Memory Flashcards
What is the Modal Model of Memory?
Sensory memory store - very brief
Short term memory
Long term memory - essentially permanent
What is Sensory memory? What is its capacity, duration and function?
Function: Sustain sensations for identification
Capacity: Very large (“scenic”)
Duration: Very short (3 secs or less)
What is Short-term memory? What is its capacity, duration and function?
Duration: 10-15 seconds without rehearsal
Function: Do conscious work; to think
Capacity: 7 plus or minus 2 items or “chunks”
What is long-term memory? What is its capacity, duration and function?
Capacity: Enormous (unlimited)
Duration: Very long (essentially permanent)
Function: Tie together past and present, prior experience to guide our behavior
Attention
Attention: Selects info from Sensory memory
Rehearsal
Trying to remember & keeps it in working / Short term memory
Encoding
Encoding: How you think about information in short term memory (get into long term memory)
Retrieval
Retrieval: Brings information from long term memory to working memory
What kind of problems did Clive Wearing have?
Musician, no past or future / just a moment to moment consciousness; perceives the world normally, he remembers his wife but not that he has seen her so he has some long term memory about who she is, gets very angry
If something can be lost while something else is perceived it suggests those are two different parts of memory
What type of errors can lead to false memory?
Imagining nonexistent actions or events
Gist-based memories - remembering the general global event vs. specific details
Asking a question vs. a statement
What are heuristics?
Rules of thumb that produce quick results but leave room for errors
Humans use these
What are algorithms?
A procedure that always produces a correct solution
Computer uses these
What is the representativeness heuristic?
occurs when we estimate the probability of an event based on how similar it is to a known situation
What is the availability heuristic?
occurs when we judge the likelihood of an event based on how easily we can recall similar events
What is confirmation bias?
Our tendency to cherry-pick information that confirms our existing beliefs or ideas
