Project description:While we may think about harm as primarily being about physical injury, harm can also take the form of negative psychological impact. Using functional magnetic resonance imaging, we examined the extent to which moral judgments of physical and psychological harms are processed similarly, focusing on brain regions implicated in mental state reasoning or theory of mind, a key cognitive process for moral judgment. First, univariate analyses reveal item-specific features that lead to greater recruitment of theory of mind regions for psychological harm versus physical harm. Second, multivariate pattern analyses reveal sensitivity to the psychological/physical distinction in two regions implicated in theory of mind: the right temporoparietal junction and the precuneus. Third, we find no reliable differences between neurotypical adults and adults with autism spectrum disorder with regard to neural activity related to theory of mind during moral evaluations of psychological and physical harm. Altogether, these results reveal neural sensitivity to the distinction between psychological harm and physical harm.

Project description:Previous studies have shown that observing another's pain can evoke other-oriented emotions, which instigate empathic concern for another's needs. It is not clear whether experiencing first-hand physical pain may also evoke other-oriented emotion and thus influence people's moral judgment. Based on the embodied simulation literature and neuroimaging evidence, the present research tested the idea that participants who experienced physical pain would be more sympathetic in their moral judgments. Study 1 showed that ice-induced physical pain facilitated higher self-assessments of empathy, which motivated participants to be more sympathetic in their moral judgments. Study 2 confirmed findings in study 1 and also showed that State Perspective Taking subscale of the State Empathy Scale mediated the effects of physical pain on moral judgment. These results provide support for embodied view of morality and for the view that pain can serve a positive psychosocial function.

Project description:Our research brings to light features of the social world that impact moral judgments and how they do so. The moral vignette data presented were collected in rural and urban Croatian communities that were involved to varying degrees in the Croatian Homeland War. We argue that rapid shifts in moral accommodations during periods of violent social strife can be explained by considering the role that coordination and social agents' ability to reconfigure their social network (i.e., relational mobility) play in moral reasoning. Social agents coordinate on (moral) norms, a general attitude which broadly facilitates cooperation, and makes possible the collective enforcement of compliance. During social strife interested parties recalibrate their determination of others' moral standing and recast their established moral circle, in accordance with their new or prevailing social investments. To that extent, social coordination-and its particular promoters, inhibitors, and determinants-effects significant changes in individuals' ranking of moral priorities. Results indicate that rural participants evaluate the harmful actions of third parties more harshly than urban participants. Coordination mediates that relationship between social environment and moral judgment. Coordination also matters more for the moral evaluation of the harmful actions of moral scenarios involving characters belonging to different social units than for scenarios involving characters belonging to the same group. Participants high in relational mobility-that ability to recompose one's social network-moralize similarly wrongdoings perpetrated by both in- and out-group members. Those low in relational mobility differentiate when an out-group member causes the harm. Additionally, perceptions of third-party guilt are also affected by specifics of the social environment. Overall, we find that social coordination and relational mobility affect moral reasoning more so than ethnic commitment.

Project description:This study presents the first neuroimaging investigation of female psychopathy in an incarcerated population. Prior studies have found that male psychopathy is associated with reduced limbic and paralimbic activation when processing emotional stimuli and making moral judgments. The goal of this study was to investigate whether these findings extend to female psychopathy. During fMRI scanning, 157 incarcerated and 46 non-incarcerated female participants viewed unpleasant pictures, half which depicted moral transgressions, and neutral pictures. Participants rated each picture on moral transgression severity. Psychopathy was assessed using the Psychopathy Checklist-Revised (PCL-R) in all incarcerated participants. Non-incarcerated participants were included as a control group to derive brain regions of interest associated with viewing unpleasant vs. neutral pictures (emotion contrast), and unpleasant pictures depicting moral transgressions vs. unpleasant pictures without moral transgressions (moral contrast). Regression analyses in the incarcerated group examined the association between PCL-R scores and brain activation in the emotion and moral contrasts. Results of the emotion contrast revealed a negative correlation between PCL-R scores and activation in the right amygdala and rostral anterior cingulate. Results of the moral contrast revealed a negative correlation between PCL-R scores and activation in the right temporo-parietal junction. These results indicate that female psychopathy, like male psychopathy, is characterized by reduced limbic activation during emotion processing. In contrast, reduced temporo-parietal activation to moral transgressions has been less observed in male psychopathy. These results extend prior findings in male psychopathy to female psychopathy, and reveal aberrant neural responses to morally-salient stimuli that may be unique to female psychopathy.

Project description:Whether cleanliness influences moral judgments has recently become a topic of debate in the psychological literature. After the initial report that activating the notion of physical purity can result in less severe moral judgments (Schnall et al., 2008a), a direct replication (Johnson et al., 2014a) with much larger sample sizes failed to yield similar findings. The current paper examines the possibility that only non-conscious activation of the cleanliness concept, as achieved in participants with low response effort on priming materials, can produce the expected effect. An online replication (Study 1, N = 214) provided evidence that, when participants exerted low (yet still acceptable) levels of response effort to the experimental material, cleanliness priming led to more lenient moral judgments than neutral priming. An online experiment (Study 2, N = 440; replicated in Study 2a, N = 436) manipulating participants' effort on the priming task (low vs. high) supported the hypothesized mechanism. Specifically, respondents in the low response effort group were instructed to complete the priming task as quickly as possible without too much attention, and the cleanliness priming resulted in less extreme moral judgments than the neutral condition as expected. In contrast, respondents in the high response effort group were instructed to perform to the best of their ability on the priming task, with a non-significant difference on moral ratings between cleanliness and neutral conditions. In addition to helping resolve the controversy regarding the cleanliness hypothesis, the current paper calls into attention the role of response effort in the execution and replication of priming studies.

