Description
Summary:Mental stress and unpleasant emotions are significant issues at the moment due to the COVID-19 pandemic, which has been spreading globally for more than a year. During the pandemic, every daily activity was oriented around utilizing an online platform to speak with one another within a company or regarding personal matters. However, how the psychophysiological state is perpetuated while engaging in online engagement is currently limited. Previous research has established a strong correlation between psychophysiological characteristics and diverse contexts. Four university students participated in this study. Each subject needed to follow four stages during an experimental design procedure called Trier Social Stress Test (TSST) namely R1, R2, R3, and R4. We retrieved the physiological and psychological data during the experiment. We observed that the mental and emotional changes that occur during the TSST procedure correlate with physiological features measured using short-term pulse rate variability in both linear and non-linear time series analysis. During an online interview, we discovered that the variation of peak-to-peak intervals was more remarkable in the post-interview session (R3) than during the baseline (R1), and pre-interview session (R2), particularly for the pSD2 parameter, which changed at a rate of 4.235 (0.017 to 0.089 seconds) on a subject. Additionally, we discovered a substantial correlation between negative emotions as measured by PANAS scores and stress level scales (\mathrm{r}=0.81 , p
