张航，研究员

 

研究兴趣：

张航实验室（“计算与决策实验室”）使用行为实验、计算建模和无创脑成像技术研究人类的感知觉和认知系统中的各种决策问题，在心理学、认知神经科学、统计决策理论和经济决策之间建立桥梁。我们关注不同领域的判断和决策背后普适的神经计算原理，结合计算建模和脑成像来破解脑中的运算。

 

我们的许多研究都围绕着“不确定性”展开。如果没有不确定性，世界上大部分的决策问题将变得无比简单。然而，不确定性无处不在，概率运算因而成为大脑的一项重要功能。我们试图回答的问题包括：大脑如何利用有限的认知资源进行高效的概率运算？如何为自身和外部世界中的不确定性建立概率模型？有着怎样的先验信念或偏见？又能带给人工智能什么启示？
