This dissertation examines the psychology of moral judgment and its implications for normative ethics and metaethics. Recent empirical findings in moral psychology, such as the impact of emotions, intuitions, and situational factors on moral judgments, have sparked a debate about whether ordinary moral judgments are systematically error-prone. Some philosophers, such as Peter Singer and Joshua Greene, argue that these findings challenge the reliability of moral intuitions and support more "reasoned", consequentialist approaches over deontological ones. The first part of the dissertation (...) reviews these provocative findings and the philosophical reactions to them, which often invoke the notion of 'moral relevance' - the idea that some factors shaping moral judgments are morally irrelevant. The second part develops a psychological account of moral relevance, drawing on theories of the moral domain, the role of emotions, and models of moral cognition. This account reveals the complex interplay of intuitive and reasoned processes in generating impressions of moral relevance. The final part reevaluates the philosophical discussions in light of this psychological understanding. It contends that the evolutionary background of moral intuitions does not necessarily render them inadequate, and that both deontological and consequentialist judgments likely depend on evolved intuitions to a significant degree. Furthermore, the tendency to dismiss certain influences on moral judgment as irrelevant can itself be explained psychologically. Considering the psychological account presented, mind-independent accounts of morality become less plausible. The dissertation concludes that while empirical moral psychology reveals important constraints on normative theorizing, it does not decisively favor consequentialism over deontology. To assess the significance of empirical-scientific findings for ethics, a nuanced understanding of the origins of moral judgments is nevertheless indispensable. (shrink)

What is moral reasoning? For that matter, what is any sort of reasoning? Let me begin by making a few distinctions. First, there is a distinction between reasoning as something that that people do and the abstract structures of proof or “argument” that are the subject matter of formal logic. I will be mainly concerned with reasoning in the first sense, reasoning that people do. Second, there is a distinction between moral reasoning with other people and moral reasoning by and (...) for yourself . Moral reasoning with others may involve discussion with them, bargaining with them, and possibly arguing with them. (shrink)

Drawing from the dual process model of morality and life history theory, the present research examined the role of cognitive and emotional processes as bridges between basic environmental challenges and other-centered moral orientation. In two survey studies, cognitive and emotional processes represented by future-oriented planning and emotional attachment, respectively, or by perspective taking and empathic concern, respectively, positively predicted other-centeredness in prosocial moral reasoning and moral judgment dilemmas based on rationality or intuition. Cognitive processes were more closely related to rational (...) aspects of other-centeredness, whereas the emotional processes were more closely related to the intuitive aspects of other-centeredness. Finally, the cognitive and emotional processes also mediated negative effects of unpredictability, as well as positive effects of individual-level, contest competition on other-centeredness. Overall, these findings support the view that cognitive and emotional processes do not necessarily contradict each other. Rather, they might work in concert to promote other-centeredness in various circumstances and might be attributed to humans’ developmental flexibility in the face of environmental challenges.

In this article I analyze the academic reception of Jonathan Haidt’s seminal article _The emotional dog and its rational tail: A social intuitionist approach to moral judgment_. My thesis is that in the spheres of philosophy and psychology, this article was initially studied within the neurocentric paradigm, which dominated the field of scientific reflection in the fifteen years following its publication. This neurocentric reading established a specific interpretation of the text with several limitations. However, more recently a digital paradigm has (...) emerged and come to prevail in academia, providing a new perspective from which to return to Haidt’s text. Indeed, this approach makes it possible to unravel elements of the famous article that in the neurocentric paradigm went unnoticed by researchers. Moreover, the digital paradigm manages to better integrate Haidt’s seminal article into his later work as a whole. (shrink)

This study aimed at determining B.S. Biology students’ comprehension of the Bioethics principles and conviction schemas towards bioethical issues; as well as at identifying predictors for comprehension of bioethical principles and convictions and creating model constructs of predictors which are fit for the data. One-hundred sixteen Filipino Biology majors were pre and post-tested for comprehension of bioethics principles and convictions towards bioethical issues. Predictors for comprehension and convictions among personal and family background factors, global and primary personality factors, and mental (...) ability were identified through step-wise multiple regression. Constructed path models were tested for goodness of fit using Structural Equation Modeling. Results showed that case study discussion and the bioethics course had positive effects on comprehension of the bioethics principles and on convictions towards bioethical issues. Predictors for comprehension of Bioethics principles before intervention were verbal ability, warmth, and exposure to media. Sex and openness to change were predictors for pre-convictions. Post-conviction predictors were anxiety, self-control, extraversion, liveliness, and perfectionism. Four out of five model constructs were accepted based on model fit criteria. In conclusion, personal factors, i.e., sex and personality factors are contributors in bioethical convictions; not cognitive factors like mental ability or comprehension of Bioethics principles; implying that bioethical convictions are already pre-conceived and that empathy-based experiences may strengthen convictions towards bioethical issues.

