Retrieval Flashcards
what is retrerival?
the process of getting information back out of LTM
Process of retrieval
job of retrieval is to use cues to find target memory
cues: pieces of info that are associated with memory
target memory: the thing that you actually want to get back
why does process of retrieval work?
because memories are linked to each other through associations
cat-dog
link to memories in other ways
ex: what did you see yesterday?
Memory research
when we begin to look through our memories we start with cues.
did you see animals yesterday?
search recent memories for animals. animal is associated with squirrel.
-cues can also be other kinds of related content
representation of squirrel like an ornament or sticker
Spreading Activation
given multiple cues we retrieve the other cues to retrieve a complete memory
the memory will be brought back because we thought of all the features. The activation spreads out to other pieces of the memory and eventually if becomes active
- think of other cues of the characteristic squirrel’s sre gray, furry. collect.
retrieving features that were not cued is called pattern completion.
process during and after retrieval monitor whether memories are actually wanted.
You and a friend are talking about your favorite
restaurants. You want to tell her about your favorite
sushi place, so you retrieve all the details from
memory. ______ was the cue for retrieval, and ______
was retrieved through pattern completion.
A. The name of the restaurant; the menu
B. Being a favorite restaurant; the menu
C. Remembering yesterday; a squirrel
D. The menu; being a favorite restaurant
B. Being a favorite restaurant; the menu
What happens when retrieval goes wrong?( 1 & 2)
1) tip of the tongue state- when we know information, but cannot successfully retrieve it.
ex: name of capitol cities
sometimes we say “i know is starts with an A”
2) When recall is influenced by a schema, even when
that schema may not be correct for that situation
Schema: a kind of conceptual organization that can
help us encode and retrieve information
Ex. What’s usually in a restaurant?
sometimes schemas can hurt us when they are incorrect
STUDY: Della Sala et al (1993)
Tested memory for famous faces in people
Tested memory for famous faces in people with
prefrontal cortex damage
faces from different decades. from before brian damage and some after
results: 2 groups of people, people same age did not have damage, people who have the damage
regardless of when the famous face was learned, there was still difficulty retrieving the information because of the prefrontal cortex damage.
Loftus and Palmer (1973)
Watched the same video of a traffic accident
Watched the same video of a traffic accident
answer the question: how fast were the cars going when they ___ each other
got different verbs, “contacted, hit
if we get a low speed verb our estimated of how fast the speed is going.
results: estimated miles per hours based on the word we got from the video, when we are asked the question how fast a car is going we are fishing our features we answer
impacted by the types of phrasing.
Brewer and Treyens (1981)
what typically is found in an office?
what typically is found in an office?
items that are normal and not normal to be in an office.
subjects waited in this office, then asked about what was in the office.
Falsely remembered objects you would expect in an
office, but that weren’t actually there
Due to reconstruction based on a schema of what is
typically in an office
results: reconstructing the office based off of their office schema.
Alisha is looking for a place to get coffee. She
remembers that there is a tea shop nearby, and that
she has seen coffee on the menu there before.
However, when she gets there, they tell her that they
only have tea and never had coffee. What kind of
memory error do you think is occurring?
Incorrect reconstruction based on a schema
A. Incorrect reconstruction based on a schema
B. A source monitoring error
C. Cryptomnesia
D. A tip-of-the-tongue state
A. Incorrect reconstruction based on a schema
or B. A source monitoring error
that she hear somewhere else and she remembered the source incorrectly
Attention
Fernandes and Moscovitch (2000, 2003)
in the same way attention is necessary for encoding , it is also important for retrieval
Main task: recall lists of words that they had heard
previously
Secondary task: make judgments about unrelated
items on a screen
result: doing any secondary task made retrieval more difficult, retrieval requires attention
What makes a good cue? 1
cues should be relevant and meaningful
What makes a good cue? 2
the number of cues, more cues are always more helpful
