Physical and other types of punishment remain common in Bangladesh, despite overwhelming evidence of their harm and worldwide efforts to decrease their use. One of the strategic priorities of Save the Children in Bangladesh's Child Protection Program is to protect children from physical and humiliating punishment in homes, schools, and other settings. Save the Children in Bangladesh selected the Positive Discipline in Everyday Parenting (PDEP) Program to provide parents with alternatives to physical punishment that comply with human rights standards while strengthening relationships and understanding of child development. High-risk communities where children are particularly vulnerable were selected for this project. The PDEP program was delivered to 857 parents living in lower socioeconomic areas of Bangladesh, including ethnic minority groups, and parents living in urban slums of Dhaka and rural brothel areas. Due to the low levels of education of the participants (almost two-thirds of participants had not completed elementary school), simplified pre and posttests were utilized. Following program completion, parents' approval of both physical punishment and punishment in general declined; they were less likely to view typical parent-child conflicts as intentional misbehavior and were less reactive to frustration. In addition, parents indicated an increased understanding of the positive discipline and more confidence in their parenting skills. Before taking PDEP, 64% of the parents often felt like they just did not know what to do as a parent, compared to 34% following program completion. PDEP demonstrated the potential to decrease the use of physical and humiliating punishments by parents living in high-risk communities in Bangladesh.

Modular Reinforcement Learning decomposes a monolithic task into several tasks with sub-goals and learns each one in parallel to solve the original problem. Such learning patterns can be traced in the brains of animals. Recent evidence in neuroscience shows that animals utilize separate systems for processing rewards and punishments, illuminating a different perspective for modularizing Reinforcement Learning tasks. MaxPain and its deep variant, Deep MaxPain, showed the advances of such dichotomy-based decomposing architecture over conventional Q-learning in terms of safety and learning efficiency. These two methods differ in policy derivation. MaxPain linearly unified the reward and punishment value functions and generated a joint policy based on unified values; Deep MaxPain tackled scaling problems in high-dimensional cases by linearly forming a joint policy from two sub-policies obtained from their value functions. However, the mixing weights in both methods were determined manually, causing inadequate use of the learned modules. In this work, we discuss the signal scaling of reward and punishment related to discounting factor γ, and propose a weak constraint for signaling design. To further exploit the learning models, we propose a state-value dependent weighting scheme that automatically tunes the mixing weights: hard-max and softmax based on a case analysis of Boltzmann distribution. We focus on maze-solving navigation tasks and investigate how two metrics (pain-avoiding and goal-reaching) influence each other's behaviors during learning. We propose a sensor fusion network structure that utilizes lidar and images captured by a monocular camera instead of lidar-only and image-only sensing. Our results, both in the simulation of three types of mazes with different complexities and a real robot experiment of an L-maze on Turtlebot3 Waffle Pi, showed the improvements of our methods.

Reward and punishment processing are subject to substantial developmental changes during youth. However, little is known about the neurophysiological correlates that are associated with these developmental changes, particularly with regard to both anticipatory and outcome processing stages. Thus, the aim of this study was to address this research gap in a sample of typically developing children and adolescents. Fifty-four children and adolescents (8-18 years) performed a Monetary Incentive Delay Task comprising a monetary reward and punishment condition. Using event-related brain potential recordings, the cue-P3 and the stimulus-preceding negativity (SPN) were analyzed during the anticipation phase, while the Reward Positivity and the feedback-P3 were analyzed during the outcome phase. When anticipating monetary loss or no gain, SPN amplitude in the right hemisphere decreased with age. Moreover, exploratory analyses revealed a decrease in feedback-P3 amplitudes in response to monetary loss with increasing age. No other group differences were observed. Age-related changes in the SPN and fP3 component suggest that sensitivity to negative outcomes decreases from childhood to late adolescence, supporting the notion that adolescence is associated with reduced harm-avoidance. Longitudinal research including young adults is needed to substantiate our findings and its clinical implications regarding disturbed developmental trajectories in psychiatric populations.

