视频游戏对认知能力的影响及其神经基础

视频游戏是一类需要借助视听设备并基于一定剧情进行操作的游戏。先前研究大多关注暴力视频游戏对攻击等负面行为的影响,但本文着重探讨视频游戏对个体认知能力的积极影响及内在神经基础,以辩证看待视频游戏对个体心理和行为的作用。本文对前人研究归纳梳理发现,视频游戏训练能使个体认知能力得到持久改善,同时论述了视频游戏中脑神经基础和奖赏预期对认知能力的调控作用。未来研究应在规范视频游戏训练技术的基础上,用其干预靶脑区以提升个体特定脑功能。     

Motivational Effects of Adding Context Relevant Stress in PC-Based Game Training

This work was designed to examine the effects of contextually relevant stress on personal computer (PC)-based game training. Off-the-shelf PC-based games are being applied to many training situations because of their affordability, flexibility, and teaming capabilities. The ultimate purpose of training is to transfer superior performance to the real world. In this respect, 1 of the major drawbacks to using games as training tools, especially for military applications, is the absence of the surrounding context. In response to this omission, we examined the effects of adding context-rele-vant stress to infantry game-based training by exposing 1 group of participants to a graphically intense and stressful experience while the control group viewed an unstressful analog. Pre–post self-reported stress levels confirmed the efficacy of this manipulation. The stress condition produced significantly higher scores on “mission success”; however, no differences were evident in participants’ use of trained tactics or game functions. Supplementing context-relevant stress in game training shows promise for enhancing individuals’ motivation to succeed.     

The difference between playing games with and without the computer: a preliminary view

The authors address the question of whether associations between video games and cognitive and metacognitive variables depend either on the features of the computer or on the content of the game that the computer allows one to play. An experiment to separate these two kinds of effects was carried out by using a traditional version and a computer-supported version of Pegopolis, a solitaire game. The two versions were exactly the same except that they were played by moving pieces either on a real board or on a virtual computer-presented board. The performance levels and strategies followed during the game by the 40 undergraduates who took part in the experiment were not significantly different in the real and virtual conditions. None of the participants transferred playing strategies or practice from one version of the game to the other. Scores were not affected by gender or by the studies pursued by participants, the habit of playing games in the traditional manner or playing video games, or intelligence. Retrospective reports did not support differences in the subjective experience between the two versions. Results showed that video games, when they do not make much use of the computer's special features, produce effects because of the situations they simulate rather than because of features of the computer itself.     

Do Computer-Based Games Facilitate Knowledge Acquisition and Retention?

This study investigated the effects of a gaming approach on knowledge acquisition and retention in military trainees. Three groups of trainees were presented with subject matter in paper-based prose form (text), paper-based question-and-answer form (test), or computer-based gaming form (game). These conditions were selected to investigate potential benefits of computer-based gaming over traditional paper-and-pencil media in terms of trainee performance and reaction. Results showed that participants assigned to the game condition scored significantly higher on a retention test com- pared to pretest performance. Furthermore, participants assigned to the game condition scored significantly higher on a retention test than did participants assigned to the text condition. Participants assigned to the test and text conditions showed no benefit from training in performance at the retention test. In addition, participants assigned to the game condition rated the training they received as more enjoyable and more effective than did those assigned to the other 2 conditions. Results are discussed in terms of the effectiveness of computer-based games for military training applications.     

网络游戏中化身参照的加工优势：来自行为与ERPs的证据

采用R/K范式和事件相关电位技术(ERPs)分别从加工结果和加工过程考察网络游戏中化身参照的加工优势。实验1采用R/K范式比较40名玩家在不同参照条件下的记忆成绩。结果发现：化身参照的总再认正确率、R反应再认正确率和辨别力d'都显著优于他人参照, 初步证实化身参照的记忆加工优势。实验2借助ERPs内隐地考察网络游戏中20名玩家的化身参照在加工时间进程上的神经机制。结果发现：加工化身名字比熟悉他人名字诱发更大的P2 (160~260 ms)和P3 (370~600 ms)波幅, 比外国熟悉他人名字的P3潜伏期更短。结果表明, 相比较其他信息, 玩家不仅能够迅速注意到化身相关信息, 还对化身相关信息进行了更加精细和深入地加工。综上所述, 无论是记忆结果还是加工时间进程, 都存在网络游戏中的化身参照加工优势。     

Information and the complementarity game

Complementarity games are explorative games between two players. The deterministic rules of the game are known to both players. The first player freely chooses among a finite number of states of the game but tells nobody of this decision. The second player accesses the game only by primitive, symbolic input‐output interfaces. The task of the second player is to find out the unknown state by input‐output experiments. The logic resulting from this scenario resembles‐ quantum logic in many aspects. It is the empirical logic of choice for virtual realities.     

