Abstract

Probability discounting, a subset of behavioral economic research, has a rich history of investigating choice behavior, especially as it pertains to risky decision making. Gambling involves both choice behavior and risky decision making which makes it an ideal behavior to investigate with discounting tasks. With proximity to a casino being one of the biggest risk factors, studies into the American Indian population have been a neglected population of study. Using outcome measures from a pre-scan probability discounting task, the current study equated the scan task to evaluate behavioral and neurobiological differences in gamblers vs. non-gamblers. Gamblers showed differences in behavioral tasks (lower discounting rates) but not in patterns of neural activation.

摘要

概率折扣作为行为经济学研究的一个子集，在研究选择行为方面有着悠久的历史，尤其是在涉及风险决策时。赌博既涉及选择行为又涉及风险决策，这使其成为用折扣任务进行研究的理想行为。由于靠近赌场是最大的风险因素之一，对美国印第安人群体的研究一直是被忽视的研究对象。本研究使用扫描前概率折扣任务的结果指标，将扫描任务等同起来，以评估赌徒与非赌徒在行为和神经生物学上的差异。赌徒在行为任务上表现出差异（较低的折扣率），但在神经激活模式上没有差异。