Child physical punishment is harmful to children and, as such, is being prohibited by a growing number of countries, including Wales. Parents' own childhood histories may affect their risks of using child physical punishment. We conducted a national cross-sectional survey of Welsh adults and measured relationships between the number of adverse childhood experiences (ACEs) parents (n = 720 with children aged < 18) had suffered during childhood and their use of physical punishment towards children. Overall, 28.2% of parents reported having ever physically punished a child, and 5.8% reported having done so recently (in the last year). Child physical punishment use increased with the number of ACEs parents reported. Parents with 4+ ACEs were almost three times more likely to have ever physically punished a child and eleven times more likely to have done so recently (vs. those with 0 ACEs). The majority (88.1%) of parents that reported recent child physical punishment had a personal history of ACEs, while over half reported recently having been hit themselves by a child. Child physical punishment is strongly associated with parents' own ACE exposure and can occur within the context of broader conflict. Prohibiting physical punishment can protect children and, with appropriate family support, may help break intergenerational cycles of violence.

Randomized Controlled Trial
Psychosocial stress modulates social cognition and behavior in humans. One potentially mediating factor is cortisol as part of the human endocrine stress response. With a double-blind, placebo-controlled between-subject study design, we tested possible dose-dependent effects of hydrocortisone (0 mg, 5 mg and 20 mg) in 85 healthy males. During a socio-economic decision-making task we measured trust, trustworthiness, sharing, punishment, and non-social risk behavior. Social value orientation (SVO) was also assessed. We observed significantly lower levels of punishment after hydrocortisone, especially in the 20 mg group. Drug-induced salivary cortisol correlated negatively with punishment behavior. None of the other facets of social behavior or the SVO were affected by hydrocortisone. Our results suggest that hydrocortisone reduces the propensity to punish unfair behavior. Future studies are needed to further disentangle the role played by various psychobiological mechanisms within the stress response as well as their complex interplay on social behavior and cognition.

Academic Pediatrics 2021To assess US pediatricians' preparedness, motivation, and barriers related to educating parents about corporal punishment (CP) and effective child discipline.
OBJECTIVE
To assess US pediatricians' preparedness, motivation, and barriers related to educating parents about corporal punishment (CP) and effective child discipline.
METHODS
A random sample of 1500 pediatricians was drawn from a nationwide database in the United States. A self-administered questionnaire was sent via mail in 2016. The response rate (53%; n = 787) was maximized via repeated survey mailings and use of cash incentives.
RESULTS
The majority of respondents were White (69%), female (59%) and were members of the American Academy of Pediatrics (85%). Most pediatricians felt somewhat prepared to advise parents about child discipline, particularly CP, and perceived their colleagues to be slightly less prepared than themselves. Although most (72%) respondents believed it was "extremely/very" likely that parents valued their advice about child discipline, only 36% believed parents were "extremely/very" likely to follow their advice. Most respondents were highly motivated to participate in activities designed to change norms regarding CP. The most common strategy pediatricians identified for improving child behavior was being consistent with rules (71%). Perceived barriers to providing child discipline advice to parents included lack of time (90%), lack of insurance reimbursement (48%), and lack of training and educational resources (47%).
CONCLUSIONS
Pediatricians are a key source of professional advice for parents about how to discipline children safely. Given this, along with strong approval and use of CP in the United States and its harm for children, the current findings suggest a strong need for pediatricians to receive additional training on how to advise parents about child discipline along with removal of barriers to providing such advice.