Playing With Prejudice: The Prevalence and Consequences of Racial Stereotypes in Video Games

A content analysis of top-selling video game magazines (Study 1) and of 149 video game covers (Study 2) demonstrated the commonality of overt racial stereotyping. Both studies revealed that minority females are virtually absent in game representations. Study 1 revealed that, in video game magazines, minority males, underrepresented generally, were more likely to be portrayed as athletes or as aggressive, and less likely to be depicted in military combat or using technology, than White males. Study 2 also showed evidence of the “dangerous” minority male stereotype in video game covers. Again, underrepresented overall, minority males were overrepresented as thugs, using extreme guns, and also as athletes. Study 3, an experiment, exposed players to both violent and nonviolent games with both White and Black characters. Participants were faster at classifying violent stimuli following games with Black characters and at classifying nonviolent stimuli following games with White characters, indicating that images of popular video game characters evoke racial stereotypes.     

The role of mental rotation in TetrisTM gameplay: An ACT-R computational cognitive model

The mental rotation ability is an essential spatial reasoning skill in human cognition and has proven to be an essential predictor of mathematical and STEM skills, critical and computational thinking. Despite its importance, little is known about when and how mental rotation processes are activated in games explicitly targeting spatial reasoning tasks. In particular, the relationship between spatial abilities and Tetris^TM has been analysed several times in the literature. However, these analyses have shown contrasting results between the effectiveness of Tetris-based training activities to improve mental rotation skills. In this work, we studied whether, and under what conditions, such ability is used in the Tetris^TM game by explicitly modelling mental rotation via an ACT-R based cognitive model controlling a virtual agent. The obtained results show meaningful insights into the activation of mental rotation during game dynamics. The study suggests the necessity to adapt game dynamics in order to force the activation of this process and, therefore, can be of inspiration to design learning activities based on Tetris^TM or re-design the game itself to improve its educational effectiveness.     

Just a Game? Unjustified Virtual Violence Produces Guilt in Empathetic Players

Many avid gamers discount violent conduct in video games as morally insignificant as “it is just a game.” However, recent debates among users, regarding video games featuring inappropriate forms of virtual violence, suggest a more complex truth. Two experiments (N₁ = 49, N₂ = 80) examined users' guilt responses in order to explore the moral significance of virtual violence. In both studies, justification of virtual violence and users' trait empathy determined guilt in a structurally similar way to real-world scenarios: People felt guiltier if they engaged in unjustified virtual violence, especially if they were empathetic players. These results show that video games are capable of inducing affective moral responses in users. Accordingly, virtual violence may be considered morally significant action.     

The Motivational Pull of Video Games: A Self-Determination Theory Approach

Four studies apply self-determination theory (SDT; Ryan & Deci, 2000) in investigating motivation for computer game play, and the effects of game play on well-being. Studies 1–3 examine individuals playing 1, 2 and 4 games, respectively and show that perceived in-game autonomy and competence are associated with game enjoyment, preferences, and changes in well-being pre- to post-play. Competence and autonomy perceptions are also related to the intuitive nature of game controls, and the sense of presence or immersion in participants’ game play experiences. Study 4 surveys an on-line community with experience in multi-player games. Results show that SDT’s theorized needs for autonomy, competence, and relatedness independently predict enjoyment and future game play. The SDT model is also compared with Yee’s (2005) motivation taxonomy of game play motivations. Results are discussed in terms of the relatively unexplored landscape of human motivation within virtual worlds.     

Having The Last Laugh: The Value of Humour in Invasion Games

This paper provides an existential analysis of humour as a social virtue in invasion games at the elite sport level. The main argument is that humour in this particular context can be valuable both in the competitive social training environment and in game performance. This is investigated through philosophical and psychological conceptualisations of humour that are used to reveal and analyse the appearance and possible value of a humorous approach in various social situations experienced during invasion games and the associated training situations. It is concluded that humour can help balance and structure the social training environment as well as facilitate creative game performance. On this basis it is suggested that the existential perspectives on humour presented could make a fruitful contribution to talent development in the domain of invasion games.     

Reciprocal trust mediates deep transfer of learning between games of strategic interaction

We studied transfer of learning across two games of strategic interaction. We found that the interpersonal relation between two players during and across two games influence development of reciprocal trust and transfer of learning from one game to another. We show that two types of similarities between the games affect transfer: (1) deep similarities facilitate transfer of an optimal solution across games; (2) surface similarities can either facilitate or hinder transfer depending on whether they lead players toward an optimal or sub-optimal solution in the target game. Learning an optimal solution in a context of interdependence between players is associated with development of reciprocal trust, which in turn mediates transfer of learning across games. The results can be used to inform the design of training exercises to develop strategic interaction skills.

