Babies can categorize objects and actions, understand the cause and effect relationship between events, and see the goals in a movement. Recent studies on action representation and spatial concepts have shown that babies’ universal and language-general action representation productively changes with the learning of the mother tongue. For example, languages use prepositions to express the relationship between objects, i.e., in, on, under. However, languages also vary how they use these relations. One of the most significant studies suggests that babies can differentiate between concepts expressed with prepositions such as containment (in) and support (on). The Korean language specifies the nature of these containment and support relationships using the tightness of the relationship between objects: tight or loose. For example, a pencil in a pencil-size box represents a tight relationship, while a pencil in a big basket represents a loose relationship.
