what is memory
the process by which we retain and recall information about events that have happened in the past
what are the two types of memory
long term
short term
what is short term memory
your memory for immediate events, disappears if not rehearsed
what is long term memory
your memory for events that have happened in the past from 2 mintues - 100 years ago
what does the sensory register do
stores a huge amount of information from our senses for a very brief amoutn of time
how long does the sensory register store its information
half a second
what is capacity
the amount of information that can be stored
what is duration
the length of time information can be held in the memory store
what is coding
the format in which information is stored in the memory stores
what is acoustic coding
information stored in the form of sounds
what is semantic coding
information stored in the form of the meaning of the experience
what type of coding is long term memory
semantic
what type of coding is short term memory
acoustic
where does the sensory register get its information from
the sense organs
is the sensory register under cognitive control
no
what must happen to information in the sensory register for it to be passed on to the next store
must be paid attention to
what are the five sensory stores in the sensory register (coding)
iconic
echoic
haptic
gustatory
olfactory
what evidence is there for the coding of the sensory register
register retains iconic info for a few miliseconds, echoic info for 2-3 seconds
who found evidence for the coding of the sensory register
crowder
who found evidence for the capacity of the sensory register
sperling
what was sperling’s study for the capacity of the sensory register
studied iconic store
- flashed 3x4 gird of letters for 1/20th second
- asks participants to recall letters of one row using tone (high/med/low)
what evidence is there for the capacity of the sensory register
sperling - recall of letters was 76% average, therefore all the information was there so capacity is large
what is the capacity of each store of the sensory register
very large - its information is unprocessed, highly detailed, ever-changing formats
what is the duration for the sensory register
each store has a different duration (and capacity) but each is limited
