Optimal or suboptimal, Rahnev & Denison (R&D) rightly argue that this ill-defined distinction is not useful when comparing models of perceptual decision making. However, what they miss is how valuable the focus on optimality has been in deriving these models in the first place. Rather than prematurely abandon the optimality assumption, we should refine this successful normative hypothesis with additional constraints that capture specific limitations of (sensory) information processing in the brain.
拉赫内和丹尼森（R&D）认为，在比较知觉决策模型时，这种定义不明确的区分没有实际意义，他们的观点是正确的。然而，他们忽略了一个重要事实，即关注最优化对于推导出这些模型具有非常重要的价值。因此，我们不应过早地摒弃最优化假设，而应通过增加额外的约束条件来改进这一成功的规范性假设，以捕捉大脑（感官）信息处理的特定局限性。
