Situational factors shape moral judgements in the trolley dilemma in Eastern, Southern and Western countries in a culturally diverse sample.

The study of moral judgements often centres on moral dilemmas in which options consistent with deontological perspectives (that is, emphasizing rules, individual rights and duties) are in conflict with options consistent with utilitarian judgements (that is, following the greater good based on consequences). Greene et al. (2009) showed that psychological and situational factors (for example, the intent of the agent or the presence of physical contact between the agent and the victim) can play an important role in moral dilemma judgements (for example, the trolley problem).

Dynamics in charity donation decisions: Insights from a large longitudinal data set.

Despite the vast body of research on charitable giving and its drivers, no research has investigated the longitudinal dynamics of individual donation decisions. We analyzed unique data with nearly 300,000 real donation decisions made by more than 20,000 individuals for a period of 10 months. Each decision entailed a choice of what to do with money received for completing a survey (on average, €0.

The Moral Self-Image Scale: Measuring and Understanding the Malleability of the Moral Self.

Recent ethical decision-making models suggest that individuals' own view of their morality is malleable rather than static, responding to their (im)moral actions and reflections about the world around them. Yet no construct currently exists to represent the malleable state of a person's moral self-image (MSI). In this investigation, we define this construct, as well as develop a scale to measure it.

Brain activity in fairness consideration during asset distribution: does the initial ownership play a role?

Previous behavioral studies have shown that initial ownership influences individuals' fairness consideration and other-regarding behavior. However, it is not entirely clear whether initial ownership influences the brain activity when a recipient evaluates the fairness of asset distribution. In this study, we randomly assigned the bargaining property (monetary reward) to either the allocator or the recipient in the ultimatum game and let participants of the study, acting as recipients, receive either disadvantageous unequal, equal, or advantageous unequal offers from allocators while the event-related potentials (ERPs) were recorded.

Social Comparison Affects Brain Responses to Fairness in Asset Division: An ERP Study with the Ultimatum Game.

Previous studies have shown that social comparison influences individual's fairness consideration and other-regarding behavior. However, it is not clear how social comparison affects the brain activity in evaluating fairness during asset distribution. In this study, participants, acting as recipients in the ultimatum game, were informed not only of offers to themselves but also of the average amount of offers in other allocator-recipient dyads.

Social distance modulates recipient's fairness consideration in the dictator game: an ERP study.

Previous research showed that social distance (e.g., being friends or strangers) influences people's fairness consideration and other-regarding behavior.

Initial ownership in bargaining: introducing the giving, splitting, and taking ultimatum bargaining game.

In three experiments, the authors studied the role of initial ownership of property in bargaining behavior. For this purpose, they created three new variations of the Ultimatum Bargaining Game (UBG): giving, splitting, and taking UBGs. On the basis of insights of loss aversion and the do-no-harm principle, the authors predicted and found that allocations to the recipient were highest in the taking UBG and lowest in the giving UBG.
