The present research was designed to test whether the subjective experience of more effort related to more reward valuation as measured by a neural response. This prediction was derived from the theory of cognitive dissonance and its effort justification paradigm. Young adult participants (n = 82) engaged in multiple trails of a low or high effort task that resulted in a loss or reward on each trial. Neural responses to the reward (loss) cue were measured using EEG, (...) so that the event-related potential known as the Reward Positivity (RewP) could be assessed. Results revealed no significant differences between low and high effort conditions on the RewP. However, within the high effort condition, a more subjective experience of effort was associated with a larger RewP. This research extends past research on the effort justification paradigm of cognitive dissonance theory by suggesting that effort justification is associated with an implicit measure of reward valuation. It therefore challenges recent perspectives on dissonance processes that posit that these evaluative changes should only occur on explicit but not implicit measures. (shrink)

Background: Mental healthcare needs person-tailored interventions. Experience Sampling Method (ESM) can provide daily life monitoring of personal experiences. This study aims to operationalize and test a measure of momentary reward-related Quality of Life (rQoL). Intuitively, quality of life improves by spending more time on rewarding experiences. ESM clinical interventions can use this information to coach patients to find a realistic, optimal balance of positive experiences (maximize reward) in daily life. rQoL combines the frequency of engaging in a relevant (...) context (a ‘behavior setting’) with concurrent (positive) affect. High rQoL occurs when the most frequent behavior settings are combined with positive affect or infrequent behavior settings co-occur with low positive affect. Methods: Resampling procedures (Monte Carlo experiments) were applied to assess the reliability of rQoL using various behavior setting definitions under different sampling circumstances, for real or virtual subjects with low-, average- and high contextual variability. Furthermore, resampling was used to assess whether rQoL is a distinct concept from positive affect. Virtual ESM beep datasets were extracted from 1058 valid ESM observations for virtual and real subjects. Results: Behavior settings defined by Who-What contextual information were most informative. Simulations of at least 100 ESM observations are needed for reliable assessment. Virtual ESM beep datasets of a real subject can be defined by Who-What-Where behavior setting combinations. Large sample sizes are necessary for reliable rQoL assessments, except for subjects with low contextual variability. rQoL is distinct from positive affect. Conclusion: rQoL is a feasible concept. Monte Carlo experiments should be used to assess the reliable implementation of an ESM statistic. Future research in ESM should asses the behavior of summary statistics under different sampling situations. This exploration is especially relevant in clinical implementation, where often only small datasets are available. (shrink)

Organizational citizenship behavior can foster organizational competitiveness and survival especially, facing a rapidly changing environment. There are some empirical pieces of research that shed light on the effects of OCB on extrinsic rewards, since OCB, through performance appraisal, affects extrinsic rewards which will influence OCB as well. However, researchers have overlooked the reverse effect of extrinsic rewards on OCB. It is necessary to explore the mechanism between positive verbal rewards and OCB. This study integrated psychological ownership and affective commitment to (...) form a structural model based on social exchange theory and cognitive evaluation theory. These results show that positive verbal rewards are positively correlated with psychological ownership, psychological ownership is positively correlated with affective commitment and OCB, and affective commitment is positively correlated with OCB. As refers to the mediating effects, psychological ownership fully mediates the relationship between positive verbal rewards and affective commitment. Furthermore, affective commitment plays a partial mediating role in the effect of psychological ownership on OCB. Accordingly, this psychological mechanism between positive verbal rewards and OCB reveals important theoretical and practical implications. (shrink)

This study explores positive migrant storytelling in non-governmental organizations’ advocacy campaigns. We focus on the practices and implications of leveraging storytelling towards charity organizations’ institutional goals. Drawing upon critical discourse studies and narrative studies, we propose a critical storytelling approach that pays attention to the specific nature of storytelling as a discourse practice in itself. We focus on a UNHCR human-interest story of refugee displacement and subsequent integration into the UK. We employ the heuristic concept of positioning that calls for (...) analysis at different, though interrelated levels of narrative activity, to explore how affect is mobilized and the specific identity categories and affect types that are created for migrants and their hosts. We then situate these identity positions in wider dominant discourses of migrant integration. We show that the story foregrounds emblematic refugees, worthy of hosts’ support as well as relationships of dependence between migrants and the host society as requisites to successful integration. We argue that the ways in which an individual refugee story gets mobilized as an exemplary story reveals canonized forms of positive migrant storytelling emerging in the UK context that end up invoking dominant power asymmetries in relation to migration and British integration.

