A study from a British university has claimed some gamers who play for extended periods of time begin to hear sound effects in their heads, including "maddening" screams.
Nottingham Trent University explored something referred to as game transfer phenomena, when players find that gaming influences either their perceptions or behaviors out in the real-world. Of the 1,244 players who were surveyed, one in ten experienced auditory hallucinations after they'd put down the controller, including the whistling of bullets, the pew pew of lasers, beeping or the sound of vehicles.
In one of the more extreme cases, a gamer heard the word 'death' whispered over and over again for days, and another heard the words 'go, go, go' whenever he was near crowds. "These experiences can sometimes result in illogical thoughts and behaviors," a psych researcher from Nottingham Trent, Angelica Ortiz, said. "It's important to help gamers understand their experiences since re-experiencing sounds and voices may provoke distress, especially when associated with dangerous situations in the game."
