- 设计了两个实验环境:一个有利于同质分配,另一个有利于波动分配.
- 测量波动作为偏离同质分配和与理想分配器模型相比的偏差.
主要成果:
- 参与者的行为波动超过最佳,但适应能力和环境.
- 识别了顺序策略,如保存以后和奖励历史依赖的选择.
- 一个扩展的最佳分配器模型显示,波动可以增强信息获取,避免风险和寻找.
结论:
- 行为波动虽然对即时表现有轻微影响,但在动态环境中提供长期优势.
- 这些策略反映了超出简单奖励最大化的适应性决策.

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...
