生理周期与个体攻击性对女性识别愤怒-恐惧情绪的影响

Influence of female menstrual cycle and individual aggression on perception of angry to fear expression

目的探讨生理周期与个体攻击性对女性识别愤怒-恐惧表情的反应偏向和反应敏感性的影响,以揭示经前期女性负性情绪高发的心理机制。方法15名经前期女性与16名经后期女性作为研究对象,采用Buss-Perry攻击性问卷(Buss-Perry aggression questionnaire,BPAQ)进行攻击性测量。运用Logistic函数公式比较经前期与经后期女性情绪表情加工的反应偏向与敏感性差异;以经后期女性为对照组,进一步将经前期女性分为攻击性较高组与攻击性较低组,考察个体攻击性对经前期女性愤怒-恐惧表情识别加工的反应偏向与敏感性影响。结果经前期与经后期女性对愤怒-恐惧表情识别曲线的类别转折点差异无统计学意义(P>0.05),转折点处斜率差异有统计学意义(P<0.05);经前期低攻击组与高攻击组女性表情识别曲线的类别转折点差异有统计学意义(P<0.05),转折点处斜率差异无统计学意义(P>0.05);经后期高攻击组与低攻击组表情识别曲线的转折点差异无统计学意义(P>0.05),转折点处斜率差异有统计学意义(P<0.05)。结论经前期女性对愤怒-恐惧情绪的转变具有更高的敏感性,经前期低攻击性女性具有恐惧反应偏向,经后期高攻击性女性对愤怒-恐惧情绪转变更敏感。

Objective The present research examines the psychological mechanisms that lie behind the surge of negative emotion in female luteal phrase.To explore the effects of female menstrual phrases and individual aggression on the response bias and perceptual sensitivity in identifying angry to fear faces.Methods In the current study,15 females in luteal phrase and 16 females in the menses and follicular phrases participated in the experiment,the individual aggression level was measured by Buss-Perry aggression questionnaire(BPAQ).The response bias and perceptual sensitivity of two groups’emotional expression perception were compared by using the logistic formula to analyze the data.Taking menses and follicular women as the control group,the luteal phrase women were further divided into high-level aggression group and low-aggression group,and the influence of individual aggression on the response bias and perceptual sensitivity in identifying angry to fear faces of the luteal phrase women was investigated.Results There was a significant difference in the slopes of the emotional perception curves between luteal phrase females and follicular phrase females.The turning points between low-level aggression and high-level aggression luteal females were significantly different;the difference of slopes between low-level aggression and high-level aggression follicular females was notable.Conclusions Taken together,female in luteal phrase has higher sensitivity for the shift in anger to fear faces than female in menses and follicular phrases and females in luteal phrase with low-level aggression tend to exhibit a bias to perceive ambiguous expressions as fear while females in the menses and follicular phrases with high-level aggression are more perceptually sensitive to the change of facial anger to fear.
