Influence of emotional valences on risk decision of college students with early life stress / 中华行为医学与脑科学杂志

ABSTRACT

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 η2=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 η2=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 η2=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.
