Q

Eileen Franklin-Lipsker Case Study

A

-Eileen Franklin-Lipsker dobbed in her father (George Franklin) for her friend’s murder (Susan Nanson, age 8) 20 years after the event.
-She had no memory of the event until then, which came flooding back to her after therapy that used hypnosis/guided imagery techniques.
-Her memory matched things about the case, but importantly all the details recalled by Eileen had been publicized by the media.
-Elizabeth Loftus went to stand to talk about the misinformation effect/ the fact that memory can be distorted. The jury did not believe her that an individual could have a false memory for an entire event.
-George Franklin was convicted, but eventually, the conviction was overturned because you can’t use evidence recovered by hypnosis in California law cases.
-Additionally, Eileen accused George of another murder that he could not have ever committed (had an alibi) and so that called into question her reliability as a witness.

Q

Why can’t use use hypnosis as evidence by California law- what makes it different to normal interviewing techniques?

A

It’s a lot more speculative than just interviewing about the case

Q

The Notion of Repression

A

-The notion of repression was introduced by Sigmund Freud.
-Traumatic events are banished from conscious recall until we are able to cope with them.
-Emotion seeps into everyday life.
-When uncovered, memories are in pristine condition (not subject to normal processes of decay)

Q

Self-Help Books

A

-Encouraged those with no memory to dig deeper and almost ‘look’ for abuse

-Pushed the narrative that abuse is really common and that you may just not recall it. Lead to an increase in people with a range of issues in their life wondering if they had been abused in the past

-Examples of statement from self help books “If you think you were abused, and your life shows the symptoms, then you were.”

Q

“Symptom” Lists

A
  • Depressive symptoms
  • Feeling anxious
  • Being scared or having phobias
  • Sexual difficulties
  • Sense of failure or helplessness

These lists have been critiqued because they are an “all-purpose female checklist” (Carol Tavris, 1993). In other words most people have these ‘symptoms’ to some degree- it does not mean they were abused necessarily!

Q

Dangerous Therapy

A

Therapy can result in false memories of traumatic events, including abuse, due to the use of techniques that encourage patients to “remember” past events that may not have occurred.

Q

Plausibility-enhancing Evidence

A

Q

How does this quote illustrate dangerous therapy techniques:
“I kept trying to talk about the things that were painful in my life and she kept saying that there was something else.”

A

This quote illustrates how a therapist’s a priori assumptions can influence the course of therapy, potentially leading the patient to “remember” traumatic events that did not actually occur.

Q

How does this quote illustrate dangerous therapy techniques:
“For the past 2 years, I’ve done little else but try and remember.”

A

his quote demonstrates the potential dangers of therapy, as patients may become fixated on trying to remember past traumatic events that may not have actually occurred, potentially leading to psychological harm.

Q

Memory Wars
“This is not [only] an intellectual war, but a war that is being fought in the media, the courtroom, and in legislative chambers” Bloom (1995)

A

-A term used to describe the controversy surrounding the reliability of recovered memories of childhood sexual abuse.
-This issue was not only debated in academic and scientific circles but also became a public matter, with a significant impact on the media, the courtroom, and the legislative chambers.
-As Bloom (1995) suggests, this was not just an intellectual debate, but a real “war” with significant social and legal implications.
-The memory wars pitted therapists, patients, and advocates of the recovered memory movement against skeptics, critics, and opponents who questioned the validity and accuracy of such memories.

Q

Retrospective Studies

A
  • Individuals are interviewed today
  • Asked about history of abuse
  • Asked about the memory continuity
18
Q

Prospective Studies

A

-Individuals with a documented history of abuse (it is known they were abused)
- Interviewed many years later

My understanding is that prospective studies involve planning ahead from the time of abuse. i.e. we know this child has been abused, lets interview them years later.

