The models of internal self-control that have recently been proposed by behavioral economists do not depict motivational interaction that occurs while temptation is present. Those models that include willpower at all either envision a faculty with a motivation (“strength”) different from the motives that are weighed in the marketplace of choice, or rely on incompatible goals among diverse brain centers. Both assumptions are questionable, but these models’ biggest problem is that they do not let resolutions withstand re-examination while being challenged (...) by impulsive alternatives. The economists’ models all attempt to make a single equilibrium preference predictable from a person’s prior incentives. This was the original purpose of these models’ hyperboloid (“β–δ”) delay discount functions, which have been widely justified by the assumption that a person’s intertemporal inconsistency (impulsiveness) can be accounted for by the arousal of appetite for visceral rewards. Although arousal is clearly a factor in some cases of intertemporal inconsistency, it cannot be blamed for others, and furthermore does not necessarily imply hyperboloid discounting. The inadequacy of β–δ functions is particularly evident in models of internal self-control. I have reviewed several of these models, and have argued for a return to pure hyperbolic discount function as originally proposed, the relatively high tails of which can motivate a recursive process of self-prediction and thereby the formation of self-enforcing intertemporal contracts. Such a process does not require a separately motivated faculty of will, or incompatible goals among brain centers; but it also does not permit the prediction of unique preferences from prior incentives.

Risky behaviour may be associated with visceral experiences, such as increased heart rate. Previous studies examining the relationship between perception of such signals (interoception) and risk-taking typically used behavioural tasks with potential for monetary reward. This approach may be less informative for understanding general risk propensity. In addition, such research does not usually consider the varied ways individuals engage with interoceptive signals. However, examining these different forms of engagement may help us understand how subjective experience of interoception influences (...) risk-taking. As such, we performed two surveys (n = 471, primarily young adults) to examine the relationship between self-reported engagement with interoceptive signals (measured using the Multidimensional Assessment of Interoceptive Awareness) and a generalised measure of risk propensity (the General Risk Propensity Scale). Results indicated that different ways of interpreting or engaging with interoceptive signals were differentially associated with risk propensity. In particular, they provide preliminary evidence that those with the ability to ignore or not worry about visceral signals when they are uncomfortable display greater risk propensity (and these effects may possibly be gender-specific).

Abstract: Each affective state has distinct motor-expressions, sensory perceptions, autonomic, and cognitive patterns. Panksepp (1998) proposed seven neural affective systems of which the SEEKING system, a generalized approach-seeking system, motivates organisms to pursue resources needed for survival. When an organism is presented with a novel stimulus, the dopamine (DA) in the nucleus accumbens septi (NAS) is released. The DA circuit outlines the generalized mesolimbic dopamine-centered SEEKING system and is especially responsive when there is an element of unpredictability in forthcoming rewards. (...) We propose that when the outcome of this interaction is unexpected or unanticipated then Panksepp’s “cognitive or expectancy reset” mechanism involving the cognitive dissonance would yield the subjective emotion of surprise. In order to appropriately react to the environment’s stimuli one needs fundamental processes that would enable one to distinguish between what is novel and what has been already experienced, as well as the different degrees of novelty. Novel events are those whose essential features of the representation (visceral and perceptual) are altered and being discrepant provoke more sustained attention. Novelty arises from salient and arousing events and the organism experiences surprise, as coming out of a habitual state. In this framework, we shall look at established theories of emotions and propose a different approach to their taxonomy. (shrink)

It has been known for over a century that there is an afferent, as well as an efferent, component to the visceral-atonomic nervous system. Despite the fundamental importance of bodily afferent information- sometimes called interoception- to central nervous system control of visceral organ function, emotional-motivational processes, and dysfunction of these processes, including psychosomatic disorders, its role did not receive much attention until quite recently. This is the first comprehensive review of this topic and it covers both neurobiological and (...) psychobiological aspects. The author first defines the issue and gives an historical background starting with the James-Lange theory of emotion, and addresses learning and motivation, roots in Pavlovian conditioning research, and operant conditioning of visceral function. In the second section he reviews recent scientific findings in the neural basis of visceral perception and studies in cardiovascular-respiratory and alimentary interoception. Finally, he discusses several related areas of research and theory including drug state issues, interoception and psychiatric disorders, and bodily consciousness, and suggests directions for future investigation. The book will be of interest to scientists in neurobiology, psychology, and brain imaging, to indivuals in related clinical fields such as psychiatry, neurology, cardiology, gastroenterology, and clinical psychology, and to their students and trainees.

