RESUMO
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 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.