19
Q

Case Studies

A
  • Individual cases or groups of cases presented alongside interpretation of repression from therapist or researcher
    -Can be retrospective or prospective
20
Q

Williams (1994)

A

-Women with documented records of sexual abuse between the ages of 10 months and 12 years
-Interviewed around 17 years later
-38% did not mention the abuse
-Interpreted as evidence for repression
-Many of the abusive events occurred during a period characterized by childhood amnesia
-Repression is not the only reason that someone wouldn’t report abuse in an interview
-Participants were never directly asked about the documented event
-Participants reported abusive events outside of the documented event

21
Q

Summary of findings for evidence for recovered memories…

A

-To date, there is no good evidence to support the repression and recovery of traumatic memories
-Evidence does not suggest anything beyond ordinary forgetting and remembering
-Methodological concerns are rife in the existing repressed memory literature

22
Q

Some recovered memories have been shown to be impossible:

A
  • psychologically (e.g. children recalling things from they were 6 months- that is not possible as falls
    under the childhood amnesia period)
  • biologically (e.g. broken bones, scars would be present if the memory was ‘true’)
  • geographically
  • factually (the person they accused wasn’t present)

These memories still involve a burden of proof in that despite the events not being possible the memory is very real for the person.

23
Q

“Retractors” as evidence for false memories…

A

-Hundreds of individuals that recovered memories of abuse eventually retracted their allegations
-Many have sued their therapists
-Retractors have enabled psychologists to gain insight into the processes by which the memories were uncovered
-Retractions seemed primarily based on qualities of the memories (e.g. too detailed or too vague to be plausible)

24
Q

Laboratory research as evidence for false memories…

A

A vast body of research has shown that memories for non-experienced events can be relatively easily implanted

25
Q

The false narrative paradigm: Loftus & Pickrell (1995)

A

-Interviewed about 4 childhood events
-Three events were true, supplied by family members
-One was false (being lost in a mall)
-Three interviews, spaced up to three weeks apart
-Guided imagery instructions (e.g. imagine yourself back at the place- what do you see… Note: guided imagery often classed as a questionable interview technique)
-25% remembered and described the false event at the end of the three interviews

26
Q

Recipe for a Recovered Memory after suggestion has occurred…

A

Step 1 – considering the false event to be personally plausible

Step 2 – developing a belief that the memory happened

Step 3 – constructing a memory (e.g., an image or narrative)

Step 4 – making a source monitoring error (source confusion)

27
Q

Plausibility and Script Knowledge : Pezdek, Finger & Hodge (1997)

A

-Gave Jewish and Catholic students written narratives of true and false events from their childhoods

-Jewish students were more likely to form a false memory of taking part in a Jewish ritual than a Catholic ritual

-Catholic students show the opposite trend

-Also measured relative ease of planting a memory for a plausible event (being lost in a mall) versus a less plausible event (being given an enema: would not know what would happen)

-All of the false memories created were for the plausible event

28
Q

Is script knowledge and plausibility fixed?

A

Plausibility can be increased experimentally: for example you could provide knowledge to participants about what would happen in a given event (altering script knowledge)

i.e. you increase script knowledge before hand when you attempt to implant a false memory later on it will seem more plausible to the individual making it more likely it becomes their own memory

29
Q

Braun, Ellis, & Loftus (2002). Study showing implanting of a false memory via media.

A

-Participants viewed an ad for Disney showing Mickey Mouse
-Relative to controls, participants’ confidence that they had shaken hands with Mickey Mouse at a Disney resort increased
-Different participants viewed an ad for Disney showing Bugs Bunny
-Relative to controls, participants’ confidence that they had shaken hands with Bugs Bunny at a Disney
resort increased
-Why is the Bugs Bunny experiment more compelling? Bugs Bunny is not a Disney character and so individuals could never have shook hands with him. Therefore, it eliminates the possibility the individuals could be remembering an event that did actually happen to them in the past.

30
Q

Wade et al. (2002). Implanting false memories for events through the use of media- photos

A

-Undergraduate participants
-Obtained photos from sibling
-Doctored 1 photo
-Asked participants to recall events in 4 photos over 3 interviews
-Over 50% of participants formed a partial or complete memory for the hot air balloon ride

31
Q

In Wade et al. (2002) is this quote an example of a partial or complete memory?

“I feel sort of like my mind’s playing tricks on me. I sort of think I remember being up in it. But I don’t know if that’s just me thinking I might have been. I can see the road and people and a big paddock.”

A

This is a partial memory

32
Q

In Wade et al. (2002) is this quote an example of a partial or complete memory?

