Researchers have recently developed brief methods to measure discounting. One brief method uses 5-trial adjusting-delay or -probability tasks. These tasks have provided similar rates of discounting to traditional tasks with monetary gains, but the accuracy with losses have been mixed. Differences in loss discounting across tasks may have been due to the amounts used in previous experiments. Therefore, we had undergraduate students (N = 93) complete two types of discounting tasks across losses ranging from $10 to $10 million. Consistent with previous research using traditional measures, discounting did not differ between tasks or across amounts used. 5-trial discounting tasks of losses provide similar rates of discounting compared to traditional adjusting amount tasks for both probability and delay.
研究人员最近开发了测量折扣的简短方法。一种简短方法使用5次试验的调整延迟或概率任务。这些任务得出的折扣率与涉及金钱收益的传统任务相似，但在涉及损失时的准确性参差不齐。不同任务之间损失折扣的差异可能归因于先前实验中使用的金额。因此，我们让93名本科生完成了两种类型的折扣任务，涉及从10美元到1000万美元不等的损失。与先前使用传统测量方法的研究一致，任务之间或所使用的金额之间的折扣没有差异。与传统的调整金额任务相比，损失的5次试验折扣任务在概率和延迟方面都提供了相似的折扣率。
