人类可能表现出低于最佳的选择行为,选择随着时间的推移导致资源损失的选择. 这项研究重新检查了人类数据,在大多数情况下发现了最佳选择,但在其他情况下却发现了次优选择,挑战了以前的假设.
科学领域:
- 行为经济学是一种行为经济学.
- 动物认知 动物认知
- 决策心理学 决策心理学
背景情况:
- 低于最佳的选择行为,以资源损失为特征,在实验室环境中在物种中观察到.
- 最佳选择产生了更多的强化,但缺乏预测线索,而低于最佳的选择提供了更少的奖励,但提供了预测信号.
- 以前的研究表明,子和老鼠更喜欢低于最佳的选择,而人类则倾向于最佳的选择.
研究的目的:
- 重新评估人类的选择行为,使用强化衍生的最佳性定义.
- 研究人类决策是否与特定条件下预测的最佳或次优模式保持一致.
- 改进对人类次优选择行为的理解.
主要方法:
- 分析了之前发表的两个人类数据集,使用了强化衍生的最佳性定义.
- 观察到的选择行为与基于获得的强化比例的预测进行比较.
- 在不同的实验条件下检查选择模式.
主要成果:
- 人类选择行为在很大程度上与基于多种条件的强化结果的最佳预测一致.
- 在两个特定的实验条件下,参与者表现出对次优选择的显著偏好.
- 这些发现表明,在某些情况下,人类的选择行为可能低于最佳.
结论:
- 强化衍生的最佳性定义为评估人类选择行为提供了一个框架.
- 人类参与者可以表现出低于最佳的选择行为,这与之前的一些发现相反.
- 将选择行为与获得的强化比例进行评估,可以更准确地评估决策任务中的最佳性.
