what is memory
|
the mental process that allows us to acquire, sotre and retrieve information
|
|
The three fundamental processes involved inmemory
______is transferring information into a form that can be entered into and retained by the memory system |
Encoding
|
|
the three fundamental processes involved in memory
_______refers to retaining information in memory so it can be used at a later tme |
storage -- c drive
|
|
the three fundamental processes involved in memory
_______ is how we recover stored information so that we are consciously aware of it. |
retrieval
|
|
the best way to describe memory
|
is using the stage model
|
|
the stage model of memory involves three distinct tages - informatin is transferred from one memory stage to another - each memory stage is throught to difffer in terms of 1.____ or how much information can be stored 2._______or how long the informatin can be stored 3. _______or what is done with the stored information
|
1. capacity
2. duration 3. funciton |
|
stage 1: called ____
takes in a great deal of inforation about the environment) lights, temperture, etc |
sensory memory
|
|
registers a great deal of information from the environemtn and holds it for only a few seconds
|
most sensory memories get downloads what you pay attention to is transferred to the next memory stage
|
|
stage 2: called ____Random Access Memory a doc. on your monitor working on
|
short term memory
|
|
state 3: called ____.
|
lon term memory or brains "c' drive
|
|
informatoin flows back and forth betewwen short - and long term meomory- what is the duratin of sensory memory
|
very short
|
|
what is the duration of visual sensory meoory Iconic memory)
|
1/4 to 1/2 second
|
|
what is the duration of auditory sensory memory (echoic memory)
|
few seconds
|
|
what is the most important function of sensory memory
|
makes the determinantion if we should pass the information on or not to breifly store sensory infermation so it overlaps allows us to perceive the world as continus and unbroken
|
|
Short-Term, Working memory RAM what is the duration of short-term memory
|
about 20-30 secons
|
|
what is maintenance rehearsal?
|
mental or verbal repetition of information
|
|
What happens to information that isn't rehearsed?
|
it quickly fades away
|
|
what is the capacity of short-term memory?
|
about 7 bits of inforatoin plus or minus 2
|
|
what happens whem capacity has been reached?
|
new information bumps out old information
|
|
how can we increase the capacity oif short-term memory
|
chunking or group items together in a meaninful way
|
|
what is the primary function of short term memory
|
provides temporary storage area whil informatin is being transferred from sensory to long term memory
|
|
what is encoding?
|
putting information in to a form that can be retrieved
|
|
use of elaborative rehearsal - to keep things in long term memory
|
focusing on the meaning of the information
|
|
use self-reference effect
|
applying the information to yourself
|
|
sue of visual imagery
|
using vivid visual pictures
|
|
levels of processing framework: shallow vs. deep
|
simple repetiton (maintance rehersal) is a shollow level of processin and more likely to be forgotton. focusing on meaning (elaborative rehearshal) is deeper processing and more likely to be remembered.
|
|
what is the capacity of long-term memory
|
is our brains c drive -- know body has been able to find the limit to long term memory (limitless)
|
|
The thrree major categories of information stored in long-term memory:
1. _______how to perform different skills operations and actions 2. ______memory of specific events or epidoes in your life 3. ______ general knowledge that includes facts, names definitions concepts and ideas |
1. Procedural
2. episodic 3. Semantic |
|
By studing patients with amnesia, we know that long-term memory is composed of two separate but interacting subsymstems and abilities:
|
Explicit (conscious information) memory is memory with conscious awarness
(Corresponds to episodic and semantic memory) |
|
Implicit (nondeclarative) memory is memory ______awareness
|
without conscious
(corresponds to procedural memory.) Procedural is hardest to forget |
|
The Importance of Retrieval cues - what is a retrieval cue
|
a clue, prompt, or hint that helps trigger the recall a stored memory.
|
|
what is retrieval cue failure?
