Cognitive psychology is characterized by being goal-oriented, problem-focused, and problem-solving from the very beginning. In some people's minds, failure is a sign of worthlessness or inferiority. This branch of psychology is concerned with analyzing how mental processes like perception, attention, thought, language, and memory operate, mainly through inferences from behavior, in addition to studying the phenomena themselves. In the 1940s and 1950s, cognitive approaches developed in response to contemporary behaviorism in the emphasis on unseen knowledge processes rather than observable behaviors directly observed, and the belief that stimulus and response are not simple and direct, but rather complex and mediated relationships. A result of its concentration on the higher mental processes contrasts with the typical approach of psychoanalysis, which emphasizes instincts, unconscious forces, and other unconscious mental processes. Many methods have recently influenced the relationship between cognitive psychology and computer science and artificial intelligence to information processing and information theory developed in computer science. In this paper, different approaches of Cognitive Psychology, concepts of behaviourism, perception and attention are illustrated. Different Object properties are identified between entities of psychology. Ontologies are used to build the relations between different relations identified to build a knowledge base. Protégé editor is used to implement Web ontology language for fundamentals of psychology in aspects of developmental, clinical, abnormal and social psychology to understand these concepts optimally.
