Moral judgments are produced through the coordinated interaction of multiple neural systems, each of which relies on a characteristic set of neurotransmitters. Genes that produce or regulate these neurotransmitters may have distinctive influences on moral judgment. Two studies examined potential genetic influences on moral judgment using dilemmas that reliably elicit competing automatic and con...

This study compares the neural substrate of moral decision making processes between Korean and American participants. By comparison with Americans, Korean participants showed increased activity in the right putamen associated with socio-intuitive processes and right superior frontal gyrus associated with cognitive control processes under a moral-personal condition, and in the right postcentral ...

Previous studies found that the likelihood of subjects to choose a deontological judgment (e.g., allowing harm) or a consequentialist judgment (e.g., doing harm) varied across different moral dilemmas. The present paper explored if the variation can be explained by the differentiation of the perceived outcome probabilities. We generated moral dilemmas that were similar to the classical trolley ...

Studied the relationship between social motivation and approaches to moral decision making, and also the emotions people experience in real life moral dilemmas. 44 students were interviewed about a moral dilemma that they had faced in the past. Social motivation was measured with Emmons’ (1989) idiographic personal strivings method. Intimacy motivation was related to a preference for making dec...

Moral dilemmas are used to study the situations in which there is a conflict between two moral rules: e.g. is it permissible to kill one person in order to save more people. In standard moral dilemmas the protagonist is a human. However, the recent progress in robotics leads to the question of how artificial cognitive agents should act in situations involving moral dilemmas. Here, we study mora...

Humans daily face social situations involving conflicts between competing moral decision. Despite a substantial amount of studies published over the past 10 years, the respective role of emotions and reason, their possible interaction, and their behavioural expression during moral evaluation remains an unresolved issue. A dualistic approach to moral evaluation proposes that the right dorsolater...

Utilitarian versus deontological inclinations have been studied extensively in the field of moral psychology. However, the field has been lacking a thorough psychometric evaluation of the most commonly used measures. In this paper, we examine the factorial structure of an often used set of 12 moral dilemmas purportedly measuring utilitarian/deontological moral inclinations. We ran three differe...
