Resilience–related physiological features and allostasis during critical events in a job–specific serious game

The main aim of this research is to investigate whether the features extracted from physiological signals during a relatively short generic stimulation paradigm can predict characteristics of subsequent allostatic physiological responses to critical events in job–specific stressful situations. The generic stimulation paradigm has been designed to elicit physiological response features which have been empirically tested in stress resilience/vulnerability research and should be generally applicable for stress resilience/vulnerability prediction in stressful professions like first responders, special forces, air traffic controllers etc. Specifically, the stimulation paradigm includes well–established generic stressful emotional stimuli: acoustic startle (AS), airblast, and aversive images and sounds, with a resting and a recovery period, at the beginning and the end of the paradigm. The elicited and assessed physiological features are related to (a) resting cardiac activity: resting heart rate, resting heart rate variability (interpreted as resting vagal control), and resting respiratory sinus arrhythmia (RSA) ; (b) AS response–related features: fear potentiated startle (FPS), prepulse inhibition (PPI), safety inhibition, habituation of the AS responses, and fear/threat vs. safety discrimination ; (c) reaction and recovery of cardiac and electrodermal features to generic fear/threat inducing stimuli.
