The persistence of learning over time through the storage and retrieval of information.
A clear memory of an emotionally significant moment or event.
The processing of information into the memory system - for example, by extracting meaning.
The retention of encoded information over time.
The process of getting information out of memory storage.
The immediate, initial recording of sensory information in the memory system.
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. Working memory is a similar concept that focuses more on the processing of briefly stored information.
The relatively permanent and limitless storehouse of the memory system.
Unconscious encoding of incidental information, such as space, time, and frequency, and of well-learned information, such as word meanings.
Encoding that requires attention and conscious effort.
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.
Serial Position Effect
Our tendency to recall best the last and first items in a list.
The encoding of picture images.
The encoding of sound, especially the sound of words.
The encoding of Meaning, including the meaning of words.
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.
Organizing items into familiar, manageable units; often occurs automatically.
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 with in 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.
Loss of memory.
Retention independent of conscious recollection. Also called procedural memory.
Memory of facts and experiences that one can consciously know and "declare" (also called declarative memory).
A neural center located in the limbic system that 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 fora second time.
The activation, often unconsciously, of particular associations in memory.
That eerie sense that "I've experienced this before." Cues form the current situation may subconsciously trigger retrieval of an earlier experience.
The tendency to recall experiences that are consistent with one's current good or bad mood.
The disruptive effect of prior learning on the recall of new information.
The disruptive effect of new learning on the recall of old information.
In psychoanalytic theory, the basic defense mechanism that banishes from consciousness anxiety-arousing thoughts, feelings, and memories.
Incorporating misleading information into one's memory of an event.
Attributing to the wrong source an event that we have experienced, heard about, read about, or imagined. (Also called source misattribution.) Source amnesia, along with the misinformation effect, is at the heart of many false memories.
