The Trauma and Affective Psychophysiology Lab investigates the effects of chronic or complex trauma, and how these effects differ from those of an acute traumatic experience, such as a single-incident assault. Evidence suggests that acute and chronic trauma have different effects on the body and brain, which may be different not only in magnitude, but also in quality.  We explore these differences using measures of attention, cognition, and emotion, as well as physiological measures of autonomic nervous system reactivity, such as: heart rate, skin conductance, and respiratory sinus arrhythmia (RSA).