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)

Using a new method, we examined whether incidental perception of need-rewarding (positive) objects unintentionally prepares motor action. Participants who varied in their level of need for water were presented with glasses of water (and control objects) that were accompanied by go and no-go cues that required a response (key-press) or withholding a response. Importantly, if need-rewarding objects unintentionally prepare action, presentation of no-go cues should lead to motor inhibition of these prepared motor impulses. Consistent with this hypothesis, results showed that (...) participants relatively high in need for water (and hence, who perceive water as a rewarding, positive object) were slower to react to a successive action probe after withholding a response during perception of water than during perception of the control object, suggesting motor inhibition of unintentionally prepared motor impulses. We propose that incidental perception of need-rewarding objects unintentionally potentiates preparation of motor action to these objects. (shrink)

Bonuses, as incentives or rewards for health -related behavior, feature prominently in German social health insurance. Their goal is centered around promoting personal responsibility, but reducing overall health -care expenditure and enabling competition between sickness funds also play a role. The central position of personal responsibility in German health -care policy is described, and a framework is offered for an analysis of the ethical issues raised by policies seeking to promote responsibility. The framework entails seven tests relating to: solidarity; equality (...) and equity; intrusiveness; attributability and opportunity of choice; evidence, rationale, and feasibility; affected third parties; and coherence. It is contended that a focus on tests, in particular from within contractualism, is the most appropriate way of addressing the question of health responsibility in pluralistic societies. However, taken by themselves, the tests also allow an identification of the key ethical issues by particular policies, which are illustrated by applying the framework to particular bonus polices.

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)

Contingent reinforcement behavior is generally regarded as one of the key elements of being a “good” leader, yet the question of what happens when this behavior is absent has received little attention in past empirical research. Drawing upon self-regulation theory, we develop and test a model that specifies the effects of leader reward omission on employes’ deviant behavior. Using the data of 230 workers from two manufacturing companies located in South China collected across three time points, we find that (...) leader reward omission is positively associated with deviant behavior. Moreover, the indirect effects of leader reward omission on employes’ deviant behavior are mediated by moral disengagement. Our study also reveals that Machiavellianism can aggravate the positive effect of leader reward omission on moral disengagement, and subsequently exacerbate the indirect effect on employes’ deviant behavior. Taken together, our findings reveal the consequences of leader reward omission, and the importance of examining subordinate self-regulation under the lack of positive reinforcement. (shrink)

ObjectivePhysical isolation measures, known as lockdown or shelter-in-place, experienced during coronavirus disease 2019 have the potential to cause psychological distress. This study was conducted to examine parents’ perceived stress and whether reports of rewards and challenges during lockdown impact stress.MethodsData were collected using a cross-sectional online survey in New South Wales, Australia, across the 4-week lockdown. The survey was completed by 158 parents of children aged under 6 years. Stress was measured using the short form of the Perceived Stress Scale. (...) Rewards and challenges were reported in response to two open-ended questions.ResultsThere was a weak negative correlation between PSS-4 scores and days in isolation, with parents who had spent longer in isolation reporting fewer stress symptoms. The relationship between time in isolation and stress was moderated by the degree to which parents described more rewards than challenges: parents who perceived high rewards and low challenges reported lower PSS-4 scores with more days in lockdown, whereas parents who perceived low rewards and high challenges reported higher PSS-4 scores with more days in lockdown. The moderation model examining associations between time in isolation and rewards ratio explained 13% of the variance in PSS-4 scores.ConclusionLockdowns are not uniformly or consistently negative experiences for parents. Identifying positive aspects of the experience may serve to buffer negative mental health risks across time. Understanding resilience strategies is critical for supporting current psychological wellbeing and to adequately prepare for future pandemic experiences. (shrink)

RÉSUMÉDans Scientific Ontology: Integrating Naturalized Metaphysics and Voluntarist Epistemology, je soutiens que les convictions ontologiques associées à la recherche scientifique sont imprégnées de convictions philosophiques. Les interprétations de l'ontologie scientifique impliquent ce que j'appelle des inférences métaphysiques et, qui plus est, il existe différentes façons de faire ces inférences sur la base de positions épistémiques différentes, mais néanmoins rationnelles. Si cette analyse est juste, elle problématise toute distinction nette entre la métaphysique naturalisée et les autres types de métaphysique, et dissout (...) toute présomption qu'il existe une seule bonne réponse aux questions ontologiques liées aux sciences. Dans cet article, je considère quelques-uns des importants défis qu'Amanda Bryant, Stathis Psillos et Matthew Slater posent à l'endroit de ces affirmations. (shrink)

