Psychophysiology is the branch of psychology that is concerned with the physiological bases of psychological processes. While psychophysiology was a general broad field of research in the 1960s and 1970s, it has now become quite specialized, based on methods, topic of studies and scientific traditions. Methods vary as combinations of electrophysiological methods, neuroimaging, and neurochemistry. Topics have branched into subspecializations such as social, sport, cognitive, cardiovascular, clinical and other branches of psychophysiology.

Biofeedback is the process of gaining greater awareness of many physiological functions of one's own body by using electronic or other instruments, and with a goal of being able to manipulate the body's systems at will. Humans conduct biofeedback naturally all the time, at varied levels of consciousness and intentionality. Biofeedback and the biofeedback loop can also be thought of as self-regulation. Some of the processes that can be controlled include brainwaves, muscle tone, skin conductance, heart rate and pain perception.
Video game modding is the process of alteration by players or fans of one or more aspects of a video game, such as how it looks or behaves, and is a sub-discipline of general modding. Mods may range from small changes and tweaks to complete overhauls, and can extend the replay value and interest of the game.
Gameplay is the specific way in which players interact with a game, and in particular with video games. Gameplay is the pattern defined through the game rules, connection between player and the game, challenges and overcoming them, plot and player's connection with it. Video game gameplay is distinct from graphics and audio elements. In card games, the equivalent term is play.
Steam is a video game digital distribution service and storefront from Valve. It was launched as a software client in September 2003 as a way for Valve to provide automatic updates for their games, and expanded to distributing third-party game publishers' titles in late 2005. Steam offers various features, like digital rights management (DRM), game server matchmaking, anti-cheat measures, social networking and game streaming services. Users receive automatic game updates, cloud storage for game progress, and community features such as direct messaging, in-game chats and a community market.
A playtest is the process by which a game designer tests a new game for bugs and design flaws before releasing it to market. Playtests can be run "open", "closed", "beta", or otherwise, and are very common with board games, collectible card games, puzzle hunts, role-playing games, and video games, for which they have become an established part of the quality control process. An individual involved in testing a game is referred to as a playtester.
Game balance is a branch of game design that is described as a mathematical-algorithmic model of a game's numbers, game mechanics, and relations between the two. Game balance consists of adjusting values to create a certain user experience. Players’ perception and experience are the objectives of game balancing.
Health psychology is the study of psychological and behavioral processes in health, illness, and healthcare. The discipline is concerned with understanding how psychological, behavioral, and cultural factors contribute to physical health and illness. Psychological factors can affect health directly. For example, chronically occurring environmental stressors affecting the hypothalamic–pituitary–adrenal axis, cumulatively, can harm health. Behavioral factors can also affect a person's health. For example, certain behaviors can, over time, harm or enhance health. Health psychologists take a biopsychosocial approach. In other words, health psychologists understand health to be the product not only of biological processes but also of psychological, behavioral, and social processes.
In video games, artificial intelligence (AI) is used to generate responsive, adaptive or intelligent behaviors primarily in non-player characters (NPCs) similar to human-like intelligence. Artificial intelligence has been an integral part of video games since their inception in the 1950s. AI in video games is a distinct subfield and differs from academic AI. It serves to improve the game-player experience rather than machine learning or decision making. During the golden age of arcade video games the idea of AI opponents was largely popularized in the form of graduated difficulty levels, distinct movement patterns, and in-game events dependent on the player's input. Modern games often implement existing techniques such as pathfinding and decision trees to guide the actions of NPCs. AI is often used in mechanisms which are not immediately visible to the user, such as data mining and procedural-content generation.
Affective design describes the design of user interfaces in which emotional information is communicated to the computer from the user in a natural and comfortable way. The computer processes the emotional information and adapts or responds to try to improve the interaction in some way. The notion of affective design emerged from the field of human–computer interaction (HCI), specifically from the developing area of affective computing. Affective design serves an important role in user experience (UX) as it contributes to the improvement of the user's personal condition in relation to the computing system. The goals of affective design focus on providing users with an optimal, proactive experience. Amongst overlap with several fields, applications of affective design include ambient intelligence, human–robot interaction, and video games.
