Counterfactual comparison modulates fairness consideration in the mini‐ultimatum game: An event‐related potentials study

Existing literature on the mini‐ultimatum game indicates that counterfactual comparison between chosen and unchosen alternatives is of great importance for individual's fairness consideration. However, it is still unclear how counterfactual comparison influences the electrophysiological responses to unfair chosen offers. In conjunction with event‐related potentials’ (ERPs) technique, the current study aimed to explore the issue by employing a modified version of the mini‐ultimatum game where a fixed set of two alternatives (unfair offer vs. fair alternative, unfair vs. hyperfair alternative, unfair offer vs. hyperunfair alternative) was presented before the chosen offer. The behavioral results showed that participants were more likely to accept unfair chosen offers when the unchosen alternative was hyperunfair than when the unchosen alternative was fair or hyperfair. The ERPs results showed that the feedback‐related negativity (FRN) elicited by unfair chosen offers was insensitive to the type of unchosen alternative when correcting for possible overlap with other components. In contrast, unfair chosen offers elicited larger P300 amplitudes when the unchosen alternative was hyperunfair than when the unchosen alternative was fair or hyperfair. These findings suggest that counterfactual comparison may take effect at later stages of fairness consideration as reflected by the P300.     

Public concerns about violent video games are moral concerns—How moral threat can make pacifists susceptible to scientific and political claims against violent video games

Public discussions about the harmfulness of violent media are often held in the aftermath of violent felony. At the same time, we know little about whether and how experiencing real‐life violence impacts the way laypersons perceive and evaluate debates about virtual violence. In Study 1, we provided data indicating that both real‐life violence and violent video games are perceived as morally threatening by people who regard nonviolence to be an important moral value (i.e., pacifists). In Study 2, we hypothesized and found that when pacifists perceive threat from the presence of real‐life violence, they are especially susceptible to scientific and political claims indicating that violent video games are harmful. Our findings are in line with the value protection model and research on the psychological consequences of threat. Implications of the present findings are discussed with regard to a better understanding of the violent video games debate in the general public.     

Are some video games associated with more life interference and psychopathology than others? Comparing massively multiplayer online role‐playing games with other forms of video game

Massively multiplayer online role‐playing games (MMORPGs) are a type of video game that is considered to have particular potential to be associated with life interference and psychopathology when played frequently and intensively. This study sought to compare players of MMORPGs with players of other types of video game in terms of problematic use, life interference, and levels of psychopathology. An international sample of 1,945 video game players completed a series of questionnaires online. While MMORPG players reported increased rates of problematic use and life interference compared with non‐MMORPG players, there were no differences in levels of psychopathology. Differences between MMORPG players and non‐MMORPG players appeared to be associated with the increased amounts of time that MMORPG players played for: The amount of time spent playing appeared to mediate the relationships between type of game played and each of the problematic use and life interference variables. The implications of these findings are discussed.     

Individualistic attitudes toward attractive rewards in older people: An experimental study using ultimatum games

This study used an ultimatum game to test the hypothesis that older individuals make more selfish offers when bargaining for highly attractive rewards, regardless of the impacts of others' responses on reward size. Both older and younger individuals separately participated in the experiment and made offers as allocators. The effects of four factors (age, certainty of the allocators' own reward depending on the recipient's response, the recipient's response, and type of rewards to be shared) on participants' offers and expectations of recipients' replies were observed. Older participants demanded higher shares for themselves than younger participants, even under the low certainty condition in the highly attractive reward scenario. Particularly in this scenario, older participants increased their portions immediately after receiving rejections. Moreover, they consistently expected the recipients to accept their offers regardless of the proposed distribution amount or bargaining conditions. It was implied that the high attractiveness of the rewards made it difficult for older individuals to predict the recipient's view of their proposals and thus contributed to them making selfish proposals.     

