Psychology is the science of understanding human behavior and cognition. It is relevant to education in several ways: 1. Psychology helps define and clarify the aims of education by showing what outcomes can and cannot be achieved. 2. Psychology contributes to understanding students' cognitive processes and individual differences, including various types of intelligence like verbal, logical-mathematical, and bodily-kinesthetic intelligence. 3. Student characteristics like intelligence, learning styles, and diversity impact how students learn and what teaching methods are most effective. Psychology provides insights to help teachers address individual student needs.
