Cognitive psychology is the scientific exploration of mental processes, involving phenomena such as attention, perception, memory, problem-solving, and language use. Within this discipline, cognition is often viewed through the lens of the dual process theory, which posits two styles of processing, namely, intuition and reasoning. Cognitive psychology extends its influence to various fields, including economics, developmental psychology, abnormal psychology, personality psychology, and social psychology. The principles of behaviorism have been integrated with cognitive psychology to develop cognitive-behavioral therapy (CBT). This therapeutic intervention aims to enhance mental health and address conditions such as depression and anxiety by modifying cognitive patterns and behaviors.
