Flavell, John H.

John H. Flavell is a renowned developmental psychologist known for his research on cognitive development in children. He studied how children's thinking and understanding of the world evolve, particularly their awareness of their own mental processes—referred to as "metacognition." Flavell's work helped explain how kids develop skills like perspective-taking, understanding others' thoughts, and recognizing their own learning processes, contributing significantly to educational practices and developmental psychology.