This study analyzes cognitive responses to explore a dual processing perspective of ethical judgment formation. Specifically, the study investigates how two factors, judgment task difficulty and moral intensity, influence the extent of deontological and teleological processing and their effects on ethical judgments. A single experiment on 110 undergraduate research participants found that judgment task difficulty affected the extent of deontological and teleological processing. Although moral intensity affected ethical judgments, it did not produce effects on either deontological or teleological cognitive responses. (...) Results did not support the hypotheses that deontological and teleological cognitive responses would mediate the relationships between the experimental factors and ethical judgments. Overall, the results support continued research of factors that affect the nature of information processing in ethical decision situations and the use of cognitive response analysis as a tool for conducting this research.

What role does moral reasoning play in moral judgment? More specifically, what causal role does moral reasoning have in the production of moral judgments? Recently, many philosophers and psychologists have attempted to answer this question by drawing on empirical data. However, these attempts fall short because there has been no sustained attention to the question of what moral reasoning is. This paper addresses this problem, by providing a general account of moral reasoning in terms of a capacity, and suggests how (...) this account of moral reasoning can provide a way forward in current debates.

Rationalism about the psychology of moral judgment holds, among other things, that the justifying moral reasons we have for our judgments are also the causally effective reasons for why we make those judgments. This can be called the ‘effectiveness’-thesis regarding moral reasoning. The theory that best exemplifies the thesis is the traditional conscious reasoning-paradigm. Current empirical moral psychology, however, poses a serious challenge to this thesis: it argues that in fact, emotional reactions are necessary and sufficient to account for moral (...) judgment, and that typically, moral reasoning is a matter of mere confabulation. In this survey, the empirical challenge to this thesis made by the ‘social intuitionist’ model of moral judgment and reasoning is discussed. The model claims that moral reasoning is essentially ineffective and, psychologically speaking, a matter of mere post hoc-rationalizations of cognitively impenetratable gut reactions. Several interpretations of this evidence are discussed and it is shown that there is room for a psychology of moral reasoning that can account for the available empirical evidence and yet does not have to give up the most central elements of a normative picture of moral reasoning.

May interprets the prevalence of non-emotional moral intuitions as indicating support for rationalism. However, research in developmental psychology indicates that the mechanisms underlying these intuitions are not always rational in nature. Specifically, automatic intuitions can emerge passively, through processes such as evolutionary preparedness and enculturation. Although these intuitions are not always emotional, they are not clearly indicative of reason.

Psychologists and philosophers often work hand in hand to investigate many aspects of moral cognition. In this paper, we want to highlight one aspect that to date has been relatively neglected: the stability of moral judgment over time. After explaining why philosophers and psychologists should consider stability and then surveying previous research, we will present the results of an original three-wave longitudinal study. We asked participants to make judgments about the same acts in a series of sacrificial dilemmas three times, (...) 6–8 days apart. In addition to investigating the stability of our participants’ ratings over time, we also explored some potential explanations for instability. To end, we will discuss these and other potential psychological sources of moral stability (or instability) and highlight possible philosophical implications of our findings. (shrink)

While individual differences in the willingness and ability to engage analytic processing have long informed research in reasoning and decision making, the implications of such differences have not yet had a strong influence in other domains of psychological research. We claim that analytic thinking is not limited to problems that have a normative basis and, as an extension of this, predict that individual differences in analytic thinking will be influential in determining beliefs and values. Along with assessments of cognitive ability (...) and style, religious beliefs, and moral values, participants judged the wrongness of acts considered disgusting and conventionally immoral, but that do not violate care- or fairness-based moral principles. Differences in willingness to engage analytic thinking predicted reduced judgements of wrongness, independent of demographics, political ideology, religiosity, and moral values. Further, we show that those who were higher in cognitive ability were less likely to indicate that purity, patriotism, and respect for traditions and authority are important to their moral thinking. These findings are consistent with a “Reflectionist” view that assumes a role for analytic thought in determining substantive, deeply-held human beliefs and values. (shrink)