Media psychology is the branch and specialty field in psychology that focuses on the interaction of human behavior with media and technology. Media psychology is not limited to mass media or media content; it includes all forms of mediated communication and media technology-related behaviors, such as the use, design, impact, and sharing behaviors. This branch is a relatively new field of study because of advancement in technology. It uses various methods of critical analysis and investigation to develop a working model of a user's perception of media experience. These methods are used for society as a whole and on an individual basis. Media psychologists are able to perform activities that include consulting, design, and production in various media like television, video games, films, and news broadcasting. Media psychologists are not considered to be those who are featured in media, rather than those who research, work or contribute to the field.
Neal Elgar Miller was an American experimental psychologist. Described as an energetic man with a variety of interests, including physics, biology and writing, Miller entered the field of psychology to pursue these. With a background training in the sciences, he was inspired by professors and leading psychologists at the time to work on various areas in behavioral psychology and physiological psychology, specifically, relating visceral responses to behavior.
Dynamic game difficulty balancing (DGDB), also known as dynamic difficulty adjustment (DDA) or dynamic game balancing (DGB), is the process of automatically changing parameters, scenarios, and behaviors in a video game in real-time, based on the player's ability, in order to avoid making the player bored or frustrated. The goal of dynamic difficulty balancing is to keep the user interested from the beginning to the end, providing a good level of challenge.
Sport psychology was defined by the European Federation of Sport in 1996, as the study of the psychological basis, processes, and effects of sport. Otherwise, sport is considered as any physical activity where the individuals engage for competition and health. Sport psychology is recognized as an interdisciplinary science that draws on knowledge from many related fields including biomechanics, physiology, kinesiology and psychology. It involves the study of how psychological factors affect performance and how participation in sport and exercise affect psychological and physical factors. Sport psychologists teach cognitive and behavioral strategies to athletes in order to improve their experience and performance in sports. In addition to instruction and training of psychological skills for performance improvement, applied sport psychology may include work with athletes, coaches, and parents regarding injury, rehabilitation, communication, team building, and career transitions.
User experience evaluation (UXE) or user experience assessment (UXA) refers to a collection of methods, skills and tools utilized to uncover how a person perceives a system before, during and after interacting with it. It is non-trivial to assess user experience since user experience is subjective, context-dependent and dynamic over time. For a UXA study to be successful, the researcher has to select the right dimensions, constructs, and methods and target the research for the specific area of interest such as game, transportation, mobile, etc.
SteamOS is a Linux distribution developed by Valve. It is open source with some closed source components and is the primary operating system for Steam Machines and the Steam Deck.
Early access, also known as alpha access, alpha founding, paid alpha, or game preview, is a funding model in the video game industry by which consumers can purchase and play a game in the various pre-release development cycles, such as pre-alpha, alpha, and/or beta, while the developer is able to use those funds to continue further development on the game. Those that pay to participate typically help to debug the game, provide feedback and suggestions, may have access to special materials in the game. The early-access approach is a common way to obtain funding for indie games, and may also be used along with other funding mechanisms, including crowdfunding. Many crowdfunding projects promise to offer access to alpha and/or beta versions of the game as development progresses; however, unlike some of these projects which solicit funds but do not yet have a playable game, all early access games offer an immediately playable version of the unfinished game to players.
Video game monetization is a type of process that a video game publisher can use to generate revenue from a video game product. The methods of monetization may vary between games, especially when they come from different genres or platforms, but they all serve the same purpose to return money to the game developers, copyright owners, and other stakeholders. As the monetization methods continue to diversify, they also affect the game design in a way that sometimes leads to criticism.
