Digital media and wellbeing among children and adolescents in Ticino

Digital Lives


DIGITAL LIVES: WHAT DOES SMARTPHONE-MEDIATED COMMUNICATION FEEL LIKE? is a research project conducted between 2018 and 2020. The aim of the project was to better understand the effects of instant messaging platforms such as WhatsApp among young adults. The project used an innovative approach and combined different methodologies. In an experimental setting, the research team introduced psychophysiological measures of heart rate and electrodermal activity to obtain an objective and real-time response to messages sent via WhatsApp. The messages were manipulated with regards to their valence (es. positive vs negative) and latency (es. immediate vs delayed response). This allowed studying which aspects of instant messaging induced arousal and how this arousal was perceived. The project was funded by the Swiss National Science Foundation and conducted in collaboration with the DCMlab of the University of Fribourg.
