ABSTRACT

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 facespositive 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 random-ly),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 neg-ative emotional faces in cool colors ((636. 57±146. 20) ms) was significantly lower than that in positive e-motions ((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 af-fecting individual attention bias. Subjects showed attention bias ( especially negative information) on emo-tional face.
