215310147storagethe retention of encoded information

215310149sensory memorythe immediate, very brief recording of sensory information in the memory system
215310150short-term memoryactivated memory that holds a few items briefly
215310151long-term memorythe relatively permanent and limitless storehouse of the memory system
215310152working memorya newer understanding of short-term memory that involves consious, active processing of incoming auditory and visual-spatial information and of information retrieved from long-term memory
215310153automatic processingunconsious encoding of incidential information, such as space, time and frequency
215310154effortful processingencoding that requires attention and concious effort
215310155rehearsalthat concious repetion of information, either to maintain it in consiousness or to encode it for storage
221929883selective attentionthe focusing of conscious awareness on a particular stimulus, as in the cocktail party effect
221929884inattentional blindnessfailing to see visible objects when our attention is directed elsewhere
221929885elaborative rehearsallinking stimuli to each other in a meaningful way to improve retention of information in short-term memory
221929886spacing effectthe tendency for distributed study or practice to yield better long-term retention than is achieved through massed study or practice
221929887self reference effectthe tendency to process efficiently and remember well information related to oneself
221929888primacy effectThe tendency to show greater memory for information that comes first in a sequence.
221929889maintenance rehearsalA system for remembering involving repeating information to oneself without attempting to find meaning in it
221929890visual encodingthe encoding of picture images
221929891acoustic encodingthe encoding of sound, especially the sound of words
221929892semantic encodingthe encoding of meaning, including the meaning of words
221929893imagerylanguage that appeals to the senses
221929894mnemonicsmemory aids, especially those techniques that use vivid imagery and organizational devices
221929895method of locia mnemonic technique that involves associating items on a list with a sequence of familiar physical locations
221929896chunkingorganizing items into familiar, manageable units; often occurs automatically
221929897next in line effectwhen people go around in a circle saying words or their names, their poorest memories are for what was said by the person just before them

221929899schemaa concept or framework that organizes and interprets information
221929900iconic memorya momentary sensory memory of visual stimuli; a photographic or picture-image memory lasting no more than a few tenths of a second

221929902haptic memoryencoding by sense of touch. hand remember how your soft blanket feels
221929903Karl Lashleyfound that memories do not reside in single, specific spots; forgetting occurs when experiences interfere with our retrieval and physical memory trace decays
221929904engramLashley's term for physical trace or etching of memory in the brain
221929905long-term potentationan increase in a synapse's firing potential after brief, rapid stimulation. Believed to be a neural basic for learning and memory
221929906Eric KandelStudied the sea slug Aplysia and posited that learning and memory are evidenced by changes in synapses and neural pathways.
221929907amnesialoss of memory
221929908implicit memoryretention independent of conscious recollection
221929909explicit memorymemory of facts and experiences that one can consciously know and "declare"
221929910episodic memorymemory for episodes in your own life
221929911semantic memorymemory for general knowledge
221929912eidetic memorythe ability to remember with great accuracy visual information on the basis of short-term exposure
221929913hippocampusa neural center located in the limbic system that helps process explicit memories for storage
221929914cerebellumthe "little brain" attached to the rear of the brainstem; it helps coordinate voluntary movement and balance

221929916anterograde amnesiaInability to store new memories after a traumatic event
221929917psychogenic amnesialoss of memory resulting from repression of psychological, emotional trauma or damage
221929918organic amnesialoss of memory resulting from physical trauma or damage to the brain
221929919recallA measure of memory in which the person must retrieve information learned earlier, as on a fill-in-the-blank test.
221929920recognitiona measure of memory in which the person need only identify items previously learned, as on a multiple-choice test
221929921relearninga memory measure that assesses the amount of time saved when learning material for a second time
221929922deja vuthat eerie sense that "I've experienced this before." Cues from the current situation may subconsciously trigger retrieval of an earlier experience.

221929924state-dependent memoryLearning that takes place in one situation or "state" is generally better remembered later in a similar situation or state.
221929925Hermann Ebbinghausthe first person to study memory scientifically and systematically; used nonsense syllables and recorded how many times he had to study a list to remember it well
221929926proactive interferencethe disruptive effect of prior learning on the recall of new information
221929927repressionin psychoanalytic theory, the basic defense mechanism that banishes from consciousness anxiety-arousing thoughts, feelings, and memories
