Abstract:Measuring psychophysiology is an objective way to estimate cognitive states such as perceived stress. Available renowned physiological measuring devices are often expensive and lack transparency in how data is processed. Both play a factor in the shortage of hands-on psychophysiological education in some universities. Fortunately, the YLab initiative of the University of Twente has the goal to change that. The YLab initiative is creating a platform where students can access inexpensive hardware and free software to build physiological measurement devices. One such device is the YLab initiative’s first prototype. This YLab prototype was to be experimentally validated in measuring stress against the renowned Empatica E4. The experiment included a baseline measurement, a subjective stress scale, and an adjusted Sing-a-Song Stress Task (SSST). During the experiment, both devices recorded the participants' electrodermal activity (EDA) and heart rate (HR). 12 participants were recruited through convenience sampling. The validation of the YLab prototype was unsuccessful thus far, partially because of the novelty of this prototype and the barricades in terms of transparency and compatibility of the E4. Difficulties were encountered with synchronizing the devices and pre-processing the YLab data. Despite that, an important step towards the validation of the YLab prototype was taken.
