情绪对变化盲视的影响

目的:探讨情绪对变化盲视现象的影响。方法:采用3(情绪:积极/中性/消极)×3(刺激类型:出现消失类/颜色改变类/完全替换类)的混合设计,以"图片+故事"作为情绪诱发材料,选取76名被试完成经典闪烁范式的变化探测任务。结果:①情绪主效应边缘显著,F=2.96,P=0.059;②刺激类型主效应显著,F=22.00,P<0.001;③刺激类型和情绪的交互作用显著,F=6.759,P<0.001。结论:①积极情绪促进个体对变化的觉察,消极情绪阻碍个体对变化的觉察;②情绪对变化盲视的影响受到任务难度的调节。在任务难度较大时,积极情绪促进变化觉察,消极情绪阻碍变化觉察,任务难度较小时,积极情绪和消极情绪对变化觉察的影响没有显著差异。

The Influence of Emotion on Change Blindness

Objective: To explore the influence of emotion on change blindness.Methods: This research adopted a 3(emotion: positive/neutral/negative) ×3(stimulus type: appear-disappear/colour change/substitution) mixed design."Picture & Story" materials were used to induce three different emotions ——positive,neutral and negative,and 76 subjects were asked to perform change detection tasks in flicker paradigm.Results: ①The main effect of emotion is marginally significant(F=2.96,P=0.059);②There were significant differences among the tree types of change(F=22.00,P<0.001);③The interaction of emotion and change type was significant as well(F=6.759,P<0.001).Conclusion: ①Positive emotion facilitates one’s change detection,while negative emotion hinders this cognitive process;②There is a significant interaction between emotion types and change types.That is,the influence of emotion on change blindness is mediated by task difficulty—positive emotion facilitates change detection in difficult tasks,while emotion states have no significantly different effect on change detection in easy tasks.
