In contrast to previous findings, this study demonstrates that 11-month-old infants are able to learn the relationship between object material and object weight when exploring different objects that provided a systematic covariation of both object features. This guides their action in a subsequent preferential-reaching task.
与先前的发现相反，本研究表明，11 个月大的婴儿能够在探索不同的物体时学习到物体材料和物体重量之间的关系，这些物体提供了这两个物体特征的系统共变。这指导了他们在随后的优先接近任务中的行动。
