The first Principle states that Humans are information processors. Cognition refers to the mental tasks or thinking involved in human behavior. Thinking may involve memory, attention, perception, language and decision making at any one time. Cognitive psychologists see these cognitions are active systems; In between taking in and responding to information a number of processes are at work. Information can be transformed; reduced, elaborated, filtered, manipulated, selected, organized, stored and retrieved Therefore the human mind is seen as active system processing information, and cognitive psychologist’s aim to study these processes. Central to this information processing approach is the computer metaphor. One of the difficulties facing cognitive psychologists is that they were trying to study processes that are not directly observable. Consequently the computer revolution of the 1950 provided the terminology and metaphor they needed. People, like computers, acquire information from the environment (input). Both people and computers store information and retrieve it when applicable to current tasks; both are limited in the amount of information they can process at a given time; both transform information to produce new information; both return information to the environment (output). This information processing approach was adopted by Atkinson and Shiffrin in their Multistore Model of memory (1968). This model sees memory as an active process. Information flows in through the sensory stage (input). It then flows to the short-term memory before it is transferred to long term memory where it can be stored and later retrieved. A further example of information processing is the organization of information into schemas in the LTM. Schemas are mental models of the world. Information in LTM is stored in interrelated networks of these schemas and these
