Abstract	There is growing research into contributing processes and biological correlates of moral inclinations. Recently, a negative association between utilitarianism and resting heart rate variability (HRV) as an indicator of cardiac vagal tone/parasympathetic activity was reported. We aimed to replicate and extend these findings by additionally investigating the sympathetic parameter electro-dermal activity (EDA), but found no associations in the total sample (N = 157). However, when taking sex and the use of combined oral contraceptives (COC) into account, we found a positive association between HRV and estimated deontology in women using COC and men, while in free cycling women there was a negative association. While no direct replication, our results also point to associations between higher HRV and decreased endorsement of harmful actions that serve a greater good. Unlike HRV, EDA showed no associations with moral judgements. In addition, there were correlations between personality traits and moral judgement.

Abstract	Safeguarding the rights of minorities is crucial for just societies. However, there are conceivable situations where minority rights might seriously impede the rights of the majority. Favoring the minority in such cases constitutes a violation of utilitarian principles. To explore the emotional, cognitive, and punitive responses of observers of such utilitarian rule transgressions, we conducted an online study with 1004 participants. Two moral scenarios (vaccine policy and epidemic) were rephrased in the third-party perspective. In both public health-related scenarios, the protagonist opted against the utilitarian option, which resulted in more fatalities in total, but avoided harm to a minority. Importantly, in vaccine policy, members of the minority cannot be identified beforehand and thus harm to them would have been rather accidental. Contrariwise, in epidemic, minority members are identifiable and would have needed to be deliberately selected. While the majority of participants chose not to punish the scenarios' protagonists at all, 30.1% judged that protecting the minority over the interests of the majority when only accidental harm would have occurred (vaccine policy) was worthy of punishment. In comparison, only 11.2% opted to punish a protagonist whose decision avoided deliberately selecting (and thus harming) a minority at the cost of the majority (epidemic). Emotional responses and appropriateness ratings paralleled these results. Furthermore, complex personality × situation interactions revealed the influence of personality features, i.e., trait psychopathy, empathy, altruism, authoritarianism, need for cognition and faith in intuition, on participants' responses. The results further underscore the need to consider the interaction of situational features and inter-individual differences in moral decisions and sense of justice.

Abstract	Differences in moral sentiments are widespread. Increasingly, their biological correlates are investigated to elucidate potential sources of divergent moral attitudes and choices. Serotonin is one such potential modulator. We investigated the effects of a functional serotonergic polymorphism, 5-HTTLPR, which was previously linked to moral choices albeit with inconsistent findings. N = 157 healthy young adults completed a set of congruent and incongruent moral dilemmas. In addition to the traditional moral response score, this set allows by using a process dissociation (PD) approach an estimation a deontological and a utilitarian parameter. While there was no main effect of 5-HTTLPR on any of the three moral judgement parameters, there was an interaction effect between 5-HTTLPR and endocrine status on PD parameters, which was mainly due to the deontological but not the utilitarian parameter. In men and free cycling women, LL homozygotes showed reduced deontological tendencies compared to S allele carriers. Contrariwise, in women using oral contraceptives, LL homozygotes had increased deontology parameter scores. Furthermore, LL genotypes in general reported less difficulty in making harmful choices, which were in addition associated with less negative emotions. The findings suggest that 5-HTTLPR might be involved in modulating cognitive and emotional processes contributing to moral decisions.

Abstract	Aside from cultural, psychological, or situational factors, differences in moral judgements might also be influenced by biological variables. Since previous studies have reported stronger utilitarian tendencies in men, the relationship between testosterone and moral judgments has gained interest. Utilitarian judgements focus on the consequences of an action in terms of a cost-benefit analysis while deontological judgements are based on rules that are independent of an action's outcome or of situational features. We investigated decisions in moral dilemma situations in N = 157 young adults using a process dissociation approach to allow an independent estimate of underlying utilitarianism and deontology. Significant effects of sex (p = .009) and endocrine status (p = .011) on utilitarianism were found with the highest levels in men and the lowest in free cycling women while oral contraceptive users fell in between. Furthermore, there were correlations of salivary testosterone with utilitarianism in free cycling women (r = .303) and with deontology in men (r = -0.263) while no significant associations between testosterone and moral choices were found in oral contraceptive users. However, the duration of contraceptive use correlated negatively with deontology (r = -.316). The findings underscore the role of sex, endocrine status as well as testosterone in moral judgements but also point to specific associations depending on sex and oral contraceptive use.

Abstract	Killing people is universally considered reprehensible and evokes in observers a need to punish perpetrators. Here, we explored how observers' personality is associated with their cognitive, emotional, and punishing reactions towards perpetrators using data from 1,004 participants who responded to a set of fifteen third-party perspective moral dilemmas. Among those, four scenarios (architect, life boat, footbridge, smother for dollars) describing deliberate killings were compared to investigate the role of the content features "motive for killing" (selfish vs. utilitarian) and "evitability of victims' death". Participants' moral appropriateness ratings, emotions towards perpetrators, and assigned punishments revealed complex scenario-personality interactions. Trait psychopathy was associated with harsher punishments in all scenarios but also with less concern about killing in general, an increased moral appreciation of utilitarian motives for killing, and a reduced concern about the killing of avoidable victims. Need for cognition was associated with considering a utilitarian motive for killing as a mitigating factor, while intuitive/authority-obedient thinking was linked to a strong focus on avoidability of harm as an aggravating factor when assigning punishments. Other-oriented empathy, trait anxiety, and justice sensitivity did not account for differences in third-party punishments. Our explorative findings highlight the importance of inter-individual differences for moral decision making and sense of justice.

Abstract	Emotional reactivity varies across the menstrual cycle although physiological findings are not entirely consistent. We assessed facial EMG and heart rate (HR) changes in healthy free cycling women (N = 45) with an emotional startle paradigm both during the early follicular and the late luteal phase, verified by repeated salivary 17β-estradiol, progesterone and testosterone assessments. Cycle phase impacted startle responses with larger magnitudes during the luteal phase. Notably, this effect was only present when premenstrual symptoms and sequence of lab sessions were included as co-variates. At rest, participants showed a tendency towards higher HR and reduced high frequency (HF) power during the luteal phase indicating reduced parasympathetic tone. HF power was also negatively associated with startle magnitudes. HR changes in response to emotional images differed between the two cycle phases. Initial HR deceleration was more marked during the follicular phase particularly when viewing negative pictures. However, cycle phase did not significantly impact corrugator and zygomaticus activity in response to emotional pictures. Among the three gonadal steroids, correlation patterns were most consistent for testosterone. During the follicular phase, testosterone was associated with zygomaticus activity while viewing neutral or positive pictures and with less pronounced HR deceleration in response to negative images. During the luteal phase, testosterone was negatively associated with fear potentiated startle. The findings underscore the importance of considering menstrual cycle phase when investigating physiological indicators of emotion. However, the modulating effect of premenstrual symptoms also emphasizes potential inter-individual differences.
