Effects of prosocial video games on prosocial behavior.
Previous research has documented that playing violent video games has various negative effects on social behavior in that it causes an increase in aggressive behavior and a decrease in prosocial behavior. In contrast, there has been much less evidence on the effects of prosocial video games. In the present research, 4 experiments examined the hypothesis… (More)
Coping with terrorism: the impact of increased salience of terrorism on mood and self-efficacy of intrinsically religious and nonreligious people.
It was hypothesized that intrinsic religiousness helps to cope with increased salience of terrorism. Intrinsically religious and non-religious participants were told that it is highly probable or highly improbable, respectively, that terrorist attacks will occur in Germany. High probability of terrorism only negatively affected the mood of non-religious… (More)
Playing prosocial video games increases the accessibility of prosocial thoughts.
Past research has provided abundant evidence that playing violent video games increases aggressive tendencies. In contrast, evidence on possible positive effects of video game exposure on prosocial tendencies has been relatively sparse. The present research tested and found support for the hypothesis that exposure to prosocial video games increases the… (More)
The bystander-effect: a meta-analytic review on bystander intervention in dangerous and non-dangerous emergencies.
Research on bystander intervention has produced a great number of studies showing that the presence of other people in a critical situation reduces the likelihood that an individual will help. As the last systematic review of bystander research was published in 1981 and was not a quantitative meta-analysis in the modern sense, the present meta-analysis… (More)
Preference-consistent evaluation of information in the hidden profile paradigm: beyond group-level explanations for the dominance of shared information in group decisions.
Common explanations for the failure of groups to solve so-called hidden profiles focus on group processes, namely insufficient discussion of unshared information and premature consensus on a suboptimal alternative. As 2 experiments show, even in the absence of such group processes, hidden profiles are hardly ever solved. In Experiment 1, participants first… (More)
Red, rank, and romance in women viewing men.
In many nonhuman species of vertebrates, females are attracted to red on male conspecifics. Red is also a signal of male status in many nonhuman vertebrate species, and females show a mating preference for high-status males. These red-attraction and red-status links have been found even when red is displayed on males artificially. In the present research,… (More)
Information sampling and group decision making: the effects of an advocacy decision procedure and task experience.
Group discussions tend to focus on information that was previously known by all members (shared information) rather than information known by only 1 member (unshared information). If the shared information implies a suboptimal alternative, this sampling bias is associated with inaccurate group decisions. The present study examines the impact of 2 factors on… (More)
The effects of risk-glorifying media exposure on risk-positive cognitions, emotions, and behaviors: a meta-analytic review.
In recent years, there has been a surge in the quantity of media content that glorifies risk-taking behavior, such as risky driving, extreme sports, or binge drinking. The authors conducted a meta-analysis involving more than 80,000 participants and 105 independent effect sizes to examine whether exposure to such media depictions increased their recipients'… (More)
Highlighting relatedness promotes prosocial motives and behavior.
According to self-determination theory, people have three basic psychological needs: relatedness, competence, and autonomy. Of these, the authors reasoned that relatedness need satisfaction is particularly important for promoting prosocial behavior because of the increased sense of connectedness to others that this engenders. In Experiment 1, the authors… (More)
