Cognitive psychology is a branch of psychology that focuses on understanding the mental processes involved in perception, memory, attention, language, and thinking. It is a relatively new subfield that emerged in the 1950s and 1960s as a reaction to behaviorism.

One of the most important psychologists associated with the development of cognitive psychology is Ulric Neisser. Neisser was born in Germany in 1928 and later emigrated to the United States. He studied psychology at Harvard University under the supervision of George Miller, who was himself an influential figure in cognitive psychology.

Neisser’s seminal contribution to cognitive psychology was his book “Cognitive Psychology”, which was published in 1967. This book is widely regarded as one of the most important works in the history of cognitive psychology and helped to establish it as a distinct field within psychology.

In his book, Neisser argued that mental processes could not be reduced to simple stimulus-response associations or reflexes. Instead, he proposed that humans have an active role in processing information from their environment and that this processing involves complex mental operations such as attention, perception, memory, and problem-solving.

Neisser also introduced the concept of “cognition” as a general term for all mental processes involved in perception and thought. He argued that cognition should be studied using a variety of methods including experimentation, observation, introspection, and computer modeling.

Neisser’s work had a profound impact on the field of psychology and paved the way for further developments in cognitive science. Today, cognitive psychology is one of the most active areas of psychological research with many applications in fields such as education, medicine, artificial intelligence, and neuroscience.

In conclusion, Ulric Neisser is one of the most important psychologists associated with the development of cognitive psychology. His book “Cognitive Psychology” helped to establish this field as a distinct area within psychology and his ideas continue to influence research today. Cognitive psychology has come a long way since the 1960s, but Neisser’s legacy lives on as one of the founding figures of this fascinating field.
