ABSTRACT

In contemporary society, the effective utilization of public resources remains a subject of significant concern. A common issue arises from defectors seeking to obtain an excessive share of these resources for personal gain, potentially leading to resource depletion. To mitigate this tragedy and ensure sustainable development of resources, implementing mechanisms to either reward those who adhere to distribution rules or penalize those who do not, appears advantageous. We introduce two models: a tax-reward model and a tax-punishment model, to address this issue. Our analysis reveals that in the tax-reward model, the evolutionary trajectory of the system is influenced not only by the tax revenue collected but also by the natural growth rate of the resources. Conversely, the tax-punishment model exhibits distinct characteristics when compared with the tax-reward model, notably the potential for bistability. In such scenarios, the selection of initial conditions is critical, as it can determine the system's path. Furthermore, our study identifies instances where the system lacks stable points, exemplified by a limit cycle phenomenon, underscoring the complexity and dynamism inherent in managing public resources using these models.

ABSTRACT

This Note explores the intricate relationship between emerging adulthood, defined as the transitional phase between youth and adulthood (ages 18-25), and the legal implications of capital punishment. Contrary to a fixed age determining adulthood, research highlights the prolonged nature of the maturation process, especially for individuals impacted by Adverse Childhood Experiences (ACEs). The Note challenges the current legal framework that deems individuals aged 18 to 25 who experienced ACEs as eligible for capital punishment, highlighting the cognitive impact of ACEs on developmental trajectories. Examining cases like Dzhokhar Tsarnaev and Billy Joe Wardlow, this Note argues that courts often bypass mitigating evidence related to ACEs, thereby perpetuating judicial errors. The mismatched burdens of proof for aggravating and mitigating factors further compound the problem, contributing to a flawed system that disproportionately affects emerging adults. In response to these issues, some states are reevaluating their approach to emerging adult justice, considering initiatives such as "raise the age" campaigns and specialized courts. The Note promotes an approach that aligns with cognitive age appropriateness, tailoring interventions to encompass restorative justice, rehabilitative measures, and a comprehensive legal framework to address the distinct needs of the emerging adult population. Recognizing the potential for cognitive development and rehabilitation during this transitional phase, this Note contends that alternative methods can provide opportunities for ACE-impacted individuals to age out of criminal behaviors, potentially altering life trajectories and mitigating the imposition of capital punishment.

ABSTRACT

Following a randomized controlled trial that showed effectiveness of an equity-centered positive behavioral interventions and supports (PBIS) professional development intervention on student discipline in elementary schools, we studied the extent to which the intervention had differential effects on individual teachers' use of exclusionary discipline. Using the sample of teachers from the randomized controlled trial (n = 348), we assessed whether (a) changes in teacher use of office discipline referrals over the course of 2 school years and (b) intervention acceptability were moderated by teacher demographic characteristics (e.g., race/ethnicity, experience) or teacher attitudes (e.g., awareness of biases and commitment to equity). Results from multilevel models using two discipline outcomes (i.e., office discipline referrals issued to Black students and equity in office discipline referrals) did not show significant moderation effects for any demographic or attitude variables. Results of intervention acceptability found that teachers with pre-existing commitments to bias reduction found the intervention more acceptable, although means were consistently high across the sample. Findings indicate that the intervention was similarly effective on teacher discipline practices, regardless of teacher demographics or pre-existing attitudes, lending more support to the intervention's promise.

ABSTRACT

Teacher-student relationships are beneficial for students and especially important in the middle school context. Suspensions are critical to reduce as it can be detrimental to the educational trajectory of students, particularly for marginalized students in underfunded schools. This study looked at the relations between teacher-student relationships and suspensions across the academic year in a sample of students (N = 541) and teachers (N = 51) in two urban school districts in the Midwest. A brief measure of teachers' perceptions of relationships with students completed in the fall of the academic year predicted the odds of receiving in-school suspension (ISS; odds ratio [OR] = 0.65) and out-of-school suspension (OSS; OR = 0.72) by the end of the school year. Student reports of the relationships were also associated with ISS (OR = 0.94), but not OSS. On average, teachers' report on the scale improved over the course of the school year (d = 0.11); however, student report of the relationships worsened (d = 0.30). The difference in the student report of the relationships from fall to spring was also associated with the odds of receiving ISS and OSS (ORs = 0.94). These findings suggest that student and teacher perceptions together are associated with harsh discipline practices that can negatively impact students' developmental trajectories. Relationships can change but direct action is necessary to develop, maintain, and repair relationships during the academic year.

