RESUMEN

INTRODUCTION: Previous research has identified the perception of penalties as one of the most important deterrents to road traffic offenses. This study investigated whether the perceived effectiveness and the perceived strictness of penalties for different traffic offenses are associated with prior punishment experience and evaluation perspective (personal - if participants were being punished themselves, vs. general - for punishing all drivers). METHOD: A convenience sample of 1,374 Lithuanian drivers participated in the survey (56.3% males; aged 18-77 years). Among them, 801 participants had no penalties for traffic offenses, 333 reported monetary fines in the last year, and 240 reported having their drivers license suspended at least once in their driving career. A scale with 10 specific penalties for traffic offenses was developed to measure the perceived effectiveness and strictness of penalties. Half of the participants evaluated the penalties as if they were personally sanctioned for each traffic offense (personal perspective), while the other half assessed the effectiveness and strictness of the penalties for drivers in general. RESULTS: The results indicated that the perceived effectiveness of penalties was related to the evaluation perspective, being higher for changing one's own behavior than for changing behavior in general. However, the perceived effectiveness of penalties was not related to prior punishment experience. Males and drivers who had experienced their license being suspended reported the highest perceived strictness of the penalties, whereas females and drivers with no prior punishment experience perceived penalties as the least strict. PRACTICAL APPLICATIONS: These findings suggest the need for developing new ways of communicating penalties to different groups of drivers. Nevertheless, this research was exploratory in nature and further research is warranted.

RESUMEN

"Pavlovian" or "motivational" biases are the phenomenon that the valence of prospective outcomes modulates action invigoration: the prospect of reward invigorates actions, while the prospect of punishment suppresses actions. Effects of the valence of prospective outcomes are well established, but it remains unclear how the magnitude of outcomes ("stake magnitude") modulates these biases. In this preregistered study (N = 55), we manipulated stake magnitude (high vs. low) in an orthogonalized Motivational Go/NoGo Task. We tested whether higher stakes (a) strengthen biases or (b) elicit cognitive control recruitment, enhancing the suppression of biases in motivationally incongruent conditions. Confirmatory tests showed that high stakes slowed down responding, especially in motivationally incongruent conditions. However, high stakes did not affect whether a response was made or not, and did not change the magnitude of Pavlovian biases. Reinforcement-learning drift-diffusion models (RL-DDMs) fit to the data suggested that response slowing was best captured by stakes prolonging the non-decision time. There was no effect of the stakes on the response threshold (as in typical speed-accuracy trade-offs). In sum, these results suggest that high stakes slow down responses without affecting the expression of Pavlovian biases in behavior. We speculate that this slowing under high stakes might reflect heightened cognitive control, which is however ineffectively used, or reflect positive conditioned suppression, i.e., the interference between goal-directed and consummatory behaviors, a phenomenon previously observed in rodents that might also exist in humans. Pavlovian biases and slowing under high stakes may arise in parallel to each other.

RESUMEN

BACKGROUND: The global prevalence of violence against children is alarmingly high, with millions facing violent discipline and physical punishment. In Mongolia, domestic violence-related criminal offenses have sharply increased, with a 46.92% surge in the first quarter of 2020 compared to 2019. OBJECTIVE: This study aimed to estimate the prevalence of and identify factors associated with physical punishment and/or psychological aggression experienced by children under 5 years old from their caregivers. METHODS: We used data from the nationally representative 2018 MICS6 dataset. To examine the association between independent and dependent variables, we used multilevel Poisson regression because it provides a better estimate and is more interpretable when the prevalence is relatively high. RESULTS: The prevalence of psychological aggression was reported at 32.3% and physical punishment at 31.6%, including severe forms. Nonviolent techniques were common, with 77.5% exclusively using nonviolent discipline. Psychological aggression was more likely to occur in older children (3 and 4 years old) and in households with Buddhist heads. Additionally, 3-year-olds are more likely to experience physical punishment compared to 2-year-olds. CONCLUSION: These findings underscore the need for targeted policy interventions, including age-sensitive parental education programs and religious and cultural sensitivity measures. Comprehensive educational and awareness programs are essential to foster a culture of nonviolence across all educational levels, highlighting the need for context-specific policies to safeguard the well-being of children in Mongolia.

Main finding The study highlights concerning rates of physical punishment and psychological aggression toward children under five in Mongolia.Added Knowledge The study findings contribute novel insights into the intricate relationship between sociocultural factors and disciplinary practices, emphasizing the influence of religious affiliations and maternal education on child-rearing approaches.Global health impact for policy and action Urgent policy interventions are warranted to address violence against children, with an emphasis on culturally sensitive parental education programs and comprehensive awareness campaigns.

