77
Q

how we store information depends apon

A

how we store information depends on our interpretation and expectations of the information

78
Q

Schemas

A

an organized knowledge structure or mental model that we have stored in memory
- assists us with interpretation new situations
- helps reduce the amount of information we need to store about common situations/locations/events

79

Q

many memory errors are a failure of

A

retrieval

84

90
Q

Recall testing is demonstrated in which experiement

A

Mantyla (1986)

91
Q

Relearning: Ebbinghaus (1185)

A
  • studied lists of “nonsense syllables”
  • after learning a list, waited a period of time before trying to recall it
  • would the relearn the list until could be repeated without error
  • compaired time it took to learn the list originally to the time it took to learn the list the second time
  • second time always faster. Some memory “saved”. Called it “savings”
92
Q

law of Distributed vs. Massed Practice

A
  • learning material over many short bursts leads to much more effective retrieval than learning in one long session
93
Q

Tip-of-the-Tongue (TOT) Phenomena

A

TOT is the experience of knowing we know something, but cannot get the detail out at the right time
- highlights an eror with retrival

94
Q

does a TOT experience happen is someone who uses sign language

A

yes

95
Q

Encoding specificity

A

is the phenomena where we are more likely to remember information if the when there is a match between conditions at study (encoding) and test (retrieval)

96
Q

What are the 2 main types of encoding specificity

A
  • context dependent learning
  • state dependent learning
97
Q

Context dependent learning is demonstrated in which experiment

A

Godden & Baddeley (1975): the “diving experiment”

98
Q

Context dependent learning

A

shows this context dependent condition also works with auditory noise

99
Q

Context dependent learning

A
  • matching the internal stateat study and test enhances recall
  • very similiar to how matching context between study and test enhances recall
100
Q

Engram

A

104
Q

LTP is prominent is

A

the hippocampal neurons, amygdala, and the neocortex

105
Q

LTP demonstrates

meta memory skills

A
118
Q

what are the three source monitoring errors

A
  • source monitoring confusion
    -“wishful thinking bias
  • crytomnesia
124
Q

Misinformation effect

A

creation of fictitous memories by providing misleading information about an event after it takes place

125
Q

Misinformation effect is demonstrated in which experiment

A

Loftus (1978)
- stop vs. yeild sign experiement
- showed MPI effect

126
Q

Misleading post information makes _____ unrealiable

A

eyewitness testimonies

127
Q

eye witness testimonies are less accurate when

A
  • people observe individuals of a race other than their own
  • talk to other witnesses
  • when the catch only a breif glimpse of the criminal
  • when they view crime under stressful situations (threatened)
  • when there is a gun
128
Q

stradiges to combat problems with eyewitness testimonies

A
  • congnitive interviewing
  • gather witness statements as quickly as possible
  • rely on more reports that are gathered shortly after the event
  • corroborate witness statements with other forms of evidence
129
Q

Cognitive interviewing

a procedure to interview witnesses that is based n what is known about memory retrieval errors