What motivates behavior? What are the qualities of experience which make life worth living? Taking a new interdisciplinary approach, Morillo advances the theory that pleasure—interpreted as a distinct, separable, noncognitive quality of experience—is essential for all positive motivation and is the only intrinsic, nonmoral good in the lives of human beings and many other sentient creatures. Morillo supports her arguments with recent neuropsychological evidence concerning the role of reward centers in the brain and philosophical arguments for a naturalistic theory (...) of value and the good life. "Contingent Creatures" will interest philosophers, psychologists, and neurobiologists. (shrink)

Most work in neo-Aristotelian virtue ethics begins by supposing that the virtues are the traits of character that make us good people. Secondary questions, then, include whether, why, and in what ways the virtues are good for the people who have them. This essay is an argument that the neo-Aristotelian approach is upside down. If, instead, we begin by asking what collection of character traits are good for us---that is, what collection of traits are most likely to promote our own (...) well-being---we find a collection of traits a lot like the traditional slate of virtues. This suggests an egoistic theory of the virtues: the virtues just are those traits of character that reliably promote the well-being of their possessor. In addition to making the positive case for character egoism, I defend it from anticipated objections. I argue that character egoism doesn't inherit the problems of ethical egoism, and conclude by offering character-egoist accounts of two virtues traditionally thought to be fundamentally other-regarding: honesty and justice.

Public health policies typically assume that there are characteristics and constraints over health that an individual cannot control and that there are choices that an individual could change if he is nudged or provided with incentives. We consider that health is determined by a range of personal, social, economic and environmental factors and we discuss to what extent an individual can control these factors. In particular, we assume that the observed health status of an individual is a result of factors (...) within the individual’s control and constraints the individual faces. We suggest three different constraints: budget, time and psychological constraints and position various determinants of health according to increasing levels of constraint and increasing degrees of individual control. We finally discuss public health policies such as nudging, intervening and rewarding within this new framework and show that the level of constraints and the degree of individual control on health status are essential dimensions to consider when designing and implementing public health policies.

Purpose - The aim of this research was to investigate the effect of transformational leadership and transactional contingent reward as complementary, but distinct, forms of leadership on facets of organizational identification via the perception of innovation and goal organizational values. Design/methodology/approach – Three studies were carried out implementing either a measurement of mediation or experimental-causal-chain design to test for the hypothesized effects. Findings - The measurement of mediation study showed that transformational leadership had a positive direct and indirect effect, (...) via innovation value orientation, on cognitive identification, whereas transactional contingent reward was more strongly related to affective, rather than cognitive, identification, and goal orientation was a mediator of their link. The findings of the two experimental-causal-chain studies further supported the hypothesized effects. Transformational leadership was found to lead subordinates to perceive the culture as more innovative compared to transactional contingent reward, whereas transactional contingent reward led employees to perceive the culture as more goal, than innovation, oriented. Finally, innovation, compared to goal, value orientation increased cognitive identification, while goal orientation facilitated affective, rather than cognitive, identification. Implications - The practical implications involve the development of strategies organizations can apply, such as leadership training programs, to strengthen their ties with their employees, which, in turn, may have a positive impact on in-role, as well as extra-role, behaviors. Originality/Value – The originality of this research concerns the identification of distinct mechanisms explaining the effect of transformational leadership and transactional contingent reward on cognitive and affective identification applying an organizational culture perspective and a combination of measurement and causal mediation designs.

