Fundamentals of Cognitive Psychology provides a concise yet comprehensive introduction to the scientific study of human mental processes. Ronald T. Kellogg explains how people perceive, attend to, remember, think, solve problems, make decisions, and use language. Written primarily for undergraduate students, the book combines classical theories with current research to present a clear understanding of cognitive functioning. The text explores major topics including perception, attention, memory systems, autobiographical memory, knowledge representation, language, reasoning, decision making, and problem solving. A key feature of the second edition is its integration of findings from cognitive neuroscience, including brain imaging techniques such as PET and fMRI, to explain the neural basis of cognition. Practical examples and cognitive demonstrations help students connect theoretical concepts with everyday experiences. The book emphasizes how cognitive psychology contributes to understanding learning, intelligence, communication, and human behaviour. It is an essential textbook for students of psychology, education, neuroscience, and related disciplines, providing both foundational knowledge and insight into contemporary research in cognition.