BackgroundDepression is a serious mental disorder often accompanied by emotional and physiological disorders. Visceral fat index is the current standard method in the evaluation of visceral fat deposition. In this study, we explored the association between VAI and depression in the American population using NHANES data.MethodsA total of 2,577 patients were enrolled for this study. Data were collected through structured questionnaires. Subgroup analysis for the relationship between VAI and depression was evaluated using multivariate regression analysis after adjustment for (...) potential confounding factors.ResultsFor every 1 unit increase in VAI, the clinical depression increased by 14%. High VAI scores increased the highest risk of developing depression. Subgroup analysis demonstrated a strong and stable association between VAI and the development of depression.ConclusionOur study showed that depressive symptoms are associated with a high ratio of visceral adiposity index after controlling confounding factors.

My commentary on mcmahon addresses the fact that only peripheral data have been considered for explaining differential sensibility in somato- and viscerosensory systems. This fails to take it into account that central processing for visceral and somatic inputs is now known to depend on different functional pathways. My commentary on berkley points out that the hypothalamus-pituitary axis is more responsive to stress in females than in males.

Based on brain imaging findings, we present a model according to which addiction emerges as an imbalance in the information processing and integration among various brain circuits and functions. The dysfunctions reflect (a) decreased sensitivity of reward circuits, (b) enhanced sensitivity of memory circuits to conditioned expectations to drugs and drug cues, stress reactivity, and (c) negative mood, and a weakened control circuit. Although initial experimentation with a drug of abuse is largely a voluntary behavior, continued drug use can (...) eventually impair neuronal circuits in the brain that are involved in free will, turning drug use into an automatic compulsive behavior. The ability of addictive drugs to co‐opt neurotransmitter signals between neurons (including dopamine, glutamate, and GABA) modifies the function of different neuronal circuits, which begin to falter at different stages of an addiction trajectory. Upon exposure to the drug, drug cues or stress this results in unrestrained hyperactivation of the motivation/drive circuit that results in the compulsive drug intake that characterizes addiction.

According to the reward-prediction error hypothesis of dopamine, the phasic activity of dopaminergic neurons in the midbrain signals a discrepancy between the predicted and currently experienced reward of a particular event. It can be claimed that this hypothesis is deep, elegant and beautiful, representing one of the largest successes of computational neuroscience. This paper examines this claim, making two contributions to existing literature. First, it draws a comprehensive historical account of the main steps that led to the formulation (...) and subsequent success of the RPEH. Second, in light of this historical account, it explains in which sense the RPEH is explanatory and under which conditions it can be justifiably deemed deeper than the incentive salience hypothesis of dopamine, which is arguably the most prominent contemporary alternative to the RPEH.

This paper addresses psychological factors that might interfere with informed consent on the part of stable patients as potential early-phase clinical trial participants. Thirty-six semistructured interviews with patients who had either diabetes or gout were conducted. We investigated stable patients’ attitudes towards participating in a fictitious first-in-human trial of a novel intervention. We focused on an in-depth analysis of those statements and explanations that indicated the existence of psychological factors impairing decision-making capacity. Three main themes emerged: insufficient comprehension of the (...) inherent logic of clinical trials, the recourse to trust over comprehension, and visceral factors that override deliberative process. Overall, our results indicate a limited psychological capacity on the part of stable patients to meet the requirements of informed consent as set by Declaration of Helsinki. A redesigned informed consent procedure should take account of these psychological realities. (shrink)

