主要目标：本研究采用时间折扣范式和标准化冲动性问卷对一组脑损伤患者和年龄匹配的对照组进行了初步研究，方法和程序：被试被要求在未来特定时间可获得的较大奖励和立即可获得的较小奖励之间进行选择。也就是说，奖励的主观价值随着延迟的增加而降低。然而，TBI组折扣比对照组，这表明他们的决策是更加impulse.Conclusion：结果表明，时间贴现范式可能是一个有用的方法，评估决策后头部创伤，特别是在案件中的能力作出决定的经济奖励是一个问题，或在资金管理方面一般。
Primary objective: This study reports on a pilot study using a temporal discounting paradigm and a standardized impulsivity questionnaire to examine decision-making in a group of brain injured patients and age matched controls.Methods and procedures: Participants were asked to choose between a larger reward available at a specified time in the future and smaller reward available immediately.Outcome and results: Each of the two groups demonstrated temporal discounting; that is, the subjective value of the reward decreased with increasing delay. However, the TBI group discounted more than the controls, suggesting that their decision-making was more impulsive.Conclusion: The results suggest that a temporal discounting paradigm might be a useful method of assessing decision-making after head trauma, especially in cases where capacity to make decisions about financial awards is an issue or in respect of money management generally.
