，而情绪面孔从来不会作为目标出现，这样做分离了情绪刺激的物理显著性和任务相关性。结果表明：无论情绪刺激呈现频率高低，都不会捕获注意。表明呈现频率不会影响情绪刺激的注意捕获，情绪刺激的注意捕获受到目标导向过程的调节。研究结果表明，情绪刺激的注意捕获不是自动化的，而是自上而下的。

Abstract: Attention capture refers to the perceptual process in which certain stimuli can capture attention or make us prioritize the processing of specific information. It is divided into top-down attention capture and bottom-up attention capture. The experiment adopted an additional singleton paradigm to manipulate the presentation frequency of emotional stimuli and examine whether the attention capture of emotional stimuli is regulated by the goal-oriented process. The experiment required the participants to search for and determine the gender of neutral faces in a specific direction, while emotional faces were never targeted. This approach separated the physical significance of emotional stimuli from their task relevance. The results show that regardless of the frequency of emotional stimulation, it will not capture attention. It indicates that the presentation frequency does not affect the attention capture of emotional stimuli, which is regulated by the goal-oriented process. The research results show that the capture of attention to emotional stimuli is not automated but top-down.
