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

2025-07-07

AI Summary

This study investigates the psychophysiological effects of video game loot boxes and their behavioral parallels with gambling, examining associations with Internet Gaming Disorder (IGD) severity. Using a standardized, researcher-developed gaming paradigm, electrodermal activity (EDA) was recorded to dissociate tonic arousal (baseline skin conductance level) from phasic, event-related responses during loot box openings. IGD severity was assessed via the IGDS9-SF. Results demonstrate, for the first time from a psychophysiological perspective, that loot box interactions elicit significant, immediate autonomic arousal—specifically, robust phasic EDA responses—and that the magnitude of this response correlates positively with IGD severity. These findings empirically substantiate loot boxes’ gambling-like reinforcement mechanisms, particularly their capacity to drive acute sympathetic activation akin to gambling cues. The study thus provides critical neurobehavioral evidence supporting regulatory scrutiny of randomized reward systems in digital games.

Abstract

This study investigates the psychophysiological effects of loot box interactions in video games and their potential similarities to those recorded during gambling interactions. Using electrodermal activity (EDA) measurements, the research examines player arousal during loot box interactions and explores the relationship between Internet Gaming Disorder (IGD) severity and loot box interactions from a psychophysiological perspective. The study employs a custom-designed game 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 both tonic and phasic components. The study contributes to the ongoing debate surrounding gaming disorder and loot boxes, offering insights for game developers and policymakers on the potential risks associated with random reward mechanisms in video games.
