Q

what do release from PI experiments tell us about the way words are stored in LTS

A

the similarity that matters in recall from LTS is semantic, therefore, words are stored in LTS in terms of their meaning

Q

describe the Minami & Dallenbach (1946) Cockroach Experiment

A

cockroaches were conditioned to run towards light, then were separated into normal activity or sensory deprivation groups. after certain time intervals, the sensory deprivation cockroaches had 100% recall and the normal activity cockroaches forgot

Q

After viewing pictures of a car going through a stop sign, subjects are asked misleading questions about a car going through a yield sign. Then and given a forced choice recognition test. They must choose between the original stop sign pic and a new one with a yield sign. 80% choose wrong. what experiment is this and what is it testing?

A

Loftus & loftus (1980); whether everything is permanently in our minds and just not always accessible, or if when it is forgot it is really no longer there

Q

Loftus’s interpretation of the results in which subjects asked the misleading question thought there was a yield sign instead of a stop sign was that…

A

Q

What is the main problem with Loftus’s experiment?

A

It does not prove that old memory is GONE, just that it was not retrieved

Q

How did McCloskey & Zaragoza’s experiment differ from Loftus’s?

A

half the subjects are asked if it was a hammer or a wrench after being mislead or not. The mislead group and the control group performed about the same on the modified procedure

25
skills, memory of how to do something
procedural memory
26
memory that stores meaning and can be told
Declarative or Propositional Memory
27
the study of meaning
semantics
28
a basic idea, a unit of meaning just large enough to be true or false. Concepts and relations between them
proposition
29
Methods of studying semantics include (3)
linguistics, artificial intelligence, and experimental psychology
30
What is the Cognitive Economy Question
which propositions do you store directly and which do you infer?
31
answer to the cognitive economy question that states that everything is stored separately
non-economical storage
32
answer to the cognitive economy question that says we only store what is necessary. If you can infer something from what is already stored, you don't store it
Economical storage
33
Conrad's shark experiment showed that...
cognitive economy does not occur for frequently associated properties
34
What happened in Conrad's shark experiment?
an AI experiment where the association between "shark" and "teeth" should have taken longer to connect, but took less time because they are commonly paired
35
things remembered due to a study episode EVEN THOUGH YOU ARE NOT TRYING TO REMEMBER THE ITEMS
implicit memory
36
your ability to INTENTIONALLY remember items from a study episode
explicit memory
37
The inability to remember where existing knowledge was acquired.
source amnesia
38
Experiment that addressed how levels of processing affect explicit or implicit memory.
Graf & Mandler levels of processing experiment
39
sachs story (meaning vs form) experiment, what parts of the story did the subjects notice and what did they forget?
Subjects forgot the form of the sentence, but remembered the meaning. Subjects noticed semantic changes only
40
In ____, you remember the actual words of the sentence; in _____ you remember the meaning but forget the wording
STS; LTS
41
the idea that propositions that contain the same concepts connect together in memory
integration hypothesis
42
An implicit memory effect in which exposure to one stimulus influences a response to another stimulus
priming
43
the idea that memory is organized by propositions
proposition hypothesis
44
A method of finding what part of the episode subjects remembered and what they forgot where an incorrect observation by the subject is present when the signal is in fact absent. In Sachs (1967) this was used by showing sentences with the same meaning but different wording
false alarm method
45
After the outcome is already known and passed, this is the tendency to believe that you knew what the outcome would be all along
Hindsight bias
46
In Graf & Mandler 1984, Subjects studied words and either rated "liking" them (deep) or counting syllables (shallow). Then they were given a stem completion test to measure implicit memory, and a cued recall test to measure explicit memory. What were the results of this experiment?
Processing level has no effect on implicit memory, but deep processing leads to better explicit memory
47
What is believed to cause source amnesia
a disconnect between semantic and episodic memory
48
what was the surprising result of the thorn hypnosis experiment
subjects retained information they learned while hypnotized, even though they could not remember learning it
49
collis & quillian canary experiment tested subject's response times to true or false statements about canaries. Why?
to attempt to map out how propositions are stored in the network model
50
What event suggests that old memories are not gone when they are forgotten
spontaneous recovery of memories
51
test of memory where subjects are presented with a list of words, then later are given a list of the first three letters of those words and must complete them
stem completion task
52
Weldon & Roediger visual and audio words experiment found that
subjects remembered words better when they had been primed with written words than when they had been primed with auditory and picture stimuli
53
propositions that follow from the directly-stated propositions but were not directly stated themselves.
inferences
54
logical inferences
Inferences that necessarily follow from directly-stated propositions
55
pragmatic inferences
inferences that are probably but not necessarily true
56
Way of measuring how closely propositions are connected together in web
response time
57
In McKoon & Rattcliff, subjects were read a series of propositions and measure subject's response times to see what words prime for others better. their results supported _______ hypothesis
integration
58
What event suggests that old memories are not gone when they are forgotten
spontaneous recovery of memories
59
test of memory where subjects are presented with a list of words, then later are given a list of the first three letters of those words and must complete them
stem completion task
60
Propositions that link concepts in a text to concepts in a schema
schema instantiation inferences
61
propositions that follow from the directly-stated propositions but were not directly stated themselves.
inferences
62
logical inferences
Inferences that necessarily follow from directly-stated propositions
63
pragmatic inferences
inferences that are probably but not necessarily true
64
Way of measuring how closely propositions are connected together in web
response time
65
In McKoon & Rattcliff, subjects were read a series of propositions and measure subject's response times to see what words prime for others better. their results supported _______ hypothesis
integration
66
An organized set of propositions that describes the general characteristics of some thing or activity
schema
67
schemas are stored in
semantic memory
68
Propositions that link concepts in a text to concepts in a schema
schema instantiation inferences
69
basic strategy for mnemonic devices include (3)
1. make each item distinctive (reduce interference) 2. make a collection of items meaninguflly related (instantiate a schema) 3. use a retrieval strategy to make sure you don't miss anything
70
a serial recall strategy in which peg words are used to remember things word for word. S's version of this was to mentally walk down a street and use cues on that street as peg words
Method of Loci
71
V.P (studied by hunt & love) used ___________ to recall a continuous paired associate task of 3 random letters paired with words
rapidly generated semantic associations
