How does aging affect memory?<\/h1>\r\n\"Affectionate\r\n

The Sensory Register<\/h2>\r\nAging may create small decrements in the sensitivity of the sensory register.\u00a0And, to the extent that a person has a more difficult time hearing or seeing, that information will not be stored in memory.\u00a0This\u00a0is an important point, because many older people assume that if they cannot remember something, it is because their memory is poor.\u00a0In fact, it may be that the information was never seen or heard.\r\n

The Working Memory<\/h2>\r\nOlder people have more difficulty using memory strategies to recall details (Berk, 2007).\u00a0As we age, the working memory loses some of its capacity.\u00a0This\u00a0makes it more difficult to concentrate on more than one thing at a time or to keep remember details of an event.\u00a0\u00a0However, people compensate for this by writing down information and avoiding situations where there is too much going on at once to focus on a particular cognitive task.\r\n

The Long-Term Memory<\/h2>\r\nThis type of memory involves the storage of information for long periods of time. Retrieving such information depends on how well it was learned in the first place rather than how long it has been stored. If information is stored effectively, an older person may remember facts, events, names and other types of information stored in long-term memory throughout life.\u00a0 The memory of adults of all ages seems to be similar when they are asked to recall names of teachers or classmates.\u00a0And older adults remember more about their early adulthood and adolescence than about middle adulthood (Berk, 2007). Older adults retain\u00a0semantic memory\u00a0or the ability to remember vocabulary.\r\n\r\nYounger adults rely more on mental rehearsal strategies to store and retrieve information.\u00a0Older adults focus rely more on external cues such as familiarity and context to recall information (Berk, 2007).\u00a0And they are more likely to report the main idea of a story rather than all of the details (Jepson & Labouvie-Vief, in Berk, 2007).\r\n\r\nA positive attitude about being able to learn and remember plays an important role in memory.\u00a0When people are under stress (perhaps feeling stressed about memory loss), they have a more difficult time taking in information because they are preoccupied with anxieties.\u00a0 Many of the laboratory memory tests require compare the performance of older and younger adults on timed memory tests in which older adults do not perform as well.\u00a0However, few real life situations require speedy responses to memory tasks.\u00a0Older adults rely on more meaningful cues to remember facts and events without any impairment to everyday living.\r\n
