Measurement of Electrodermal Activity in Marketing Research

“…Tonic activity is an expression of changes occurring in the general level of autonomous stimulation (Bazarnik, 2016) and refers to the characteristics of the background signal (i.e. general level, slow increase or slow decrease in time) (Braithwaite et al, 2013). In the case of the tonic level, there are only slight changes over several dozen seconds or several minutes.…”

“…The recording of electrodermal activity provides information about the mean and standard deviation of the skin conductance response (SCR) -these measures include converting raw SCR into a standardised Z-result (with a normal distribution, a mean of 0 and a standard deviation of 1). The most commonly used measure of phase activity is amplitude, which is calculated as the difference between peak skin conductance response (SCR) and the low point before this peak (BIOPAC, 2017; Braithwaite et al, 2013;Naqvi, Bechara, 2006). In other words, it is a phase increase in skin conductance shortly after the onset of the stimulus (Dawson et al, 2007).…”

“…EDA finds application as an indicator of processes such as attention, habituation, arousal and cognitive effort, which is used in research in many disciplines (Figner, Murphy, 2011). Studies on the electrical activity of the skin are used, among others in research in the field of psychopathology, personality disorders, conditioning or neuropsychology, as well as in marketing (Braithwaite et al, 2013).…”

“…EDA is a measure of psychophysiological activity, which is an indicator of changes in the arousal of the sympathetic system. It is worth noting that it is the only psychophysiological parameter sensitive to changes in emotional states or cognitive activity, that is not affected by the activity of the parasympathetic system (Braithwaite, Watson, Jones, Rowe, 2013). Electrodermal activity is connected with the stimulation of the sympathetic system that operates during heightened alertness.…”