Does driving experience in video games count? Hazard anticipation and visual exploration of male gamers as function of driving experience

Risk perception and distribution of visual attention while driving are crucial elements for accident prevention and new-driver improvement. This study investigates how racing videogames could shape the visual exploration of virtual and real road in male pre-drivers. The visual performance of players of racing video games with and without driver’s license was tested in virtual vs. real scenarios. Attention to specific elements of different types of road interactions was monitored using an eye-tracking system. Results showed that habitual use of racing video games was not found to foster a positive effect on users’ distribution of visual attention, supporting visual patterns typical of novice drivers. Gamers without driving experience replicated the same patterns in a real road scenario, ignoring road signs and potential areas of interactions with other drivers, while experienced drivers gamers explored video games roads like real roads. The fact that the gamers’ driving performance was not comparable to drivers in the virtual scenario suggests that there are other variables in the gameplay that create a less complex traffic scene, still the visual complexity of different real road interactions is kept in video game interactions, opening new perspectives towards gamers’ visual exploration of the road.     

Game relativity: how context influences strategic decision making

Existing models of strategic decision making typically assume that only the attributes of the currently played game need be considered when reaching a decision. The results presented in this article demonstrate that the so-called "co-operativeness" of the previously played prisoner's dilemma games influence choices and predictions in the current prisoner's dilemma game, which suggests that games are not considered independently. These effects involved reinforcement-based assimilation to the previous choices and also a perceptual contrast of the present game with preceding games, depending on the range and the rank of their co-operativeness. A. Parducci's (1965) range frequency theory and H. Helson's (1964) adaptation level theory are plausible theories of relative judgment of magnitude information, which could provide an account of these context effects.     

"I'm attached, and I'm a good guy/gal!": how character attachment influences pro- and anti-social motivations to play massively multiplayer online role-playing games

One's feelings of intimacy and connectedness with distal, fictional media characters are referred to as parasocial interactions. Video games have challenged this concept, as the distance between game players and characters is greatly reduced, if not completely removed, in virtual environments. Games encourage the internalization and psychological merging of a player's and a character's mind, a multidimensional concept known as character attachment (CA). Data from our study suggest that dimensions of CA are useful in understanding both pro- and anti-social gaming motivations. Pro-social gamers feel a greater sense of control over their characters, while anti-social gamers are more likely to suspend their disbelief of the game environment and not take responsibility for their virtual actions. Pro-social gaming was more prevalent in older gamers, and younger male game characters were motivated by anti-social reasons.     

Gut or Game? The Influence of Moral Intuitions on Decisions in Video Games

Recent theorizing on the role of morality in media entertainment suggests morality serves as a guiding force in audience reactions to content. Using moral foundations theory as a base, research has found significant associations between moral salience and audience preferences for and responses to film and television varying in their presentations of morality. Our study extends this work by testing the same relationship in video games. Because a distinguishing factor between video games and traditional media is interactivity, our study focuses on how moral salience predicts decisions made in a video game. We find that increased moral salience led to a decreased probability of moral violations, while decreased moral salience led to an observed random (50%) distribution of violations. This finding was largely stable across different morality subcultures (German, United States) and age groups (adolescents and elderly), with deviations from this pattern explained by theory. We interpret this as evidence for a gut or game explanation of decision making in video games. When users encounter virtual scenarios that prime their moral sensitivities, they rely on their moral intuitions; otherwise, they make satisficing decisions not as an indication of moral corruption but merely as a continuation of the virtual experience.     

Seven‐year‐olds’ aggressive choices in a computer game can be predicted in infancy

Concerns about the relationship between computer games and children's aggression have been expressed for decades, but it is not yet clear whether the content of such games evokes aggression or a prior history of aggression promotes children's interest in aggressive games. Two hundred and sixty‐six 7‐year‐old children from a nationally representative longitudinal sample in the UK played a novel computer game (CAMGAME) in which the child's avatar encountered a series of social challenges that might evoke aggressive, prosocial or neutral behaviour. Aggressive choices during the game were predicted by well‐known risk factors for aggressive conduct problems and the children's own early angry aggressiveness as infants. These findings suggest that children who are predisposed to aggression bring those tendencies to virtual as well as real environments.     

Physical interpersonal relationships and social anxiety among online game players.

Many online game players spend inordinate amounts of time in their favorite virtual worlds. A large percentage of these players are teenagers who show behaviors normally associated with physical addiction. Parents, educators, and social scientists are therefore saying that online games are sources of social problems. The authors surveyed 174 Taiwanese college-age online players to collect data on the potential effects of online games on the quality of interpersonal relationships and levels of social anxiety. According to the results, the quality of interpersonal relationships decreased and the amount of social anxiety increased as the amount of time spent playing online games increased.
