Is cheating a human function? The roles of presence,state hostility,and enjoyment in an unfair video game

In sports and board games, when an opponent cheats, the other players typically greet it with disdain, anger, and disengagement. However, work has yet to fully address the role of the computer cheating in video games. In this study, participants played either a cheating or a non-cheating version of a modified open-source tower-defense game. Results indicate that when a computer competitor cheats, players perceive the opponent as being more human. Cheating also increases player aggravation and presence, but does not affect enjoyment of the experience. Additionally, players that firmly believed that their opponent was controlled by the computer exhibited significantly less state hostility compared to players that were less certain of the nature of their competitor. Game designers can integrate subtle levels of cheating into computer opponents without any real negative responses from the players. The results indicate that minor levels of cheating might also increase player engagement with video games.     

Impasse-driven learning in the context of video games

This study was designed to elucidate the problem-solving skills used by frequent and infrequent video game players to negotiate impasses encountered while playing a novel video game. All participants were instructed to think aloud while playing a video game for 20 consecutive minutes. Comments made were then used to make inferences about the problem-solving skills that participants used to resolve impasses encountered during the game. Findings showed that frequent players made significantly greater reference to insight and game strategies than infrequent players. After reaching an impasse, all players also were most likely to comment on their game progress and potential game strategies to use. Over the course of game play, all participants showed increasing emphasis on their problem-solving skills as evidenced through their greater mention of insight, game strategies, and goal comments.     

Engagement in digital entertainment games: A systematic review

Since their introduction over 40 years ago, digital entertainment games have become one of the most popular leisure activities globally. While digital games clearly provide highly engaging activities, the nature of this engagement is not well understood. The current study aims to advance our understanding by reporting a systematic review of recent literature addressing engagement in computer games. The papers in the review comprise a sub-sample of papers relating to engagement in digital games that was selected from a broader literature search carried out on the outcomes and impacts of playing computer games. A diverse range of studies was identified that examined varied aspects of engagement in games including subjective experiences while playing games, the physiological concomitants of these experiences, motives for playing games, game usage and time spent playing games and the impact of playing on life satisfaction. A narrative review was carried out to capture these diverse aspects of engagement and to develop a more coherent understanding of engagement in computer games.

The effect of violent and non-violent computer games on cognitive performance

Two studies were conducted in order to determine the impact computer games had on the cognitive performance. Study 1 evaluated a measure of cognition, which incorporates aspects of short-term working memory, visual attention, mathematical decision making, and auditory perception. Study 2 measured the cognitive performance between those who did not play video games versus those who played either a violent or non-violent video game. Results from Study 1 indicate participants needed approximately four trials to reach asymptotic performance on the cognitive measure. Results of Study 2 showed that participants who did not play any video game did not have a change in their cognitive performance, while those who played either a violent or non-violent video game had an increase in their cognitive performance.     

The gorilla in the room: The impacts of video-game play on visual attention

Early studies of visual attention noted a phenomenon termed ‘inattention blindness’ – the inability of participants to see clear stimuli enter the visual field when attending to something else in that field – and sought to expand the understanding of the phenomenon (,  and ). Other research has focused on the changes to the human brain and cognitive functions as a result of video game play, both in positive and negative contexts (Howard-Jones, Ott, van Leeuwen, and De Smedt (2010)). This quasi-experimental study sought to corroborate some of the findings that tie together these seemingly disparate lines of research, adapting the methodology of the most cited inattention blindness experiment (Simons & Chabris, 1999).     

Personalized messages in a brewery educational simulation: Is the personalization principle less robust than previously thought?

The personalization principle, one of the design principles of multimedia learning, states that people learn better from multimedia presentations when instructions are in a conversational style rather than a formal style, possibly due to learners' increased interest. This principle was shown to be robust in short interventions that could be completed within minutes or a few dozen minutes; however, complex digital simulations and games that support the acquisition of complex mental models usually take longer to complete. In this study, we investigate the personalization principle in a new context: in an interactive simulation on the topic of beer brewing, which lasts 2–3 h. Instructions were presented in the Czech language, either in a personalized style, where learners were addressed conversationally by “their grandpa, an owner of the family brewery,” or in a non-personalized, more formal style without the grandpa. In Experiment 1, 26 college students, who interacted with both simulation versions, expressed on average a preference for the personalized version of the simulation. However, some of them worried that personalization could distract them. In Experiment 2 with a between-subject design, the knowledge of 75 predominantly college students was tested by means of retention and transfer tests immediately after completing the simulation and also a month later. Contrary to most previous works, our results showed no difference between the personalized and non-personalized groups in learning achievement, despite the fact that learners who received the personalized treatment voluntarily spent about 20% more time on the simulation. We also applied various measures of the learner's affective state, including Flow Short Scale and PANAS, but – again – no between-group differences were observed. These results indicate that personalization is not always beneficial to learning, which raises important questions for future research. Additional findings suggest that the simulation, no matter the treatment type, was most beneficial to learners with high mathematical abilities and who play computer games frequently, and also to those who liked the simulation more.     

