Emotion and Adaptation

Статья посвящена вопросам влияния власти на поведение человека. Авторы рассматривают данные различных источников, в которых увеличение власти связывается с напористостью, а ее уменьшение - с подавленностью. Конкретно, власть ассоциируется с: а) позитивным аффектом; б) вниманием к вознаграждению и к свойствам других, удовлетворяющим личные цели; в) автоматической переработкой информации и резкими суждениями; г) расторможенным социальным поведением. Уменьшение власти, напротив, ассоциируется с: а) негативным аффектом; б) вниманием к угрозам и наказаниям, к интересам других и к тем характеристикам я, которые отвечают целям других; в) контролируемой переработкой информации и совещательным типом рассуждений; г) подавленным социальным поведением. Обсуждаются также последствия этих паттернов поведения, связанных с властью, и потенциальные модераторы.

Power, approach, and inhibition. Власть, напористость и подавленность

This paper examines the literature on computer games and serious games in regard to the potential positive impacts of gaming on users aged 14 years or above, especially with respect to learning, skill enhancement and engagement. Search terms identified 129 papers reporting empirical evidence about the impacts and outcomes of computer games and serious games with respect to learning and engagement and a multidimensional approach to categorizing games was developed. The findings revealed that playing computer games is linked to a range of perceptual, cognitive, behavioural, affective and motivational impacts and outcomes. The most frequently occurring outcomes and impacts were knowledge acquisition/content understanding and affective and motivational outcomes. The range of indicators and measures used in the included papers are discussed, together with methodological limitations and recommendations for further work in this area.

A systematic literature review of empirical evidence on computer games and serious games

Even though considerable attention has been given to the polarity of words (positive and negative) and the creation of large polarity lexicons, research in emotion analysis has had to rely on limited and small emotion lexicons. In this paper, we show how the combined strength and wisdom of the crowds can be used to generate a large, high-quality, word–emotion and word–polarity association lexicon quickly and inexpensively. We enumerate the challenges in emotion annotation in a crowdsourcing scenario and propose solutions to address them. Most notably, in addition to questions about emotions associated with terms, we show how the inclusion of a word choice question can discourage malicious data entry, help to identify instances where the annotator may not be familiar with the target term (allowing us to reject such annotations), and help to obtain annotations at sense level (rather than at word level). We conducted experiments on how to formulate the emotion-annotation questions, and show that asking if a term is associated with an emotion leads to markedly higher interannotator agreement than that obtained by asking if a term evokes an emotion.

Crowdsourcing a word–emotion association lexicon

The authors examined whether the nature of the opponent (computer, friend, or stranger) influences spatial presence, emotional responses, and threat and challenge appraisals when playing video games. In a within-subjects design, participants played two different video games against a computer, a friend, and a stranger. In addition to self-report ratings, cardiac interbeat intervals (IBIs) and facial electromyography (EMG) were measured to index physiological arousal and emotional valence. When compared to playing against a computer, playing against another human elicited higher spatial presence, engagement, anticipated threat, post-game challenge appraisals, and physiological arousal, as well as more positively valenced emotional responses. In addition, playing against a friend elicited greater spatial presence, engagement, and self-reported and physiological arousal, as well as more positively valenced facial EMG responses, compared to playing against a stranger. The nature of the opponent influences spatial presence when playing video games, possibly through the mediating influence on arousal and attentional processes.

Spatial Presence and Emotions during Video Game Playing: Does It Matter with Whom You Play?

This article reviews the psychophysiological method in game research. Psychophysiological measurements provide an objective, continuous, real-time, noninvasive, precise and sensitive way to assess the game experience. However, the best results require controlled experiments with careful monitoring of variables, large enough sample sizes and expertise in electrical signal processing. We briefly explain the theory behind the method and present the most useful measures: electromyography (EMG), electrodermal activity (EDA), electroencephalography (EEG) and cardiac measures. We review previous studies that have used psychophysiological measures in game research and illustrate some future directions. Our article covers several research lines using the psychophysiological method in game studies, and offers a comprehensive list of references for those interested in the field.

A review of the use of psychophysiological methods in game research

We examined emotional valence- and arousal-related phasic psychophysiological responses to different video game events among 36 young adults who played Super Monkey Ball 2 (Sega Corporation, Tokyo, Japan). Event-related changes in zygomaticus major, corrugator supercilii, and orbicularis oculi electromyographic activity, skin conductance level, and cardiac interbeat intervals were recorded. Instantaneous game events elicited reliable psychophysiological responses indexing valence and arousal. A largely linear, positive dose-response relationship between rewards obtained in the game and phasic increases in arousal was revealed. The valence of the emotional response varied as a function of the player's active participation (active coping). In addition, not only positive events, but also some putatively negative events elicited positively valenced arousal. The findings extend our understanding of the phasic changes in the emotional state during video games and a dynamic flow of events and action and may have...

Phasic Emotional Reactions to Video Game Events: A Psychophysiological Investigation

We investigated the emotional response patterns and sense of presence elicited by video games with different characteristics (i.e., Tetris, Super Monkey Ball 2, Monkey Bowling 2, and James Bond 007: NightFire) among 37 undergraduates. We also examined the moderating influence of the sensation seeking and self-forgetfulness traits on the responses. Participants self-reported their emotional responses, defined in terms of joy, pleasant relaxation, anger, fear, and depressed feeling, and sense of presence. The results showed that games with different characteristics elicit differential emotional response patterns, and the engagement elicited by the games varies as a function of the Sensation Seeking trait of the player. Measuring emotional response patterns may have practical implications for game design, given that they give information on the game characteristics that maximize entertainment and pleasure, and may potentially be used in pre-testing different versions of the games.

Emotional response patterns and sense of presence during video games: potential criterion variables for game design

Meditation in general and mindfulness in particular have been shown to be useful techniques in the treatment of a plethora of ailments, yet they can be challenging for novices. We present RelaWorld: a neuroadaptive virtual reality meditation system that combines virtual reality with neurofeedback to provide a tool that is easy for novices to use yet provides added value even for experienced meditators. Using a head-mounted display, users can levitate in a virtual world by doing meditation exercises. The system measures users' brain activity in real time via EEG and calculates estimates for the level of conCentration and relaxation. These values are then mapped into the virtual reality. In a user study of 43 subjects, we were able to show that the RelaWorld system elicits deeper relaxation, feeling of presence and a deeper level of meditation when compared to a similar setup without head-mounted display or neurofeedback.
