First-person shooter (FPS) games are one of the most popular yet notorious genres of digital games. They contain visceral emotional content and require intense visual attention from players, leading some people to appreciate and others to resent these types of games. This thesis investigated individual differences in the game experience of FPS games by exploring how preferences for violent game dynamics (e.g., preferences for shooting, killing, and exploding) affect players’ emotions and perceptions of curiosity, vitality, and self-efficacy. In addition, the thesis explored how visual attention skills affect the viewing of FPS games as indexed by viewers’ eye movements.

In Study I, the role of visual attention skills in viewing FPS gameplay videos was explored. The results showed that viewers’ eye movements tended to progress from a diffuse scanning mode towards a more focal and central viewing mode as time passed. Visual qualities and saliency of events also guided eye movements. Individual differences in visual attention skills (namely, the ability to track multiple objects, perform a visual search for targets, and to see rapidly appearing serial targets) were related to what was attended to in the screen. The role of visual attention skills on eye movements was more prominent during visually distinct events. In sum, the results showed that specific visual attention skills predicted eye movement patterns during FPS gameplay video viewing.

Study II explored whether game dynamics preferences and emotion-related responses to an FPS game are connected. Participants’ heart rate, electrodermal activity, and electric activity of facial muscles were recorded as indexes of emotion-related responses both during playing (active participation) and gameplay video viewing (passive watching). The participants also rated their level of experienced arousal and valence. The results showed that there were individual differences in physiological emotion-related responses as a function of dynamics preferences, especially in measures of physiological arousal. Those who liked violent dynamics showed a rather stable level of physiological arousal state both when playing and when viewing the game. In contrast, participants who disliked violent dynamics showed an overall higher level of physiological arousal during playing than when viewing, and the level of arousal increased across time in both conditions. The results on facial muscle activity likewise showed that activity differed between people who liked versus disliked violent dynamics. However, the results were somewhat conflicting: those who liked violent game dynamics showed a steep increase in the activity of the corrugator supercilii muscle, an index of negative valence. Instead, those who disliked the dynamics showed less increase in corrugator supercilii activity. The dynamics preferences did not affect self-reported emotional valence or arousal. Thus, the results highlight that game dynamics preferences were associated with physiological signals, although they may not be a straightforward index of emotions in a gaming context.

In Study III, associations between game dynamics preferences and self-reported experiences of vitality, self-efficacy, and curiosity were explored both in association with life in general and with playing an FPS video game. The results showed that players who were neutral or mildly positive towards violent content experienced stable levels of vitality, curiosity, and emotional valence both in life in general and when playing. They also experienced a slight decline in self-efficacy in the playing context. Conversely, those who disliked violent dynamics experienced a clear decline in all of these measures in the playing context. Thus, game dynamics preferences were connected with wider experiential reflections related to playing.

Overall, the results of all three studies showed why there is individual variation in the playing experience: players and viewers have differing skills and preferences. These skills and preferences affect how players and viewers pay attention to the game, and what kind of emotional reactions and experiences they have. This is valuable for understanding the psychological outcomes of FPS games, as well as why people hold differing opinions about these types of games. Likewise, the results have importance for game design, as they show that players respond in different ways to game contents. Thus, it may be fruitful to personalize and tailor game contents based on players’ preferences and visual attention skills.
