Developmental Trajectories of Ratio and Simple Magnitude Processing

4-5 years old, 2nd graders, 5th graders, and adults completed four types of non-symbolic ratio comparison tasks and magnitude tasks. Participants chose which of ratio or magnitude is larger between two stimuli.

在本次研究中，4至5岁的二年级学生、五年级学生以及成年人完成了四种不同类型的非符号比率比较任务和量级任务。参与者需从两个刺激中选择出比率或量级较大者。
