Detection of Electrodermal Activity in Pain 1

The Stroop task will be used as a mild, acute stressor since it has effects on anxiety and autonomic response. In each Stroop task condition, four coloured visual stimuli will be presented on a computer screen for 3 s with 7 s inter-stimulus interval. The stimuli will be coloured words naming the colour of the ink in the nonconflict task condition (e.g. GREEN written in green ink) and a different colour in the conflict task condition (e.g. GREEN written in red ink). The participants were asked to name the colour of the stimuli. The test will be administered using the online version of PsyToolKit (Stoet, 2021).
