Memory Processses Essay examples - 1268 Words

Memory Processes The human capacity for memory is unknown, and the process for remembering is an invisible, and therefore, an unsubstantiated concept. A discussion regarding the concepts of short-term, working, and long-term memory precedes an explanation of the encoding and retrieval in the memory processes. An evaluation of the variables associated with encoding and retrieval provides an understanding of the results from an online self-administered memory test. Although online memory assessments provide an entertaining experience, the concept of memory and the factors influencing memory are too complex to depend on such assessments and individuals questioning their memory related abilities should seek the guidance of a health†¦show more content†¦In addition, Wang, Vijayraghavan, Goldman-Rakic, (2004) further established the prefrontal cortex as the location of working memory using neuroimaging to assert the engagement of prefrontal neurons when primates conducted working memory related ta sks. Short-term memory has significant limitations in both rate of forgetting (duration) and memory span (number of items the individual can remember). Humans use short-term memory to hold pieces of information for relatively short periods. Without rehearsal, the information is quickly lost and irretrievable. In fact, without rehearsal, information is forgotten within 30 seconds, and memory span for the average person is about 7 items or a phone number without the area code (Terry, 2009). That does not mean it is impossible to retain a phone number with and area code in short-term memory. Other factors influence short-term and working memory. The speed at which the individual can pronounce and retrieve the list of items is influential in the number of items he or she can hold in short-term memory (Cowan, Wood, Wood, Keller, Nugent, Keller, 1998). Humans can also use chunking to expand their ability to retain information. For example, the individual may hold a phone number in short-term as 800-436-40-83. This use of the area code and first three digits as a single item makeShow MoreRelatedAmmonium Sulfate From Waste Water3280 Words   |  14 Pages2.1.4. Reverse Osmosis 7 2.2.
