Pilots' operation behavior in flight is associated with their mental state variables such as workload, situation awareness, stress, etc. The objective of this study was to investigate the dynamic process workload for pilots who perform a risky task simulated scenarios. Two empirical experiments were conducted address issue. In experiment one, 19 trainee divided into high-risk and low-risk groups performed target-search low-altitude visual flight. results showed statistically significant interaction between segments heart rate variability (HRV). same pattern physiological replicated among participants two, which airline completed an approach low visibility. These findings highlighted relationship variation risk-taking behavior, could be considered improving pilot selection training improve safety.

Heart Rate Variability Biofeedback (HRVB) has been widely used to improve cardiovascular health and well-being. HRVB is based on breathing at an individual's resonance frequency, which stimulates respiratory sinus arrhythmia (RSA) the baroreflex. There is, however, no methodological consensus how apply HRVB, while details about protocol are often not well reported.

Post-traumatic stress disorder (PTSD) is a chronic condition characterized by symptoms of physiological and psychosocial burden. While growing research demonstrated signs inflammation in PTSD, specific biomarkers that may be representative PTSD such as the detailed neural correlates underlying inflammatory responses relation to trauma exposure are seldom discussed.

Stressful life events are an important cause of psychopathology. Humans exposed to aversive or stressful experiences show considerable inter-individual heterogeneity in their responses. However, the majority does not develop stress-related psychiatric disorders. The dynamic processes encompassing positive and functional adaptation face significant adversity have been broadly defined as resilience. Traditionally, assessment resilience has confined self-report measures, both within general community putative high-risk populations. Although this approach value, it is highly susceptible subjective bias may capture nature resilience, underlying construct.

Although prior research has examined how early adversity and chronic stress exposure relate to hypothalamic-pituitary-adrenal (HPA) axis responses acute stress, date, no studies have stressors occurring over the entire lifespan predict such responses. To address this issue, we recruited 61 healthy young adults measured their 55 different types of life events difficulties lifespan. In addition, characterized differences in participants' HPA by measuring salivary cortisol DHEA Trier Social Stress Test for Groups. Greater cumulative was associated with a blunted response, but heightened stressor. Moreover, it these (i.e., lifetime count), not perceived severity, which predicted stress.
