Abstract

Objective: Little research has investigated decision making in patients with Korsakoff syndrome (KS). Specifically, to our knowledge, there is a lack of research investigating whether patients with KS may tend to prefer immediate over future rewards (i.e., temporal discounting). Further, we investigated the relationship between temporal discounting and inhibition.

Methods: We, for the first time, invited patients with KS and control participants to perform a temporal discounting task, in which they answered questions probing preferences between an immediate, but smaller amount of money, and a delayed, but larger amount of money (e.g., "would you prefer 10 dollars today or 50 dollars after one month?"). Furthermore, inhibition was measured using the Stroop Colour Word Test.

Results: Analysis demonstrated higher temporal discounting in patients with KS than in control participants. Temporal discounting in both populations was significantly correlated with inhibition.

Conclusions: Patients with KS may have difficulties to suppress the temptation of smaller, but immediate, rewards.

“今天10美元还是一个月后50美元?”Korsakoff综合征的时间折扣。

目的:研究Korsakoff综合征(KS)患者的决策问题。具体而言，据我们所知，缺乏关于KS患者是否倾向于选择即时奖励而非未来奖励(即时间折扣)的研究。进一步，我们研究了时间折扣和抑制之间的关系。方法:我们首次邀请患有KS的患者和对照组参与者执行一项时间折扣任务，在这项任务中，他们回答了一些问题，探讨了在立即得到但金额较小的钱和延迟得到但金额较大的钱之间的偏好(例如，“你喜欢今天得到10美元还是一个月后得到50美元?”)。此外，使用Stroop颜色单词测试来测量抑制作用。结果:分析表明，与对照组相比，KS患者的时间折扣更高。两个群体的时间折扣与抑制显著相关。结论:KS患者可能难以抑制较小但即时奖励的诱惑。

期刊介绍： Cognitive Neuropsychiatry (CNP) publishes high quality empirical and theoretical papers in the multi-disciplinary field of cognitive neuropsychiatry. Specifically the journal promotes the study of cognitive processes underlying psychological and behavioural abnormalities, including psychotic symptoms, with and without organic brain disease. Since 1996, CNP has published original papers, short reports, case studies and theoretical and empirical reviews in fields of clinical and cognitive neuropsychiatry, which have a bearing on the understanding of normal cognitive processes. Relevant research from cognitive neuroscience, cognitive neuropsychology and clinical populations will also be considered.
