Ulric Neisser was a prominent psychologist known as the 'father of cognitive psychology,' who played a critical role in the transition from behaviorism to cognitive science. He emphasized the importance of studying internal mental processes, such as perception, memory, and problem-solving, and his work helped to shape modern cognitive psychology by challenging the behaviorist perspective that dominated prior to the cognitive revolution. Neisser's influential book, 'Cognitive Psychology,' published in 1967, laid the groundwork for future research in the field and introduced concepts that remain integral to cognitive studies today.