Project description:The amygdala is a subcortical structure implicated in both the expression of conditioned fear and social fear recognition. Social fear recognition deficits following amygdala lesions are often interpreted as reflecting perceptual deficits, or the amygdala's role in coordinating responses to threats. But these explanations fail to capture why amygdala lesions impair both physiological and behavioural responses to multimodal fear cues and the ability to identify them. We hypothesized that social fear recognition deficits following amygdala damage reflect impaired conceptual understanding of fear. Supporting this prediction, we found specific impairments in the ability to predict others' fear (but not other emotions) from written scenarios following bilateral amygdala lesions. This finding is consistent with the suggestion that social fear recognition, much like social recognition of states like pain, relies on shared internal representations. Preserved judgements about the permissibility of causing others fear confirms suggestions that social emotion recognition and morality are dissociable.

Project description:Judgments of whether an action is morally wrong depend on who is involved and the nature of their relationship. But how, when, and why social relationships shape moral judgments is not well understood. We provide evidence to address these questions, measuring cooperative expectations and moral wrongness judgments in the context of common social relationships such as romantic partners, housemates, and siblings. In a pre-registered study of 423 U.S. participants nationally representative for age, race, and gender, we show that people normatively expect different relationships to serve cooperative functions of care, hierarchy, reciprocity, and mating to varying degrees. In a second pre-registered study of 1,320 U.S. participants, these relationship-specific cooperative expectations (i.e., relational norms) enable highly precise out-of-sample predictions about the perceived moral wrongness of actions in the context of particular relationships. In this work, we show that this 'relational norms' model better predicts patterns of moral wrongness judgments across relationships than alternative models based on genetic relatedness, social closeness, or interdependence, demonstrating how the perceived morality of actions depends not only on the actions themselves, but also on the relational context in which those actions occur.

Project description:Intentional harms are typically judged to be morally worse than accidental harms. Distinguishing between intentional harms and accidents depends on the capacity for mental state reasoning (i.e., reasoning about beliefs and intentions), which is supported by a group of brain regions including the right temporo-parietal junction (RTPJ). Prior research has found that interfering with activity in RTPJ can impair mental state reasoning for moral judgment and that high-functioning individuals with autism spectrum disorders make moral judgments based less on intent information than neurotypical participants. Three experiments, using multivoxel pattern analysis, find that (i) in neurotypical adults, the RTPJ shows reliable and distinct spatial patterns of responses across voxels for intentional vs. accidental harms, and (ii) individual differences in this neural pattern predict differences in participants' moral judgments. These effects are specific to RTPJ. By contrast, (iii) this distinction was absent in adults with autism spectrum disorders. We conclude that multivoxel pattern analysis can detect features of mental state representations (e.g., intent), and that the corresponding neural patterns are behaviorally and clinically relevant.

Project description:Previous research emphasizes people's dispositions as a source of differences in moral views. We investigate another source of moral disagreement, self-interest. In three experiments, participants played a simple economic game in which one player divides money with a partner according to the principle of equality (same payoffs) or the principle of equity (pay-offs proportional to effort expended). We find, first, that people's moral judgment of an allocation rule depends on their role in the game. People not only prefer the rule that most benefits them but also judge it to be more fair and moral. Second, we find that participants' views about equality and equity change in a matter of minutes as they learn where their interests lie. Finally, we find limits to self-interest: when the justification for equity is removed, participants no longer show strategic advocacy of the unequal division. We discuss implications for understanding moral debate and disagreement.

Project description:IntroductionAlthough there is convincing evidence for socio-cognitive impairments in schizophrenia spectrum disorder (SSD), little evidence is found for deficient moral cognition. We investigated whether patients with SSD showed altered moral judgments in a story task where the protagonist either had a neutral or malicious intention towards another person. This paradigm examined whether SSD relates to altered moral cognition in general or specifically to impaired integration of prior information (such as beliefs) in moral judgments.Methods23 patients and 32 healthy controls read vignettes created in a 2 x 2 design. The protagonist in each story either had a neutral or negative intention towards another person which, as a result, either died (negative outcome) or did not die (neutral outcome). Participants rated the moral permissibility of the protagonist's action. Standard null hypothesis significance testing and equivalent Bayes analyses are reported.ResultsSchizophrenia patients did not differ significantly in permissibility ratings from healthy controls. This finding was supported by the Bayes analyses which favoured the null hypothesis. Task performance was not related to symptom severity or medication.ConclusionsThe current findings do not support the notion that moral judgments are deficient in schizophrenia. Furthermore, the current study shows that patients do not have observable difficulties in integrating the protagonist's belief in the rating of the moral permissibility of the action-outcome.