“… it happened in Form 1 at the local school there. Basically, for $10 or something you could go up in a hot air balloon and go up about 20 odd metres. It would have been a Saturday and we went with, yeah, my parents, and, no, not my grandmother. I’m pretty certain that it’s Mum on the ground taking the photo.”

A

This is a complete memory

33
Q

Lindsay et al. (2004)

A

-Half of participants took part in standard false narrative paradigm

“I remember when Jane was in grade 1, and like all kids back then, Jane had one of those revolting Slime toys that kids used to play with. I remember her telling me one day that she had taken the Slime to school and slid it into the teacher’s desk before she arrived. Jane claimed it wasn’t her idea and that her friend decided they should do it. I think the teacher, Mrs. Smollett, wasn’t very happy and made Jane and the friend sit with their arms folded and legs crossed, facing a wall for the next half
hour.”

-Remaining half were given a school photo as an additional cue ( as well as the false narrative)

-78% of those in the “photo + narrative” condition formed a false memory, compared to 45% in the “narrative only” condition.

34
Q

Garry et al. (1996) and imagination

A

-Participants rated 40 childhood events on a scale ranging from 1 (definitely didn’t happen) to 8 (definitely happened)
-2 weeks later, participants were asked to imagine some of the events occurring
-Participants were then asked to complete the rating form again
-Imagining an event occurring led to a significant increase in confidence that it occurred
-“Imagination Inflation”

35
Q

How do we know that participants actually believe the false memories that have been formed?

A
  1. They are genuinely surprised when debriefed
  2. They are willing to say that they are making something up
  3. They were happy to report that they didn’t remember the true events
  4. They came up with reasons for not being able to remember
36
Q

Alien Abduction Memories

A

-Claims of abduction by space aliens are becoming increasingly common

Narrative accounts of these abductions are often strikingly similar:
– visiting spaceships
– intercourse with aliens
– medical probes
– extraction of sperm/ova

37
Q

How could false memories be used as a treatment for addictions or as a weight loss strategy?

A

-People who form false memories for bad reactions to alcohol or foods will be adverse to having that food later on

-Could you deliberately therefore implant memories of unhealthy/ fatty foods so that individuals avoid them? (do they same sort of thing for drugs)

38
Q

Clancy et al. (2002)

A

Broadly investigating whether certain individuals are more prone to false memories than others

-Three groups of participants:
Recovered memory condition
Repressed memory condition
Control

-Each participant was presented with 20 DRM trials – each list either had 3, 6, 9, 12, or 15 words.

-After hearing each list, participants completed a distractor task before being asked to recall as many words as possible

  • Those who claimed to have recovered or repressed memories of alien abduction were more prone to falsely recall items from the list (critical lure)

-Note: upward slant expected in lines for all three conditions as when the number of words in the list gets greater recall is worse but the lines for the repressed and recovered conditions are shifted upwards compared to controls

-False recall was related to depressive symptomatology, absorption, magical ideation, and dissociative experiences (mind wandering)

-Similar findings have been observed for women who report recovered memories of sexual abuse (but controversial to keep going with this research)

39
Q

What is the DRM procedure?

A

-DRM procedure: give list of words that are all linked to one word that it not there

-This word is known by psychologists as the critical lure

-Most people likely to include the critical lure in their recall

-Is a quick lab procedure to show false memories

(in lecture we did a list related to sleep but the topic could be anything)

41
Q

McNally et al. (2004)

A

People with Post Traumatic Stress Disorder exhibit several distinct physiological reactions when recounting their traumatic experiences:
-increased heart rate
-tension in facial muscles
-increased skin conductance

How do people with false traumatic memories react when recounting these episodes? Do they have the same physiological responses as those with real trauma?

McNally et al. (2004) had both a control participant and “abductee” listen to an abduction script and they were then tested for physiological responses. 60% of “abductees” showed physiological signs consistent with PTSD. (controls had no response whatsoever so wasn’t just that hearing a distressing script caused physiological symptoms)

42
Q

Overall conclusions

A

-Research to date does not support the notion that traumatic memories can be repressed and then uncovered at a later date

-False memory research provides a far more parsimonious explanation for recovered memories

-Unfortunately, at this stage, we cannot tell the difference between real and false memories