Although a distinction between moral-personal and moral-impersonal dilemmas (Greene, Sommerville, Nystrom, Darley, & Cohen, 2001 Greene, J. D., Sommerville, R. B., Nystrom, L. E., Darley, J. M. and Cohen, J. D. 2001. An fMRI investigation of emotional engagement in moral judgement. Science, 293: 2105–2108. doi:10.1126/science.1062872.[Crossref], [PubMed], [Web of Science ®], [Google Scholar]) has been widely accepted as an explanation for a difference between the trolley and footbridge dilemmas (Thomson, 1985 Thomson, J. J. 1985. “The trolley problem”. In Ethics: Problems and (...) principles, Edited by: Fischer, J. M. and Ravizza, M. Fort Worth, TX: Harcourt Brace Jovanovich. [Google Scholar]), its psychometric properties remain a mystery. In this study 219 participants completed 62 moral dilemma tasks used in Greene et al. (2001 Greene, J. D., Sommerville, R. B., Nystrom, L. E., Darley, J. M. and Cohen, J. D. 2001. An fMRI investigation of emotional engagement in moral judgement. Science, 293: 2105–2108. doi:10.1126/science.1062872.[Crossref], [PubMed], [Web of Science ®], [Google Scholar]), and the correlation structure among the dilemmas was analysed through factor analysis and structural equation modelling. Findings suggest that, first, moral-personal dilemmas are composed of one factor, indicating that the assumption in Greene et al. (2001 Greene, J. D., Sommerville, R. B., Nystrom, L. E., Darley, J. M. and Cohen, J. D. 2001. An fMRI investigation of emotional engagement in moral judgement. Science, 293: 2105–2108. doi:10.1126/science.1062872.[Crossref], [PubMed], [Web of Science ®], [Google Scholar]) was supported. Second, moral-impersonal dilemmas are explained by two factors that reflect procedural and consequential aspects of decision making. Third, the trolley and footbridge dilemmas fall under the same factor category; therefore the difference between the two dilemmas cannot be attributed to emotional involvement. Additionally, the results of the structural equation modelling suggest that they differ in the engagement of rational processing. (shrink)

The role of reasoning in our moral lives has been increasingly called into question by moral psychology. Not only are intuitions guiding many of our moral judgments and decisions, with reasoning only finding post-hoc rationalizations, but reasoning can sometimes play a negative role, by finding excuses for our moral violations. The observations fit well with the argumentative theory of reasoning (Mercier H, Sperber D, Behav Brain Sci, in press-b), which claims that reasoning evolved to find and evaluate arguments in dialogic (...) contexts. This theory explains the strong confirmation bias that reasoning displays when it produces arguments, which in turn explains its tendency to rationalize our decisions. But this theory also predicts that people should be able to evaluate arguments felicitously and that, as a result, people should reason better in groups, when they are confronted with other people’s arguments. Groups are able to converge on better moral judgments. It is argued that reasoning and argumentation play an important role in our everyday moral lives, and a defense of the value of reasoning for moral change is offered. (shrink)

Recently, a multinomial process tree model was developed to measure an agent’s consequence sensitivity, norm sensitivity, and generalized inaction/action preferences when making moral decisions (CNI model). However, the CNI model presupposed that an agent considersconsequences—norms—generalizedinaction/actionpreferences sequentially, which is untenable based on recent evidence. Besides, the CNI model generates parameters at the group level based on binary categorical data. Hence, theC/N/Iparameters cannot be used for correlation analyses or other conventional research designs. To solve these limitations, we developed the CAN algorithm to (...) computenormandconsequencesensitivities and overallaction/inactionpreferences algebraically in a parallel manner. We re-analyzed the raw data of the original CNI model to test the methodological predictions. Our results demonstrate that: (1) theCparameter is approximately equal between the CNI model and CAN algorithm; (2) theNparameter under the CNI model approximately equalsN/(1 −C) under the CAN algorithm; (3) theIparameter andAparameter are reversed around 0.5 – the larger theIparameter, the more the generalized inactionversusaction preference and the larger theAparameter, the more overall actionversusinaction preference; (4) tests of differences in parameters between groups with the CNI model and CAN algorithm led to almost the same statistical conclusion; (5) parameters from the CAN algorithm can be used for correlational analyses and multiple comparisons, and this is an advantage over the parameters from the CNI model. The theoretical and methodological implications of our study were also discussed. (shrink)

