“…An increase in SCL activity was previously associated with overall higher arousal linked to a state of emotional activation, which, in contrast, decreases conditions of physiological relaxation (Malmo, 1959;Venables & Christie, 1980). Different studies have previously demonstrated increased SCL activity concerning individuals' emotional arousal and engagement (Caldas et al, 2020;McQuade et al, 2019;Ravaja et al, 2008). For what concerns EDA indices, prior research has found that positive emotions are associated with lower autonomic reactivity than negative emotions (Larsen et al, 2008), owing to their supposed lower motivational boost.…”

Objective: Previous neuroscientific research explored how both moral values and economic scenarios can influence individuals’ brain activity. This study investigated the relationship between peripheral and neural activity during fairness and unfairness perception in moral and economic conditions. Method: Thirty-one participants underwent a modified version of the Ultimatum Game, which proposed various offers (fair, unfair, equal) concerning two different contexts: economic and moral conditions. During the task, the peripheral (heart rate [HR], skin conductance level/response [SCL, SCR]) and central (oxygenated and deoxygenated hemoglobin [O2Hb, HHb]) individuals’ responses were recorded using the autonomic indices recording and functional near-infrared spectroscopy. The peripheral activity was correlated with motivational systems (Behavioral Inhibition/Activation System [BIS/BAS]) and individuals’ personality traits. Results: Findings highlighted a positive correlation between SCL and O2Hb in the dorsomedial prefrontal cortex (dmPFC) during fair, unfair, and equal offers in the economic condition and a negative correlation between SCL and O2Hb in the dmPFC for fair and equal offers in the moral condition. Also, HR negatively correlated with HHb in the dorsolateral prefrontal cortex during the presentation of equal and unfair offers in the economic condition. Finally, correlations between SCL and BAS subscales (Drive and Fun Seeking) and SCR and emotional stability trait suggested the link between motivation and emotional regulation during different conditions. Conclusions: In conclusion, the relationship between autonomic, central activity, and motivational and personality traits in moral and economic offers’ condition was discussed in light of different brain networks supporting these processes.

Electrodermal activity (EDA) has been measured in the laboratory since the late 1800s. Although the influence of sudomotor nerve activity and the sympathetic nervous system on EDA is well established, the mechanisms underlying EDA signal generation are not completely understood. Owing to simplicity of instrumentation and modern electronics, these measurements have recently seen a transfer from the laboratory to wearable devices, sparking numerous novel applications while bringing along both challenges and new opportunities. In addition to developments in electronics and miniaturization, current trends in material technology and manufacturing have sparked innovations in electrode technologies, and trends in data science such as machine learning and sensor fusion are expanding the ways that measurement data can be processed and utilized. Although challenges remain for the quality of wearable EDA measurement, ongoing research and developments may shorten the quality gap between wearable EDA and standardized recordings in the laboratory. In this topical review, we provide an overview of the basics of EDA measurement, discuss the challenges and opportunities of wearable EDA, and review recent developments in instrumentation, material technology, signal processing, modeling and data science tools that may advance the field of EDA research and applications over the coming years.
