复杂决策任务的绩效可能取决于多个流程。爱荷华州赌博任务（IGT）和气球模拟风险任务（BART）这两项任务特别令人感兴趣，因为它们与现实世界的风险行为（包括非法吸毒）相关。我们使用认知模型来理清这两项任务中的底层流程。尽管 IGT 和 BART 的行为测量不相关，但认知模型揭示了两种可靠的跨任务关联。结果表明，这些任务类似地衡量损失厌恶和决策一致性过程，但不一定是相同的学习过程。此外，物质使用者（尤其是兴奋剂使用者）的 IGT 表现比健康对照者更差，这种模式可以通过决策一致性降低来解释。版权所有 (C) 2009 John Wiley & Sons, Ltd.
Performance on complex decision-making tasks may depend on a multitude of processes. Two such tasks, the Iowa Gambling Task (IGT) and Balloon Analog Risk Task (BART), are of particular interest because they are associated with real world risky behavior, including illegal drug use. We used cognitive models to disentangle underlying processes in both tasks. Whereas behavioral measures front the IGT and BART were uncorrelated, cognitive models revealed two reliable cross-task associations. Results suggest that the tasks similarly measure loss aversion and decision-consistency processes, but not necessarily the same learning process. Additionally, substance-using individuals (and especially stimulant users) performed worse oil the IGT than healthy controls did, and this pattern could be explained by reduced decision consistency.
