This study aims to find out what drives players to the horror genre and to experience fear, an emotion that is usually instinctively avoided. Since horror is an explicit genre that often exploits and explores violence and cruelty I want to analyze psychological reasoning behind players who consciously immerse in this type of games. As a fundamental question I want to measure the extent of lowering players' boundaries of acceptable behavior outside the game by engaging in violent actions and observing it happen on the screen. In this study I want to study the emotional and reactionary response on scary and unsettling moments in videogames as well as to study the psychology of the horror genre and common techniques for intimidating a player. To test the aforementioned hypothesis I will use a randomized control trial where gamer participants who haven't played the horror games in general will answer questions that will measure their accepted violence boundaries in real life. Then all of them except the control group will be asked to play a certain horror game, and afterwards both groups will answer another poll. Questions they will be given is incredibly important, because this trial depends on their precision and obscurity.