ABSTRACT

Parvalbumin (PV)-expressing GABAergic neurons of the basal forebrain (BFPVNs) were proposed to serve as a rapid and transient arousal system, yet their exact role in awake behaviors remains unclear. We performed bulk calcium measurements and electrophysiology with optogenetic tagging from the horizontal limb of the diagonal band of Broca (HDB) while male mice were performing an associative learning task. BFPVNs responded with a distinctive, phasic activation to punishment, but showed slower and delayed responses to reward and outcome-predicting stimuli. Optogenetic inhibition during punishment impaired the formation of cue-outcome associations, suggesting a causal role of BFPVNs in associative learning. BFPVNs received strong inputs from the hypothalamus, the septal complex and the median raphe region, while they synapsed on diverse cell types in key limbic structures, where they broadcasted information about aversive stimuli. We propose that the arousing effect of BFPVNs is recruited by aversive stimuli to serve crucial associative learning functions.

ABSTRACT

People tend to intervene in others' injustices by either punishing the transgressor or helping the victim. Injustice events often occur under stressful circumstances. However, how acute stress affects a third party's intervention in injustice events remains open. Here, we show a stress-induced shift in third parties' willingness to engage in help instead of punishment by acting on emotional salience and central-executive and theory-of-mind networks. Acute stress decreased the third party's willingness to punish the violator and the severity of the punishment and increased their willingness to help the victim. Computational modeling revealed a shift in preference of justice recovery from punishment the offender toward help the victim under stress. This finding is consistent with the increased dorsolateral prefrontal engagement observed with higher amygdala activity and greater connectivity with the ventromedial prefrontal cortex in the stress group. A brain connectivity theory-of-mind network predicted stress-induced justice recovery in punishment. Our findings suggest a neurocomputational mechanism of how acute stress reshapes third parties' decisions by reallocating neural resources in emotional, executive, and mentalizing networks to inhibit punishment bias and decrease punishment severity.

ABSTRACT

BACKGROUND/OBJECTIVES: The present study investigated the extent to which fathers and mothers at high-risk and low-risk for child physical abuse (CPA) differed in their use of harsh discipline and punishment when presented ambiguous child situations (situations where differences in positive and negative valences are close to zero). PARTICIPANTS/METHODS: High-risk for CPA parents (N = 74: fathers, n = 41; mothers, n = 33) and low-risk parents (N = 178: fathers, n = 91; mothers, n = 87) were asked to indicate their likelihood of using harsh verbal discipline (HVD), harsh physical discipline (HPD), and punishment (i.e., retributive harm separate from HVD and HPD) after viewing each of eighteen ambiguous child situations. RESULTS: As expected, high-risk, compared to low-risk, for CPA parents were significantly (ps < 0.001) more likely to use HVD (d = 0.546), HPD (d = 0.595), and punishment (d = 0.564). Overall, fathers, relative to mothers, were significantly more likely to use HVD (d = 0.261) and HPD (d = 0.238). For punishment, however, there was no significant parental role (father, mother) difference (d = 0.136). CONCLUSIONS: Since in everyday living situations many child behaviors are ambiguous, the findings that parents, especially high-risk for CPA parents, use harsh discipline and punishment when encountering ambiguous child situations suggest that non-contingent harsh child-related parental behaviors may be frequent in the lives of some children. The findings that parents may use non-contingent discipline and punishment suggest the need to explore whether, when these parenting behaviors occur, they increase the likelihood of negative child outcomes.

ABSTRACT

There is a huge funding gap in the abandoned mines ecological restoration in China. It is of great research value to explore how PPP model can better introduce social capital into the low-profit ecological restoration of abandoned mines. Based on the innovation perspective of the central government's reward and punishment system, this paper constructs an evolutionary game model of "local government-social capital", analyzes the interaction and behavior mechanism of core stakeholders in the operation process of abandoned mines ecological restoration PPP mode, and discusses the influence of evolutionary equilibrium strategy and parameters change on evolutionary strategy under different scenarios by Matlab simulation. The research shows that the abandoned mines ecological restoration needs the support of the central government. When the local government lightly punishes the low-quality service of social capital, the central government needs to pay higher costs to promote all parties to actively participate in the operation and supervision of the PPP project. The revenue and cost of government supervision, the operating subsidy for social capital and the cost saved by social capital in providing bad service are the key factors affecting the evolution of the game between government and social capital. Punishment can effectively spur social capital to keep the contract and operate in the project, but the punishment effect will be ineffective without government supervision. Finally, some suggestions are put forward, such as establishing a long-term supervision mechanism and a reasonable income mechanism for PPP projects, increasing penalties for violations, attracting third parties to reduce supervision costs and strengthening communication between the two parties, so as to make the project take into account the economic performance of social capital and the social welfare of government departments, and achieve dual Pareto improvement.

