Title: Betrayal Trauma and Memory


1
Betrayal Trauma and Memory
  • The Link between
  • repression and recovery of memories and life
    threatening betrayal

2
Background - Sexual Abuse
  • Historically, reported statistics varied
  • Kinsey (1953)
  • 1 in 4 women reported childhood sexual abuse
  • Weinberg (1955)
  • 1 to 2 cases of incest per year, per each million
    U.S. citizens
  • Finkelhor (1975)
  • 19 females and 9 males
  • Henderson (1975)
  • 1.1 to 1.9 per million people
  • Timnick (1985)
  • 27 females, 16 males
  • Russel (1986)
  • 16 of females were were sexually abused prior to
    18 years old
  • Pope and Hudson (1995)
  • 10 of women and 5 of men endured serious
    childhood abuse. (14 million adults in the US)

3
Background Lost and Recovered Memory
  • Disparity between clinical practitioners and
    laboratory/cognitive scientists regarding memory.
  • Clinicians reporting loss and then recovery of
    traumatic memories
  • Pierre Janet (1889), Breuer and Freud (1893),
  • WW I - Meyers (1915), Southard (1919)
  • WW II Sargant and Slater (1941)
  • Vietnam War van der Kolk, 1987

4
Background Lost and Recovered Memory
  • False Memory Syndrome
  • 1980s Day-Care Abuse Hysteria
  • Kern County, McMartin, Wee Care
  • ReligiousTolerance.org
  • Lawrence Wright The New Yorker, 1993
  • Remembering Satan
  • Ingram case (Olympia)
  • Confession followed by recantation by accused
    perpetrator
  • Presented as modern day Salem Witch Trial
  • Wright inferred that he had documented 1000s of
    cases of cases of false accusations.
  • In Ethics on Trial Trash and Flash Threaten to
    Corrupt the American Media,Judith Herman noted
    that when confronted, Wright answered that he had
    only documented one case.
  • The Facade of Scientific Documentation
  • Many cognitive scientists also rejected concept
    of delayed recall or accuracy of retrieved
    memories. They had not experienced it in
    laboratory conditions.
  • Link to Elizabeth Loftus article, 1995

5
Background Lost and Recovered Memory
  • In 1990s Cognitive Scientists start to take
    Recovered Memory seriously
  • Freyd, in 1996, published Betrayal Trauma
  • Airline near-collision story
  • Clarified/standardized terminology and techniques
  • Utilized and expanded latest knowledge related to
    memory
  • Eliminated diminutive terminology when referring
    to victims
  • Mechanic, Resnick and Griffen in 1998 studied
    memory in 92 rape victims
  • Within 2 weeks following rape 37 of the subjects
    experienced significant amnesia
  • At 3 months only 16 of the completing subjects
    had significant amnesia
  • Conclusions
  • Following rape there is a high incidence of
    recovered memory
  • Amnesia and recovered memory occur more often in
    response to victimization by known perpetrators
  • Dissociation, but not ordinary memory processes
    like forgetting seems to play a primary role in
    the encoding, storage and retrieval of traumatic
    memories

Betrayal Tauma
  • Addresses both How and Why we forget traumatic
    experiences.
  • How
  • Narrative memory bypassed
  • When recalled, majority of subjects report that
    they initially experienced their memories as
    sensations and affects
  • Why (Think, survival!)
  • Normal trauma (remembered)
  • Important to remember the event, so as not to
    repeat it
  • Betrayal Trauma (not remembered)
  • Two dimensional model
  • Terror and threats to life bodily harm
  • Betrayal and threats to social survival
  • Childhood sexual abuse is more likely to be
    forgotten if it is perpetrated by a parent or
    trusted caregiver in order for the victim to
    preserve the attachment.

Freyd's Two-Dimensional Model for Traumatic
Events
10
Understanding Mechanisms - How
  • Traditional model of memory
  • Conceptualized as a thing
  • Looks at memory as coherent, single, system
  • Encoding, storing, retrieval
  • A more recent view of memory
  • A component of a multitude of other systems
  • Brain is multifaceted
  • For each type of learning there is associated
    memory
  • PET scans provide evidence that information
    stored in memory is linked to related mental
    mechanisms
  • Object Knowledge, Multiple modules processing
    events in parallel
  • Roe and Schwartz (1996)
  • 60 of their abused inpatients reported their
    first recovered memory of abuse as somatosensory
    flashback.

In Summary
  • Freyd
  • Abuse and interpersonal victimization is a
    staggering problem
  • Some people forget the abuse
  • Forgetting is more likely when the perpetrator
    was a care giver
  • Memory accuracy is separate from memory
    persistence
  • People have unscientific and biased ideas about
    these issues

17
In Summary
  • Freyd
  • What needs to change?
  • We need to stop confusing the persistence of a
    memory with its accuracy because there is no
    compelling evidence that a memory is more or less
    accurate if it is continuous compared with
    recovered
  • There is evidence that memories are more likely
    to be forgotten if the perpetrator is a care
    giver
