Module 4: Memory and Cognition Flashcards
What is the three stage model of memory?
info to sensory memory to short term memory (rehearsal) to long term memory (can be retrieved to STM)
What are the three stages of gaining and using memory?
encoding
storage
retrieval
How long can the LTM store information and how much can it store?
indefinite amount of time
seemingly limitless
How is information in LTM expressed?
implicit or explicit (recall or recognition)
What forms is information stored in the LTM in?
procedural (skills + procedures) or declarative (verbalized: semantic (facts) or episodic (events))
What is the duration and capacity of the STM?
20-30 seconds unless actively rehearsed
7+- 2 items unless chunked
What are the four aspects of the working memory?
central executive, phonological loop, episodic buffer, visuo-spatial sketchpad
What is retrograde amnesia?
unable to remember before traumatic brain injury
What is anterograde amnesia?
unable to remember information after brain injury
What is the decay theory of forgetting? Is it the most recent?
memory fades with time
no
What is the interference theory of forgetting?
memory fades because other information interferes with it
proactive: old info affects recall of new
retroactive: new info affects recall of old
What is an encoding failure?
not paying attention, can’t recall
What model does the Ebbinghaus time-course of forgetting curve follow?
logarithmic
What are the 7 sins of memory?
suggestibility (influenced by info to misremember)
misattribution (confuse source of info)
bias (expectations)
transience (clarity affected by time)
persistence (some memories significant, affect others)
blocking (tip of tongue phenomenon)
absentmindedness (encode effectively by attending)
What is the visuo-spatial sketchpad?
briefly stores visual and spatial information
