不同情绪效价下风险决策中的性别差异
|
Abstract:
目的：探讨性别和情绪效价对个体风险决策的影响。方法：让60名被诱发相应情绪的大学生被试完成爱荷华博弈任务(Iowa Gambling Task，简称IGT)，采用2 (性别) × 2 (情绪效价)混合实验设计。结果：1)情绪效价主效应不显著(F = 0.01, P > 0.05)；性别主效应显著(F = 9.16, P < 0.05, ![\"\"](\"Edit_0058e222-da29-4d97-8bb7-714b63a51918.png\")
= 0.14)。2) 性别与情绪的交互作用显著(F = 37.34, P < 0.05, ![\"\"](\"Edit_0e6d81d1-df8c-41de-a279-7e6c3d466d50.png\")
= 0.39)，男性被试在积极情绪下的风险决策净得分显著小于消极情绪下的净得分(F = 18.30, P < 0.05,![\"\"](\"Edit_8439c486-a444-46c4-8d92-f8b0e7ed4998.png\")
= 0.39)，女性被试在积极情绪下的风险决策净得分显著大于消极情绪下的净得分(F = 19.42, P < 0.05, ![\"\"](\"Edit_ae299973-4a0f-4c55-82dc-6b72cd76475c.png\")
= 0.40)。结论：男性在正性情绪下偏好风险、负性情绪下规避风险；女性在正性情绪下规避风险，负性情绪下偏好风险。
Objective: To explore the effects of gender and affective valence on individual risk decision-making. Methods: 60 college students induced corresponding affection were asked to complete the Iowa gaming task (IGT). And 2 (gender) × 2 (affective valence) mixed experimental design was adopted. Results: (1) The main effect of affective valence was not significant (F = 0.01, P > 0.05); the main effect of gender was significant (F = 9.16, P < 0.05, ![\"\"](\"Edit_a3c90c0e-c58e-4d4d-8f1b-e6f099aeae21.png\")
= 0.14). (2) The interaction between gender and affective valence was significant (F = 37.34, P < 0.05), ![\"\"](\"Edit_70c561e8-e332-43fd-96e6-5e73962dcbfb.png\")
= 0.39), and the effect of affective valence on male (F = 18.30, P < 0.05, ![\"\"](\"Edit_528dfe0c-5d6d-4a54-b686-4e87725b026d.png\")
= 0.39) and female (F = 19.42, P < 0.05, ![\"\"](\"Edit_d9a01373-060d-4f1f-ae69-036761eda4e0.png\")
= 0.40). Conclusion: When confronting risk decision-making, men prefer risk under positive affection and avoid risk under negative affection but women avoid risk under positive affection and prefer risk under negative affection.
