Chase is a baby with a slow-to-warm-up temperament. When his parents take him to a new environment (e.g. a new friend's house), they let him have time to adjust and don't force him to interact too quickly. This match between Chase's temperament and his environment is called nomothetic correlation goodness of fit social referencing concrete operations

The situation described involves the concept of how well an individual's temperament matches their environment, particularly in terms of allowing time for adjustment. This is best described by the term **goodness of fit**. **Goodness of fit** refers to the compatibility between a child's temperament and the demands and expectations of their environment. In this case, Chase's slow-to-warm-up temperament is being accommodated by his parents, who allow him the time he needs to adjust to new situations. The other options do not fit this context: - **Nomothetic correlation** refers to general laws or principles that apply to groups rather than individuals. - **Social referencing** involves looking to others for cues on how to react in uncertain situations. - **Concrete operations** is a stage in cognitive development according to Piaget, where children begin to think logically about concrete events. Thus, the correct answer is **goodness of fit**.
