Choosing between the Emotional Dog and the Rational Pal: A Moral Dilemma with a Tail

ABSTRACT

Neuroscientific studies indicate moral cognition involves a cognitive struggle between two systems in the brain: the emotional “hot” system and the rational “cold” system. Past research has shown that when presented with personal dilemmas, individuals showed greater brain activity in the hot system areas. However, when further probed about their decisions, moral dumbfounding often occurs. Family selection may help explain moral judgments. Oftentimes, people consider their pets as part of their family. Based on the past research on moral decision-making, the current study presented a novel approach to exploring moral decision-making by forcing participants to choose to save the life between biological family and psychological-kin. Participants (n = 573) were given moral dilemmas and forced to decide whether to save humans or pets from imminent death. The level of relationship between the human shifted six times (foreign tourist, hometown stranger, distant cousin, best friend, grandparent, and sibling), while relationship to the pet had two levels (your pet, someone else's pet). Willingness to save a pet over a human consistently decreased as level of relationship between the participant and the human in the scenario increased. Participants were also more likely to save their own pet over a human life than someone else's pet over a human life. The results suggest that pets are often viewed as psychological-kin. Females were found to be more likely to save their pets over non-immediate family members than males (all ps < 0.05), suggesting that males and females may differ in the structure of their moral reasoning.     

My baby doesn't smell as bad as yours: The plasticity of disgust

Disgust is a powerful behavioral adaptation, which confers the advantage of reducing the risk of pathogen infection. However, there are situations in which disgust at core elicitors (e.g., feces) must be modulated in the service of other goals (e.g., caring for a close kin). In Study 1, mothers of infants completed a self-report questionnaire about their reactions to changing their baby's feces-soiled diaper compared with the diaper of someone else's baby. In Study 2, mothers of infants were presented with a series of trials in which they smelled concealed samples of their own baby's feces-soiled diaper and those of someone else's baby. In addition, labels were used to identify the source of the sample (correctly labeled, mislabeled, or no label). Both studies provide evidence suggesting that mothers regard their own baby's fecal smell as less disgusting than that from someone else's baby. Furthermore, labeling had relatively little influence on this effect, and the effect persisted when social desirability was controlled.     

Brain Regions Associated to a Kinesthetic Illusion Evoked by Watching a Video of One's Own Moving Hand

It is well known that kinesthetic illusions can be induced by stimulation of several sensory systems (proprioception, touch, vision…). In this study we investigated the cerebral network underlying a kinesthetic illusion induced by visual stimulation by using functional magnetic resonance imaging (fMRI) in humans. Participants were instructed to keep their hand still while watching the video of their own moving hand (Self Hand) or that of someone else''s moving hand (Other Hand). In the Self Hand condition they experienced an illusory sensation that their hand was moving whereas the Other Hand condition did not induce any kinesthetic illusion. The contrast between the Self Hand and Other Hand conditions showed significant activation in the left dorsal and ventral premotor cortices, in the left Superior and Inferior Parietal lobules, at the right Occipito-Temporal junction as well as in bilateral Insula and Putamen. Most strikingly, there was no activation in the primary motor and somatosensory cortices, whilst previous studies have reported significant activation in these regions for vibration-induced kinesthetic illusions. To our knowledge, this is the first study that indicates that humans can experience kinesthetic perception without activation in the primary motor and somatosensory areas. We conclude that under some conditions watching a video of one''s own moving hand could lead to activation of a network that is usually involved in processing copies of efference, thus leading to the illusory perception that the real hand is indeed moving.     

Modulation of Self-Esteem in Self- and Other-Evaluations Primed by Subliminal and Supraliminal Faces

Background

Past research examining implicit self-evaluation often manipulated self-processing as task-irrelevant but presented self-related stimuli supraliminally. Even when tested with more indirect methods, such as the masked priming paradigm, participants'' responses may still be subject to conscious interference. Our study primed participants with either their own or someone else''s face, and adopted a new paradigm to actualize strict face-suppression to examine participants'' subliminal self-evaluation. In addition, we investigated how self-esteem modulates one''s implicit self-evaluation and validated the role of awareness in creating the discrepancy on past findings between measures of implicit self-evaluation and explicit self-esteem.

