order of memory stages
sensory memory
short term memory
working memory
long term memory
sensory memory definition
the perception of sight, hearing, smell, taste, and touch information entering the brain for a short period of time
*retain info long enough for it to be recognized and then passed onto short term memory
sensory memory examples
USES FIVE SENSES- when you watch a movie you don’t notice the gaps that are between frames because each one is held in your sensory storage until the next pops up
short term memory definition
memory that is limited in capacity to about seven items and in duration by the subject’s active rehearsal
short term memory example
repeating words that people just said to you, (them accusing you of not listening)
working memory definition
It is essential for thinking and problem solving. It is described as a mental scratch pad where info that is relevant is stored, and when it is no longer needed it is gotten rid of
working memory example
following multistep directions
parts of working memory
short term memory
executive attention (what stm can access)
long term memory definition
The storage of information over extended periods of time
long term memory types
SEMANTIC |
EPISODIC |
DECLARATIVE |
PROCEDURAL |
semantic memory definition
knowledge of language, including its rules, words, and meanings
semantic memory example
The word jawn means everything in Philly and people from other places might not understand
episodic memory definition

processes of memory
encoding, storage, retrieval
encoding definition
Transforming of information so the nervous system can process it |
storage definition
Process where information is maintained over a period of time |
retrieval definition
Process of obtaining information that has been stored in memory |
how many things can you store in your STM
7+-2 items
primary recency effect
Refers to the fact that we are able to recall information presented at the beginning and end of a list
chunking strategy
taking in information in important groups to make it easier to remember
How long does information in one’s Short Term Memory last without rehearsal?
takes a little less than 20 seconds without rehearsal
