几何模块论的局限性——来自梯形实验的证据

Limitation of the Geometric Module: Evidence from Children’s Reorientation Behavior in a Trapezoidal Room

以往研究表明幼儿主要依赖几何信息进行再定向，但这些研究大多使用矩形空间。在本研究中，幼儿所处的空间为几何信息更丰富，目标物体所在位置确定的梯形。结果发现，幼儿并不会利用新增的几何信息确定目标物体，仍然去正确位置的对角寻找，表现出的寻找模式与矩形空间一样，这说明幼儿在空间再定向任务中对几何信息的利用很有限。此外，录像分析的结果发现，幼儿在面向梯形两底边时会更多地且径直地走向正确位置或对角，这种寻找过程上的特点表明他们可能基于空间轴朝向结合左右方位感表征物体位置。

Humans and animals are able to orient themselves to an environment. Previous studies have demonstrated that young children’s reorientation behaviors are mainly guided by the geometric information of their environment. Children often reorient themselves according to the shape of the testing room and not in accordance with the room’s non-geometric properties. While previous studies typically used rectangular testing rooms that provided unique geometric information， we used a trapezoidal testing ro
