memory
[mem´o-re] the mental faculty that enables one to retain and recall previously experienced sensations, impressions, information, and ideas. The ability of the
brain to retain and to use knowledge gained from past experience is essential to the process of learning. Although the exact way in which the brain remembers is not completely understood, it is believed that a portion of the temporal lobe of the brain, lying in part under the temples, acts as a kind of memory center, drawing on memories stored in other parts of the brain.
impaired memory a nursing diagnosis accepted by the North American Nursing Diagnosis Association, defined as inability to remember bits of information or behavioral skills.
immunologic memory the capacity of the
immune system to respond more rapidly and strongly to a subsequent antigenic
challenge than to the first exposure. See also memory
cells and
immune response.
long-term memory the aspect of memory in which knowledge is stored permanently, to be activated when cued; it is theoretically unlimited in capacity.
recent memory the ability to recall events from the immediate past.
remote memory the ability to recall events from the distant past.
screen memory a consciously tolerable memory serving to conceal or “screen” another memory that might be disturbing or emotionally painful if recalled.
short-term memory what one is conscious of at a given moment; in contrast to long-term memory it is of limited capacity (about seven items) and will be lost unless rehearsed and related to information in long-term memory.
