chapter 7: memory Flashcards
the atkinson model
sensory memory, short-term memory, long-term memory
control processes
shift info from one memory to another
encoding
store info to LTM
retrieval
bring info from LTM to STM
sensory memory
holds info for a brief moment of time
echoic
sound memory
iconic
the picture image memory
chunking
spread info apart and organize in small units
mnemonics
improving and assisting memory
hierarchies
organize into broad categories
serial position effect
recall first and last few words. primary and recency
proactive interference
first info learnt occupies memory, leaving no space for recent memories
retroactive interference
recently learnt takes over old memory
phonological loop
storage of working memory that are more numbers and words
visuospatial sketchpad
working memory of visual images
feature binding
mixing picture images into one
episodic buffer
combining images and sounds into story like episodes
central executive
like a traffic cop who directs working memory to coordinate
LTM declarative
semantic: facts in our world
episodic: personal memories (verbalized) explicit
LTM: nondeclarative
procedural: muscle memory
conditioning: classical conditioning (actions) implicit
consolidation
moving STM to LTM in brain
long term potentation
increase connectivity and transmission of neural signal between nerve cells
cellular consolidation
when ltp is longer so make changes more permanent
reconsolidation
hippocampus strengthens, and modify LTM
cross-cortical storage
LTM spread out through cortex of brain
retrograde amnesia
impaired ability to remember events
anterograde amnesia
impaired ability to make new memory
maintenance rehearsal
remembering info by repeating it
elaborative rehearsal
learn by just thinking about the meaning
shallow processing
properties of spelling and sound
deep processing
meaning or function
the schema
clusters of memory that has one’s knowledge about events, objects and ideas
construct memory
recall generalized schema then add specific details
infantile amnesia
inability to remember before age of 3