What makes good games go viral? The role of technology use,efficacy, emotion and enjoyment in players’ decision to share a prosocial digital game

Serious digital games may be an effective tool for prosocial message dissemination because they offer technology and experiences that encourage players to share them with others, and spread virally. But little is known about the factors that predict players’ willingness to share games with others in their social network. This panel study explores how several factors, including sharing technology use, emotional responses, and game enjoyment, contribute to players’ decision to share the game Darfur is Dying, with others. College students played the game and completed questionnaires that assessed whether they had shared the games at two different time points: during game play and after game play. Positive emotions predicted sharing while students played the game, but negative emotions predicted whether the game was shared after initial game play. Game enjoyment predicted players’ intentions to share the game, but it did not predict actual sharing behavior. Neither players’ general use of sharing technologies nor their satisfaction related to sharing digital content predicted sharing intentions or behavior. These findings have implications for the study of viral social marketing campaigns, and serious game design and theory.     

Learning from entertaining online video clips? Enjoyment and appreciation and their differential relationships with knowledge and behavioral intentions

Based on assumptions from entertainment theory, an online-study (N = 419) was conducted to investigate the differential relationships between enjoyment and appreciation of a video clip that dealt with the features of natural gas as fuel for cars, objective and subjective knowledge about the content of that clip, and behavioral intentions of dealing with the topic of natural gas. Structural equation modeling revealed that enjoyment was directly positively related to objective and subjective knowledge. However, objective knowledge did not predict and subjective knowledge was only weakly associated with behavioral intentions. Appreciation, in contrast, was directly negatively related to knowledge acquisition and not related to subjective knowledge, but was the best predictor for behavioral intentions. These results point to the distinct processes and relationships of different entertainment experiences. Implications for entertainment–education and online video portals are discussed.

Optically based direct manipulation for augmented reality

Augmented reality (AR) constitutes a very powerful three-dimensional user interface for many “hands-on” application scenarios. To fully exploit the AR paradigm, the computer must not only augment the real world, but also accept feedback from it. In this paper, we present an optical approach for collecting such feedback by analyzing video sequences to track users and the objects they work with. Our system can be set up in any room after quickly placing a few known optical targets in the scene. We present two demonstration scenarios to illustrate the overall concept and potential of our approach and then discuss the research issues involved.     

The effects of video game realism on attention, retention and aggressive outcomes

This study used a between subjects, post-test only design to test the effects of video game realism (Doom 1 vs. Doom 3) and a control condition on attention, retention and aggressive outcomes. Overall, those who played Doom 3 perceived it as significantly more realistic than those who played Doom 1, thus providing validity for the manipulation. Next, those who played Doom 3 were significantly more attentive and experienced more presence than those who played Doom 1. Furthermore, playing either Doom game resulted in more aggression than playing no game and physically aggressive intentions were higher among those who played Doom 3 as compared to those who played Doom 1. Lastly, we tested for any possible interaction between realism and the attention and retention subfunctions on production and we found that, compared to the other players, those who experienced greater identification among those playing Doom 3 had higher verbal aggression. For physical aggression, those who played Doom 3 and experienced more attention and greater identification had higher aggression scores than those in the other conditions.     

Does ease-of-use contributes to the perception of enjoyment? A case of gamification in e-banking

The success of online games encouraged the development of gamification software in e-banking. Beside the growing trend of gamification, it is important understand how bank customers face the gamified applications, particularly as enjoyment and ease-of-use. To assess the determinants that influence the adoption of gamification in e-banking, we developed a research to propose a conceptual model that illustrates the adoption of gamified business applications by bank customers, in e-banking context. We conducted two quantitative studies (A and B) to understand how bank customers represent a gamified business software and its changes (or improvements) over time. Study A was performed in 2012 (N = 183), and study B in 2015 (N = 219). Online bank customers were invited to rate the importance of variables related to: socialness, ease-of-use, usefulness, enjoyment and intention to use e-banking systems with game features and social cues. The results show that ease-of-use and enjoyment are interrelated, and both have influence in e-banking usage. This study present theoretical ground of the conceptual model, and discuss two empirical studies, aiming to analyse the ease-of-use and enjoyment influence on bank customers. These findings will contribute directly to explain of adoption hedonic business software in e-banking.     

Social gaming,lonely life? The impact of digital game play on adolescents’ social circles

In recent years, there have been rising concerns about the impact of online video game play on users’ socialization, particularly among adolescent players. The current study addresses one of these concerns and evaluates the potential impact of social displacement on the size and quality of users’ social circles due to video game play. Using a representative sample of adolescent players, the results provide support for the emergence of social displacement effects. Increased social online video game play, but not social offline video game play, was found to correspond with smaller, and lower quality, offline social circles. However, further research is needed to assess the impact of these declines on everyday socialization, such its potential negative influence on the development and maintenance of social skills.