|
the inabillity to recall long-term memories due to missing or inadequate retrieval cues
|
|
The tip-of-the tong (TOT) experience
|
cannot get a bit of information you know is stored
|
|
What do we knowl about memroy from TOT experiences?
|
memroy retrival is not an all or nothing process
|
|
serial position efect has to do with the tip of the tongue what is the serial position effect?
tendency to recall the first items in a list is called________ |
Primary effect
|
|
tendency to recall the final items in a list is called
|
recency effect
|
|
The encoding specificity principle: context effect
|
can remember information more easily when retrieval occurs in the same setting as the original learning.
|
|
Mood congruence
|
A given mood tends to trigger memories consistent with that mood
|
|
Flashbulb Memories
|
Detailed memories surrounding a vivid, rare or significant event
|
|
what is forgetting you forget because you don't use it enough
|
you inability to recall information that was prevoiusly available
|
|
Herman Ebbighaus and the forgetting Curve
|
Used nonsense syallabus to test forgetting. Found that most of our forgetting takes place soon after we originally learn material. the amount of foretting eventually levels off. 1st 20 mins after we are exposed to the information.
|
|
why do we forget? encoding failure -
|
information was never encoded properly for storage in long term memory
|
|
absen mindedness
|
occurs when atteition is divided - your mind isn't on what you're doing.
|
|
prospective memory
|
forgetting to do something in the fure remembering to do something in the futre. Deals with when something needs to be remembered rather than what due to retrival cue faillure this is why we need day planners
|
|
decay theory
|
conscious brain surgery forgetting is due to normal metabolic processes in the brain over time. New memories create memory traces which if not used fade with time.
|
|
Interference theory
|
forgetting is caued by one memory replacing another
|
|
Proactive interference
|
an old memory interefers with remembering a new one
|
|
retroacgive
|
a new memroay interfers with remember an old one
|
|
Motivated forgetting: wanting to forget __________occurs ocnsciously because the person makes a deliberate effort (usually somnething or dramatic)
|
suspression
|
|
__________occurs unconsciously; all memory of an event is blocked from conscious awarness
|
repression
|
|
Memory Construction
|
An active process we construct not just recorded new memories. When we retrieve them we reconsturct them
|
|
Waht is the Misinformation Effect?
|
if you expose some one to false or misleading information. People's existing memories can be altered by exposing them to misleading information.
|
|
Elizabeth loftus classic auto accident study
|
students watched a file of an auto accident. By altering the wording of questions asked later, researchers were able to affect their recall. Memories varied depending on the wording used even through everyone saw the same file
|
|
Source confusion and False memories 1. Source Confusion
|
Can't remember exactly where the memory cam from did it really happen? did i dream it? did I see it on t.v.
|
|
False Memory
|
A distored or fabricated recollection of sojmething that did not actually happen. But, it feels absolutely real.
|
|
What is a schema
|
an original cluser of knowledge and information about particular topics
|
|
what is a script?
|
the typical sequence of actions and behavior of a common evnet
|
|
How can schemas and scripts cause memory distortions
|
by affecting our expetation of what should happen
|
|
The Search for the Memory Trace - Karl Lashley and his research
|
Believed mories were localized or storied in specific area of the brain. Train rats to run a maze but found no speicif location for this memory. Concluded that memories weren't localized but were distributed and stored throughout the brain
|
|
Richard F. Thompson and his research
|
classical conditioned an eye-blink response in rabbits and found this memory was localized in the brain
|
|
who is correct -- Lashley or Thompson?
|
Both memories for simple tasks are localiazed (thomson) memories for complex tasks are distributed through the brain (Lashley)
|
|
The sea snail Aplysia and brai changes involved in memory
|
only 20,000 neurons used classical conditioning to from a memory
|
|
The ______of the neurons is altered. There is an increase in amount of ______produced by the neurons.
|
function / neurotransmitters
|
|
The ______of the neurons also changes. The number of ______ increases.
|
structure / snapses
