Explanation:
Postformal thinking is a stage of cognitive development that comes after formal operations, where individuals exhibit practical, realistic, and individualistic thinking, understanding complexities of various perspectives, and making decisions based on prior experience rather than solely on what others think.
Adolescent egocentrism is a concept where adolescents attribute unlimited power to their thoughts and demonstrate a heightened self-focus, gradually learning the limits of their thoughts as they take on adult roles.
Stereotyping and prejudice involve making assumptions or holding preconceived ideas about groups or communities, which can hinder learning about cultural differences and lead to ethnocentric tendencies and assumptions of similarity.
