THE HUMAN MEMORY Introduction The human memor

The human memory can be viewed as an information processing system which is divided into three storage structures which correspond to a stage of processing stimulus. Sensory register, (registers for the five senses, visual, hearing, touch, smell, and taste; vision and hearing registers have been studied the most) is the name of the site of registration of initial stimulus presentation; pattern recognition or naming, is a process that now takes place, contact is made between the information in the sensory register and previously acquired knowledge. The stimulus is now encoded so that it can be passed to the next stage, short-term memory (STM). An item in the visual register decays in a second; items are now maintained by a holding process called rehearsal, which renews the material so decay is never complete; without rehearsal, the information is lost in STM. In STM, only a few stimuli can be held simultaneously; it has room for about seven items, called the memory span. The loss of additional information is one type of forgetting. The third storage structure is long-term memory (LTM), a permanent stor

1980). Memory abilities vary among individuals; differences in intelligence and memory appear to be intertwined. Individual differences are demonstrated in varying abilities for speed with which one can derive the names of verbal symbols and retrieve from STM, and amounts that can be retained in STM; differences are also found regarding amounts of information in LTM, and processes such as those used in encoding and retrieving from memory. Memory varies within the individual as well. Changes in emotional and physical states, can effect the memory system. Illness, emotional trauma, drug ingestion, and aging may result in fluctuations in memory (Klatzky, 1980). Memory Organization/Psychological & Neural Studies Funahashi and Kubota (1994) studied the relationship between the prefrontal cortex and working memory, a proposed type of short-term memory. Both human and animal studies have demonstrated that a particular type of memory is related to a particular brain structure, which can be used as a model for understanding the neuronal mechanisms of memory. The authors currently present a modular model based on neurophysiological results and discuss spatial working memory processes in the prefrontal cortex. The notion of tw