Systems of logico-probabilistic reasoning characterize inference from conditional assertions that express high conditional probabilities. In this paper we investigate four prominent LP systems, the systems _O, P_, _Z_, and _QC_. These systems differ in the number of inferences they licence _. LP systems that license more inferences enjoy the possible reward of deriving more true and informative conclusions, but with this possible reward comes the risk of drawing more false or uninformative conclusions. In the first part of the (...) paper, we present the four systems and extend each of them by theorems that allow one to compute almost-tight lower-probability-bounds for the conclusion of an inference, given lower-probability-bounds for its premises. In the second part of the paper, we investigate by means of computer simulations which of the four systems provides the best balance of reward versus risk. Our results suggest that system _Z_ offers the best balance. (shrink)

People differ in the extent to which they discount the values of future rewards. Behavioural economists measure these differences in terms of functions that describe rates of reduced valuation in the future – temporal discounting – as these vary with time. They measure differences in preference for risk – differing rates of probability discounting – in terms of similar functions that describe reduced valuation of rewards as the probability of their delivery falls. So-called ‘impulsive’ people, including people disposed to addiction, (...) tend to choose rewards in patterns that are described by unusually steeply sloped discount functions. The empirical literature is ambivalent as to whether this applies to pathological gamblers (PGs) who manifest most other behavioural patterns associated with addiction, with different, equally careful studies suggesting opposite conclusions (Petry & Casarella 1999; Holt, Green & Myerson 2003). This puzzle may arise from the fact that most previous experiments on discounting behaviour were not designed so as to allow effects of high temporal discounting to be distinguished from effects of low probability discounting. (Addiction has sometimes been associated with the latter because it seems to involve, at least in the starting addict, under appreciation of risk.) Our research project investigates both forms of discounting behaviour and their relationship to severity of risk of PG in a community sample of South African gamblers. (shrink)

Can humans get arbitrarily capable reinforcement learning agents to do their bidding? Or will sufficiently capable RL agents always find ways to bypass their intended objectives by shortcutting their reward signal? This question impacts how far RL can be scaled, and whether alternative paradigms must be developed in order to build safe artificial general intelligence. In this paper, we study when an RL agent has an instrumental goal to tamper with its reward process, and describe design principles that (...) prevent instrumental goals for two different types of reward tampering. Combined, the design principles can prevent reward tampering from being an instrumental goal. The analysis benefits from causal influence diagrams to provide intuitive yet precise formalizations.

The experience of a reward appears to enhance memory for recent prior events, adaptively making that information more available to guide future decision-making. Here, we tested whether reward enhances memory for associative item-location information and also whether the effect of reward spreads to other categorically-related but unrewarded items. Participants earned either points (Experiment 1) or money (Experiment 2) through a time-estimation reward task, during which stimuli-location pairings around a 2D-ring were shown followed by either high-value or (...) low-value rewards. All stimuli were then tested for location memory or recognition (yes/no), immediately and after a 24-hour delay. Across both experiments (combined analysis), there was a robust improvement in location memory following high-value rewards, even though evidence supporting this effect was reliable in Experiment 2 but not in Experiment 1. The memory-enhancing effect of reward was observed on both the immediate and delayed location-memory tests. Reward-enhanced memory for both directly rewarded stimuli and categorically related stimuli that were not directly rewarded. No reliable effect of reward value on yes/no recognition-memory performance was observed in either experiment. We hypothesise that reward enhances the consolidation of recent experience and conceptually related memories to make these more available for future decisions. (shrink)

Reward and punishment sensitivity seem important traits in understanding behavior in general and psychopathology in particular. Though the definitions used for reward and punishment sensitivity differentiate between responsivity and motivation, the measures thus far used to assess these constructs do not. Further, specificity of the type of reward and punishment in questionnaires might result in measurement bias especially when examining the relationship with psychopathology. Therefore, we developed a stimulus-independent multidimensional questionnaire of reward and punishment sensitivity that (...) differentiates between responsivity and motivation. This study addresses the psychometric qualities of this newly developed reward and punishment responsivity and motivation questionnaire. On the basis of exploratory ordinal factor analysis that was used to examine the quality of the initial pool of 39 items, the number of items was reduced to 18. Confirmatory ordinal factor analysis on the remaining items in an independent sample supported a 18-item four-factor model, and showed acceptable to good internal reliability. The relationship between the subscales of the RPRM-Q and often used questionnaires was examined in the combined sample, which showed some first support for the ability of the new questionnaire to differentiate between responsivity and motivation to approach/avoid. The findings indicate that the RPRM-Q might be a helpful instrument to further test the relevance of punishment and reward sensitivity in psychopathology. (shrink)