The increasing focus to go beyond assessing cognitive constructs around the globe and in Singapore such as cultural awareness, grit and moral reasoning and the call for schools to prepare students for citizenship the development of corresponding instruments applicable in a larger scale. Given the significance of moral reasoning and its assessment are key elements within the current Singapore Character and Citizenship Education curriculum -syllabus.pdf, 2012), there is room to explore how moral reasoning can be assessed practically in a large-scale (...) setting. Undergirding this exploration requires a review of the epistemology of moral reasoning, corresponding theoretical frameworks, and how they might apply to moral education in Singapore schools. By reviewing perspectives of moral reasoning from relevant literature beyond educational research to business, medical and philosophical domains, this paper aims to propose an operational definition of moral reasoning suitable for use in Singapore schools, and to mitigate possible issues brought about by educators’ disparate or assumed understanding of moral reasoning. This can consequently support the enactment of the CCE curriculum and be applied to the development of assessment instruments suitable for use within Singapore schools and similar contexts. (shrink)

The standard way to test alternative descriptive theories of moral judgment is by asking subjects to evaluate (amongst others) sacrificial dilemmas, where acting classifies as a utilitarian moral judgment and not acting classifies as a deontological moral judgment. Previous research uncovered many situational factors that alter subject’s moral judgments without affecting which type of action utilitarianism or deontology would recommend. This literature review provides a systematic analysis of the experimental literature on the influence of situational factors on moral judgments in (...) sacrificial dilemmas. It analyses 53 articles in detail and reports mean effect sizes, as well as operationalizations, for 36 situational factors that significantly influence moral judgment. Moreover, the review discusses how the impact of situational factors relates to a dual process theory of moral judgment. It supports the view that utilitarian judgments are driven by controlled cognitive processes and shows that the drivers of deontological judgments depend on valence. (shrink)

According to Joshua Greene’s influential dual process model of moral judgment, different modes of processing are associated with distinct moral outputs: automatic processing with deontological judgment, and controlled processing with utilitarian judgment. This paper aims to clarify and assess Greene’s model. I argue that the proposed tie between process and content is based on a misinterpretation of the evidence, and that the supposed evidence for controlled processing in utilitarian judgment is actually likely to reflect generic deliberation which, ironically, is incompatible (...) with a utilitarian outlook. This alternative proposal is further supported by the results of a recent neuroimaging study we have done. (shrink)

Creativity and morality are key attributes that stakeholders demand of organizations. Accordingly, higher education institutions and professional training programs also seek to cultivate these attributes in future leaders. However, research has hitherto shown that, under certain conditions, creativity may conflict with morality. This complicates the development of creative individuals who are also moral. We examined the complex relationship between creativity and moral reasoning with data collected from a group of undergraduate students. By considering the cognitive processes behind creativity and moral (...) reasoning, we propose perspective taking as a moderating factor. Specifically, we found that while creative individuals might not necessarily adopt a lower level of moral reasoning, there was a more nuanced moderating relationship among creativity, perspective taking, and moral reasoning. That is, individuals who were weak in perspective taking tended to adopt a lower level of moral reasoning if they were also creative. Perspective taking was also directly and positively associated with moral reasoning. We explore the implications of our findings for future research and curriculum/program design. (shrink)

Thought experimental methods play a central role in empirical moral psychology. Against the increasingly common interpretation of recent experimental data, I argue that such methods cannot demonstrate that moral intuitions are produced by reflexive computations that are implicit, fast, and largely automatic. I demonstrate, in contrast, that evaluating thought experiments occurs at a near-glacial pace relative to the speed at which reflexive information processing occurs in a human brain. So, these methods allow for more reflective and deliberative processing than has (...) commonly been assumed. However, these methods may still provide insight into some human strategies for navigating unfamiliar moral dilemmas. (shrink)

Recent behavioral experiments, along with imaging experiments and neuropsychological studies appear to support the hypothesis that emotions play a causal or constitutive role in moral judgment. Those who resist this hypothesis tend to suggest that affective mechanisms are better suited to play a modulatory role in moral cognition. But I argue that claims about the role of emotion in moral cognition frame the debate in ways that divert attention away from other plausible hypotheses. I suggest that the available data may (...) be more plausibly explained by appeal to predictive and evaluative mechanisms, which are neither wholly affective nor straightforwardly cognitive. By recognizing this fact, we can begin to see why questions about the role of emotion in moral psychology are likely to be empirically misguided. (shrink)

