Information Processing Theory The information processing theory is a cognitive approach to understanding how the human mind transforms sensory information. The model assumes that information that comes from the environment is subject to mental processes beyond a simple stimulus-response pattern. "Input" from the environment goes through the cognitive systems which is then measured by the "output". Information that is received can take several paths depending on attention, encoding, recognition, and storage. The central executive feature controls how much information is being processed, though more primitive sensory areas of the brain first accept environmental input. The theory looks at real time responses to presented stimuli and how the mind transforms that information. The model is used in several areas of research such as; cognitive development, neuroscience, social learning, and artificial intelligence. The Information Processing Model consists of three key functions: 1. Sensory memory 2. Working memory 3. Long-term memory Sensory memory helps people screen incoming information. Working memory helps people manage and store larger chunks of information, and perform visual-spatial mental operations. Long-term memory serves as a permanent repository, holding all sorts of information that can be accessed at a later time, enabling humans to continually build upon their knowledge base.
The Information Processing Theory and Instructional Model rely on three key principles: 1.