A vision of a living code of ethics is proposed to counter the emphasis on negative phenomena in the study of organizational ethics. The living code results from the harmonious interaction of authentic leadership, five key organizational processes (attraction–selection–attrition, socialization, reward systems, decision-making and organizational learning), and an ethical organizational culture (characterized by heightened levels of ethical awareness and a positive climate regarding ethics). The living code is the cognitive, affective, and behavioral manifestation of an ethical organizational identity. We (...) draw on business ethics literature, positive organizational scholarship, and management literature to outline the elements of positive ethical organizations as those exemplary organizations consistently practicing the highest levels of organizational ethics. In a positive ethical organization, the right thing to do is the only thing to do. (shrink)

Kindergarten teachers' engagement in work is influenced by many factors. Total rewards perceptions, as an individual's evaluation of the rewards provided by the organization, may promote work engagement when it can meet their intrinsic and extrinsic work demands. To explore the relationship between kindergarten teachers' total rewards perceptions and work engagement, and the mediating role of organizational identification, a survey was conducted among 1,014 kindergarten teachers applying the Chinese versions of the Total Rewards Perceptions Scale for Kindergarten Teacher, Kindergarten Teacher (...) Organizational Identification Scale, and Kindergarten Teacher Work Engagement Scale. The results showed that kindergarten teachers' total rewards perceptions and its four factors were positively correlated with organizational identification and work engagement. Organizational identification was positively related to work engagement. Organizational identification partially mediated the relationship between total rewards perception and work engagement among kindergarten teachers. We discussed the result of the relationship between total rewards perceptions, organizational identification, and work engagement among Chinese kindergarten teachers. (shrink)

Bioinformatics – the so-called shotgun marriage between biology and computer science – is an interdiscipline. Despite interdisciplinarity being seen as a virtue, for having the capacity to solve complex problems and foster innovation, it has the potential to place projects and people in anomalous categories. For example, valorised ‘outputs’ in academia are often defined and rewarded by discipline. Bioinformatics, as an interdisciplinary bricolage, incorporates experts from various disciplinary cultures with their own distinct ways of working. Perceived problems of interdisciplinarity include (...) difficulties of making explicit knowledge that is practical, theoretical, or cognitive. But successful interdisciplinary research also depends on an understanding of disciplinary cultures and value systems, often only tacitly understood by members of the communities in question. In bioinformatics, the ‘parent’ disciplines have different value systems; for example, what is considered worthwhile research by computer scientists can be thought of as trivial by biologists, and vice versa. This paper concentrates on the problems of reward and recognition described by scientists working in academic bioinformatics in the United Kingdom. We highlight problems that are a consequence of its cross-cultural make-up, recognising that the mismatches in knowledge in this borderland take place not just at the level of the practical, theoretical, or epistemological, but also at the cultural level too. The trend in big, interdisciplinary science is towards multiple authors on a single paper; in bioinformatics this has created hybrid or fractional scientists who find they are being positioned not just in-between established disciplines but also in-between as middle authors or, worse still, left off papers altogether.

The predictive processing framework posits that people continuously use predictive principles when interacting with, learning from, and interpreting their surroundings. Here, we suggest that the same framework may help explain how people process self-relevant knowledge and maintain a stable and positive self-concept. Specifically, we recast two prominent self-relevant motivations, self-verification and self-enhancement, in predictive processing (PP) terms. We suggest that these self-relevant motivations interact with the self-concept (i.e., priors) to create strong predictions. These predictions, in turn, influence how people interpret (...) information about themselves. In particular, we argue that these strong self-relevant predictions dictate how prediction error, the deviation from the original prediction, is processed. In contrast to many implementations of the PP framework, we suggest that predictions and priors emanating from stable constructs (such as the self-concept) cultivate belief-maintaining, rather than belief-updating, dynamics. Based on recent findings, we also postulate that evidence supporting a predicted model of the self (or interpreted as such) triggers subjective reward responses, potentially reinforcing existing beliefs. Characterizing the role of rewards in self-belief maintenance and reframing self-relevant motivations and rewards in predictive processing terms offers novel insights into how the self is maintained in neurotypical adults, as well as in pathological populations, potentially pointing to therapeutic implications.

In this paper, I examine the way humans interact with domestic companion animals, with a focus on ‘positive reward-based training’ methods, particularly for dogs. From a biosemiotic perspective, I discuss the role of animal training in today’s society and examine what binary reward- based reinforcement schedules communicate, semiotically. I also examine the extent to which reward-based training methods promote better welfare, when compared to the more traditional methods which rely on aversive stimuli and punishment, if and when (...) they are relied upon excessively. I conclude that when used as the primary means of communication, they have the potential to be detrimental to animal welfare, because the underlying social signal is control and resource dominance. As an alternative view to behaviourist-based learning theory and conditioning, I outline how enactivist theories of cognition support a semiotic approach to interspecific human-animal communication. I therefore propose a move toward a dynamic semiosis and mutual understanding based upon Peirce’s phenomenology, resulting in a more balanced merging of Umwelten. The aim is to create rich and more complex semiospheres around humans and domestic animals, which allow for individual agency and autonomy. (shrink)

