The association between openness (assessed by shortened Chinese version of NEO Five-Factor Inventory, NEOFFI) and physiological reactivity to, and recovery from, social stress (a video-recorded, timed public speaking task with evaluators present in the room), and physiological adaptation to repeated social stress was examined in the present study. Subjective and physiological data were collected from 70 college students across five laboratory stages: baseline, stress exposure period 1, post-stress period 1, stress exposure period 2, and post-stress period 2. Results indicated that higher openness was associated with lesser heart rate (HR) reactivity to the first and second stress exposure, and lesser systolic blood pressure (SBP) reactivity to the second stress exposure. Higher openness was associated with higher resting respiratory sinus arrhythmia (RSA), lesser RSA withdrawals to the first stress exposure, and more complete RSA recovery after the first stress exposure. Moreover, higher openness was associated with pronounced systolic and diastolic blood pressure (SBP, DBP) adaptation with greater decreases in SBP and DBP reactivity across the two successive stress exposures. These findings might shed light on the biological basis linking openness to health.
本研究考察了开放性（通过中文版简版大五人格量表，即NEOFFI进行评估）与对社会压力的生理反应及恢复情况（一项有评估人员在场的录像限时公开演讲任务），以及对反复社会压力的生理适应之间的关联。在五个实验室阶段收集了70名大学生的主观和生理数据：基线期、压力暴露期1、压力后恢复期1、压力暴露期2和压力后恢复期2。结果表明，较高的开放性与对第一次和第二次压力暴露时较低的心率（HR）反应性以及对第二次压力暴露时较低的收缩压（SBP）反应性相关。较高的开放性与较高的静息呼吸性窦性心律不齐（RSA）、对第一次压力暴露时较小的RSA下降以及第一次压力暴露后更完全的RSA恢复相关。此外，较高的开放性与明显的收缩压和舒张压（SBP、DBP）适应相关，在连续两次压力暴露中SBP和DBP反应性有更大程度的降低。这些发现可能有助于揭示将开放性与健康联系起来的生物学基础。