ABSTRACT

ABSTRACTBackground: Maternal adverse childhood experiences (ACEs) may lead to increased behavioural problems in children. However, the mediating roles of psychological distress and corporal punishment, two common mechanisms underlying the intergenerational transmission of maternal ACEs, in these relations have not been examined in Chinese samples. Multigenerational homes (MGH) are the dominate living arrangement in China; however, limited research focuses on the effects of MGHs on the intergenerational transmission of maternal ACEs.Objective: This study explored the parallel mediating effects of corporal punishment and psychological distress on the association between maternal ACEs and children's behaviour and whether MGHs can strengthen or weaken the relationship between maternal ACEs and corporal punishment or psychological distress.Participants and setting: Participants were 643 three-year-old children and their mothers (mean age of 32.85 years, SD = 3.79) from Wuhu, China.Methods: Mothers completed online questionnaires measuring ACEs, psychological distress, corporal punishment, their family structure, and children's behavioural problems. This study used a moderated mediation model.Results: The findings suggest that psychological distress and corporal punishment mediate the association between maternal ACEs and children's behavioural problems. The mediating role of corporal punishment was found depend on whether mothers and their children reside in MGHs. MGHs were not found to have a moderating role in the indirect relationship between maternal ACEs and children's behaviour problems via psychological distress.Conclusion: Our findings highlight the importance of addressing psychological distress and corporal punishment when designing interventions targeted Chinese mothers exposed to ACEs and their children, especially those living in MGHs.


Psychological distress and corporal punishment have parallel mediating roles in the associations between maternal adverse childhood experiences and offspring behavioural problems.Mothers with more adverse childhood experiences and in multigenerational homes were more likely to use corporal punishment.Multigenerational homes did not moderate the indirect relationship via psychological distress.

ABSTRACT

Recent studies suggest that depression and anxiety are associated with unique aspects of EEG responses to reward and punishment, respectively; also, abnormal responses to punishment in depressed individuals are related to anxiety, the symptoms of which are comorbid with depression. In a non-clinical sample, we aimed to investigate the relationships between reward processing and anxiety, between punishment processing and anxiety, between reward processing and depression, and between punishment processing and depression. Towards this aim, we separated feedback-related brain activity into delta and theta bands to isolate activity that indexes functionally distinct processes. Based on the delta/theta frequency and feedback valence, we then used machine learning (ML) to classify individuals with high severity of depressive symptoms and individuals with high severity of anxiety symptoms versus controls. The significant difference between the depression and control groups was driven mainly by delta activity; there were no differences between reward- and punishment-theta activities. The high severity of anxiety symptoms was marginally more strongly associated with the punishment- than the reward-theta feedback processing. The findings provide new insights into the differences in the impacts of anxiety and depression on reward and punishment processing; our study shows the utility of ML in testing brain-behavior hypotheses and emphasizes the joint effect of theta-RewP/FRN and delta frequency on feedback-related brain activity.

