what is memory
the retention of information over time
episodic memory
ex: last birthday
semantic memory
ex: the largest mountain in Austri
Procedural memory
eX: how to ride a bike
3 systems of memory
sensory memory –> short term memory –> long term memory
how fast in unrehearsed information lost?
15-30 seconds
sensory memory
- these are your senses (iconic or visual, echoic - auditory)
sperling’s test of iconic memory
found that people access to all 12 letters
- unable to recall all letters because memory fades
-
STM stands for
short term memory
Short Term Memory
related to working memory, however not the same
chunking
organizing material into meaningful groups
rehearsal
the rehearsal of information in short term memory
long term memory
life learned facts, experiences, and skills
primary and recency effects
probability of remembering is shaped like a U over time
encoding
active process because we would be overloaded otherwise
- automatic processing vs. effortful processing
(unconscious vs conscious; minimal vs high attention; frequency vs. episodic)
depth of processing refers to
the deeper we process something the mroe likely we are to encode it (looks like, sounds like, means)
maintenance rehearsal
repetition of original stimuli, out loud or mentally
elaborative rehearsal
elaboration by linking them in meaningful ways
- better to connect information rather than repeating it.
memory aids: mneomics
device that enhances recall, so like a long word.
visual imagery
harder to remember abstract words that lack mental images
- 2 forms (verbal and nonverbal)
method of loci
mental palace
what are schemas?
organized knowledge structure or mental models that we have stored in memory
