SAFMEDs Chapter 11 Flashcards
Memory
-learning that has continued over time
Information processing model
- general model of memory
- three step process
- receive, rehearsal, retrieval
Rehearsal
- the role of repetition in the retention of memories
- repeating information over and over in order to get the information processed and stored as a memory
Retrieval
-recalling stored memories
Parallel Processing
- dual processing
- interpreting numerous events and stimuli at the same time
- you filter in relevant information and filter out irrelevant information
Multi-store model
- Richard Atkinson and richard Shiffrin
- three stages
- sensory memory, short-term memory, long term memory
- currently accepted model of memory
Sensory memory
- sensory register
- takes a few seconds at most
- processing everything we sense
Iconic memory
-fleeting visual images in sensory memory
Echoic memory
-fleeting auditory signals in sensory memory
Selective or focused attention
-when we voluntarily focus on a portion of our sensory input while ignoring other inputs
Selective hearing
- selective attention auditory edition
- example: not noticing that someone is talking to you because you are watching tv
Cocktail party effect
- hearing your name in a large gathering even if it is spoken across the room
- selective attention
- we are able to filter out nearly everything except what is important to us
Short term memory (STM)
- memory is stored for up to 30 seconds in short term memory (Atkinson and Shiffrin model)
- mental scratch pad
- very sensitive and vulnerable to interruption and interference
Long term memory (LTM)
- final stage
- memory can be stored indefinetly
- dependent on relative importance to the individual
- stimuli must be encoded to form long term memory
- broken into three kinds of memories: episodic, semantic, procedural
Encoding
- taking stimuli from the environment and converting it into a form that the brain can understand and use
- comparing new info to info already learned
- if stimuli are not encoded they will be forgotten
Episodic memories
- the stories of our lives and the experiences we can recall and tell to someone else
- recounting something that happened to you or someone else
- omg last week I went to the store and I ran into…
Semantic memories
- impersonal memories not drawn from personal experience
- common knowledge
- names of colors, names of states, facts
Procedural memories
- memories of how to do something
- how to ride a bike, tie your shoes, bake cookies
Automatic processing
- affects the brain’s ability to handle different stimuli at once
- information processing of well learned activities that occurs unconsciously
- bending your knees and holding the sheet while focusing on moving the patient
Implicit memories
- memories we rretain without conscious effort and often without our awareness
- unconsciously retrieved
- automatic parallel processing
Priming
- using cues to activate hidden memories
- previous stimuli influence how people react to subsequent stimuli
Effortful processing
-encoding that requires attention and conscious effort
Explicit memory
- past knowledge that is consciously brought to mind
- recalling multiplication facts
- you had to make a conscious effort to learn the information
Declarative memory
- explicit memories
- facts we consciously know and can declare
Nondeclarative memory
-implicit memories
Working memory
- short term memory
- limitation of memory it can retain
- limitation of time in which the information can be recalled- ten to twenty seconds
Memory span
-the number of items a person can remeber and repeat back using attention and short term memory
Digit span
-the longest list of numbers that can be remebered and repreated back
George Miller
- magic number 7 plus or minus two
- amount of meaningful information bits one can hold in short-term memory
Chunking
-combining or grouping bits of related information to increase the amount of information stored in STM