Humans expect resources to be distributed fairly. They also show biases to construe all acts as intentional. This study investigates whether every unequal distribution is initially assumed to be intentional unfairness. Study 1 presents a control group of adults with a movie showing one individual accidentally receiving less reward than expected for a task. The experimental group was shown the same scenario, except that the individual was now in the presence of an additional person who received the full (...) class='Hi'>reward. Despite the similarity of the scenarios, as predicted, participants in the control condition responded as if the disappointing reward was accidental, while those in the experimental condition responded as if the act was intentional: Their tendency to avoid the “perpetrator” did not differ from that of participants in another control condition who saw an intentionally unfair reward distribution. In Study 2, 7- and 8-year-old children’s results replicated those of adults. Implications for social and moral cognition are discussed. (shrink)

In the absence of explicit punitive sanctions, why do individuals voluntarily participate in intergroup warfare when doing so incurs a mortality risk? Here we consider the motivation of individuals for participating in warfare. We hypothesize that in addition to other considerations, individuals are incentivized by the possibility of rewards. We test a prediction of this “cultural rewards war-risk hypothesis” with ethnographic literature on warfare in small-scale societies. We find that a greater number of benefits from warfare is associated with a (...) higher rate of death from conflict. This provides preliminary support for the relationship between rewards and participation in warfare. (shrink)

University of Oslo and Norwegian School of Economics and Business Administration, Norway We look at how one should reward effort without rewarding talent. One way to approach this issue is to ask how an increase in one individual's effort should be allowed to affect the post-tax income of others.

Key Words: reward • effort • responsibility • equal opportunity (...) • distributive justice. (shrink)

For Tamsin Lorraine, the works of Luce Irigaray and Gilles Deleuze open up new ways of thinking about subjectivity. Focusing on the affinities between the theorists' views—while addressing weaknesses of each—she offers both a cogent analysis of their often challenging writings on this topic and an accessible introduction to their philosophical projects. Through her readings she articulates an approach to subjectivity as an embodied, dynamic process, one that speaks to beliefs about personal identity as well as to the practical problems (...) people face in their relations with one another.Lorraine begins by distinguishing between "conceptual" and "corporeal" considerations of subjectivity and by reviewing recent interdisciplinary efforts to theorize the body. She then turns to Irigaray and Deleuze, finding in the former's notion of the "feminine other" and in the latter's, unique conceptions of nomadic thinking inspiration for a model designed to overcome mind/body dualisms. Her analysis of Irigaray and Deleuze suggests a conception of humanity which amounts to a visceral philosophy—a way of thinking that is receptive to the fluxes of dynamic life forces. (shrink)

At a meeting shortly before his death, Malcolm X was asked by a young white listener: “What contribution can youth, especially students who are disgusted with racism, make to the black struggle for freedom?” Malcolm X's reply has become a familiar one: “Whites who are sincere should organize among themselves and figure out some strategy to break down prejudice that exists in white communities.… This has never been done.”.

The moral sentiments adumbrated by Adam Smith and Charles Darwin reflect some of our basic social appraisals of each other. One set of moral appraisals reflects disgust and withdrawal, a form of contempt. Another set of moral appraisals reflects active concern responses, an appreciation of the experiences (sympathy for some- one)of other individuals and approach related behaviors. While no one set of neural structures is designed for only moral appraisals, a diverse set of neural regions that include the gustatory/visceral (...) neural axis, basal ganglia and iverse neocortical sites underlie moral judgment.

