Abstract

Acute stress is often conceptualized as a response pattern that activates the fight-or-flight response via the sympathetic nervous system (SNS). However, other stress response patterns can manifest as well, such as parasympathetic nervous system (PNS) shutdown, and SNS-PNS coactive hypervigilance. Each response pattern engages many dimensions, including physiological, emotional, and behavioral. As stress unfolds over time, these patterns can change to adjust to the changing nature of the stressor. This proof of concept study introduces novel time series methodology to track the multidimensional patterns of acute stress. The defense cascade provides a model with which to understand and predict response patterns over the time course of an acute stressor. The time series methodology introduced in this study holds promise for identifying mechanisms of change in therapy and clinical settings. • Acute stress can trigger a range of response patterns. • The defense cascade offers a model of acute stress responses. • Virtual reality provides a dynamic threat stimulus to measure stress responses. • Sympathetic, parasympathetic, and emotion indices capture multidimensional patterns. • Time series analysis helps identify changes in response strategies.
