Information Processing and Human Memory

Information processing is a cognitive learning theory that helps explain how individuals acquire, process, store, and retrieve information from memory. The cognitive architecture that facilitates the processing of information consists of three components: memory stores, cognitive processes, and metacognition. The memory stores are sensory memory, a virtually unlimited store that briefly holds stimuli from the environment in an unprocessed form until processing begins; working memory, the conscious component of our information processing system, limited in both capacity and duration, where knowledge is organized and constructed in a form that makes sense to the individual; and long-term memory, a vast and durable store that holds an individual’s lifetime of acquired information. Information is moved from sensory memory to working memory using the cognitive processes attention, selectively focusing on a single stimulus, and perception, the process of attaching meaning to stimuli. After information is organized in working memory so it makes sense to the individual, it is represented in long-term memory through the process of encoding, where it can later be retrieved and connected to new information from the environment. Metacognition is a regulatory mechanism that facilitates the use of strategies, such as chunking, automaticity, and distributed processing, that help accommodate the limitations of working memory, and schema activation, organization, elaboration, and imagery that promote the efficient encoding of information into long-term memory. Information processing theory has implications for our daily living ranging from tasks as simple as shopping at a supermarket to those as sophisticated as solving complex problems.