Methodology/Principal Findings

Participants'' own face or others'' faces were subliminally presented with a Continuous Flash Suppression (CFS) paradigm in Experiment 1, but supraliminally presented in Experiment 2, followed by a valence judgment task of personality adjectives. Participants also completed the Rosenberg Self-Esteem Scale in each experiment. Results from Experiment 1 showed a typical bias of self-positivity among participants with higher self-esteem, but only a marginal self-positivity bias and a significant other-positivity bias among those with lower self-esteem. However, self-esteem had no modulating effect in Experiment 2: All participants showed the self-positivity bias.

Conclusions/Significance

Our results provide direct evidence that self-evaluation manifests in different ways as a function of awareness between individuals with different self-views: People high and low in self-esteem may demonstrate different automatic reactions in the subliminal evaluations of the self and others; but the involvement of consciousness with supraliminally presented stimuli may reduce this dissociation.     

African communal basis for autonomy and life choices

I argue that the metaphysical capacity of autonomy is not intrinsically valuable; it is valuable only when used in relation to a community's values and instrumentally for making the proper choices that will promote one's own and the community's well‐being. I use the example of the choice to take one's life by suicide to illuminate this view. I articulate a plausible African conception of personhood as a basis for the idea of relational autonomy. I argue that this conception is better understood as a social‐moral thesis, and not a metaphysical thesis. A metaphysical thesis gives an account of the abstract nature of an atomic individual, his agency, and rational choice. The social‐moral thesis indicates that personhood and autonomy are positive and relational to the life plans, well‐being, material conditions, and the best means for achieving them that are made available and possible by harmonious living in a community. This idea of autonomy is not just having the capacity of freewill; it also involves how such freewill is used, in terms of how an individual's choices are guided by internalized communal values.     

Public Intellectuals and Biotech Stocks

The stock market is a platform for the transfer of capital from all varieties of clever and avaricious creatures...mega-institutions, fools, ciphers and layabouts lucky enough to be heirs to fortunes...to those who need it to enable productive work.

Stock markets have been so exhaustively analyzed that it is inconceivable that you will find anything new here. Yet I'll take a stab at it: I am interested to know if bioscientists, whose opinions of technologies that drive biotech companies are informed by deep knowledge and analytical capabilities, might have an edge in stock picking. To find out about this, I propose an experiment.

Landes Bioscience will fund a biotech investment account. Investment decisions will be made solely by me with the advise of the stock market equivalent of the bioscience College of Cardinals [bCoC]: simply the first 20 bioscientists who sign on. Here are the terms of the experiment.

* The fund will start out with $20,000.

* The duration of the fund will be five years.

* When the fund ceases operation, whatever assets are in it will be disbursed equally to the bCoC.

* Stock decisions of the fund will be published regularly in Cell Cycle.

* The identity of the bCoC will not be disclosed.

Few things in life are quite as gratifying as living well, especially if it is managed off the ideas and effort of others. Clearly, this is what investing capital is all about, and it is a particularly attractive pursuit when investing someone else's money.

I like the idea of public intellectuals at the interface between science and commerce. This is the call for 20 bioscientists throughout the world to join me in that space.

Being Moved by the Self and Others: Influence of Empathy on Self-Motion Perception

Background

The observation of conspecifics influences our bodily perceptions and actions: Contagious yawning, contagious itching, or empathy for pain, are all examples of mechanisms based on resonance between our own body and others. While there is evidence for the involvement of the mirror neuron system in the processing of motor, auditory and tactile information, it has not yet been associated with the perception of self-motion.

Methodology/Principal Findings

We investigated whether viewing our own body, the body of another, and an object in motion influences self-motion perception. We found a visual-vestibular congruency effect for self-motion perception when observing self and object motion, and a reduction in this effect when observing someone else''s body motion. The congruency effect was correlated with empathy scores, revealing the importance of empathy in mirroring mechanisms.

