The aim of the present research was to analyse the subjective and objective psychophysiological stress response of experienced and non-experienced Pharmacy and Biotechnology students in laboratory practices. We analysed in 82 Pharmacy and Biotechnology degree students divided into two groups (non-experienced: n: 53; experienced: n: 29) the autonomic stress response by the analysis of heart rate variability (HRV) before, during and after and distress perception before and after a laboratory practice. Results showed how students in both groups presented a large anticipatory anxiety response at the beginning of the practise (low HRV values). During the entire laboratory practice, non-experienced students showed a maintained sympathetic modulation while experienced students presented a higher parasympathetic modulation (high HRV values) consistent with a habituation process. Laboratory practise performed by Pharmacy and Biotechnology students produced an anticipatory anxiety response independently of their experience, but, non-experienced students showed a lower habituation response in both subjective and objective stress records than experienced students at the end of the laboratory practice.
本研究的目的是分析有经验和无经验的药学与生物技术专业学生在实验室实践中的主观和客观心理生理应激反应。我们对82名药学与生物技术专业的学生进行了分析，将他们分为两组（无经验组：n = 53；有经验组：n = 29），通过分析心率变异性（HRV），在实验室实践前、中、后测量自主应激反应，并在实践前后测量苦恼感知。结果显示，两组学生在实践开始时（HRV值较低）均表现出强烈的预期焦虑反应。在整个实验室实践过程中，无经验的学生表现出持续的交感神经调节，而有经验的学生则表现出更高的副交感神经调节（HRV值较高），这与习惯化过程一致。药学与生物技术专业学生进行的实验室实践会产生预期焦虑反应，且与他们的经验无关，但在实验室实践结束时，无经验的学生在主观和客观应激记录中的习惯化反应均低于有经验的学生。
