  1. The EDAsymp index quantifies the activity of the sympathetic nervous system, while the EDAHFnu index quantifies the sympthovagal balance. A full description is available in the sections Description and analysis of physio data and New index from the sympathovagal assessment in Methods. Human-likeness is Low when the participant rating is in the lower side of the distribution on the 7-likert scale, and High otherwise. The number of observations are in squared brackets.
