背景颜色对大学生不同情绪面孔注意偏向的影响

The influence of background color on the attentional bias from different emotional faces of college students

目的考察背景颜色对大学生不同情绪面孔的注意偏向。方法本研究采用2(背景颜色:冷色调、暖色调)×2(情绪面孔:积极、消极)的被试内试验设计,基于情绪面孔点探测范式,记录26名大学生的正确判断反应时。结果(1)相较于积极面孔[(677.31±138.66)ms],大学生对消极面孔反应时更短[(637.97±121.69)ms],差异有统计学意义(P<0.05)。(2)背景颜色与情绪面孔的交互作用显著(F=4.92,P<0.05)。冷色调背景下消极情绪面孔的反应时[(636.57±146.20)ms]显著低于积极情绪面孔[(721.23±180.40)ms,P<0.05]。暖色调背景下消极情绪面孔与积极情绪面孔反应时差异无统计学意义(P>0.05)。结论冷色调背景颜色会激发大学生较多的消极情绪,从而影响个体的注意偏向。

Objective To examine the attention bias of background color from different emotional faces. Methods The study adopt 2 (background colors: cool and warm)× 2 (emotional faces: positive and negative emotions) within experimental design to examine the subjects' attention from different background color by 26 participants of college students (26 participants were selected to conduct experiments randomly), with the background color and emotional face as independent variables. Results (1) Compared with positive face, the response time of negative face was shorter((677.31±138.66)ms vs (637.97± 121.69)ms), indicating that the attention bias of different emotional faces was significantly different(P<0.05).(2) The interaction between the background color and the emotional face is significant. The response time of negative emotional faces in cool colors ((636.57±146.20) ms) was significantly lower than that in positive emotions ((721.23±180.40) ms, P<0.05). There was no significant difference in warm colors (P>0.05). Conclusion The cool background color can stimulate more negative emotions of college students, thus affecting individual attention bias. Subjects showed attention bias (especially negative information) on emotional face.
