the mechanism we use to create, maintain and retrieve info about the past. learning cannot occur without memory.
flashbulb memory
a clear memory of an emotionally significant moment or event (ex. 9/11)
encoding
put into memory
storage
maintain in memory
retrieval
get info back out of memory
3 Stage model of memory
sensory memory.
short-term memory.
long-term memory.
sensory memory
preserves info in its original sensory form for a brief time, usually only a fraction of a second. allows for the sensation of a visual pattern, sound, or touch to linger for a brief moment after the stimulation is over. transferred into short term memory.
short-term memory
not permanent. retains and processes info up to 30 seconds, holds info long enough for it to be actively worked on or processed by the brain.
long-term memory
memory in which associations among items are stored for a long time. retains info for periods of time beyond the capacity for STM. capacity=unlimited. duration=unlimited. research suggest that you never truly forget anything.
working memory
a limited capacity system for temp storage and manipulation for complex tasks such as comprehension, learning, and reasoning; accounts for dynamic process involved in cognition. any time you need to remember something for a very limited amount of time.
serial position effect
tendency to remember the first and last items better than the rest; remember things because of their POSITION
visual encoding
remembering images and visuals
acoustic encoding
remembering sounds, especially word sounds (ex. it's easier to remember rhymes)
semantic networks
organization of LTM. memory is organizzed based on semantic (meaning) rather than superficial features (what look/sound like).
chunking
organizing items into meaningful, familiar categories; occurs automatically; (it's easier to remember 1492 and 1812 instead of 1,4,9,2,1,8,1,2,)
iconic memory
a photographIC memory lasting for a few tenths of a second; everyone has it; discovered by Sperling
echoic memory
a momentary audio memory of a sound; sounds, words, and ECHOES can be remembered within 3 to 4 seconds, even if attention is elsewhere
amnesia
the loss of memory
recall
ability to retrieve information not in conscious awareness (ex. fill-in-the-blank test)
recognition
ability to identify items previously learned (ex. multiple-choice test)
relearning
a memory measure that assess the amount of time saved when learning material for a second time
blocking
inaccessibility of stored info; may be on the tip of the tongue
proactive interference
Old memories interfere with recall of new
information
retroactive interference
New memories interfere with recall of old information.
misinformation effect
incorporating misleading information into one's memory of an event (ex. How fast were the cars going when they SMASHED into eachother?)
George Miller's Magic #7
a person can typically remember somewhere between 5 and 9 digits on average
elaborative rehearsal
method of transferring material from STM to LTM by making tat info more meaningful in some way, associate new material with familiar meaningful info. why dewald always uses personal stories in lecture.
LTM
declarative memory and procedural memory
declarative memory
things you are aware you are accessing and you can report the contents of that info. episodic and semantic memory
episodic memory
events, self knowing, self remembering, experiences you had that personally involved you
semantic memory
knowledge, facts, not personal, not from a personal experience. info without the experience of when or how we are involved in it.
procedural memory
not knowing through behavior, skill memory, action memoru, hard to link to langauge. ride a bike, tie shoes, type, write
can we trust our memories
NO
constructionist theory
memory is reconstructive process, memories may be distorted, we best remember events and experiences that are consistent with our schemas () and pre-existing expectations
Decay/trace theory
memories gradually fade over time
retrieval theory
forgetting is a result of a failure to to access stored memory
retrograde amnesia
forgetting old stuff
anterograde amnesia
forgetting new stuff
recognition task
recognizing previously encountered events, objects, or people; environmental content is matched to stored memory representations.
primacy effect
In free recall, the tendency to recall the first items on the list more readily than those in the middle.
