Strand² Squared LLC currently only endorses Certified FETI as a “trauma Informed” interview methodology. We are working diligently to review research on other methodologies and practices to continue to improve our collective response to individuals who have experienced high stress and trauma.
The vast majority of current interview techniques and protocols pre-date our current understanding of neuroscience, the impact of high stress and traumas effect on memory.
Most interview techniques and protocols require a narrative in a sequential or logical way. There is also a heavy reliance on “Who”, “What”, “When”, “Where” type questions. We also believe there is a misunderstanding by many professionals that “being nice” or by having a focus primarily on open-ended questions will make the response “trauma informed”. Being nice and utilization of open-ended questions are a good start but do not fully qualify the approach as trauma informed.
We are very interested in doing the right thing and using methodologies that are best for professionals responding to people who have experienced high stress and trauma. If you have an interview technique or protocol that is both rooted in neuroscience and trauma informed – we would like to hear about it!
There is a lot of research to support our work, this is only the tip of the iceberg.

Shifting visual perspective during memory retrieval reduces the accuracy of subsequent memories by Petra Marcotti and Peggy L. St. Jacques
Memories for events can be retrieved from visual perspectives that were never experienced, reflecting the dynamic and reconstructive nature of memories. Characteristics of memories can be altered when shifting from an own eyes perspective, the way most events are initially experienced, to an observer perspective, in which one sees oneself in the memory. Moreover, recent evidence has linked these retrieval-related effects of visual perspective to subsequent changes in memories. Here we examine how shifting visual perspective influences the accuracy of subsequent memories for complex events encoded in the lab. Participants performed a series of mini-events that were experienced from their own eyes, and were later asked to retrieve memories for these events while maintaining the own eyes perspective or shifting to an alternative observer perspective. We then examined how shifting perspective during retrieval modified memories by influencing the accuracy of recall on a final memory test. Across two experiments, we found that shifting visual perspective reduced the accuracy of subsequent memories and that reductions in vividness when shifting visual perspective during retrieval predicted these changes in the accuracy of memories. Our findings suggest that shifting from an own eyes to an observer perspective influences the accuracy of longterm memories.
Stress Signalling Pathways That Impair Prefrontal Cortex Structure and Function by Amy F. T. Arnsten
The prefrontal cortex (PFC) — the most evolved brain region — subserves our highest-order cognitive abilities. However, it is also the brain region that is most sensitive to the detrimental effects of stress exposure. Even quite mild acute uncontrollable stress can cause a rapid and dramatic loss of prefrontal cognitive abilities, and more prolonged stress exposure causes architectural changes in prefrontal dendrites. Recent research has begun to reveal the intracellular signalling pathways that mediate the effects of stress on the PFC. This research has provided clues as to why genetic or environmental insults that disinhibit stress signalling pathways can lead to symptoms of profound prefrontal cortical dysfunction in mental illness.
The Psychological Impact of Rape Victims’ Experiences With the Legal, Medical, and Mental Health Systems by Rebecca Campbell Michigan State University
This review article examines rape victims’ experiences seeking postassault assistance from the legal, medical, and mental health systems and how those interactions impact their psychological well-being.
Childhood Trauma, the Neurobiology of Adaptation, and “Use-dependent” Development of the Brain: How “States” Become “Traits” by Dr. Bruce Perry et al The impact of traumatic experiences on the development and function of the brain are discussed in context of basic principles of neurodevelopment. There are various adaptive mental and physical responses to trauma, including physiological hyperarousal and dissociation.
The Temporal Dynamics Model of Emotional Memory Processing: A Synthesis on the Neurobiological Basis of Stress-Induced Amnesia, Flashbulb and Traumatic Memories, and the Yerkes-Dodson Law by David M. Diamond, et al A review of research on the effects of stress on LTP in the hippocampus, amygdala and prefrontal cortex (PFC) and present new findings which provide insight into how the attention and memory-related functions of these structures are influenced by strong emotionality.
Human emotion and memory: interactions of the amygdala and hippocampal complex by Elizabeth A. Phelps
The amygdala and hippocampal complex, two medial temporal lobe structures, are linked to two independent memory systems, each with unique characteristic functions. In emotional situations, these two systems interact in subtle but important ways.
The Neurological Basis of Anxiety of Fear: Circuits, Mechanisms, and Neurochemical Reactions (Part 1) by Dennis S. Charney, et al
This review seeks to highlight how specific neuronal circuits, neural mechanisms, and neuromodulators may play a critical role in anxiety and fear states.
Trauma and Memory by Bessel A. van der Kolk, MD
The present paper reviews the literature on traumatic memories and discusses the recent neuroimaging studies which seem to clarify the neurobiological underpinnings of the differences between ordinary and traumatic memories.
Translational Challenges With Tonic Immobility
by Lori A. Zoellner
Drawing heavily from the nonhuman animal literature, understanding of tonic immobility (TI), a sustained and involuntary physical immobility, may yield clear clinical implications and strong future translational research.
Exploring the Nature of Traumatic Memory: Combining Clinical Knowledge
with Laboratory Methods by Bessel A. van der Kolk, James W. Hopper Janet E. Osterman
We assessed changes in traumatic memory characteristics over time and differences between memories of subjects with and without current Posttraumatic Stress Disorder.
Why Rape and Trauma Survivors Have Fragmented and Incomplete Memories by James Hopper and David Lisak
In the midst of assault, the brain’s fear circuitry takes over while other key parts are impaired or even effectively shut down. This is the brain reacting to a life threatening situation just the way it is supposed to.
Dissociative Detachment and Memory Impairment: Reversible Amnesia or Encoding Failure? by Jon G, Allen, David A, Console, and Lisa Lewis The authors describe how dissociative attachment may be intertwined with neurobiological factors that impair memory.
