Psych unit 9 memory Flashcards
memory
the persistence of learning over time through the storage and retrieval of information.
encoding
the processing of informa- tion into the memory system—for exam- ple, by extracting meaning.
storage
the retention of encoded information over time.
retrieval
the process of getting information out of memory storage.
sensory memory
the immediate, very brief recording of sensory information in the memory system.
short-term memory
activated memo- ry that holds a few items briefly, such as the seven digits of a phone number while dialing, before the information is stored or forgotten.
long-term memory
the relatively per- manent and limitless storehouse of the memory system. Includes knowledge, skills, and experiences.
working memory
a newer under- standing of short-term memory that focuses on conscious, active processing of incoming auditory and visual-spatial information, and of information retrieved from long-term memory.
automatic processing
unconscious encoding of incidental information, such as space, time, and frequency, and of well-learned information, such as word meanings.
effortful processing
encoding that requires attention and conscious effort.
rehearsal
the conscious repetition of information, either to maintain it in con- sciousness or to encode it for storage.
spacing effect
the tendency for dis- tributed 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
::visual encoding
the encoding of pic- ture images.
acoustic encoding
the encoding of sound, especially the sound of words.
:semantic encoding
the encoding of meaning, including the meaning of words.
::imagery
mental pictures; a powerful aid to effortful processing, especially when combined with semantic encoding.
mnemonics
memory aids, especially those techniques that use vivid imagery and organizational devices.
chunking
organizing items into famil- iar, manageable units; often occurs automatically.
::iconic memory
a momentary sensory memory of visual stimuli; a photographic or picture-image memory lasting no more than a few tenths of a second.
echoic memory
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.
flashbulb memory
a clear memory of an emotionally significant moment or event.
amnesia
the loss of memory.
