encoding
processing of information into the memory system- for example, extracting meaning
storage
retention of encoded information over time
retrieval
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 memory that holds a few items briefly, such as the seven digits of a phone number while dialing
long-term memory
relatively permanant and limitedless storehouse of the memory system
working memory
newer understanding of short-term memory that involves conscious, active processing of incomine auditory and visual-spatial information
automatic processing
unconscious encoding of incidental information, such as space, time, and frequence
effortful processing
encoding that requires attention conscious effort
rehearsal
conscious repetition of information, either to maintain it in consciousness or to encode it for storage
spacing effect
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
visual encoding
encoding of picture images
acoustic encoding
encoding of sound, especially the sound of words
semantic encoding

amnesia
loss of memory
implicit memory
