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.

Resilience is an innate human capacity that holds the key to uncovering why some people rebound after trauma and others never recover. Various theories have debated mechanisms underlying resilience at psychological level but not yet incorporated neurocognitive concepts/findings. In this paper, we put forward idea cognitive flexibility moderates how well adapt adverse experiences, by shifting attention resources between cognition–emotion regulation pain perception. We begin with a consensus on definitions highlight role of appraisals in mediating process. Shared concepts among appraisal suggest cognition–emotion, as perception, are underlie respond adversity. Frontal brain circuitry sub-serves control cognition emotion, connecting experience physical pain. This suggests substantial overlap these phenomena. Empirical studies from imaging support notion. end discussion frontal network regulating resilience, including interacts cognition–emotion–pain can account for flexibilities’ processes create practical applications, analogous process, recovery neural plasticity.

When exposed to adversity, some individuals are at an increased risk of posttraumatic stress disorder, experiencing persistent biopsychosocial disturbances, whereas others adapt well, described as resilience. Resilience is a complex phenomenon conceptualized adaptation adversity influenced by individual's genetic variants, epistasis, epigenetics, and gene-by-environment interactions. Studies on psychological resilience have focused behavioral psychosocial variables with far less examination the contributions. The purpose this review identify specific variants contributing biological capacity for PubMed PsycINFO were searched using following key words: AND genotype(s). Additional articles identified from Human Genome Epidemiology Navigator term resilience, psychological. Ten studies met criteria. Six genes empirically associated resilience: serotonin-transporter-linked polymorphic region ( 5-HTTLPR), dopamine receptor D4, brain-derived neurotrophic factor BDNF), corticotropin-releasing hormone 1, oxytocin regulator G-protein signaling 2 . findings systematic suggest that L/L or L'/L' genotype 5-HTTLPR rs25531 in children/adolescents S/S S'/S' adults most frequently related Additionally, Val/Val rs6265 BDNF Caucasians was also There numerous factors complexity determining influence including analysis rs25531, assumptions mode inheritance, operationalization demographic population characteristics, sample size, other types epistasis epigenetics. While current evidence supportive, further investigation required.

Stress and anxiety pose a threat to college students' academic performance as well their long-term mental physical health, but the time constraints of rigorous schedule make it difficult offer even brief health interventions. A convenience sample full-time students at public university was recruited for 5-week study conducted mostly using an online platform. Participants were randomly assigned Mindfulness-Based Art Therapy (MBAT) intervention or Neutral Clay Task (NCT). Anxiety, perceived stress, salivary cortisol outcomes measured. total n = 77 participants completed study. The MBAT group experienced significant reductions in stress compared NCT group. Significant observed, only could be identified confounding variable. making alone is not enough induce positive responses, this suggests can, that feasible accessible services on campuses. Further refinement biological data collection analysis needed determine what mediating effects have, if any, molecular level.