When faced with intertemporal choices, which have consequences that unfold over time, we often discount the future, preferring smaller immediate rewards often at the expense of long-term benefits. How psychologically connected one feels to one’s future self-influences such temporal discounting. Psychological connectedness consists in sharing psychological properties with past or future selves, but connectedness comes in degrees. If one feels that one is not psychologically connected to one’s future self, one views that self like a different person and is less (...) likely to wait for the future reward. Increasing perceived psychological connectedness to one’s future self may lead to more far-sighted decisions. Episodic prospection may help in this regard. Episodic prospection is our ability to ‘pre-experience’ the future by mentally simulating it, drawing on information from episodic memory and other sources. Episodic memory and prospection are thought to involve a special form of consciousness, which underpins the capacity to appreciate the connection between one’s past, present, and future selves. Simulating the future self through prospection may increase felt psychological connectedness and support future-oriented decision-making. Yet this is where a puzzle arises. The imagery of episodic memory and prospection is perspectival: often one views the visualised scenario from a detached perspective, seeing oneself from-the-outside as if viewing another person. The aim of this paper is to characterise how the perspectival imagery of prospection relates to psychological connectedness, and to show that even though such imagery involves a detached perspective it can still be used to help reward one’s future self.

Rewards are reinforcement mechanisms that organizations use to shape desirable employee behaviors. However, rewards may also have unintended consequences, such as building expectations for receiving extra benefits and weakening employee barriers to unethical acts. This article investigates the dark side of the reward–behavior association, and exploring what is referred to as the reward–theft parity effect (RTPE). The authors hypothesize that receiving rewards induces a corresponding type of theft. In Study 1, survey results (n = 634) show initial support (...) for the RTPE between rewards and same‐category theft, and that perceptions of procedural justice attenuate this association. Study 2 involved a 2 (reward) × 2 (theft opportunity) between‐subjects experimental design (n = 300) and provides further support for the RTPE by revealing greater theft under a reward–theft parity condition than under a reward–theft disparity condition. Study 3 replicates these findings in a field experiment (n = 285) and finds that the RTPE is exacerbated when the reward–behavior task is perceived as unjust. Collectively, these findings provide new theoretical insights while also giving managers a more complete understanding of the dark side of behavioral reinforcement mechanisms. (shrink)

In 1929 when Aurel Kolnai published his essay “On Disgust” in Husserl's ]ahrbuch he could truly assert that disgust was a "sorely neglected" topic.

We here provide an account of Kolnai’s contribution to the study of the phenomenon of disgust, of his general theory (...) of emotions and of the phenomenological methodology he employed in his work.

While it is known that reward induces attentional prioritization, it is not clear what effect reward-learning has when associated with stimuli that are not fully perceived. The masked priming paradigm has been extensively used to investigate the indirect impact of brief stimuli on response behavior. Interestingly, the effect of masked primes is observed even when participants choose their responses freely. While classical theories assume this process to be automatic, recent studies have provided evidence for attentional modulations of masked (...) priming effects. Most such studies have manipulated bottom-up or top-down modes of attentional selection, but the role of “newer” forms of attentional control such as reward-learning and selection history remains unclear. In two experiments, with number and arrow primes, we examined whether reward-mediated attentional selection modulates masked priming when responses are chosen freely. In both experiments, we observed that primes associated with high-reward lead to enhanced free-choice priming compared to primes associated with no-reward. The effect was seen on both proportion of choices and response times, and was more evident in the faster responses. In the slower responses, the effect was diminished. Our study adds to the growing literature showing the susceptibility of masked priming to factors related to attention and executive control. (shrink)

Studies suggest that reward and emotion are interdependent. However, there are discrepancies regarding the interaction between these variables. Some researchers speculate that the inconsistent findings may be due to different targets being used. Although reward and emotion both affect attention, it is not clear whether their impacts are independent. This study examined the impact of reward anticipation on emotion processing for different targets. A cue-target paradigm was used, and behavior and eye-tracking data were recorded in an emotion (...) or sex recognition task under the conditions of reward and non-reward anticipation. The results showed that when the target was related to the emotional attribute of the stimulus, the reward promoted the processing target information, thereby generating reward-oriented attention. When the target was unrelated to the emotional attributes of the stimulus, the reward did not promote the processing target information, and at the same time, individuals had negative emotional biases toward the emotional faces. The results revealed that, in addition to affecting the attention to emotional faces independently, the target regulated the promotion of reward anticipation to emotional attention and attention bias towards negative stimuli.