RESUMEN

Identifying the origins of moral sensitivities, and their elaboration, within infancy and early childhood is a challenging task, given inherent limitations in infants' behavior. Here, I argue for a multi-pronged, multi-method approach that involves cleaving the moral response at its joints. Specifically, I chart the emergence of infants' moral expectations, evaluations, generalization and enforcement, demonstrating that while many moral sensitivities are present in the second year of life, these sensitivities are closely aligned with, and likely driven by, infants' everyday experience. Moreover, qualitative differences exist between the moral responses that are present in infancy and those of later childhood, particularly in terms of enforcement (i.e., a lack of punishment in infancy). These findings set the stage for addressing outstanding critical questions regarding moral development, that include identifying discrete causal inputs to early moral cognition, identifying whether moral cognition is distinct from social cognition early in life, and explaining gaps that exist between moral cognition and moral behavior in development.

RESUMEN

In this study, we investigated the motivations behind punishing individuals who exploit common resources, a phenomenon crucial for resource preservation. While some researchers suggest punishment stems from concern for the common good, others propose it is driven by anger toward free riders. To probe these motivations, we developed a modified public goods game in which participants had the option to use their own money or the money from the common pool to punish free riders. The analysis included choice behavior, mouse trajectories, and personality traits like anger, empathy, and altruism. According to our results, investments were highest, and punishment was strongest if participants could punish using credits from the common pool, indicating that this is the preferred option to diminish free riding and maintain cooperation in public goods and common good contexts. Also, punishment was highest if the punisher's own investment was high, and the investment of others was low. Concerning traits, highly altruistic individuals tended to invest more and punish less in general but gave harsher punishments when they did choose to use the common pool punitively. Conversely, trait anger and trait empathy were linked to low investment while trait empathy also tended to be related to lower punishment. Taken together, these findings underscore the role of situational factors and personality traits in fostering cooperative behavior and shaping societal norms around costly punishment.

RESUMEN

Third-party intervention is a cornerstone of cooperative societies, yet we know little about how children develop an understanding of this social behavior. The present work generates a cross-cultural and developmental picture of how 6-, 9-, and 12-year-olds (N = 447) across four societies (India, Germany, Uganda, and the United States) reason about third-party intervention. To do so, we measured children's obligation judgments and unstructured descriptions of third-party intervention. Although some cultural differences emerged, 6-year-olds largely considered bystanders as obligated to respond to wrongdoing, regardless of the bystander's social position. In contrast, 9- and 12-year-olds were more likely to exclusively ascribe this social responsibility to people in positions of authority. Despite these age differences, children of all ages generated role-specific descriptions of third-party intervention, with authority figures intervening in distinct ways from peers. For authority figures, children in India and Uganda described third-party intervention as involving corporal punishment or unspecified punishment, whereas children in the United States described such intervention as involving only verbal intervention (i.e., telling someone to stop). For peers, children in all societies described third-party intervention as involving reporting misdeeds to an authority. Collectively, these data show that early conceptualizations of third-party intervention are rooted in shared notions of obligation yet are also subject to cultural and contextual influences.

RESUMEN

BACKGROUND: Adverse childhood experiences (ACEs) may lead to increased problematic media use (PMU). However, whether parental adverse childhood experiences predict offspring PMU, and the mediating roles of psychological distress and harsh discipline, two common mechanisms underlying the intergenerational transmission of parental ACEs, in this relationship have not been examined in Chinese samples. OBJECTIVE: This study examined the serial mediating effects of psychological distress and harsh discipline on the association between parental ACEs and children's PMU. PARTICIPANTS AND SETTING: Participants were 617 three-year-old children and their parents (mean age of 33.24 years, SD = 4.01) from Wuhu, China. METHODS: Parents completed online questionnaires measuring ACEs, psychological distress, and demographic information in September 2022 (Time 1). Parents completed online questionnaires measuring harsh discipline and offspring PMU in September 2023 (Time 2). Macro Process 6 was used to test two serial mediating effects of psychological distress and corporal punishment, as well as psychological distress and psychological aggression. A total of 5000 bootstrap samples were used to estimate the 95 % confidence intervals. A significant effect was indicated by a 95 % confidence interval that did not include zero. RESULTS: The findings suggest that parental ACEs directly and positively predict offspring PMU. Psychological distress and harsh discipline mediate the association between maternal ACEs and offspring PMU parallelly and sequentially. CONCLUSIONS: Our findings highlight the importance of addressing psychological distress and harsh discipline when designing interventions targeting Chinese parents exposed to ACEs and their children.

