The link between Attention-Deficit/Hyperactivity Disorder (ADHD) and steeper delay discounting has been established and incorporated into theories of ADHD. This study examines a novel interpretation according to which ADHD is linked to sub-optimal temporal decision-making and suggests inconsistency as a potential underlying mechanism. In two experiments, MTurk workers completed a self-report questionnaire on symptoms of ADHD and a temporal decision making task consisting of choices between smaller-immediate and larger-delayed options. The delayed option was better in some items, whereas the immediate option was better in others. The rate of choices of the delayed option and the consistency of choices were measured. The results of both studies show that high symptoms of ADHD were linked to fewer choices of the delayed option when it was better, but also to more choices of the delayed option when it was not better. In addition, ADHD was linked to higher inconsistency in both conditions. The findings suggest that ADHD is linked to sub-optimal temporal decision-making rather than steeper delay discounting, and provide further support to the phenomenon of inconsistency in ADHD.
注意力缺陷多动障碍（ADHD）与更陡峭的延迟折扣之间的联系已经确立，并被纳入ADHD的理论之中。本研究考察了一种新的解释，即ADHD与次优的时间决策有关，并提出不一致性是一种潜在的潜在机制。在两项实验中，MTurk工作人员完成了一份关于ADHD症状的自我报告问卷，以及一项时间决策任务，该任务包括在较小的即时选项和较大的延迟选项之间进行选择。在某些项目中，延迟选项更好，而在其他项目中，即时选项更好。测量了延迟选项的选择率和选择的一致性。两项研究的结果都表明，ADHD的高症状与延迟选项更好时较少选择该选项有关，但也与延迟选项不好时更多选择该选项有关。此外，在两种情况下，ADHD都与更高的不一致性有关。研究结果表明，ADHD与次优的时间决策有关，而不是与更陡峭的延迟折扣有关，并为ADHD中的不一致现象提供了进一步的支持。