Research on academic pay finds an unexplained gender pay gap that has not fully dissolved over time and that appears to increase with years of experience. In this study, I consider how role congruity bias contributes to this pay gap. Bias is more likely to manifest in a context where there is some ambiguity about performance and where stereotypes are stronger. I predict that bias in the attribution of credit for coauthored research leads to lower returns to research for female (...) professors. To test this prediction, I use a sample of Canadian faculty in accounting, where research is typically coauthored, where females are underrepresented at the most senior ranks, and where many universities evaluate merit in research, teaching, and service to determine salary increases. In regressions of salary on individual and institutional determinants of salary, I find that women earn marginally less than men. However, the pay gap is only evident for women who publish in a selective list of journals; for the subset of faculty with no publications from this list, there are no significant differences in salary. For researching faculty, the pay gap relates specifically to research productivity. While women publish less on average than men, the returns to their research are also lower. In particular, the relation between the individual’s research ranking and salary is significantly lower for women who publish a higher proportion of their work with men, than for all other faculty. Additional analysis of salary and coauthor patterns confirms that women receive significantly less credit for coauthored articles they publish with men than those they publish with other women but that no similar variations in reward are evident for men across publishing patterns. These findings suggest bias in the attribution of credit for coauthored research in the determination of salary, consistent with role congruity theory, and provide an important potential explanation for why salaries for women vary systematically from those of men even after considering productivity. Providing lower rewards for equal work represents a continuing ethical issue in academe and compounds the challenges women already facing in the profession. (shrink)

Feminist philosophers of technoscience have long argued that it is vital that we question biomedical and scientific claims to an immaterial and disembodied objectivity, and also, more specifically, that we disable the conception of medical visualising technologies as neutral or transparent conduits to the “fact” of the body. In this paper we suggest that corporeal feminism is well situated to provide such a critique. Feminist phenomenologists over the past decade have theorised embodiment in a number of critical ways, many deriving (...) concepts from the work of Merleau-Ponty, and emphasising the pliability and diversity of our body images and corporeal schematics. Others such as Elizabeth Wilson, Cathy Waldby and Drew Leder have considered the interdependence of our inner biology or viscerality with the socio-cultural inscriptions of embodiment. In this paper, these adaptations of phenomenology, and their account of the specificity and depth of embodied being, will be discussed and applied to the discourse of biomedicine and the apparatus of magnetic resonance imaging (MRI).

The brain and emotion treats emotions as states elicited by reinforcers (reward or punishment), but it is unclear how this view can do justice to the diversity of emotions. It is also unclear how such a view distinguishes emotions from states such as hunger and thirst. A complementary approach to understanding emotions may begin by considering emotions as aspects of social cognition.

Rewards research typically examines how well incentives increase employees' productivity. By comparison, research in business ethics research focuses more on employees' ethical behavior than on their productivity per se. Yet, despite the bounty of literature in these two areas, little research specifically (a) links incentives to (un)ethical behavior and (b) focuses on relationships other than that between the employee-employer.

In philosophy, the textbook case for the discussion of human motivation is the examination (and almost always, the refutation) of psychological egoism. The arguments have become part of the folklore of our tribe, from their inclusion in countless introductory texts.

Although I am inclined at present to put my bets on the reward-event theory, with its internalism, monism, (...) and causal primacy of satisfaction, I think we are very far from knowing enough to settle these questions concerning motivation, human or otherwise.