Conclusions/Significance

The data show that vestibular perception is modulated by agent-specific mirroring mechanisms. The observation of conspecifics in motion is an essential component of social life, and self-motion perception is crucial for the distinction between the self and the other. Finally, our results hint at the presence of a “vestibular mirror neuron system”.     

The Effect of Self-Efficacy on Visual Discrimination Sensitivity

Can subjective belief about one''s own perceptual competence change one''s perception? To address this question, we investigated the influence of self-efficacy on sensory discrimination in two low-level visual tasks: contrast and orientation discrimination. We utilised a pre-post manipulation approach whereby two experimental groups (high and low self-efficacy) and a control group made objective perceptual judgments on the contrast or the orientation of the visual stimuli. High and low self-efficacy were induced by the provision of fake social-comparative performance feedback and fictional research findings. Subsequently, the post-manipulation phase was performed to assess changes in visual discrimination thresholds as a function of the self-efficacy manipulations. The results showed that the high self-efficacy group demonstrated greater improvement in visual discrimination sensitivity compared to both the low self-efficacy and control groups. These findings suggest that subjective beliefs about one''s own perceptual competence can affect low-level visual processing.     

Audience effects on moralistic punishment

Punishment has been proposed as being central to two distinctively human phenomena: cooperation in groups and morality. Here we investigate moralistic punishment, a behavior designed to inflict costs on another individual in response to a perceived moral violation. There is currently no consensus on which evolutionary model best accounts for this phenomenon in humans. Models that turn on individuals' cultivating reputations as moralistic punishers clearly predict that psychological systems should be designed to increase punishment in response to information that one's decisions to punish will be known by others. We report two experiments in which we induce participants to commit moral violations and then present third parties with the opportunity to pay to punish wrongdoers. Varying conditions of anonymity, we find that the presence of an audience—even if only the experimenter—causes an increase in moralistic punishment.     

Embodied economics: how bodily information shapes the social coordination dynamics of decision-making

To date, experiments in economics are restricted to situations in which individuals are not influenced by the physical presence of other people. In such contexts, interactions remain at an abstract level, agents guessing what another person is thinking or is about to decide based on money exchange. Physical presence and bodily signals are therefore left out of the picture. However, in real life, social interactions (involving economic decisions or not) are not solely determined by a person''s inference about someone else''s state-of-mind. In this essay, we argue for embodied economics: an approach to neuroeconomics that takes into account how information provided by the entire body and its coordination dynamics influences the way we make economic decisions. Considering the role of embodiment in economics—movements, posture, sensitivity to mimicry and every kind of information the body conveys—makes sense. This is what we claim in this essay which, to some extent, constitutes a plea to consider bodily interactions between agents in social (neuro)economics.     

Understanding Others' Regret: A fMRI Study

Previous studies showed that the understanding of others'' basic emotional experiences is based on a “resonant” mechanism, i.e., on the reactivation, in the observer''s brain, of the cerebral areas associated with those experiences. The present study aimed to investigate whether the same neural mechanism is activated both when experiencing and attending complex, cognitively-generated, emotions. A gambling task and functional-Magnetic-Resonance-Imaging (fMRI) were used to test this hypothesis using regret, the negative cognitively-based emotion resulting from an unfavorable counterfactual comparison between the outcomes of chosen and discarded options. Do the same brain structures that mediate the experience of regret become active in the observation of situations eliciting regret in another individual? Here we show that observing the regretful outcomes of someone else''s choices activates the same regions that are activated during a first-person experience of regret, i.e. the ventromedial prefrontal cortex, anterior cingulate cortex and hippocampus. These results extend the possible role of a mirror-like mechanism beyond basic emotions.     

