activated memory that holds a few items briefly, such as the seven digits of a phone number while dialing, before the information is stored or forgotten
the relatively permanent and limitless storehouse of the memory system. Includes knowledge, skills, and experiences.
a newer understanding of short-term memory that involves conscious, active processing of incoming auditory and visual-spatial information, and of information retrieved from long-term memory.
unconscious encoding of incidental information, such as space, time, and frequency, and of well-learned information, such as word meanings.
the conscious repetition of information, either to maintain it in consciousness or to encode it for storage.
the tendency for distributed study or practice to yield better long-term retention than is achieved through massed study or practice.
mental pictures; a powerful aid to effortful processing, especially when combined with semantic encoding
memory aids, especially those techniques that use vivid imagery and organizational devices.
a momentary sensory memory of visual stimuli; a photographic or picture-image memory lasting no more than a few tenths of a second.
a momentary sensory memory of auditory stimuli; if attention is elsewhere, sounds and words can still be recalled within 3 or 4 seconds
long-term potentiation (LTP)
an increase in a synapse's firing potential after brief, rapid stimulation. Believed to be a neural basis for learning and memory.
explicit (declarative) memory
memory of facts and experiences that one can consciously know and "declare."
a neural center that is located in the limbic system and helps process explicit memories for storage
a measure of memory in which the person must retrieve information learned earlier, as on a fill-in-the-blank test.
a measure of memory in which the person need only identify items previously learned, as on a multiple-choice test.
a memory measure that assesses the amount of time saved when learning material for a second time.
the tendency to recall experiences that are consistent with one's current good or bad mood.
in psychoanalytic theory, the basic defense mechanism that banishes from consciousness anxiety-arousing thoughts, feelings and memories.
