Estimating physiological arousal with pupil size and skin conductance
In the fields of behavioural and psychological research, pupil size and skin conductance are two variables that provide useful information about a participant’s state of mind at a given moment. Both variables are involuntary indicators of psychophysiological responses such as alertness, arousal, or focus. Pupil size is commonly measured with a video-based eye tracker, and skin conductance is measu