How is Scientific Credibility Affected by Communicating Uncertainty? The Case of Endocrine Disrupter Effects on Male Fertility

Using the case of endocrine disrupter effects on male fertility, we explored how communicating uncertainty influences the credibility of the information that laypeople receive from scientists and how laypeople form judgments about the relationship between uncertainty and credibility. We found that laypeople assess the credibility of scientific information—whether or not it is accompanied by uncertainty—by referencing their “science model” and using non-scientific references (i.e., situations encountered in one's daily life, information received from other sources, one's own observations of the world, and one's education or professional experience). Scientific credibility is a mixture of (sometimes contradictory) considerations along these different axes. Previous studies have found that some scientists assume that communicating uncertainty will lower public credibility of science. Our results contradict this assumption for situations in which academic scientists communicate uncertainty, which is perceived as additional knowledge bringing a new perspective on certain information. People expect scientists to provide practical solutions and feel disillusionment when scientists lack straight answers. However, they accepted uncertainty as an intrinsic characteristic of science and a consequence of the limits to human beings’ capacity to understand the world. Further, the low credibility of industry scientists is further reinforced when they communicate uncertainty.     

Corticospinal Excitability Modulation During Action Observation

This study used the transcranial magnetic stimulation/motor evoked potential (TMS/MEP) technique to pinpoint when the automatic tendency to mirror someone else''s action becomes anticipatory simulation of a complementary act. TMS was delivered to the left primary motor cortex corresponding to the hand to induce the highest level of MEP activity from the abductor digiti minimi (ADM; the muscle serving little finger abduction) as well as the first dorsal interosseus (FDI; the muscle serving index finger flexion/extension) muscles. A neuronavigation system was used to maintain the position of the TMS coil, and electromyographic (EMG) activity was recorded from the right ADM and FDI muscles. Producing original data with regard to motor resonance, the combined TMS/MEP technique has taken research on the perception-action coupling mechanism a step further. Specifically, it has answered the questions of how and when observing another person''s actions produces motor facilitation in an onlooker''s corresponding muscles and in what way corticospinal excitability is modulated in social contexts.     

Early prosociality is conditional on opportunity cost and familiarity with the target

Developmental research in the past decade has painted the picture of a gregarious child ready to engage in a range of prosocial behavior, but less is known about the situational factors that moderate this behavior. The present study investigated the effects of cost and familiarity on children's readiness to help the victim of a moral transgression. Opportunity cost was operationalized as the time and effort expended on providing help, that could otherwise be used to earn a reward from a productive task. Familiarity varied as a function of whether there was prior contact between the child and victim. Five- and six-year-olds in Singapore (N = 120) witnessed an adult transgressor destroy the victim's tower of blocks, responded to the victim's pleas for help in rebuilding her tower, and shared resources with both actresses. Contrary to our initial predictions, children helped a familiar victim less when cost was high as opposed to low, but helped an unfamiliar victim equally regardless of cost. Additionally, helping rates were low (30–60%) except in the least prohibitive condition (> 80%; Low-Cost, Familiar Victim), stemming from a combination of not having a productive task to occupy one's time and energy, and simultaneously a familiar target which increased one's intrinsic motivation to help. The conditional limits imposed on children's decision to help thus appear to be, “I'll help, if I know you and have nothing better to do!” In terms of resource sharing, children behaved selfishly toward both the victim and transgressor regardless of their familiarity with the victim. Altogether, our findings suggest that children consider self-interest when deciding whether to help and share with others.     

Induction versus modulation in phytochrome-regulated biochemical processes

The time course of appearance of competence towards phytochrome (P_fr) was studied in cotyledons of mustard (Sinapis alba L.) with regard to the light-mediated formation of anthocyanin (aglycone cyanidin) and NADP-dependent plastidal glyceraldehyde-3-phosphate dehydrogenase (GPD, EC 1.2.1.13). The experiments were performed to answer the following question: Does phytochrome act to turn responses on (induction), or — as an alternative — does phytochrome cause an amplification of processes already occurring in absolute darkness albeit at low rates once competence is reached (modulation)? The data show that in the case of GPD, phytochrome causes an amplification of the rate of synthesis once the competence point is reached at approximately 36 h after sowing at 25° C. In the case of anthocyanin, it was found that two distinct points of competence exist (26 h and 39 h after sowing, 25° C). In the case of ‘early anthocyanin’ (competence point at 26 h), synthesis does not occur in darkness without P_fr, while in the case of ‘late anthocyanin’ (competence point at 39 h), phytochrome causes an amplification of a process occurring in complete darkness albeit at a very low rate. It is concluded that in phytochrome-mediated photomorphogenesis, modulation as well as induction of biosynthetic processes plays a role.     