RESUMEN

In this paper, we study the problem of cost optimisation of individual-based institutional incentives (reward, punishment, and hybrid) for guaranteeing a certain minimal level of cooperative behaviour in a well-mixed, finite population. In this scheme, the individuals in the population interact via cooperation dilemmas (Donation Game or Public Goods Game) in which institutional reward is carried out only if cooperation is not abundant enough (i.e., the number of cooperators is below a threshold 1 ≤ t ≤ N - 1 , where N is the population size); and similarly, institutional punishment is carried out only when defection is too abundant. We study analytically the cases t = 1 for the reward incentive under the small mutation limit assumption and two different initial states, showing that the cost function is always non-decreasing. We derive the neutral drift and strong selection limits when the intensity of selection tends to zero and infinity, respectively. We numerically investigate the problem for other values of t and for population dynamics with arbitrary mutation rates.

RESUMEN

The error-related negativity (ERN) is an event-related potential that is observed after the commission of an error and is hypothesized to index threat sensitivity. The ERN is associated with multiple psychiatric disorders, but it is unclear if similar results are due to higher-order dimensions of psychopathology. When errors are punished, the ERN is further enhanced, which might better isolate threat sensitivity. However, few studies have examined whether psychopathology is associated with punishment enhancement of the ERN. In a clinical sample of 170 adults, the present study examined the association between pathological personality domains and predictable vs. unpredictable punishment-enhanced ERN. Results indicated that the ERN was enhanced when errors were punished compared to not punished. Greater negative emotionality was associated with a greater predictable punishment-enhanced ERN, while greater disinhibition was associated with smaller predictable punishment-enhanced ERN. The study suggests that higher-order pathological personality domains demonstrate discriminate relationships with punishment-enhanced error-related brain activity.

RESUMEN

In cooperative multi-agent reinforcement learning, agents jointly optimize a centralized value function based on the rewards shared by all agents and learn decentralized policies through value function decomposition. Although such a learning framework is considered effective, estimating individual contribution from the rewards, which is essential for learning highly cooperative behaviors, is difficult. In addition, it becomes more challenging when reinforcement and punishment, help in increasing or decreasing the specific behaviors of agents, coexist because the processes of maximizing reinforcement and minimizing punishment can often conflict in practice. This study proposes a novel exploration scheme called multi-agent decomposed reward-based exploration (MuDE), which preferably explores the action spaces associated with positive sub-rewards based on a modified reward decomposition scheme, thus effectively exploring action spaces not reachable by existing exploration schemes. We evaluate MuDE with a challenging set of StarCraft II micromanagement and modified predator-prey tasks extended to include reinforcement and punishment. The results show that MuDE accurately estimates sub-rewards and outperforms state-of-the-art approaches in both convergence speed and win rates.

RESUMEN

Theories of justice suggest that it serves two main purposes: punishment and restoration. Although punishment emerges early and has been well-documented, little is known about the contexts in which young children engage in restorative practices like compensation for victims. The current study investigated whether children's engagement in compensation and punishment (which often involve a redistribution of resources) was sensitive to characteristics of the perpetrator and victim known to shape distributive justice decisions (decisions about how resources should be distributed), such as social dominance, resource inequality, and moral character. A total of 54 children aged 3 to 7 years completed a series of moral judgment experiments. Each experiment featured interactions between a perpetrator and a victim, ending with the perpetrator stealing the victim's toy. In Experiment 1 (N = 44), social dominance did not affect punishment or compensation overall, but older children compensated the dominant victim (but not the subordinate victim) less than younger children. In Experiment 2 (N = 42), children compensated the poor victim more than the rich victim, but they did not punish the rich perpetrator more than the poor perpetrator. In Experiment 3 (N = 45), children compensated the victim with a good moral character more than the victim with a bad moral character, and the victim's moral character did not influence punishment. Altogether, these findings offer new insights into how children resort to compensation for victims as a complement to, rather than an alternative to, punishment.

