Final answer:
Children around the ages of 12-14 years begin to describe themselves using more abstract, psychological constructs rather than concrete behaviors or attributes.
Step-by-step explanation:
Children around the age of 12-14 years tend to describe themselves in more abstract ways, shifting from concrete descriptions of behavior to trait-like psychological constructs. At earlier developmental stages, children’s self-concepts are more concrete and based on physical attributes, behaviors, and simple traits. For instance, between 6 and 8 years old, children begin to see themselves in terms of group memberships. As development progresses, young adolescents around 12-14 years old can reflect on their traits more abstractly and compare themselves in more complex psychological terms, formulating their identity based on a more complex understanding of traits and their place within social contexts.