Autonomy is a Right,Not a Feat: How Theoretical Misconceptions have Muddled the Debate on Dynamic Consent to Biobank Research

Should people be involved as active participants in longitudinal medical research, as opposed to remaining passive providers of data and material? We argue in this article that misconceptions of ‘autonomy’ as a kind of feat rather than a right are to blame for much of the confusion surrounding the debate of dynamic versus broad consent. Keeping in mind two foundational facts of human life, freedom and dignity, we elaborate three moral principles – those of autonomy, integrity and authority – to better see what is at stake. Respect for autonomy is to recognize the other's right to decide in matters that are important to them. Respect for integrity is to meet, in one's relationship with the other, their need to navigate the intersection between private and social life. Respect for authority is to empower the other – to help them to cultivate their responsibility as citizens. On our account, to force information onto someone who does not want it is not to respect that person's autonomy, but to violate integrity in the name of empowerment. Empowerment, not respect for autonomy, is the aim that sets patient‐centred initiatives employing a dynamic consent model apart from other consent models. Whether this is ultimately morally justified depends on whether empowerment ought to be a goal of medical research, which is questionable.     

Social observation increases deontological judgments in moral dilemmas

A concern for positive reputation is one of the core motivations underlying various social behaviors in humans. The present study investigated how experimentally induced reputation concern modulates judgments in moral dilemmas. In a mixed-design experiment, participants were randomly assigned to the observed vs. the control group and responded to a series of trolley-type moral dilemmas either in the presence or absence of observers, respectively. While no significant baseline difference in personality traits and moral decision tendency were found across two groups of participants, our analyses revealed that social observation promoted deontological judgments especially for moral dilemmas involving direct bodily harm (i.e., personal moral dilemmas), yet with an overall decrease in decision confidence and significant prolongation of reaction time. Moreover, participants in the observed group, but not in the control group, showed the increased sensitivities towards warmth vs. competence traits words in the lexical decision task performed after the moral dilemma task. Our findings suggest that reputation concern, once triggered by the presence of potentially judgmental others, could activate a culturally dominant norm of warmth in various social contexts. This could, in turn, induce a series of goal-directed processes for self-presentation of warmth, leading to increased deontological judgments in moral dilemmas. The results of the present study provide insights into the reputational consequences of moral decisions that merit further exploration.     

Physician self-awareness: the neglected insight.

Self-awareness is vital to a physician''s development. Understanding the impact of our internal subjective world on our attitudes and values and on the fantasies we have of reality is important to us as doctors. Some of the means of acquiring this self-knowledge include accurately perceiving the reflection of one''s self in patients, understanding one''s learning style, studying and enjoying the humanities, expressing one''s self creatively, maintaining a sense of humour and examining one''s reaction to experiences. When confronted by a person who is ill the physician must take action that is constructive and affirmative and not compromised by behaviour that originates in unexamined personal issues.     

Engagement as co‐constructing knowledge: A moral necessity in public health research

Undertaking engagement in public health research is ethically essential. There is a growing emphasis on practicing engagement as the co‐construction of knowledge, which goes beyond other common forms of engagement in health research practice: consulting and informing. Taking such an approach means researchers jointly construct knowledge with research users and beneficiaries; all parties design and conduct research together and share decision‐making power. This article makes the normative argument that such engagement is necessary to achieve the foundational moral aims of public health research—building relations of equality and addressing the health needs of those considered disadvantaged—which reflect the field's underlying commitment to social justice. It next identifies and discusses three ways in which co‐constructing knowledge advances those moral aims: by facilitating self‐determination, supporting individuals’ right to research, and maximizing social knowledge to address cognitive and epistemic injustice. Objections to the arguments presented in the article are then articulated and defended against.
