Abstract
Schleihauf et al. (2025) provided a compelling set of experiments that demonstrate that chimpanzees will change their choices when given new evidence about one or more of those choice options. Although chimpanzees clearly update expectations about choice values, it is less certain that they must be updating beliefs to do that. (PsycInfo Database Record (c) 2026 APA, all rights reserved).
Schleihauf et al.(2025)提供了一组令人信服的实验,这些实验表明,当黑猩猩得到关于其中一个或多个选择选项的新证据时,它们会改变自己的选择。虽然黑猩猩很清楚地更新了对选择价值的预期,但它们是否一定是在更新信念来做到这一点还不太确定。(PsycInfo数据库记录(c) 2026 APA,版权所有)。