Lost in (cyber)space: finding two adolescent boys hiding from their own humanity

This article explores the intense psychological effects of compulsive Internet use, which has become increasingly common among adolescent boys and young men. Two cases are presented and discussed to illustrate some of the psychic distortions around thinking and feeling, as these occurred in the analysis of a mid‐adolescent boy and of another patient in later adolescence. A kind of narcissistic omnipotence grounded in magical thinking appeared to take root in their minds, and it led to an avoidant pattern in relationships because of such strong wishes for both distance and control. A short review of the conceptual origins of magical thinking underscores its continued relevance because so many now engage with the Internet. In addition, Anzieu's idea of the ‘skin ego’ is applied to the clinical case material to provide a theoretical framework for the developmental challenges that can appear in adolescent boys who seek to use the Internet as a form of psychic container. Emerging problems that immersion in the Internet might bring into our practices, for example the depleting effects of massive projective identification, are considered and discussed, along with the obvious ways in which using the Internet can be beneficial for connecting with others, for creating new platforms of expression, and for education.     

The effects of exergaming on physical activity among inactive children in a physical education classroom

Childhood obesity, which is due in part to lack of physical activity, is a serious concern that requires the attention of the behavioral community. Although excessive video game play has been noted in the literature as a contributor to childhood obesity, newer video gaming technology, called exergaming, has been designed to capitalize on the reinforcing effects of video games to increase physical activity in children. This study evaluated the effects of exergaming on physical activity among 4 inactive children in a physical education (PE) classroom. Results showed that exergaming produced substantially more minutes of physical activity and more minutes of opportunity to engage in physical activity than did the standard PE program. In addition, exergaming was socially acceptable to both the students and the PE teacher. Exergaming appears to hold promise as a method for increasing physical activity among inactive children and might be a possible intervention for childhood obesity.     

Estimation and visualization of confusability matrices from adaptive measurement data

We present a simple but effective method based on Luce’s choice axiom [Luce, R.D. (1959). Individual choice behavior: A theoretical analysis. New York: John Wiley & Sons] for consistent estimation of the pairwise confusabilities of items in a multiple-choice recognition task with arbitrarily chosen choice-sets. The method combines the exact (non-asymptotic) Bayesian way of assessing uncertainty with the unbiasedness emphasized in the classical frequentist approach.We apply the method to data collected using an adaptive computer game designed for prevention of reading disability. A player’s estimated confusability of phonemes (or more accurately, phoneme-grapheme connections) and larger units of language is visualized in an easily understood way with color cues and explicit indication of the accuracy of the estimates. Visualization of learning-related changes in the player’s performance is considered.The empirical validity of the choice axiom is evaluated using the game data itself. The axiom appears to hold reasonably well although a small systematic violation is observable for the smallest choice-set sizes.     

A Bayesian-optimal principle for learner-friendly adaptation in learning games

Adaptive learning games should provide opportunities for the student to learn as well as motivate playing until goals have been reached. In this paper, we give a mathematically rigorous treatment of the problem in the framework of Bayesian decision theory. To quantify the opportunities for learning, we assume that the learning tasks that yield the most information about the current skills of the student, while being desirable for measurement in their own right, would also be among those that are efficient for learning. Indeed, optimization of the expected information gain appears to naturally avoid tasks that are exceedingly demanding or exceedingly easy as their results are predictable and thus uninformative. Still, tasks that are efficient for learning may be experienced as too challenging, and the resulting failures can lower motivation. Therefore, in addition to quantifying the expected informational benefit for learning of any prospective task to be presented next, we also model the expected motivational cost of its presentation, measured simply as the estimated probability of failure in our example model. We propose a “learner-friendly” adaptation algorithm that chooses the learning tasks by optimizing the expected benefit divided by the expected cost. We apply this algorithm to a Rasch-like student model implemented within a real-world application and present initial results of a pilot experiment.     

Playing the game the child allots

This paper explores the relationship between play and interpretative verbalization in child analysis. Through examination of a clinical case, the paper distinguishes between two different modes of interpretative interventions in play. It is the contention of the paper that the analyst’s capacity to tolerate tension and respond to the roles the child assigns him widens the area of play, facilitating a space for thinking through. Interpretation is formulated in two distinct ways: (a) interpreting from the context of the roles the analyst assumes within play, respecting the games and facilitating the patient’s understanding; (b) interpreting at a distance from play, on the one hand distinguishing the area of play, and on the other hand analyzing that which occurs verbally and non‐verbally.
