The phenomenon of presence is the subjective sense of realistic interaction with the virtual environment. Presence is an important factor in the effectiveness of the use of virtual reality systems. On the occurrence and severity of presence phenomenon influenced by both technological and psychological factors, including cognitive control. Special influence on the emergence of the phenomenon of presence can have a system of monitoring and correction of errors associated with detection and neutralization of differences between expected and actual results of the cognitive activities. It examined the extent to which the effectiveness of monitoring and error correction (estimated through the effects of slowing down after an error and adapt to the conflict) is related to the aspects of the presence phenomenon. For high-immersive (CAVE) and lowimmersive (standard display) environments, it was shown that (1) efficient error correction prevents the negative physical effects associated with the working in a virtual environment, and (2) effective detection of cognitive conflicts prevent the emergence of the phenomenon of presence through detecting unnatural virtual scenario. In low-immersive environment conflict detection also prevented the formation of emotional involvement in a virtual scenario.

The aim of the article is to give a brief overview of cognitive studies in computer games psychology. The researches of psychological specifics of computer gamers have become very important recently due to a great popularity of computer games among children, teenagers and adults all over the world. Numerous studies are made that show significant differences between cognitive characteristics of computer gamers and non-gamers. There are possible negative consequences (such as long-term memory decline) as well as positive ones. Computers games are shown to enhance attention, spatial cognition and cognitive control of computer gamers and participants of specially organized computer games sessions. Cognitive function can possibly be trained in computer games. Computer games experience affects processes of thinking, decision making as well as multitasking and task-switching capability. Studies of connection between cognitive styles and computer games are also reviewed.