ABSTRACT

Higher sensitivity to reward (SR) and weaker sensitivity to punishment (SP) construct the fundamental craving characteristics of methamphetamine abuse. However, few studies have appraised relationships between SR/SP (SR or SP) and cortical morphological alterations in methamphetamine abusers and whether hereditary factors take effects on SR/SP is unclear. Based on surface-based morphometric analysis, cortical discrepancy was investigated between 38 methamphetamine abusers and 37 healthy controls. Within methamphetamine abusers, correlation profiling was performed to discover associations among aberrant neuroimaging substrates, SR, SP, and craving. According to nine single nucleotide polymorphism sites of dopamine-related genes, we conducted univariate general linear model to find different effects of genotypes on cortical alterations and SR/SP/craving (SR, SP, or craving). Ultimately, mediation analyses were conducted among single nucleotide polymorphism sites, SR/SP/craving, and cortical morphological alterations to discover their association pathways. Compared to healthy controls, thinner cortices in inferior temporal gyrus, lateral orbitofrontal cortex, medial orbitofrontal cortex, inferior parietal lobule, and lateral occipital cortex in the left hemisphere were found in methamphetamine abusers (P < 0.05, family-wise error corrected). Cortical thickness in the inferior temporal gyrus was negatively correlated with SR scores. We found that rs1800497 A-containing genotypes had lower cortical thickness in the left inferior parietal lobule than the GG genotype. The rs5751876 had effects on SR scores. This study would provide convincing biomarkers for SR in methamphetamine abusers and offer potential genetic targets for personalizing relapse prevention.

ABSTRACT

Punishment of moral norm violators is instrumental for human cooperation. Yet, social and affective neuroscience research has primarily focused on second- and third-party norm enforcement, neglecting the neural architecture underlying observed (vicarious) punishment of moral wrongdoers. We used naturalistic television drama as a sampling space for observing outcomes of morally-relevant behaviors to assess how individuals cognitively process dynamically evolving moral actions and their consequences. Drawing on Affective Disposition Theory, we derived hypotheses linking character morality with viewers' neural processing of characters' rewards and punishments. We used functional magnetic resonance imaging (fMRI) to examine neural responses of 28 female participants while free-viewing 15 short story summary video clips of episodes from a popular US television soap opera. Each summary included a complete narrative structure, fully crossing main character behaviors (moral/immoral) and the consequences (reward/punishment) characters faced for their actions. Narrative engagement was examined via intersubject correlation and representational similarity analysis. Highest cortical synchronization in 9 specifically selected regions previously implicated in processing moral information was observed when characters who act immorally are punished for their actions with participants' empathy as an important moderator. The results advance our understanding of the moral brain and the role of normative considerations and character outcomes in viewers' engagement with popular narratives.

ABSTRACT

In Public Goods Games (PGG), the temptation to free-ride on others' contributions poses a significant threat to the sustainability of cooperative societies. Therefore, societies strive to mitigate this through incentive systems, employing rewards and punishments to foster cooperative behavior. Thus, peer punishment, in which cooperators sanction defectors, as well as pool punishment, where a centralized punishment institution executes the punishment, is deeply analyzed in previous works. Although the literature indicates that these methods may enhance cooperation on social dilemmas under particular contexts, there are still open questions, for instance, the structural connection between graduated punishment and the monitoring of public goods games. Our investigation proposes a compulsory PGG framework under Panoptical surveillance. Inspired by Foucault's theories on disciplinary mechanisms and biopower, we present a novel mathematical model that scrutinizes the balance between the severity and scope of punishment to catalyze cooperative behavior. By integrating perspectives from evolutionary game theory and Foucault's theories of power and discipline, this research uncovers the theoretical foundations of mathematical frameworks involved in punishment and discipline structures. We show that well-calibrated punishment and discipline schemes, leveraging the panoptical effect for universal oversight, can effectively mitigate the free-rider dilemma, fostering enhanced cooperation. This interdisciplinary approach not only elucidates the dynamics of cooperation in societal constructs but also underscores the importance of integrating diverse methodologies to address the complexities of fostering cooperative evolution.

ABSTRACT

In middle childhood, children's sense of fairness further develops, they are willing to pay a cost to maintain equality. Win-win and lose-lose are two forms of equality. Win-win equality refers to both parties maximizing benefits, while lose-lose equality means both parties incurring the maximum loss. Win-win equality allows third party upholding fairness to gain more reputational benefits without the violator being punished, embodying the principle of "benefiting oneself without harming others". On the other hand, lose-lose equality is a more deterrent form of fairness with the violator getting punished, and the third-party might experience a situation of "effort without appreciation." However, the specific form of equality which school-aged children prefer still requires further exploration. Therefore, adopting the dictator game paradigm of third-party punishment, we design two experiments to investigate the fairness preference of first to fourth-grade children when acting as a third party and to clarify patterns of age-related changes. Study 1 (N = 111) explored children's preferred form of fairness under advantageous inequity conditions. Study 2 (N = 122) further examined children's fairness preferences in disadvantageous inequity situations. The findings suggest that when confronted with inequitable distributions, whether rooted in disadvantageous or advantageous inequity, children display a notable tendency to utilize third-party punishment to achieve an equal allocation. Meanwhile, this tendency strengthens as they progress in grade levels. Notably, children consistently manifest a preference for win-win equality, highlighting their inclination towards mutually beneficial outcomes.

