Risks often accompany available choices in decision-making, particularly where the monetary factor gets involved. Researchers have explored the pathways underlying risky decision-making for decades, but most of these pathways have explored the factors individually rather than through a holistic approach. The present study examines the role of personality, cognitive, and biological components in risky decision-making. Here, the Iowa Gambling Task (IGT) paradigm is used to study the targeted outcome variable (IGT payoff) in 281 healthy students. Two moderation-mediation models hypothesized sensation seeking and lack of premeditation as predictors of IGT payoff. Positive and negative moods prior to IGT administration were considered mediators, and age and gender as moderators in predicting payoff. The hypothesized models were tested using conditional process analysis. Results indicate that both predictors significantly negatively predict payoff while moderated by gender and age categories. Interestingly, the indirect relationships apply to 21-34 years old men and 21-25 years old women. These age and gender-specific findings in apparently healthy participants highlight the need for replicating the current research in different age groups and clinical populations involving maladaptive decision-making patterns.
风险常常伴随着决策中的可选择方案,特别是在涉及货币因素的情况下。几十年来,研究人员一直在探索风险决策背后的途径,但这些途径大多是单独探索因素,而不是通过整体方法。本研究考察了人格、认知和生物成分在风险决策中的作用。在这里,爱荷华赌博任务(IGT)范式用于研究 281 名健康学生的目标结果变量(IGT 收益)。两个调节-中介模型假设感觉寻求和缺乏预谋是 IGT 收益的预测因子。IGT 管理之前的积极和消极情绪被认为是中介,年龄和性别是预测收益的调节因素。使用条件过程分析测试了假设模型。结果表明,两个预测因子都显著负向预测收益,同时受到性别和年龄类别的调节。有趣的是,间接关系适用于 21-34 岁的男性和 21-25 岁的女性。在明显健康的参与者中,这些年龄和性别特定的发现强调了在不同年龄组和涉及适应不良决策模式的临床人群中复制当前研究的必要性。
