Benefits of ECG in psychological research

Electrocardiography (ECG) stands as a paramount tool, offering non-invasive insights into the heart's electrical activity. Beyond its clinical uses, the benefits of ECG in psychological research have become evident, particularly in behavioral research and psychology, as it explores the intricate connection between heart activity and both emotional and cognitive processes.

For instance, Kreibig et al. (2015) noted that ECG parameter shifts correlated with emotional reactions to varied stimuli. Equally enlightening, Hansen et al. (2003) delved into the importance of heart rate variability in stress studies, utilizing ECG to discern that stress-induced changes impact cognitive functioning. Moreover, ECG has illuminated our understanding of social dynamics. Laborde et al. (2018) observed correlations between ECG metrics and perceived social interactivity. Porges et al. (2019) further cemented this by tying heart rate variability measures with social involvement.

A standout application of ECG is heart rate variability (HRV) analysis, marking the intervals between heartbeats. This has been pivotal across research fields, from psychology to neuroscience, offering a window into the autonomic nervous system's workings and stress response mechanisms. As Thoma et al. (2013) showcased, ECG's HRV measurements accurately pinpoint stress responses in cognitive tasks. Similarly, Kemp et al. (2018) highlighted the ECG-derived HRV's potential in gauging sleep's effect on cognition. In psychiatry, Carnevali et al. (2020) endorsed HRV via ECG as instrumental in anxiety disorder management and assessment.
