Exploring the Cause of Game (Derived) Arousal: What Biometric Accounts of Player Experience Revealed

This research explores the drivers of game-derived arousal, challenging conventional assumptions about the relationship between "violent" game content and player response. Utilizing a mixed-method approach, the study integrates biometric data, specifically Galvanic Skin Response (GSR), with novel gameplay metrics to analyze player experience in titles such as Battlefield 3 and Dead Island. The core thesis posits that player arousal is often driven by factors beyond explicit violent themes, moving past traditional content-based classifications of game violence.

A key finding indicates that GSR data frequently diverged from content typically prioritized as "violent" in game classification systems. To analyze gameplay, a multi-layered segmentation approach was employed, categorizing player experience across dimensions like Game System, Game World, Spatial-Temporal aspects, Degree of Freedom, and Interaction. GSR served as a non-experimental, exploratory measure of arousal, with data standardization techniques, such as binning, applied to align GSR readings with in-game events like avatar health changes, enabling the identification of correlations between physiological arousal and challenging gameplay moments.

While initial analysis revealed correlations between GSR spikes and avatar health loss, a substantial portion of observed GSR activity remained unexplained by these direct in-game metrics. To delve deeper into these unexplained arousal moments, researchers developed a method for automatically generating storyboards corresponding to unaccounted GSR spikes. This allowed for detailed manual analysis of game events and player experiences that extend beyond simple combat encounters or failure scenarios, suggesting that a broader range of gameplay elements contribute to player arousal than previously understood.
