Overview of the forms and functions of memory in the sciences In psychology, memory is the process in which information is encoded, stored, and retrieved. Encoding allows information that is from the outside world to reach our senses in the forms of chemical and physical stimuli. In this first stage we must change the information so that we may put the memory into the encoding process. Storage is the second memory stage or process. This entails that we maintain information over periods of time. From an information processing perspective there are three main stages in the formation and retrieval of memory: The loss of memory is described as forgetfulness, or as a medical disorder, amnesia. Sensory memory Sensory memory holds sensory information for a few seconds or less after an item is perceived. There are three types of sensory memories. Short-term memory Long-term memory Models Models of memory provide abstract representations of how memory is believed to work.