RESUMEN

BACKGROUND: Although limited, there is some evidence that certain physical punishments may vary by household religion. OBJECTIVE: This study aimed to determine whether parent disciplinary behavior varies by religious affiliation in two countries which have large, diverse religious groups. PARTICIPANTS AND SETTING: Data from Multiple Indicator Cluster Surveys for Suriname (2018) and Guyana (2019-20), which contain nationally representative household samples, were used. The study was restricted to the three most prevalent religious groups: Christians, Hindus, and Muslims. METHODS: Adult responses to a standardized survey that included questions about use of disciplinary behaviors in the household towards children (aged 1-14 years) were examined in relation to religious affiliation of the head-of-household and multiple covariates. RESULTS: Of the 3518 Suriname households, 62.4 %, 23.3 % and 14.3 % were Christians, Hindus, and Muslims, respectively. Compared to Christians, children in both Hindu and Muslim households had significantly lower odds of being hit with an object in adjusted logistic regression models. However, only Hindus had lower odds of being spanked and Muslims lower odds of exposure to a combined physical and non-physical practice, compared to Christians. Of the 2535 Guyana households, 69.5 %, 23.5 % and 7.0 % were Christians, Hindus, and Muslims, respectively. Children in Hindu, but not Muslim households, had significantly lower odds of being spanked, hit with an object, and exposed to a combine practice in adjusted models compared to Christians. CONCLUSIONS: Partial support was found for a potential influence of religion on some disciplinary behaviors. Further investigation is warranted to identify possible conditions and mechanisms.

RESUMEN

This study examines how in-group bias affects altruistic sharing and second-party punishment in preschoolers and the role of theory of mind (ToM) in in-group bias. Preschoolers aged 4 to 7 years (N = 309; 160 girls) were asked to share resources with an in-group member and an out-group member (Dictator Game) and to reject or accept an unequal allocation proposed by an in-group member and an out-group member (Ultimatum Game). The results showed that preschoolers shared more resources with, and tolerated more unfair behaviors from, in-group members. ToM influenced the in-group bias in both altruistic sharing and second-party punishment. Notably, children's degree of in-group favoritism in altruistic sharing was positively related to the second-party punishment children imposed on out-group members. However, this pattern was found only among children who had acquired first-order ToM. This study reveals the developmental patterns of preschoolers' in-group bias in altruistic sharing and second-party punishment and the effects of ToM on in-group bias.

RESUMEN

OBJECTIVE: This study aimed to explore young people's perceptions and experiences on access to voluntary termination of pregnancy (VTP) in northern Mozambique. METHODS: A qualitative study of twelve focus group discussions was conducted from June to September 2021 in Nampula province, northern Mozambique. A total of 94 purposively selected 15-24-year-old males and females participated in the study. Data was inductively coded and reflexive thematic analysis inspired by Braun and Clarke was applied. Socio-Ecological theory was used to frame the discussion. RESULTS: Despite VTP being decriminalized and by law to be provided free of charge, unsafe abortion remains a common choice among young people towards unintended pregnancy. Barriers to help-seeking access to safe VTP include: 1) fear, 2) sociocultural gendered norms and power dynamics, 3) lack of VTP service provision at nearest health facilities, and 4) unaffordable services where available. Fear associated with early forced marriage, a parental corrective action towards premarital pregnancy coupled with lack of male financial autonomy to afford illicit charges, remain the most important factors preventing young people seeking for help at family and safe VTP services at facility level. CONCLUSIONS: Amidst multiple barriers in accessing health services, unsafe abortion is viewed by young people as a better option than facing a lifetime punishment of early forced marriage, a common parental corrective action towards premarital pregnancy.

RESUMEN

Exposure to exclusionary discipline has been tied to several deleterious outcomes in adulthood, including contact with the criminal legal system. While this work provides interesting insight into the long-term consequences tied to this form of school punishment, few have attempted to consider whether and how, exclusionary discipline practices, in particular, school suspension and expulsion shape mental health patterning over the life course. Using panel data from the National Longitudinal Study of Adolescent to Adult Health, we contribute to this body of literature by examining whether exposure to school suspension or expulsion shapes depressive symptom trajectories from adolescence to adulthood. Results from our mixed-effects linear growth curve models demonstrate both forms of exclusionary discipline play a significant role in depressive symptom trajectories. We find suspended and expelled youth exhibit significantly higher depressive symptoms in adolescence when compared to their counterparts with no history of suspension or expulsion. Results also show age variation in depressive symptom trajectories by history of exposure to exclusionary discipline. Specifically, results show the depressive symptoms gap between disciplined and non-disciplined youth slightly dissipates as youth age into early adulthood, but as individuals begin to transition out of this stage of the life course, the gap in depressive symptoms widens substantially. Results carry implications for how punitive disciplinary practices in schools shape mental health from adolescence to adulthood.