ABSTRACT

Countless policies are crafted with the intention of punishing all who do wrong or rewarding only those who do right. However, this requires accommodating certain mistakes: some who do not deserve to be punished might be, and some who deserve to be rewarded might not be. Six preregistered experiments (N = 3,484 U.S. adults) reveal that people are more willing to accept this trade-off in principle, before errors occur, than in practice, after errors occur. The result is an asymmetry such that for punishments, people believe it is more important to prevent false negatives (e.g., criminals escaping justice) than to fix them, and more important to fix false positives (e.g., wrongful convictions) than to prevent them. For rewards, people believe it is more important to prevent false positives (e.g., welfare fraud) than to fix them and more important to fix false negatives (e.g., improperly denied benefits) than to prevent them.

ABSTRACT

Exposure to highly palatable food is believed to induce behavioral and neurobiological changes that may produce addiction-like behavior and increase the risks of obesity and overweight. Studies in rodents have led to conflicting results suggesting that several factors such as sex and age of exposure contribute to the development of maladaptive behaviors towards food. In addition, it is not clear whether effects of exposure to highly palatable diets (HPD) persist after their discontinuation, which would indicate long-term risks to develop addiction-like behavior. In this study, we investigated the persistent effects of an intermittent 8-week exposure to HPD in male and female rats as a function of age of exposure (adult and adolescent). We found that intermittent exposure to HPD did not alter body weight, but it affected consumption of standard food during the time of exposure in all groups. In addition, in adults, HPD produced a decrease in the initial baseline responding in FR1 schedules, an effect that persisted for 4 weeks in males but not in female rats. However, we found that exposure to HPD did not affect resistance to punishment measured by progressive shock strength break points or motivation for food as measured by progressive-ratio break points regardless of sex or age of exposure. Altogether, these results do not provide support for the hypothesis that intermittent exposure to HPD produce persistent increases in the vulnerability to develop addiction-like behaviors towards palatable food.

ABSTRACT

Learning to stop responding is a fundamental process in instrumental learning. Animals may learn to stop responding under a variety of conditions that include punishment-where the response earns an aversive stimulus in addition to a reinforcer-and extinction-where a reinforced response now earns nothing at all. Recent research suggests that punishment and extinction may be related manifestations of a common retroactive interference process. In both paradigms, animals learn to stop performing a specific response in a specific context, suggesting direct inhibition of the response by the context. This process may depend on the infralimbic cortex (IL), which has been implicated in a variety of interference-based learning paradigms including extinction and habit learning. Despite the behavioral parallels between extinction and punishment, a corresponding role for IL in punishment has not been identified. Here we report that, in a simple arrangement where either punishment or extinction was conducted in a context that differed from the context in which the behavior was first acquired, IL inactivation reduced response suppression in the inhibitory context, but not responding when it "renewed" in the original context. In a more complex arrangement in which two responses were first trained in different contexts and then extinguished or punished in the opposite one, IL inactivation had no effect. The results advance our understanding of the effects of IL in retroactive interference and the behavioral mechanisms that can produce suppression of a response.

ABSTRACT

Processing and learning from affective cues to guide goal-directed behavior may be particularly important during adolescence; yet the factors that promote and/or disrupt the ability to integrate value in order to guide decision making across development remain unclear. The present study (N = 1046) assessed individual difference factors (self-reported punishment and reward sensitivity) related to whether previously-rewarded and previously-punished cues differentially impact goal-directed behavior (response inhibition) in a large developmental sample. Participants were between the ages of 8-21 years (Mage = 14.29, SD = 3.97, 50.38% female). Previously-rewarded cues improved response inhibition among participants age 14 and older. Further, punishment sensitivity predicted overall improved response inhibition among participants aged 10 to 18. The results highlight two main factors that are associated with improvements in the ability to integrate value to guide goal-directed behaviour - cues in the environment (e.g., reward-laden cues) and individual differences in punishment sensitivity. These findings have implications for both educational and social policies aimed at characterizing the ways in which youth integrate value to guide decision making.
