ИСТИНА

Skin conductance (SC) is a highly sensitive indicator capable of differentially reflecting the level of attention, mental workload, stress, or emotional arousal. Traditionally, SC changes are associated with stress and sympathetic arousal. More recent studies had linked SC to mental performance and found a strong correlation between stress and cognitive load. However, some environmental factors (temperature, loud noises or bright lights) and changes in the physiological state of the research participant have a great influence on SC during the study. This fact makes it difficult to analyze the obtained skin conductance curves. The proposed method of SC analysis makes it possible to reduce out artifacts, including outliers, by assigning them to one or another category of values.