Joshua Greene’s dual process account contends that deontological moral judgments are the result of intuitions that are automatic, emotional and arational. Deontological intuitions cannot be trusted, Greene argues, because they are arationally acquired and deployed. However, the empirical evidence taken to support this view is methodologically flawed and does not support the utilitarianism-rational and deontology-emotional links that dual process theorists postulate. Instead, the available evidence supports a social domain account of moral development, in which the acquisition of moral intuitions is (...) a rational process. That is, one acquires moral intuitions through repeated exposure to and reasoned engagement with moral information. The deployment of moral intuitions is not arational merely because it is not easily open to introspection. Indeed, if introspection were the sine qua non of rationality, then it would follow that the deployment of consequentialist intuitions is also arational. Although deontological intuitions are not infallible, the infirmities of deontological intuitions are equally shared by utilitarian intuitions. Thus, contrary to Greene’s recommendation, one need not abandon her deontological moral intuitions. Instead, intuitions – be they deontological or consequentialist – can be useful tools to guide moral reasoning. (shrink)

Over the past decade, there has been an explosion of scientific research into the nature of our moral psychology that demonstrates that human morality is fully grounded in the natural world and, thus, part of our evolved nature. Yet, many, if not most, scholars in the social sciences and humanities remain sceptical or pessimistic. Looking at a number of these recurrent concerns, I identify the source of this resistance as ‘moral creationism’: a set of beliefs, grounded in relativism and romanticism, (...) about morality as irreducibly complex, holistic and non-decomposable, and that, therefore, implicates the scientific approach to morality as irrelevant, misguided, or in the extreme, itself somehow taboo or unethical. I demonstrate that moral creationism is intellectually unfounded by examining evidence on moral diversity and universality, moral and conventional norms, emotion and reasoning in moral judgment, moral conflict, moral progress and religion and morality. I argue that rejecting moral creationism not only prevents an inaccurate view of our moral psychology, but also has implications for the plausibility and justification of various normative theories, for reforming the practice of moral philosophy and can inform applied ethical areas. Without the protective strategy of moral creationism as a default position, humanists as well as scientists will both benefit as already fruitful inquiry, constructive engagement, collaboration and incorporation of novel investigative methods across disciplines can continue to grow.

We report the results of two experiments that show that participants rely on both emotion and reason in moral judgments. Experiment 1 showed that when participants were primed to communicate feelings, they provided emotive justifications not only for personal dilemmas, e.g., pushing a man from a bridge that will result in his death but save the lives of five others, but also for impersonal dilemmas, e.g., hitting a switch on a runaway train that will result in the death of one (...) man but save the lives of five others; when they were primed to communicate thoughts, they provided non-emotive justifications for both personal and impersonal dilemmas. Experiment 2 showed that participants read about a protagonist's emotions more quickly when the protagonist was faced with a personal dilemma than an impersonal one, but they read about the protagonist's decision to act or not act equally quickly for personal and impersonal dilemmas.

While there is much evidence for the influence of automatic emotional responses on moral judgment, the roles of reflection and reasoning remain uncertain. In Experiment 1, we induced subjects to be more reflective by completing the Cognitive Reflection Test prior to responding to moral dilemmas. This manipulation increased utilitarian responding, as individuals who reflected more on the CRT made more utilitarian judgments. A follow-up study suggested that trait reflectiveness is also associated with increased utilitarian judgment. In Experiment 2, subjects considered (...) a scenario involving incest between consenting adult siblings, a scenario known for eliciting emotionally driven condemnation that resists reasoned persuasion. Here, we manipulated two factors related to moral reasoning: argument strength and deliberation time. These factors interacted in a manner consistent with moral reasoning: A strong argument defending the incestuous behavior was more persuasive than a weak argument, but only when increased deliberation time encouraged subjects to reflect.

We examined the effects of order of presentation on the moral judgments of professional philosophers and two comparison groups. All groups showed similar-sized order effects on their judgments about hypothetical moral scenarios targeting the doctrine of the double effect, the action-omission distinction, and the principle of moral luck. Philosophers' endorsements of related general moral principles were also substantially influenced by the order in which the hypothetical scenarios had previously been presented. Thus, philosophical expertise does not appear to enhance the stability (...) of moral judgments against this presumably unwanted source of bias, even given familiar types of cases and principles.

