Risk taking behavior can be both adaptive and maladaptive depending on context. The majority of studies of risk taking, however, focus on clinical populations and dangerous or harmful risk taking. Individual differences in learning during risk taking are rarely examined in relation to task performance. The present study examined risk taking and associated outcomes in an exploration-based instrumental learning task (Balloon Emotional Learning Task; BELT), which presented a series of balloons in which participants pump up for points. Consistent with prior work, sensation seeking predicted increased risk taking behavior. Importantly, however, a significant interaction between sensation seeking and associative sensitivity, an attentional construct defined as the frequency and remoteness of automatic cognitive activity, was found. Specifically, among individuals high in sensation seeking, associative sensitivity predicted fewer balloon explosions and an increase in points earned on the balloon condition with the most potential feedback driven learning. Thus, these findings suggest that sensation seekers are a heterogeneous group, and secondary traits such as associative sensitivity moderate behavior such as risk taking and learning according to context.
冒险行为根据具体情境既可能具有适应性,也可能具有适应不良性。然而,大多数关于冒险行为的研究都集中在临床人群以及危险或有害的冒险行为上。在冒险过程中,很少有人研究学习方面的个体差异与任务表现之间的关系。本研究在一项基于探索的工具性学习任务(气球情绪学习任务;BELT)中考察了冒险行为及相关结果,该任务呈现一系列气球,参与者为了得分给气球充气。与先前的研究一致,感觉寻求预测了冒险行为的增加。然而,重要的是,发现了感觉寻求与联想敏感性之间的显著交互作用,联想敏感性是一种注意力结构,定义为自动认知活动的频率和远距性。具体而言,在感觉寻求程度高的个体中,联想敏感性预测了更少的气球爆炸次数,以及在具有最大潜在反馈驱动学习的气球条件下得分的增加。因此,这些发现表明,感觉寻求者是一个异质性群体,诸如联想敏感性等次要特质会根据情境调节冒险和学习等行为。