Addictions are characterized by choices made to satisfy the addiction despite the risk it could produce an adverse consequence. Here, we developed a murine version of a 'risky decision-making' task (RDT), in which mice could respond on a touchscreen panel to obtain either a large milkshake reward associated with varying probability of footshock, or a smaller amount of the same reward that was never punished. Results showed that (the following font is incorrectly smaller/subscripted) mice shifted choice from the large to small reward stimulus as shock probability increased. Immunohistochemical analysis revealed more Fos-positive cells in prelimbic cortex (PL) and basal amygdala (BA) after RDT testing, and a strong anti-correlation between infralimbic cortex (IL) activity and choice of the large reward stimulus under likely (75-100 % probability) punishment. These findings establish an assay for risky choice in mice and provide preliminary insight into the underlying neural substrates.

Despite unresolved questions about replicability, a substantial number of studies find that disgust influences and arises from evaluations of immoral behavior and people. Departing from prior emphases, the current research examines a novel, related question: Are people who are viewed as disgusting (i.e., people whose habits seem disgusting) perceived as more immoral than typical or unusual people? Four experiments examined this, also exploring the downstream impacts of moral character judgments. Adults who seemed disgusting were regarded as more immoral for purity and non-purity violations (Experiment 1) and less praiseworthy for prosocial acts (Experiment 2). In Experiment 3, an 8-year-old with typical (but seemingly disgusting) habits was rated as "naughtier" and likelier to misbehave than an atypical child who loved vegetables and disliked sweets. Experiment 4 revealed how, when no behavioral information is available, beliefs about target disgust influence beliefs about future behavior, helping explain why seemingly disgusting targets are viewed as more immoral, but not always more punishable for their bad behavior.

Punishment involves learning the relationship between actions and their adverse consequences. Both the acquisition and expression of punishment learning depend on the basolateral amygdala (BLA), but how BLA supports punishment remains poorly understood. To address this, we measured calcium (Ca) transients in BLA principal neurons during punishment. Male rats were trained to press two individually presented levers for food; when one of these levers also yielded aversive footshock, responding on this punished lever decreased relative to the other, unpunished lever. In rats with the Ca indicator GCaMP6f targeted to BLA principal neurons, we observed excitatory activity transients to the footshock punisher and inhibitory transients to lever-presses earning a reward. Critically, as rats learned punishment, activity around the punished response transformed from inhibitory to excitatory and similarity analyses showed that these punished lever-press transients resembled BLA transients to the punisher itself. Systemically administered benzodiazepine (midazolam) selectively alleviated punishment. Moreover, the degree to which midazolam alleviated punishment was associated with how much punished response-related BLA transients reverted to their pre-punishment state. Together, these findings show that punishment learning is supported by aversion-coding of instrumental responses in the BLA and that the anti-punishment effects of benzodiazepines are associated with a reversion of this aversion coding.

Some human groups are organized hierarchically and some are distributed. Both types of groups occur in economic, political, and military domains, but it is unclear why hierarchical organizations are favored in certain contexts and distributed organizations are favored in others. I propose that these different organizational structures can be explained by human groups having different constraints on their ability to foster cooperation within the group. Human within-group cooperation is often maintained by monitoring and punishment. In hierarchical groups, monitoring and punishment are organized into tree-like command-and-control structures with supervisors responsible for monitoring the cooperation of their subordinates and punishing non-cooperators. By contrast, in distributed groups, monitoring is diffuse and punishment is collective. I propose that the organization of cooperative human groups is constrained by the costs of monitoring and punishment. I formalize this hypothesis with a model where individuals in a group cooperate to produce public goods while embedded in a network of monitoring and punishment responsibilities. I show that, when punishment costs are high and monitoring costs are low, socially-optimal monitoring and punishment networks are distributed. The size of these distributed networks is constrained by monitoring costs. However, when punishment costs are low, socially-optimal networks are hierarchical. Monitoring costs do not constrain the size of hierarchical networks but determine how many levels of supervision are required to foster cooperation in the hierarchical group. These results may explain the increasingly large and hierarchical groups throughout much of human history. They also suggest that the recent emergence of large-scale distributed organizations has been possible because new technologies, like the internet, have made monitoring costs extremely low.