In this study, we explore the impact of Machiavellian rhetoric on fundraising within the increasingly important context of online crowdfunding. The “all-or-nothing” funding model used by the world’s largest crowdfunding platform, Kickstarter, may be an attractive context in which entrepreneurs can utilize Machiavellian rhetoric to reach their funding goal, lest they get no funding at all. This study uses data from 76,847 crowdfunding projects posted on kickstarter.com and develops a dictionary for computer-aided text analysis (CATA) of Machiavellian rhetoric to measure (...) the relationship between the frequency of Machiavellian rhetoric use and crowdfunding performance, operationalized as either reaching a funding goal or the number of backers who funded the project. Machiavellian rhetoric is segregated into eight facets, which are categorized into hard and soft influence tactics. Hard tactics include revenge, intimidation, betrayal, and manipulation. Soft tactics include ingratiation, supplication, self-disclosure, and persuasion. Results reveal that signals of revenge, self-disclosure, and intimidation have negative effects, whereas signals of ingratiation and persuasion have mixed positive effects on crowdfunding performance. Ingratiation is found to increase the number of backers, but not funding success. Conversely, persuasion is found to increase funding success, but not the number of backers. Surprisingly, betrayal rhetoric is positively related to both measures of crowdfunding performance. Thus, this article complements the literature on backer decision-making, entrepreneurial methods, reward-based crowdfunding, and ethics in entrepreneurship by demonstrating how the displays of potentially negative phenomena, such as Machiavellianism, have complex consequences for entrepreneurial outcomes.

We studied the role of social dynamics in moral decision-making and behavior by investigating how physical sensations of dirtiness versus cleanliness influence moral behavior in leader–subordinate relationships, and whether a leader’s self-interest functions as a boundary condition to this effect. A pilot study (N = 78) revealed that when participants imagined rewarding (vs. punishing) unethical behavior of a subordinate, they felt more dirty. Our main experiment (N = 96) showed that directly manipulating dirtiness by allowing leaders to touch a dirty (...) object (fake poop) led to more positive evaluations of, and higher bonuses for, unethical subordinates than touching a clean object (hygienic hand wipe). This effect, however, only emerged when the subordinate’s unethical behavior did not serve the leader’s own interest. Hence, subtle cues such as bodily sensations can shape moral decision-making and behavior in leader–subordinate relationships, but self-interest, as a core characteristic of interdependence, can override the influence of such cues on the leader’s moral behavior.

Studies have shown that performance‐dependent monetary rewards facilitate visual perception. However, no study has examined whether such a positive effect is limited to the rewarded task or may be generalized to other tasks. In the current study, two groups of people were asked to perform two visual perception tasks, one being a reward‐relevant task and the other being a reward‐irrelevant task. For the reward‐relevant task, the experimental group received performance‐dependent monetary rewards, whereas the control group did not. (...) For the reward‐irrelevant task, both groups were not rewarded. The two tasks were randomly intermixed trial by trial (Experiment 1) or presented block by block (Experiment 2) or session by session (Experiments 3a, 3b, and 3c). Results showed that performance‐dependent monetary rewards improved participants' performance on the relevant task in all experiments and impaired their performance on the irrelevant task in Experiments 2, 3a, 3b, and 3c. These results suggested that monetary rewards might incur a cost on reward‐irrelevant tasks. Finally, the benefit of monetary rewards disappeared when they were no longer provided during the final session. This is the first study that reveals both the bright and dark sides of the performance‐dependent monetary rewards in visual perception. (shrink)

We explore success drivers of reward-based crowdfunding for poverty alleviation in China. The results from our econometric modeling using data from 4375 reward-based crowdfunding campaigns suggest that poverty alleviation campaigns, as compared to ordinary ones, benefit from higher funded amounts, larger backer numbers, and greater success rates. The results also suggest that poverty alleviation campaigns perform better when the products sold originate from poorer (as compared to wealthier) regions and when price premiums are lower (as compared to higher). (...) We corroborate important findings from the field study with an experimental study, showing that the consumer’s feeling of warm glow accounts for the positive effects of poverty alleviation campaigns (as compared to ordinary) campaigns. We expand the applications of warm-glow theory into the context of reward-based crowdfunding campaigns for poverty alleviation and offer new insights into success drivers of such campaigns. (shrink)

