Dissociation
and the Fragmentary Nature of Traumatic Memories: Overview
and Exploratory Study
Bessel A. van der Kolk and Rita Fisler
Since trauma arises from an inescapable stressful event that
overwhelms people's coping mechanisms, it is uncertain to
what degree the results of laboratory studies of ordinary
events are relevant to the understanding of traumatic memories.
This paper reviews the literature on differences between recollections
of stressful and of traumatic events. It then reviews the
evidence implicating dissociation as the central pathogenic
mechanism that gives rise to posttraumatic stress disorder
(PTSD). A systematic exploratory study of 46 subjects with
PTSD indicated that traumatic memories were retrieved, at
least initially, in the form of dissociated mental imprints
of sensory and affective elements of the traumatic experience:
as visual, olfactory, affective, auditory, and kinesthetic
experiences. Over time, subjects reported the gradual emergence
of a personal narrative that can be properly referred to as
"explicit memory." The implications of these findings
for understanding the nature of traumatic memories are discussed.

Functional
Neuroanatomical Correlates of the Effects of Stress on Memory
J. Douglas Bremner, John H. Krystal, Steven M. Southwick,
and Dennis S. Charney
Recently there has been an increase in interest in the relationship
between stress and memory. Brain regions which are involved
in memory function also effect the stress response. Traumatic
stress results in changes in these brain regions; alterations
in these brain regions in turn may mediate symptoms of posttraumatic
stress disorder (PTSD). Neural mechanisms which are relevant
to the effects of stress on memory, such as fear conditioning,
stress sensitization, and extinction, are reviewed in relation
to their implications for PTSD. Special topics including neural
mechanisms in dissociation, neurobiological approaches to
the validity of childhood memories as they apply to controversies
over the "False Memory Syndrome," and implications
of the effects of stress on memory for psychotherapy, are
also reviewed. The findings discussed in this paper are consistent
with the formulation that stress-induced alterations in brain
regions and systems involved in memory may underlie many of
the symptoms of PTSD, as well as dissociative amnesia, seen
in survivors of traumatic stress.

Say
It Once Again: Effects of Repeated Questions on Children's
Event Recall
Robyn Fivush and April Schwarzmueller
In this paper, we review research examining the influences
of repeated questioning on children's event recall. Issues
addressed include how children's free recall changes across
multiple recounts of the same event, whether responding to
specific questions about an event affects subsequent responses
to those same questions, and whether there are developmental
differences in how children respond to repeated questioning.
Both naturalistic studies of conversational remembering and
more controlled studies using standardized interviews are
discussed. Effects of repeated questioning both within and
across interviews are assessed. In integrating the research
findings, we present a developmental framework for understanding
the effects of repeated questioning that relies on children's
developing memory and narrative skills as well as their social
understanding of the recall context.

Children's
Long-Term Retention of Salient Personal Experiences
Peter A. Ornstein
Research on young children's long-term retention is reviewed
in this article. More specifically, the abilities of 3- to
7-year-olds to remember the details of two types of medical
experiences--a routine physical examination and an invasive
radiological procedure--are discussed in the context of a
framework for considering the flow of information in the developing
memory system. The framework emphasizes four general themes
about memory performance and provides a vehicle for relating
research on memory development to discussions of children's
testimony and adults' abilities to remember early experiences.

Are
Rape Memories Different? A Comparison of Rape, Other Unpleasant,
and Pleasant Memories Among Employed Women
Shannon Tromp, Mary P. Koss, Aurelio Jose Figueredo,
and Melinda Tharan
The study examined empirically-measured memory characteristics,
compared pleasant and unpleasant intense memories as well
as rape and other unpleasant memories, and determined whether
rape memories exhibited significantly more "flashbulb'
characteristics. Data consisted of responses to a mailed survey
of women employees of a medical center (N = 1,037) and a university
(N = 2,142). Pleasant and unpleasant memories were differentiated
by feelings, consequences, and level of unexpectedness. The
most powerful discriminatory of rape from other unpleasant
memories was the degree to which they were less clear and
vivid, contained a less meaningful order, were less well-remembered,
and were less thought and talked about. Few "flashbulb"
characteristics discriminated among memory types. Implications
for clinical work with rape survivors were discussed.

Posttraumatic
Stress Associated with Delayed Recall of Sexual Abuse: A General
Population Study
Diana M. Elliott and John Briere
This study examined delayed recall of childhood sexual abuse
in a stratified random sample of the general population (N
= 505). Of participants who reported a history of sexual abuse,
42% described some period of time when they had less memory
of the abuse than they did at the time of data collection.
No demographic differences were found between subjects with
continuous recall and those who reported delayed recall. However,
delayed recall was associated with the use of threats at the
time of the abuse. Subjects who had recently recalled aspects
of their abuse reported particularly high levels of posttraumatic
symptomatology and self difficulties (as measured by the IES,
SCL, and TSI) at the time of data collection compared to other
subjects.

