GTP is the transfer of experiences from the virtual to the physical world that comprise sensorial, perceptual, cognitive, and behavioural changes or intrusions in direct relationship to video game content/features, experiences during playing (e.g. immersion, embodiment), and game-related hardware/peripherals (e.g. gamepads).

The term “Game Transfer Phenomenon/a” (GTP) was coined by me (Angelica B. Ortiz de Gortari) in my seminal study on GTP in 2010 – an interview study with 42 Swedish frequent gamers: “Game Transfer Phenomena in video game playing: A qualitative interview study”. The study was later published in collaboration with my master and PhD supervisors in 2011.

Some individuals may be more prone to experience GTP. However, different people have had remarkably similar experiences after playing the same games.

An outstanding GTP experience that initiated the pathways into this area of research was the gamer that started seeing health bars above peoples’ heads.

The involuntary phenomena observed in GTP do not only happen due to playing video games. However, key factors involved in playing video games (usually for prolonged periods of time) such as sensory overload, high cognitive load, trance states and emotional engagement appear to ease the occurrence of such phenomena.

It is important to remember that some of the GTP can be misunderstood as pathological due to their similarity with symptoms of mental conditions (e.g., hallucinations).

I am particularly concerned and interested to inform and demystify GTP to avoid that gamers and other misinterpret GTP. Therefore, I have created a series of cartoons: “GTP adventures” to communicate my research.

I think that beyond the potential risks that GTP can pose to certain individuals and in certain circumstances, if we understand the underlying mechanisms of GTP we can apply GTP to obtain benefits (e.g., in therapy or learning).

The occurrence of GTP invites us to reflect about our vulnerability to the exposure to synthetic stimuli and the challenges that the human mind will affront due to the technology advances that are still to come.

Characteristics of GTP

  • Most GTP occur in full awake state while engaging in everyday tasks, but GTP can also manifest under hypnagogic states -borderline states between awake and sleep or while waking up.
  • In many cases GTP occur triggered by associations with game-related stimuli (e.g., objects/events simulated in the game).
  • GTP usually last for seconds or minutes, but there are reports of experiences for days, weeks or longer.
  • Reality testing remains intact, meaning that gamers know that the manifestations are not real. However, sometimes the vividness of the sensory intrusions (e.g., hearing sounds as coming from nowhere or seeing images overlaying objects) and game-related objects that evoke emotions has resulted in impulsive responses (e.g. involuntary actions). These appear to happen during episodic moments of dissociation where gamers feel as being in the game or believe for moments that the game elements are real.

Facts about GTP:

  • GTP is common among gamers (82-96% experience GTP at least once; N>6,000, 15–60 years old).
  • No gender differences have been found in most of the studies.
  • Young gamers (18–21 years old) and minors (15-18) tend to be more susceptible to GTP.
  • Most gamers consider GTP pleasurable, rather than unpleasant. Some gamers would like to induce GTP.
  • Most gamers have no negative consequences due to GTP.
  • A substantial minority (16%) reported medium to high levels of negative consequences and when the reported GTP was severe (i.e. many times and in several forms), 58% of gamers reported associated distress and/or dysfunction.
  • Confusion and sleep deprivation due to GTP has been recurrently reported.
  • Most gamers are not under the influence of a substance (e.g., medicine, psychoactive substance) when they experience GTP.
  • Most gamers who experience GTP have never used drugs; nor do they have a mental or neurological condition. However, mental disorders and drug use increase the propensity to experience GTP.

  1. I had a wierd experience of GTP in which I was experiencing GTP from one game (an online loot based game) while playing another (a wander/discovery game). I found myself getting irritated that I was incapable of finding good loot in the later game, before realizing what I was looking for was from the prior game.

  2. When I first experienced game-related hallucinations, I thought I was just young and it was my imagination. Now I’m a lot older and recently experienced some GTP. When I first looked around, I thought I was going crazy! This is amazing, I wish more people would realise how credible it is.

  3. This is happening to me after playing dead island for like 9 hours I keep hearing the music,the zombies,and the looting sound effect I’ve been hearing it all day it’s weird.

  4. Currently experiencing this now, which is how I found out about GTP. I’ve been on a three day Pokémon Leaf Green binge and I am hearing the sounds of the game. At first I thought I left my game boy on, but anytime I’d put it next to my ear I wouldn’t hear anything.

    1. I have it in my right ear from the same game lol. I’ve been bingeing it as well and was going out of my mind.

    2. I’m hearing Gameboy 8 Bit noises from Pokemon Red and Blue (Gen 1) right now as I’m attempting to get to sleep. I’ve been playing for the majority of the day and the sounds aren’t leaving my head.

  5. Play a game called one more brick
    On the play store u will continue to play after closing your eyes that night. sleep is impossible but it’s very vivid . I play without sound but a friend said he could see and hear the game when he went to bed .

  6. I literally never played video games growing up it never really interested me but recently I’ve gotten hooked on this online game my friends found and now every time I close my eyes I see the game in action and it freaks me out
