Q

The false memory debate

Two sides

A

Therapists position

  • memories are reproductive
  • helping people recover memories allows them to heal

Psychological position

  • memories are reconstructive
  • the recovered memories are likely to be products of the therapeutic process itself

Q

History behind repressed memories

Freud & Psychoanalysis

A

Repressed memories of trauma = present day dysfunction
Finding the ‘cause’ was often thought to alleviate problems
Childhood sexual abuse often thought to be a cause

Many modern day therapeutic treatments rely on ‘recovered memory therapy’, where the primary goal is to uncover repressed, dissociated or otherwise unavailable ‘memories’ of a trauma in order to resolve present day psychological ailments.

Reported adult symptoms of CSA included;
Low self esteem
Poor sleep
Depression
Substance abuse

Q

Goodman 2013

Is it common to forget CSA

A

Conducted a study with 175 women and men who were involved with CSA (141 women).

89% involved with genital contact, 42% penetration

3 phases 1) phone interview 2) postal survey 3) in person interview

Research framed as being about legal experiences and attitudes

  • participants were not specifically asked about the cases they had been involved in
  • the researchers did not disclose their knowledge of the woman’s histories

First phase: 81.1% disclosed the target case
9% denied ever being victimised
Phase 2 & 3: over 90%

Results from the study indicated that forgetting CSA may not be a common experience.

Imply that normal cognitive operations underlie long-term memory for CSA.

Challenge for future research would be to integrate social, cognitive and clinical factors into theories of memory for childhood trauma.

Q

Is it possible to repress memories

Holmes 1995

A

“No controlled laboratory evidence supporting the concept of repression”

No reliable evidence that individuals ‘repress’ or ‘dissociate’ memories of traumatic events.
Minimal evidence for repressed memories raises a serious possibility that the recovered ‘memories’ are false.

Q

DRM paradigm

Roediger & McDermott 1995

A

The Deese-Roediger-McDermott paradigm is a procedure in cognitive psychology used to study false memory in humans

Participants study a list of semantically related words.
When they are later tested, participants often falsely recall non presented critical lures

Q

Lost in mall paradigm

Loftus & Pickrell 1995

A

24 participants received suggestions from siblings of how they got lost in the mall as a child

Results: 6 (25%) participants had “full or partial memory” for the event

Q

Problems with Loftus & Pickrell 1995 study

A

Results do not generalise to childhood memory of sexual abuse

The experience of childhood sexual abuse is a relatively implausible event for most children

In contrast, getting lost is a familiar childhood event that is relatively plausible for most children

  • parental obsession
  • most children have been lost at least once
  • fairy tales

Q

Pezdek, Finger & Hodge 1997

A

20 participants were presented with

1 childhood event
2 false childhood events
- plausible event: Loftus’ lost in mall target event
- implausible event: Received a rectal enema target event

DV: whether each participant recalled information beyond that presented in the description

Plausible event: Loftus’ ‘lost in mall’ paradigm- 3/20 (15%) recalled this event
Implausible event: received a rectal enema - 0/20 recalled this event

Q

Imagination Inflation

A

Is an increase in confidence that a fictional or hypothetical event that was merely imagined was actually experienced

17
Q

Garry 1996, 2001

A

Participants completed a Life Events Inventory (LEI)

  • 60 items each describing a discrete childhood event
  • respondents asked to indicate on a 7 point likert scale how confident they were that the events happened to them before the age of 10

Participants asked to imagine events they had no memory of over a 2 week period

Subjects who imagined the event taking had increased confidence that the event occurred

Why?
Imagining an event makes it more accessible (increases the chance of source monitoring errors)
Might encourage accurate responding

18
Q

Similar ‘imagination’ paradigm

Wade 2000

A

20 participants given 3 interviews over a 2 week period.
About 3 true photographs and 1 false doctored photograph

Doctored photographs elicited about 35% interview 1, to 50% interview 3 false reports

19
Q

Problem with imagination inflation paradigm

A

Is it measuring memories or beliefs? Most study beliefs

Is it safe to assume that autobiographical beliefs are based on memories? Are beliefs and memories meaningfully related.

Is it a problem to us measures of belief to draw conclusions about autobiographical memory

20
Q

Crashing memories paradigm

Crombag 1996

A

193 participants asked “did you see the television film moment the plane hit the apartment building’ YES/NO

107 (55%) claimed to have seen the video footage of the actual crash, yet no actual video footage of the crash exists

21
Q

Crashing memory paradigm

A

Ost (2002): crash of Princess Diana- 44% false reports

Out 2006: explosion in Bali nightclub - 38% false reports

22
Q

Problem with the crashing memory paradigm

A

Are participants truly ‘remembering’ the unseen event?

Pezdek & Lam 2007: “crashing memory” paradigm is used to invested full-blown false memories.
Crombag 1996: …‘apparently these subjects had formed memories’

Ambiguous questions may lead to misinterpretations of the task

23
Q

Smeets 2009

A

“Did you see the amateur film of the Fortuyn shooting?”

Participants were debriefed and asked to answer some questions;
If answered yes then please indicate why you did so;
- unclear which images were referred to by the question
- I tried to complete the questionnaire as accurately as possible and did not want to let the researchers down by stating I could not remember the images
- I really do remember the images of the moment Fortuyn was shot

58% of the participants claimed to remember the unseen footage.
Following debriefing: 10% claimed that they really did remember seeing the images.

When asked the same question again;
10% (6) still answered yes
15% (9) said they were unsure/ could not remember
75% (43) said no

24
Q

Considerations

A

Many of these paradigms use methods similar to those that might be encountered in a therapy session

  • repeated suggestion
  • imagining an suggested event
  • the use of photos
25
Q

Pezdek & Lam 2007

A

Main arguments

  • not all methodologies investigate the same thing.
  • cognitive research should distinguish between different ways in which the term false memory is used
  • concluded that there are several types of false memory
26
Q

Scoboria 2004

A

Individuals rated childhood events for (ie loosing a toy) for:
- general plausibility
- personal plausibility
- autobiographical belief
- memory
- believed frequency of an events occurrence
.
Found that it’s possible to have a belief without a memory

27
Q

Scoboria 2004

Conclusions

A

Plausibility, belief and autobiographical memory are interrelated BUT not the same

Memory implies belief, belief implies plausibility.
Plausibility does not imply belief , belief does not imply memory.

Indicates the importance of directly assessing a construct, rather than using a measure of an alternate construct with which the construct of interest is thought to be correlated.

28
Q

Mazzoni 2001

A

HOWEVER, plausibility and belief are precedents to developing false memory.

Mazzoni proposed a 3 stage process by which false memories can emerge.

1) people must regard the target event as plausible
2) they must come to believe it is likely that they experienced the event
3) they must make a source monitoring error (must mistake their thoughts, feelings and fantasies as genuine memories).

Plausibility can grow into beliefs, which can grow into false memories

29
Q

Freud

A

Freud believed that he could not influence his patients during therapy.

He believed that the pressure was justified because his patients often resisted the idea that they had been abused.

Overcoming such resistance, according to Freud, was crucial to the success of treatment.

30
Q

Survey: Andrews 1999

A

Surveyed 108 therapists who provided all clients with recovered memories over a 39 year period.

In 67% of cases at least one of the following techniques had been used; hypnosis, dream interpretation, guided imagery, use of family photos, relaxation, instructions to remember, interpreting physical symptoms, writing/ art work

In 22% of cases, techniques were used to aid recall before the first memory was recovered.
