研究人员开发了一种新的方法来衡量没有自觉自我报告的经验的奖励价值. 这种使用强化学习 (RL) 的计算方法比传统的自我评估更好地预测行为.
科学领域:
- 认知神经科学 认知神经科学
- 决策科学 决策科学 决策科学
- 行为经济学是一种行为经济学.
背景情况:
- 人类的动机是由经验的感知奖励价值驱动的.
- 这些奖励值并不总是有意识地可访问的.
- 现有的方法通常依赖于主观的自我报告,这可能无法完全捕捉潜在的奖励过程.
研究的目的:
- 开发和验证一种用于测量经验的计算推断奖励值 (cRV) 的新方法.
- 评估cRV是否可以独立于有意识的自我报告来测量.
- 调查cRV,明确自我报告和行为预测之间的关系.
主要方法:
- 使用强化学习 (RL) 范式与计算建模相结合.
- 在两项涉及参与者观看图像 (正面与负面,有吸引力与没有吸引力的面孔) 的研究中测量了cRV.
- 将cRV与明确的自我报告措施和行为结果进行比较.
主要成果:
- 参与者对正面与负面图像以及有吸引力与不有吸引力的面孔的cRV较高,符合动机奖励理论.
- cRV受上下文因素 (图像熟悉/新性) 和个人差异 (吸引力偏好) 的影响.
- 虽然与自我报告相关,但cRV表现出对行为的优越预测能力,这表明它捕捉了非意识的奖励信号.
结论:
- 计算推断的奖励值 (cRV) 提供了经验驱动动力的有效和敏感的衡量标准.
- 这种基于RL的方法提供了超越意识意识的奖励过程的见解.
- 测量cRV对于理解各种科学领域的选择行为具有广泛的应用.

Decision Making: P-value Method
First, a specific claim about the population parameter is proposed. The claim is based on the research question and is stated in a simple form. Further, an opposing statement to the claim is also stated. These statements can act as null and alternative hypotheses: a null hypothesis would be a neutral statement while the alternative hypothesis can...
