成年人使用2个独立的维度来表示二维空间中的点的位置。他们编码的位置沿着这些维度都在细粒度级别和分类。在报告位置时，它们对细粒度和分类信息进行联合收割机组合和加权。在实验1中，我们发现，5岁的儿童使用相同的2个独立的尺寸在细粒度的空间编码的位置在一个圆圈中的成年人所使用的-半径和角度。然而，分类编码和分层组合仅见于桡骨，在5年和7年时。成人模式，其中角度以及半径是分层编码，出现了9年。实验2表明，没有什么本质上困难的角度信息的分类编码，当角度是唯一的维度进行编码，年龄较小的儿童使用分层编码。e维分层编码的变化可能是由于认知负荷因素和分配参考框架能力的变化。
Adults represent the location of a point in a 2-dimensional space using 2 independent dimensions. They encode location along these dimensions both at a fine-grained level and categorically. In reporting location, they combine and weight the fine-grained and categorical information. In Experiment 1, we found that children as young as 5 years use the same 2 independent dimensions in fine-grained spatial coding of location in a circle as are used by adults--radius and angle. However, categorical coding and hierarchical combination are seen only for radius, at both 5 and 7 years. The adult pattern, where angle as well as radius is coded hierarchically, emerges by 9 years. Experiment 2 shows that there is nothing intrinsically difficult about the categorical coding of angular information; when angle is the only dimension to be encoded, younger children use hierarchical coding. Changes in e-dimensional hierarchical coding may be due to cognitive load factors and to changes in ability to assign frames of reference.
