Educational psychology is a fairly new and growing field of study. Although it can date back as early as the days of Plato and Aristotle, educational psychology was not considered a specific practice. It was unknown that everyday teaching and learning in which individuals had to think about individual differences, assessment, development, the nature of a subject being taught, problem solving, and transfer of learning was the beginning to the field of educational psychology. These topics are important to education and, as a result, they are important in understanding human cognition, learning, and social perception.
