Psychophysiological Alterations in Posttraumatic Stress Disorder


This talk will explore commonly used psychophysiological paradigms in PTSD research including script-driven imagery and auditory startle.  Specifically, I will present research using these paradigms that examine changes in the acute aftermath of trauma exposure and follow-up months later.  In addition, research will be presented on alterations in PTSD symptoms and psychophysiological measures before and after Cognitive Processing Therapy.  A primary aim will be to explore the question of how biological variables are  related to PTSD symptom development and how they are altered following treatment.

Learning Objectives:

  • To gain an understanding of different biological measures used in research on post traumatic stress disorder
  • To gain insight into the development of PTSD symptoms and how they are related to biological alterations
  • To explore how PTSD symptoms and biological measures change with PTSD treatment

Michael G. Griffin, PhD


My research interests lie in the interconnection between psychology and biology (psychobiology). In particular, the connection between psychological events and biological alterations. My specific research interests are primarily in the area of posttraumatic stress disorder (PTSD) and the biological alterations associated with this disorder.