Influential theories on moral judgments propose that they rely either on emotions or on innate moral principles. In contrast, the mental model theory postulates that moral judgments rely on reasoning, either intuition or deliberation. The theory allows for the possibility that intuitions lead to utilitarian judgments. This paper reports two experiments involving fifth-grade children, adolescents, and adults; the results revealed that children reason intuitively to resolve moral dilemmas in which action and inaction lead to different outcomes. In particular, the results (...) showed female children to be more utilitarian than female adults in resolving classical moral dilemmas: they preferred an action that achieved a good outcome for a greater number of people. Within the mental model theory’s framework there is no reason to expect that females and males differ in their ability to reason, but at the moment the results for females cannot be generalized to males who were not properly represented in the adults groups of the two experiments. The result revealing that (female) children are more utilitarian than (female) adults, which is hard to explain via many current theories, was predicted by the mental model theory. (shrink)

Professions have a social obligation to ensure that their members’ professional behavior is morally appropriate. The psychology profession in most jurisdictions delegates the responsibility of ensuring that psychologists entering the profession are ethically competent to pre-practicum training programs. Educators responsible for teaching the ethics courses in these programs often base them on Rest’s (1984, 1994) theory that does not take into account a vast amount of contemporary psychological and neuroscientific research data on moral decision making. My aim with this article (...) is therefore to summarize the psychological and neuroscience research findings relevant to moral decision making and consider how educators who teach ethics courses can apply them in developing ethics courses grounded in research.

In this article I ask what recent moral psychology and neuroscience can and can’t claim to have discovered about morality. I argue that the object of study of much recent work is not morality but a particular kind of individual moral judgment. But this is a small and peculiar sample of morality. There are many things that are moral yet not moral judgments. There are also many things that are moral judgments yet not of that particular kind. If moral things (...) are various and diverse, then empirical research about one kind of individual moral judgment doesn’t warrant theoretical conclusions about morality in general. If that kind of individual moral judgment is a peculiar and rare thing, then it is not obvious what it tells us about other moral things. What is more, it is not obvious what its theoretical importance is to begin with—that is, why we should care about it at all. In light of these arguments, I call for a pluralism of methods and objects of inquiry in the scientific investigation of morality, so that it transcends its problematic overemphasis on a particular kind of individual moral judgment.

Gender greatly impacts access to opportunities, potential, and success in corporate leadership roles. We begin with a general presentation of why such discussion is necessary for basic considerations of justice and fairness in gender equality and how the issues we raise must impact any ethical perspective on gender in the corporate workplace. We continue with a breakdown of the central categories affecting the success of women in corporate leadership roles. The first of these includes gender-influenced behavioral factors, such as the (...) requirements and expectations of gendered verbal and nonverbal communication styles as well as appearance. We move on to address the impact of family on corporate leadership opportunities and success, discussing the asymmetrical evaluation of an individual’s potential, authority, and competence based on gender stereotypes of familial obligations and expectations. Finally, we address how gender impacts access to networking and sponsorship opportunities and the long-term effects of systematic limitations on women’s inclusion in the upper echelons of corporate leadership. We conclude with a summary of the questions and issues raised by our discussion and direct individuals to consider how different ethical systems and moral requirements might influence their interpretations of gender and leadership in the corporate workplace.

The present study aims to examine the relationship between the cortical midline structures (CMS), which have been regarded to be associated with selfhood, and moral decision making processes at the neural level. Traditional moral psychological studies have suggested the role of moral self as the moderator of moral cognition, so activity of moral self would present at the neural level. The present study examined the interaction between the CMS and other moral-related regions by conducting psycho-physiological interaction analysis of functional images (...) acquired while 16 subjects were solving moral dilemmas. Furthermore, we performed Granger causality analysis to demonstrate the direction of influences between activities in the regions in moral decision-making. We first demonstrate there are significant positive interactions between two central CMS seed regions—i.e., the medial prefrontal cortex (MPFC) and posterior cingulate cortex (PCC)—and brain regions associated with moral functioning including the cerebellum, brainstem, midbrain, dorsolateral prefrontal cortex, orbitofrontal cortex and anterior insula (AI); on the other hand, the posterior insula (PI) showed significant negative interaction with the seed regions. Second, several significant Granger causality was found from CMS to insula regions particularly under the moral-personal condition. Furthermore, significant dominant influence from the AI to PI was reported. Moral psychological implications of these findings are discussed. The present study demonstrated the significant interaction and influence between the CMS and morality-related regions while subject were solving moral dilemmas. Given that, activity in the CMS is significantly involved in human moral functioning. (shrink)
