memory Flashcards
encoding
the way that info is processed in our brain in order to get stored
visual encoding
storing memory as a picture that we can view later
acoustic encoding
storing sounds in our memory
semantic encoding
storing the meaning of an event
ATKINSON AND SHIFFRIN MULTISTORE MODEL
sensory memory is initial visual/audio stimuli being quickly recorded for a few seconds in order to prevent processing overload
short term memory lasts for longer than sensory but gets forgotten if not rehearsed
long term memory is the result of rehearsal and lasts much longer
BRADDELY AND HITCH’S WORKING MEMORY MODEL
the idea that STM has many subsystems, but most notably:
Central Exec. - acts as attention sensory store, it channels info to 3 component processes:
visuo-spatial sketchpad: deals with visual and spatial info eg calculating distances
phonological/articulatory loop: memorisation of words by recital in continuous loop (called articulatory process)
multimodal episodic buffer: puts all sensory info into chronological order/stories
CRAIK AND LOCKHART’S LVLS OF PROCESSING MODEL
suggests that the depth at which we process info affects its place in LTM
Elaborate Semantic Processing: processing can be shallow or deep - if we look at sensory info visually, it is shallow, if we look at it audibly, its deeper, if we really think about the semantic meaning of the information, we engage more with the info, and hence it is deepest.
DECLARATIVE MEMORY
requires conscious recall, concerns info that is explicitly stored and retrieved (eg knowledge for an exam)
can be subdivided into semantic, episodic, and autobiographical memory
PROCEDURAL MEMORY
focuses on implicit learning of motor skills eg riding a bike and swimming
proactive interference
occurs when what we already know contradicts what we are learning - old memories disrupt new ones
retroactive interference
occurs when later learning interferes with what we already know - new memories disrupt old ones
EBBINGHAUS FORGETTING CURVE
shows the relationship between forgetting and time using an experiment with NONSENSE SYLLABLES
things that affect memory
smells
emotion
stress
false memory syndrome
when a false memory causes big harm to an individual’s quality of life
false memory
when we remember things that didnt actually happen