Since most research on the topic of experiences related to becoming a psychologist is conducted from a pathogenic paradigm, the study reported in this paper aimed to describe the journey of a clinical master’s student from the perspective of positive psychology. A strengths-based paradigm allowed the researcher and the participant to understand the journey through the lens of personal growth, professional development, coping strategies, and attempts to make sense of the related difficulties. In this study, a qualitative research approach was (...) used and a single case study design was employed. Data analysis followed the procedure of interpretative phenomenological analysis. Themes that were conceptualized and operationalized within the structure of psychological well-being comprised six well-being domains, namely personal growth; purpose in life; autonomy; self-acceptance; positive relationships with others; and environmental mastery. The most prominent finding was that, while the experience of becoming a psychologist is known to be a long and difficult journey, it can also be rewarding and positive, and holds the potential to enhance psychological well-being.

Compared to our understanding of positive prediction error signals occurring due to unexpected reward outcomes, less is known about the neural circuitry in humans that drives negative prediction errors during omission of expected rewards. While classical learning theories such as Rescorla–Wagner or temporal difference learning suggest that both types of prediction errors result from a simple subtraction, there has been recent evidence suggesting that different brain regions provide input to dopamine neurons which contributes to specific components of this prediction (...) error computation. Here, we focus on the brain regions responding to negative prediction error signals, which has been well-established in animal studies to involve a distinct pathway through the lateral habenula. We examine the activity of this pathway in humans, using a conditioned inhibition paradigm with high-resolution functional MRI. First, participants learned to associate a sensory stimulus with reward delivery. Then, reward delivery was omitted whenever this stimulus was presented simultaneously with a different sensory stimulus, the conditioned inhibitor. Both reward presentation and the reward-predictive cue activated midbrain dopamine regions, insula and orbitofrontal cortex. While we found significant activity at an uncorrected threshold for the CI in the habenula, consistent with our predictions, it did not survive correction for multiple comparisons and awaits further replication. Additionally, the pallidum and putamen regions of the basal ganglia showed modulations of activity for the inhibitor that did not survive the corrected threshold. (shrink)

Deep brain stimulation of the subthalamic nucleus is an effective treatment for the motor symptoms of movement disorders including Parkinson's Disease. Despite its therapeutic benefits, STN-DBS has been associated with adverse effects on mood and cognition. Specifically, apathy, which is defined as a loss of motivation, has been reported to emerge or to worsen following STN-DBS. However, it is often challenging to disentangle the effects of STN-DBSper sefrom concurrent reduction of dopamine replacement therapy, from underlying PD pathology or from disease (...) progression. To this end, pre-clinical models allow for the dissociation of each of these factors, and to establish neural substrates underlying the emergence of motivational symptoms following STN-DBS. Here, we performed a systematic analysis of rodent studies assessing the effects of STN-DBS on reward seeking, reward motivation and reward consumption across a variety of behavioral paradigms. We find that STN-DBS decreases reward seeking in the majority of experiments, and we outline how design of the behavioral task and DBS parameters can influence experimental outcomes. While an early hypothesis posited that DBS acts as a “functional lesion,” an analysis of lesions and inhibition of the STN revealed no consistent pattern on reward-related behavior. Thus, we discuss alternative mechanisms that could contribute to the amotivational effects of STN-DBS. We also argue that optogenetic-assisted circuit dissection could yield important insight into the effects of the STN on motivated behavior in health and disease. Understanding the mechanisms underlying the effects of STN-DBS on motivated behavior-will be critical for optimizing the clinical application of STN-DBS. (shrink)

In order to improve our understanding of the components that reflect functionally important processes during reward anticipation and consumption, we used principle components analyses (PCA) to separate and quantify averaged ERP data obtained from each stage of a modified monetary incentive delay (MID) task. Although a small number of recent ERP studies have reported that reward and loss cues potentiate ERPs during anticipation, action preparation, and consummatory stages of reward processing, these findings are inconsistent due to temporal (...) and spatial overlap between the relevant electrophysiological components. Our results show three components following cue presentation are sensitive to incentive cues (N1, P3a, P3b). In contrast to previous research, reward‐related enhancement occurred only in the P3b, with earlier components more sensitive to break‐even and loss cues. During feedback anticipation, we observed a lateralized centroparietal negativity that was sensitive to response hand but not cue type. We also show that use of PCA on ERPs reflecting reward consumption successfully separates the reward positivity from the independently modulated feedback‐P3. Last, we observe for the first time a new reward consumption component: a late negativity distributed over the left frontal pole. This component appears to be sensitive to response hand, especially in the context of monetary gain. These results illustrate that the time course and sensitivities of electrophysiological activity that follows incentive cues do not follow a simple heuristic in which reward incentive cues produce enhanced activity at all stages and substages.

