In the present research we analyze the interrelations of spatial distance and efficaciousness in helping needy others, and we investigate how these factors affect our judgments of moral helping obligations. The main question is under which conditions the location of an agent’s means of helping relative to a victim is regarded as morally relevant. We develop a new experimental design that allows...

Evidence from studies in international relations, the politics of reform, collective action and price competition suggests that economic agents in social dilemma situations cooperate more to avoid losses than in the pursuit of gains. To test whether the prospect of losses can induce cooperation, we let experimental subjects play the traveler’s dilemma in the gain and loss domain. Subjects coope...

Using a computational testbed, we theoretically predict and experimentally show that in the minimum effort coordination game, as the cost of effort increases, 1) the game converges to lower effort levels, 2) the convergence speed increases, and 3) the average payoff is not monotonically decreasing. In fact, the average profit is an U-shaped curve as a function of cost. Therefore, contrary to th...

In undergoing this life, many people always try to do and get the best. New knowledge, experience, lesson, and everything that can improve the life will be done. However, many people sometimes feel confused to get those things. Feeling the limited of experience and sources to be better is one of the lacks to own. However, there is a very simple thing that can be done. This is what your teacher ...

The authors examined whether different levels of sense of humor would influence respondents’ ratings about a potentially desirable partner. The authors used vignettes to predict that the targets who possessed a good sense of humor would receive significantly higher ratings in measures of attractiveness and suitability as a long-term partner than would those who possessed an average or no sense ...

Interestingly, practical experiment designs for engineers and scientists that you really wait for now is coming. It's significant to wait for the representative and beneficial books to read. Every book that is provided in better way and utterance will be expected by many peoples. Even you are a good reader or not, feeling to read this book will always appear when you find it. But, when you feel...

Bracketing is a mental procedure about how people deal with multiple tasks. If a decision maker handles all the tasks at the same time, it is called broad bracketing. If she handles the tasks separately, e.g., one or a few tasks each time, it is called narrow bracketing. This paper experimentally investigates the effect of broad versus narrow bracketing in the context of a mini-trust game. The ...

Virtual home theatre systems provide an efficient means of multichannel sound reproduction with two loudspeakers. Six commercial and academically developed systems have been collected and subjectively evaluated under controlled conditions against discrete 5-channel reproduction. Tests have been carried out in two test rooms. The experimental design and the detailed analysis of results are prese...
