动态环境中的群体觅食
Group Foraging in Dynamic Environments
摘要：
以前的人类觅食实验表明，人类群体经常与环境资源不匹配，就像其他动物物种一样。在这个实验中，我们测试了当环境状态不确定时，人类是否也选择性地依赖他人作为信息源，我们还测试了其他觅食者成功的明显信号是否会影响群体匹配行为和群体对不断变化的环境的适应。研究结果表明，在特定条件下，参与者依赖社会信息，但主要是受他们对食物位置的个人评估的影响，而不是其他觅食者的成功。
英文摘要：
Previous human foraging experiments have shown that human groups routinely undermatch environmental resources much like other animal species. In this experiment, we test whether humans also selectively rely on others as information sources when the environmental state is uncertain, and we also test whether overt signals of other foragers' success influences group matching behavior and group adaptation to a changing environment. The results show evidence of reliance on social information in specific conditions, but participants were primarily influenced by their individual assessments of food location rather than the success of other foragers.
