Key result
Arithmetical tasks outperform Stroop tests in identifying acute mental stress via short-term HRV.
Why the study?
Reliable quantitative analyses of psychophysiological measures during acute mental stress are needed to improve assessment methods.

Do acute mental stress tasks (Stroop Color Word Task and Arithmetical Task) alter psychophysiological measures compared to rest in participants?
Computational psychometrics using HRV and respiratory indices can effectively discriminate acute mental stress, potentially aiding in the automatic detection of mental stress.
Cipresso et al. (2019) conducted an observational in Acute mental stress (n=60). Acute mental stress tasks (Arithmetical Task and Stroop test) vs. Rest was evaluated on Discriminative properties of psychophysiological correlates. The Arithmetical Task demonstrated greater discrimination capability for acute mental stress compared to the Stroop test, with short-time Heart Rate Variability indices being the best predictors.
