Q

describe ebbinghaus’s 1885 experiments

A

N = 1 (author) he was only ppt in study, learnt rows of nonsense syllables (consonant-vowel-consonant), after learning he tested his recall over different periods of time

Q

what did ebbinhaus find in his self experiment?

A

most of our forgetting occurs quickly and then continues but at a slower pace. there is less difference in forgetting as time passes

16
Q

decay =

A

forgetting due to the passing of time (theory that time has a causal effect on memory)

17
Q

interference =

A

forgetting due to competition between memories

18
Q

explain Thorndike’s “law of disuse”

A

the more time passes without using a memory, the more the memory decays away until it is entirely forgotten

19
Q

what is McGeoch’s critique of the “law of disuse”

A

the passing of time causes nothing by itself but time is correlated with processes that cause forgetting (such as interference)

20
Q

what are the 2 types of interference?

A

proactive (old memories stop retrieval of new ones) and retroactive (new memories stop retrieval of old ones)

21
Q

what are the 3 types of source monitoring?

A

internal, external, reality

22
Q

what are the 4 types of source information?

A

perceptual, contextual, affective, cognitive

23
Q

what type of source information is higher in detail when actually experienced by the person rather than from other sources?

A

perceptual source information

24
Q

context in which memory was acquired is consistent with an expected source = what source info?

A

contextual source information

25
emotional reaction in context of information =
affective source information
26
mental processing of the information =
cognitive source information
27
give an example of a typical external source monitoring error
misremembering doing something with a particular person
28
what causes a stronger effect for confabulations?
when ppts received confirmatory feedback
29
what were the results from Loftus & Pickrell's false memories experiment?
1/4 of ppts falsely remembered to have been lost in the mall, shows false memories can be implanted via suggestion
30
what were the results for Wade et al's experiment digitally altering photographs to make false evidence?
50% of ppts believed after a week that the hot air balloon event actually happened in their childhood, so 1/2 demonstrated false memories via suggestion. false evidence shown to contribute to formation of false memories
31
what were the results from Zaragoza et al's experiments using a confabulated event?
people who could guess answers to questions were more likely to show false recognition and respond saying 'yes' 1 week later. ppts recalled 20% pf their forced confabulations as their own memories in the free recall at 4-6 weeks
32
deficit in memory caused by brain damage, disease or psychological trauma =
amnesia
33
what is the difference between retrograde and anterograde amnesia?
``` retrograde = loss of ability to access memories PRIOR to the event. anterograde = loss of ability to store new memories AFTER the event. ```
34
what is posthypnotic amnesia (PHA)?
inability to recall events that took place under hypnosis (until presented with a prearranged reversibility cue)
35
PHA is a deficit in which memory process?
retrieval
36
true or false: some people are more susceptible to hypnosis than others
true
37
describe Mendelsohn et al's hypnosis experiment and the results
ppts made to watch a 45 min documentary. 3 conditions: induce PHA, no PHA, simulate PHA ppts then took part in a recognition task. found that PHA resulted in less correct answers than no PHA > suggests hypnosis can induce a state of amnesia that specifically affects retreival