Recovered
Memories of Abuse in Women with Documented Child Sexual Victimization
Histories
Linda M. Williams
This study provides evidence that some adults who claim to
have recovered memories of sexual abuse recall actual events
that occurred in childhood. One hundred twenty-nine women
with documented histories of sexual victimization in childhood
were interviewed and asked about abuse history. Seventeen
years following the initial report of the abuse, 80 of the
women recalled the victimization. One in 10 women (16% of
those who recalled the abuse) reported that at some time in
the past they had forgotten about the abuse. Those with a
prior period of forgetting--the women with "recovered
memories"--were younger at the time of abuse and were
less likely to have received support from their mothers than
the women who reported that they had always remembered their
victimization. The women who had recovered memories and those
who had always remembered had the same number of discrepancies
when their accounts of the abuse were compared to the reports
from the early 1970's.

Change
in Rape Narratives During Exposure Therapy for Posttraumatic
Stress Disorder
Edna B. Foa, Chris Molnar, and Laurie Cashman
This paper presents a coding system developed to explore changes
in narratives of rape during therapy for posttraumatic stress
disorder (PTSD) involving repeated reliving and recounting
of the trauma. Relationships between narrative categories
hypothesized to be affected by the treatment and treatment
outcome were also examined. As hypothesized, narrative length
increased from pre- to post-treatment, percentage of actions
and dialogue decreased and percentage of thoughts and feelings
increased, particularly thoughts reflecting attempts to organize
the trauma memory. Also as expected, increase in organized
thoughts was correlated negatively with depression. While
indices of fragmentation did not significantly decrease during
therapy, the hypothesized correlation between decrease in
fragmentation and reduction in trauma-related symptoms was
detected.

Factors
Influencing Recall of Childhood Sexual Abuse
Martha L. Rogers
Selective literatures providing perspective on recall of childhood
sexual abuse memories are reviewed. These include known patterns
of autobiographical memories in adulthood, metacognitive mechanisms,
interpersonal influences, and automatic cognitive processing
which can influence judgments and reports of memory recall
in children and adults. Some factors in adult experience such
as mood stated, presence of emotional disorders, past and
current relationships, and participation in psychotherapy
which can influence autobiographical memory and recall of
childhood events are delineated. Available studies directly
exploring recovered memories of childhood abuse are considered
in light of these studies. Finally, some applications to clinical
work and suggestions for future research are outlined.

JTS Adds Pages,Cuts
Publication Cycle Time
The ISTSS Scientific Publications Committee
has taken steps to eliminate the lengthy publication time
for manuscripts accepted for publication in the Journal of
Traumatic Stress (JTS).
The problem developed following publication of the special
issue on traumatic memory research in October 1995 and two
special sections (on trauma and society, and on transportation
disasters) in April and July of 1995.
In addition, there has been an impressive improvement in the
quality of manuscript submissions in general. JTS' publication
time was discussed at the ISTSS Board meeting in November,
and the Board agreed that this situation needed to be remedied
in order to maintain high quality submissions.
Based on this initiative, the Executive Committee authorized
additional pages to be published in the 1996 volume (Volume
9) to "catch up." These additional pages will completely
alleviate the manuscript backlog, so that articles now being
submitted to JTS will not be affected by the delay. Total
time from acceptance to publication will be back to the standard
of 8-9 months, continuing the Society's obligation to Plenum
Publishing to submit manuscripts at least five months ahead
of the publication date.
In addition, steps are being taken so that we do not experience
delays in the future:
- The length of regular articles will be limited to 7,500
words, including references and tables (about 26 pages with
generous margins and a 12-point font).
- The suggested page count will be changed to a suggested
word count to make lengths of submissions more comparable.
- Brief reports will be limited to 2,500 words.
- Commentaries will be limited to 1,000 words.
As previously reported, the rejection rate
for JTS has continued to increase, and more brief reports
are being published. These various changes ensure that JTS
will stay on a reasonable publication schedule, and that the
quality of manuscripts will continue to be high. These new
guidelines will appear in the January 1996 issue. The Scientific
Publications Committee is working with Plenum to ensure that
the format for future issues will sufficiently meet the Society's
space needs.
While limited space has been a problem in the past two years,
ISTSS is fortunate to have this problem in a time of proliferation
of professional journals, when many other publications are
having difficulty filling their allotted space.
