目的 探讨大学生在应激状态下面孔再认加工中不同情绪效价间的偏好性.方法 采用学习-再认范式,比较应激状态下的大学生对不同情绪效价的面孔再认反应时和正确率的差异.结果 应激状态下被试存在面孔再认反应时的主效应(F(2.59)=5.13,P=0.007)以及再认反应时和组别的交互作用(F(2.59)=6.02,P=0.003),面孔的再认正确率有主效应(F(2.59)=14.47,P=0.000),进一步分析发现,应激组对正性面孔的再认速度[(645.84± 52.65) ms]明显快于中性[(692.99±63.17) ms]和负性情绪面孔[(721.46± 101.76)ms] (P＜0.05),应激组对正性面孔的再认正确率(0.68±0.084)最高.结论 应激个体存在对正性面孔再认偏好.
目的 探討大學生在應激狀態下麵孔再認加工中不同情緒效價間的偏好性.方法 採用學習-再認範式,比較應激狀態下的大學生對不同情緒效價的麵孔再認反應時和正確率的差異.結果 應激狀態下被試存在麵孔再認反應時的主效應(F(2.59)=5.13,P=0.007)以及再認反應時和組彆的交互作用(F(2.59)=6.02,P=0.003),麵孔的再認正確率有主效應(F(2.59)=14.47,P=0.000),進一步分析髮現,應激組對正性麵孔的再認速度[(645.84± 52.65) ms]明顯快于中性[(692.99±63.17) ms]和負性情緒麵孔[(721.46± 101.76)ms] (P＜0.05),應激組對正性麵孔的再認正確率(0.68±0.084)最高.結論 應激箇體存在對正性麵孔再認偏好.

Objective To investigate whether there is emotional memory advantage bias to negativc emotion facial expressions in stress.Methods A "learning-recognition" paradigm was used in this study,and 2 groups (stress/non stress)× 3 facial emotional valence (positive/neutral/negative) mixed designs were adopted to compare the reaction time deviations to different facial emotion expressions in stress participants and relaxing participants.Results It was shown by repeated measurement ANOVA that the main effect(E(2.59)=5.13,P=0.007) in facial emotional response time and the interaction effect (F(2.59) =6.02,P=0.003)between groups and facial emotional expression were found.The main effect in recognition of accuracy was observed(F(2.59)=14.47,P=0.000).Further analysis showed,for stress participants,that the reaction time to detect stimulus of positive facial expression ((645.84± 52.65) ms) was faster than negative ((721.46± 101.76) ms) and neutral faces ((692.99 ± 63.17) ms) (P＜0.05) and the recognition of the latter expressions was not significant.Interestingly,the accuracy to recognized of positive facial expression (0.68 ± 0.08) was the highest (P ＜ 0.05) for stress participants.Conclusion Positive faces advantage to facial expression is shown at the stage of face recognition in stress group.
