Cognitive psychology is the scientific study of the mind as an information processor.
Cognitive psychologists try to build up cognitive models of the information processing that goes on inside people’s minds, including perception, attention, language, memory, thinking, and consciousness.
Cognitive psychology became of great importance in the mid-1950s. Several factors were important in this:
~Dissatisfaction with the behaviorist approach in its simple emphasis on external behavior rather than internal processes.
~The development of better experimental methods.
~Comparison between human and computer processing of information.
~The emphasis of psychology shifted away from the study of conditioned behavior and psychoanalytical notions about the study of the mind, towards the understanding of human information processing, using strict and rigorous laboratory investigation.
