The field of educational psychology

The field of educational psychology involves the study of memory, conceptual processes, and individual differences (via cognitive psychology) in conceptualizing new strategies for learning processes in humans. Educational psychology has been built upon theories of Operant conditioning, functionalism, structuralism, constructivism, humanistic psychology, Gestalt psychology, and information processing.
Educational Psychology has seen rapid growth and development as a profession in the last twenty years. School psychology began with the concept of intelligence testing leading to provisions for special education students, whom could not follow the regular classroom curriculum in the early part of the 20th century. However, "School Psychology" itself has built a fairly new profession based upon the practices and theories of several psychologists among many different fields. Educational Psychologists are working side by side with psychiatrists, social workers, teachers, speech and language therapists, and counselors in attempt to understand the questions being raised when combining behavioral, cognitive, and social psychology in the classroom setting.
