Steady steps versus sudden shifts: Cooperation in (a)symmetric linear and step-level social dilemmas
Are groups of people better able to minimize a collective loss if there is a collective target that must be reached or if every small contribution helps? In this paper we investigate whether cooperation in social dilemmas can be increased by structuring the problem as a step-level social dilemma rather than a linear social dilemma and whether cooperation can be increased by manipulating endowment asymmetry between individuals. In two laboratory experiments using 'Public Bad' games, we found that that individuals defect less and are better able to minimize collective and personal costs in a step-level social dilemma than in a linear social dilemma. We found that the level of cooperation is not affected by an ambiguous threshold: even when participants cannot be sure about the optimal cooperation level, cooperation remains high in the step-level social dilemmas. We find mixed results for the effect of asymmetry on cooperation. These results imply that presenting social dilemmas as step-level games and reducing asymmetry can help solve environmental dilemmas in the long term

In this paper we investigate whether cooperation in social dilemmas can be increased by structuring the problem as a step-level social dilemma rather than a linear social dilemma and whether cooperation can be increased by manipulating endowment asymmetry between individuals. In two laboratory experiments using âPublic Badâ games, we found that that individuals defect less and are better able to minimize collective and personal costs in a step-level social dilemma than in a linear social dilemma. We found that the level of cooperation is not affected by an ambiguous threshold: even when participants cannot be sure about the optimal cooperation level, cooperation remains high in the step-level social dilemmas.

Measuring social value orientation
Narrow self-interest is often used as a simplifying assumption when studying people making decisions in social contexts. Nonetheless, people exhibit a wide range of different motivations when choosing unilaterally among interdependent outcomes. Measuring the magnitude of the concern people have for others, sometimes called Social Value Orientation (SVO), has been an interest of many social scientists for decades and several different measurement methods have been developed so far. Here we introduce a new measure of SVO that has several advantages over existent methods. A detailed description of the new measurement method is presented, along with norming data that provide evidence of its solid psychometric properties. We conclude with a brief discussion of the research streams that would benefit from a more sensitive and higher resolution measure of SVO, and extend an invitation to others to use this new measure which is freely available.Social Value Orientation (SVO), social preferences, narrow self-interest, measurement methods, individual differences.
Distance makes the mind grow broader: an overview of psychological distance studies in the environmental and health domains
Environmental and health issues are two of the most pressing issues society faces today. People often view both environmental and health issues as psychologically distant: they believe that the problems will occur in the future, to other people, in other places and that the exact outcomes are uncertain. This paper provides an overview of studies that have investigated how the different psychological distance dimensions (viz., temporal, spatial, social and hypothetical) influence perceptions, intentions, and decision making in the environmental and health domains. This overview suggests that psychological distance indeed matters in both domains. There are indications that threat perceptions are mostly heightened when communicated or perceived as being psychologically close. However, the studies also show that a mere increase in perceived threat does not necessarily alter intentions or behavior. Moreover, with regard to the effects of psychological distance, there are neither clear differences between the environmental and the health domain nor between the four psychological distance dimensions. We discuss possible moderators that may explain the range of findings. Finally, we conclude with discussing the current stance of the literature and discuss specific research topics that are yet to be studied. As environmental and health behavior involve more than just one decision or one behavior, we suggest, for example, that future studies should investigate how psychological distance influences not only the target behavior, but related behavior as well
DISTANCE MAKES THE MIND GROW BROADER: AN OVERVIEW OF PSYCHOLOGICAL DISTANCE STUDIES IN THE ENVIRONMENTAL AND HEALTH DOMAINS
Environmental and health issues are two of the most pressing issues society faces today. People often view both environmental
and health issues as psychologically distant: they believe that the problems will occur in the future, to other people, in other places and that
the exact outcomes are uncertain. This paper provides an overview of studies that have investigated how the different psychological distance
dimensions (viz., temporal, spatial, social and hypothetical) influence perceptions, intentions, and decision making in the environmental
and health domains. This overview suggests that psychological distance indeed matters in both domains. There are indications that threat
perceptions are mostly heightened when communicated or perceived as being psychologically close. However, the studies also show that a
mere increase in perceived threat does not necessarily alter intentions or behavior. Moreover, with regard to the effects of psychological
distance, there are neither clear differences between the environmental and the health domain nor between the four psychological distance
dimensions. We discuss possible moderators that may explain the range of findings. Finally, we conclude with discussing the current stance
of the literature and discuss specific research topics that are yet to be studied. As environmental and health behavior involve more than just
one decision or one behavior, we suggest, for example, that future studies should investigate how psychological distance influences not only
the target behavior, but related behavior as well
The Decision Making Individual Differences Inventory and guidelines for the study of individual differences in judgment and decision-making research
Individual differences in decision making are a topic of longstanding interest, but often yield inconsistent and contradictory results. After providing an overview of individual difference measures that have commonly been used in judgment and decision-making (JDM) research, we suggest that our understanding of individual difference effects in JDM may be improved by amending our approach to studying them. We propose four recommendations for improving the pursuit of individual differences in JDM research: a more systematic approach; more theory-driven selection of measures; a reduced emphasis on main effects in favor of interactions between individual differences and decision features, situational factors, and other individual differences; and more extensive communication of results (whether significant or null, published or unpublished). As a first step, we offer our database---the Decision Making Individual Differences Inventory (DMIDI; html://www.dmidi.net), a free, public resource that categorizes and describes the most common individual difference measures used in JDM research
