Article about GTP in


Here is an article about GTP especially for my Dutch friends. “Hoe games onze hersenen beïnvloeden” written by Bas Bastiaans at

Het effect van games beperkt zich niet alleen tot de huiskamer, de slaapkamer of de wc. Het kan ons hele leven beïnvloeden: onze perceptie, onze dromen en zelfs ons gedrag. Denk jij net als Ezio de Eiffeltoren wel even te beklimmen of hoor je net als Link een deuntje als je je sokkenlade opentrekt? Dan heb je wel eens Game Transfer Phenomena ervaren. Read more



Insightful article about GTP in VentureBeat

Check out this article about GTP in GamesBeat by Dan Crawley: “Seeing things: When gaming messes with reality — and your brain”

Damn Tetris blocks. Seeing them everywhere. Can’t sleep. Can’t turn them off.

For most of us, gaming offers a momentary escape from the real world, but for some, the distinction between onscreen actions and reality can blur. A recent study highlights how gaming can seriously affect our senses and offers a glimpse through the eyes of gamers whose brains keep on playing.

In the study, gamers talk about seeing a grenade icon from Call of Duty while out shopping and nearly commando-rolling away, a bedroom turning into a Minecraft-style grid, and a wide range of visual distortions that last long after a game is back in its box.

Not everyone is equally susceptible to these effects – likened to the symptoms of conditions such as epilepsy and schizophrenia – but should gamers experiencing them be concerned for their mental and physical well-being?

And does the game industry need to take notice of this research? Continue reading…

Press release about the study focusing on altered visual perceptions

Here you can read the press release we put out about the latest study.

“Study shows how video gamers experience altered visual perceptions after playing”

Some video gamers experience altered visual perceptions after playing, new research has shown. The study, published in the International Journal of Human-Computer Interaction, has been carried out by experts in Nottingham Trent University’s International Gaming Research Unit.

Led by psychologists Angelica Ortiz de Gortari and Professor Mark Griffiths, the research showed how some gamers reported distorted versions of real world surroundings. Others saw video game images and misinterpreted real life objects after they had stopped playing. Gamers reported seeing video game menus popping up in front their eyes when they were in a conversation, or saw coloured images and ‘heads up’ displays when driving on the motorway.

The study involved the analysis of 656 experiences from 483 gamers collected in 54 online video game forums.

This is the first of a series of studies that aims to identify, classify and explain ‘Game Transfer Phenomena’ (GTP) experiences via the different senses: sight, sound and touch. GTP research focuses on gamers’ perceptions, cognitions and behaviours influenced by video game playing and aims to further understanding of the psychosocial implications of altered perceptions induced by virtual technologies.
