突发性公共卫生事件对健康个体选择性注意的影响

The Impact of Public Health Emergencies on the Selective Attention of Healthy Individuals

目的:探究健康个体对公共卫生事件信息的选择性注意特点。方法:采用Flanker任务,通过两个实验分别考察被试(n1 = 30, n2 = 31)在常态和公共卫生事件突发状态下,对不同效价的相关信息的选择性注意特点。结果:① 在常态和突发状态下,被试对公共事件有关信息的反应都显著快于无关信息;② 突发状态下,被试对负性信息的反应显著慢于对正性信息的反应,且Flanker效应消失。结论:公共卫生事件信息具有特异性,能够获得更多注意资源,吸引个体的注意;突发状态下健康个体花费更长的时间加工负性刺激,其注意抑制加工增强。本研究揭示了突发性公共卫生事件对个体选择性注意的影响,有助于理解人们对特异性刺激的注意加工机制。

Objective: To explore the selective attention characteristics of healthy individuals towards public health emergency information. Methods: The Flanker task was employed to investigate the selec-tive attention characteristics of subjects (n1 = 30, n2 = 31) towards information of different valences during normal and public health emergency conditions through two experiments. Results: ① Un-der both normal and emergency conditions, subjects’ responses to relevant information regarding public events were significantly faster than to irrelevant information. ② During emergency condi-tions, subjects’ responses to negative information were significantly slower than to positive infor-mation, and the Flanker effect disappeared. Conclusion: Public health emergency information pos-sesses specificity, garnering more attention resources and capturing individuals' focus. Healthy in-dividuals, during emergency situations, take longer to process negative stimuli, with enhanced at-tention inhibition processing. This study reveals the impact of sudden public health emergencies on individual selective attention, contributing to the understanding of attention processing mecha-nisms for specific stimuli.
