Using Psychophysiological Insights to Evaluate the Impact of Loot Boxes on Arousal

This study investigates the psychophysiological effects of loot box interactions in video games and their potential similarities to gambling-related behaviours. Using electrodermal activity (EDA) measurements, the research examines player arousal during loot box interactions and explores whether individuals with higher Internet Gaming Disorder (IGD) severity exhibit reduced sensitivity to these random reward mechanisms. The study employs a custom-designed game, ``A Minute Outside,'' to control experimental conditions and standardise loot box interactions. Participants' IGD severity is assessed using the Internet Gaming Disorder Scale – Short Form (IGDS9-SF), while arousal is measured through EDA, analysing skin conductance responses (SCRs), area under the curve (AUC), and skin conductance level (SCL). By leveraging psychophysiological methods commonly used in gambling research, this investigation aims to provide objective evidence on whether loot boxes function as gambling-like mechanisms at a physiological level. The study contributes to the ongoing debate surrounding gaming disorder and loot box harms, offering insights for game developers and policymakers on the potential risks associated with these monetisation strategies.