RESUMEN

OBJECTIVES: There has been substantial and growing interest in the therapeutic utility of drugs acting at serotonin 2A subtype (5-HT 2A ) receptors, increasing the need for characterization of potential beneficial and adverse effects of such compounds. Although numerous studies have evaluated the possible rewarding and reinforcing effects of 5-HT 2A receptor agonists, there have been relatively few studies on potential aversive effects. METHODS: The current study investigated punishing effects of 2,5-dimethoxy-4-methylamphetamine (DOM) in four rhesus monkeys responding under a choice procedure in which responding on one lever delivered a sucrose pellet alone and responding on the other lever delivered a sucrose pellet plus an intravenous infusion of a range of doses of fentanyl (0.1-3.2 µg/kg/infusion), histamine (3.2-100 µg/kg/infusion), or DOM (3.2-100 µg/kg/infusion). RESULTS: When fentanyl was available, responding for a pellet plus an infusion increased dose dependently in all subjects, indicating a positive reinforcing effect of fentanyl. When histamine was available, responding for a pellet plus an infusion decreased in three of four subjects, indicating a punishing effect of histamine. Whether available before or after histamine, DOM did not systematically alter choice across the range of doses tested. CONCLUSION: These results suggest that the 5-HT 2A receptor agonist DOM has neither positive reinforcing nor punishing effects under a choice procedure that is sensitive to both processes.

RESUMEN

The study employed event-related potential (ERP), time-frequency analysis, and functional connectivity to comprehensively explore the influence of male's relative height on third-party punishment (TPP) and its underlying neural mechanism. The results found that punishment rate and transfer amount are significantly greater when the height of the third-party is lower than that of the recipient, suggesting that male's height disadvantage promotes TPP. Neural results found that the height disadvantage induced a smaller N1. The height disadvantage also evoked greater P300 amplitude, more theta power, and more alpha power. Furthermore, a significantly stronger wPLI between the rTPJ and the posterior parietal and a significantly stronger wPLI between the DLPFC and the posterior parietal were observed when third-party was at the height disadvantage. These results imply that the height disadvantage causes negative emotions and affects the fairness consideration in the early processing stage; the third-party evaluates the blame of violators and makes an appropriate punishment decision later. Our findings indicate that anger and reputation concern caused by height disadvantage promote TPP. The current study holds significance as it underscores the psychological importance of height in males, broadens the perspective on factors influencing TPP, validates the promoting effect of personal disadvantages on prosocial behavior, enriches our understanding of indirect reciprocity theory, and extends the application of the evolution theory of Napoleon complex.

RESUMEN

Altruistic punishment is key to establishing cooperation and maintaining social order, yet its developmental trends across cultures remain unclear. Using computational reinforcement learning models, we provided the first evidence of how social feedback dynamically influences group-biased altruistic punishment across cultures and the lifespan. Study 1 (n = 371) found that Chinese participants exhibited higher learning rates than Americans when socially incentivized to punish unfair allocations. Additionally, Chinese adults showed slower learning and less exploration when punishing ingroups than outgroups, a pattern absent in American counterparts, potentially reflecting a tendency towards ingroup favoritism that may contribute to reinforcing collectivist values. Study 2 (n = 430, aged 12-52) further showed that such ingroup favoritism develops with age. Chinese participants' learning rates for ingroup punishment decreased from adolescence into adulthood, while outgroup rates stayed constant, implying a process of cultural learning. Our findings highlight cultural and age-related variations in altruistic punishment learning, with implications for social reinforcement learning and culturally sensitive educational practices promoting fairness and altruism.

RESUMEN

In an animal model of compulsive drug use, a subset of rats continues to self-administer cocaine despite footshock consequences and is considered punishment resistant. We recently found that punishment resistance is associated with habits that persist under conditions that typically encourage a transition to goal-directed control. Given that random ratio (RR) and random interval (RI) schedules of reinforcement influence whether responding is goal-directed or habitual, we investigated the influence of these schedules on punishment resistance for cocaine or food. Male and female Sprague Dawley rats were trained to self-administer either intravenous cocaine or food pellets on a seeking-taking chained schedule of reinforcement, with the seeking lever requiring completion of either an RR20 or RI60 schedule. Rats were then given four days of punishment testing with footshock administered at the completion of seeking on a random one-third of trials. For cocaine-trained rats, the RI60 schedule led to greater punishment resistance (i.e., more trials completed) than the RR20 schedule in males and females. For food-trained rats, the RI60 schedule led to greater punishment resistance (i.e., higher reward rates) than the RR20 schedule in female rats, although male rats showed punishment resistance on both RR20 and RI60 schedules. For both cocaine and food, we found that seeking responses were suppressed to a greater degree than reward rate with the RI60 schedule, whereas response rate and reward rate were equally suppressed with the RR20 schedule. This dissociation between punishment effects on reward rate and response rate with the RI60 schedule can be explained by the nonlinear relation between these variables on RI schedules, but it does not account for the enhanced resistance to punishment. Overall, the results show greater punishment resistance with the RI60 schedule as compared to the RR20 schedule, indicating that schedules of reinforcement are an influencing factor on resistance to negative consequences.