A developing neurobiological/psychological theory of positive motivation gives a key causal role to reward events in the brain which can be directly activated by electrical stimulation (ESB). In its strongest form, this Reward Event Theory (RET) claims that all positive motivation, primary and learned, is functionally dependent on these reward events. Some of the empirical evidence is reviewed which either supports or challenges RET. The paper examines the implications of RET for the concepts of 'motivation', 'desire' and (...) 'reward' or 'pleasure'. It is argued (1) that a 'causal base' as opposed to a functional' concept of motivation has theoretical advantages; (2) that a causal distinction between the focus' and the 'anchor' of desire suggests an ineliminable 'opacity' of desire; and (3) that some affective concept, such as 'pleasure', should play a key role in psychological explanation, distinct from that of motivational (or cognitive) concepts. A concept of 'reward' or 'pleasure' as intrinsically positive affect is defended, and contrasted with the more 'operational' definitions of 'reward' in some of the hypotheses of Roy Wise. (shrink)

This qualitative study of 27 women animal activists examines the risks and rewards that accompany a commitment to animal rights activism. One of the common beliefs about animal rights activists is that their political choices are fanatic and unyielding, resulting in rigid self-denial. Contrary to this notion, the women in this study experienced both the pain and the joy of their transformation toward animal activism. Activism took an enormous toll on their personal relationships, careers, and emotional well being. They struggled (...) as friendships ended and family relationships suffered; some experienced harassment and abuse as a result of their efforts. Yet the women were just as likely to extol the rewards and pleasure gained from their participation in the cause of animal liberation. These included a heightened awareness of political issues, greater self-confidence, the feeling that they were making a difference in the world, and the joy of living a “more meaningful life.”.

In this paper, we raise and discuss a puzzle about the relationships among goods, reasons, and deontic status. Suppose you have it within your power to give someone something they would enjoy. The following claims seem platitudinous: you can use this power to reward whatever kind of option you want, thereby making that option better and generating a reason for that person to perform it; this reason is then weighed alongside and against the other reasons at play; and altogether, (...) the reasons determine the deontic statuses of that person’s options. We show, however, that in a certain class of cases at least one of these apparent platitudes must be false. In particular, we show that in a certain kind of case wrongfulness cannot be rewarded. In some cases, if one tries to reward wrongfulness, something surprising must go awry: either what you attempt to give as a reward would not, in fact, be good, or it would not generate a reason, or it would have a surprising effect on the deontic status of the relevant options. The upshot is that the relationships among goods, reasons, and deontic status are complicated in ways that have not previously been remarked. (shrink)

This paper is situated in the context of feminist poststructuralist debates around identity. In it, I argue that anti-essentialist accounts of identity, while they may displace, or at least call into question, the foundations of subjectivity, are no less likely to invoke a series of presuppositions with respect to the self than those who seek to maintain them in some form. In particular, these presuppositions often cohere around the materiality of the body. And yet, paradoxically, this accent on materiality refers (...) to a very particular kind of body - one that seems to have very little relation to the biological body. Using psychopharmacology as an example, I suggest that the Gilles Deleuze's ethology offers one way through which both to engage seriously with the 'biological' body while at the same time resisting either an essentialist or biological determinist position.

The audit profession’s technical and ethical standards require the application of professional skepticism throughout the financial statement audit process, as auditor skepticism is essential for detecting financial statement fraud and protecting the investing public. However, recent research suggests that audit supervisors often punish staff for exercising skepticism, presenting auditors with an ethical conflict between acting in their own self-interest and acting in a way that improves audit quality and protects the public. This research also suggests that supervisors who reward (...) appropriate skeptical behavior, regardless of the outcome, appear to develop staff that are more likely to detect and convey fraud red flags to their superiors. Building on this research, we use a case-based survey to identify the characteristics of audit supervisors (audit seniors and managers) who are more likely to reward appropriate skepticism, even if it ultimately does not identify a misstatement. We find that trait skepticism, especially suspending one’s judgment, positively drives the evaluations of professional skepticism in our setting. Also, we observe that when supervisors believe that their own audit partner will view the skepticism favorably, they “pay it forward” by rewarding their own staff who engage in skepticism. Our findings identify the characteristics that audit firms may want to develop and foster in auditors rising to supervisory levels. (shrink)
