An important aspect of executive functioning is the ability to flexibly switch between behavioral rules. This study explored how considering the multidimensionality of objects affects behavioral rule switching in 3-year-old children. In Study 1 (N = 40), children who participated in a brief game separating and aggregating an object's dimensions (i.e., color and shape) showed improved performance on the Dimensional Change Card Sort (DCCS), a measure of behavioral rule switching, relative to controls. In Study 2 (N = 80) DCCS performance improved even when the initial practice involved a different dimension (pattern and shape). Thus, practice thinking about multidimensionality can affect 3-year-olds' DCCS performance and therefore may play an important role in the development of flexible thinking.
执行功能的一个重要方面是在行为规则之间灵活切换的能力。本研究探讨了考虑物体的多维性如何影响三岁儿童的行为规则切换。在研究1（N = 40）中，参与一个短暂游戏（该游戏将物体的维度，即颜色和形状，进行分离和整合）的儿童，相对于对照组，在维度变化卡片分类任务（DCCS，一种行为规则切换的测量方法）中表现出了更好的成绩。在研究2（N = 80）中，即使最初的练习涉及不同的维度（图案和形状），DCCS的成绩仍有所提高。因此，对多维性进行思考的练习可以影响三岁儿童的DCCS成绩，进而可能在灵活思维的发展中发挥重要作用。