Several recent studies have found that when the other’s gain is greater, even subjects’ reward may seem like a loss and lead to a negative experience. These studies indicate the complexity of reward evaluation in the context of social comparison. The satisfaction rating of reward outcome not only depends on objective social comparison but also on subjective evaluation. However, less is known about the neural time course of subjective evaluation. Therefore, we employed a 2 × 2 within-subjects (...) factorial design, in which we manipulated the reward distribution for the subjects. Electroencephalography responses were recorded, while two subjects concurrently but independently performed a simple dot-estimation task that entailed monetary rewards. Behavioral results showed that the subjects were more satisfied with the advantageous distribution, regardless of upward or downward comparison. The analysis of event-related potentials revealed that disadvantageous distribution elicited a larger P2 than advantageous distribution, and this effect was not modulated by comparison direction. In contrast, the late positive potential showed an effect of comparison direction independent of subjective evaluation. The data suggest that subjective evaluation acts upon the early stage of reward processing and manifests in the P2 component, whereas social comparison plays a role in the later appraisal process.

In the last two decades, prizes in the sciences have proliferated and, in particular, rich prizes with large honoraria. These developments raise several questions: Why have rich prizes proliferated? Have they greatly changed the reward system of science? What effects will such prizes have on scientists and on science? The proliferation of such prizes derives from marked limitations on the numbers and types of scientists eligible for Nobel prizes and consequent increases in the number of uncrowned laureate-equivalents. These would-be (...) surrogates for Nobel prizes extend the reward system of science in its upper reaches but this change is not fundamental. The spread of rich prizes to new fields provides added incentives to potential winners, which has its own disutilities; it reinforces competitiveness, concern for priority and attendant secrecy, all this amplifying ambivalence toward the reward system in science. There may also be modest positive effects of such new awards in the form of heightened popular esteem for science and interest in it. (shrink)

Creativity has become prevalent in the routine work of knowledge employees in contemporary enterprises. From the perspective of ambidexterity, drawing upon expectancy theory and self-determination theory, the present study highlights the driver behind proactive and responsive creativity. Using two-stage longitudinal data collected from 373 knowledge employee-supervisor dyads in information and manufacturing companies in China, the results show that: performance-contingent rewards have an inverted U-shaped influence on proactive creativity and a U-shaped influence on responsive creativity; performance-contingent rewards have an inverted U-shaped (...) influence on autonomous and controlled motivation; autonomous motivation has a positive influence on proactive creativity, but controlled motivation has a negative influence on responsive creativity; autonomous and controlled motivation play a partly mediating mechanism in the non-linear effects of performance-contingent rewards on proactive and responsive creativity, respectively. Managers should enhance the ambidextrous ability to deal with proactive and responsive creativity and establish an applied and dynamic policy of performance-contingent rewards intensity to drive ambidextrous creativity.

Gender roles are anti-dichotomous and malleable social constructs that should theoretically be constructed independently from biological sex. However, it is unclear whether and how the factor of sex is related to neural mechanisms involved in social constructions of gender roles. Thus, the present study aimed to investigate sex specificity in gender role constructions and the corresponding underlying neural mechanisms. We measured gender role orientation using the Bem Sex-Role Inventory, used a voxel-based global brain connectivity method based on resting-state functional magnetic (...) resonance imaging to characterize the within-network connectivity in the brain reward network, and analyzed how the integration of the reward network is related to gender role scores between sex groups. An omnibus analysis of voxel-wise global brain connectivity values within a two-level linear mixed model revealed that in female participants, femininity scores were positively associated with integration in the posterior orbitofrontal cortex and subcallosal cortex, whereas masculinity scores were positively associated with integration in the frontal pole. By contrast, in male participants, masculinity was negatively correlated with integration in the nucleus accumbens and subcallosal cortex. For the first time, the present study revealed the sex-specific neural mechanisms underlying distinct gender roles, which elucidates the process of gender construction from the perspective of the interaction between reward sensitivity and social reinforcement.
