情绪效价对早期生活应激大学生风险决策的影响

Influence of emotional valences on risk decision of college students with early life stress

目的探究情绪效价对早期生活应激和非早期生活应激大学生风险决策的影响。方法本研究采用儿童心理虐待与忽视量表在大学生群体中筛选出早期生活应激被试(早期生活应激组,n=30)和非早期生活应激被试(非早期生活应激组,n=30),比较两组在不同效价的情绪状态(积极、消极、中性)下爱荷华博弈任务中的决策表现。用SPSS 23.0软件对各条件下的两组被试决策表现进行了重复测量方差分析以及随后的Sidak或Dunnett T3事后检验。结果(1)早期生活应激的组别主效应显著[F(1,58)=4.35,P=0.04,偏η^2=0.07],早期生活应激组比非早期生活应激组更倾向于风险规避[(27.20±6.95)次,(23.53±9.18)次];(2)情绪效价的主效应显著[F(2,116)=3.45,P=0.04,偏η^2=0.06],两组被试在消极情绪下产生了比积极情绪下更强烈的风险偏好[(26.38±9.09)次,(23.88±7.58)次];(3)早期生活应激与情绪效价的交互作用显著[F(2,116)=0.72,P=0.49,偏η^2=0.01],情绪对早期生活应激组和非早期生活应激组的影响趋势和程度基本一致。结论早期生活应激和情绪效价均会对个体的风险决策产生影响,情绪效价对决策的影响并不会随着早期生活应激的有无而变化。

Objective:To explore the impact of emotional valences on the risk decision performance in college students with or without early life stress.Methods:The child psychological abuse and neglect scale was used to select 30 subjects with early life stress and 30 subjects without early life stress from college students.Iowa game task was conducted under different emotional valences(positive,negative,neutral).Data were analyzed by SPSS 23.0 in the manner of MANOVA of repeated measuring,and the posthoc tests were carried out by the way of Sidak or Dunnett T3.Results:(1)The main effect of early life stress was statistically significant(F(1,58)=4.35,P=0.04,partial η^2=0.07,which meant the early life stressors tended to be more risk-averse than the non-early life stressors((27.20±6.95)vs(23.53±9.18)).(2)The main effect of emotional valence was statistically significant(F(2,116)=3.45,P=0.04,partial η^2=0.06)),which meant all participants developed a greater risk preference in negative emotions than positive emotions((26.38±9.09)vs(23.88±7.58)).(3)The interaction between early life stress and emotional valence was not statistically significant(F(2,116)=0.72,P=0.49,partial η^2=0.01),and the influence trend and degree of emotion valence on early life stressors and non-early life stressors were basically same.Conclusion:Both emotion and early life stress have an impact on individual risk decision,but the effect of emotion with different emotional valence on risk decision-making performance of the early life stressors and the non-early life stressors has no significant difference.
