Abstract

Human cooperation is probably supported by our tendency to punish selfishness in others. Social norms play an important role in motivating third-party punishment (TPP), and also in explaining societal differences in prosocial behaviour. However, there has been little work directly linking social norms to the development of TPP across societies. In this study, we explored the impact of normative information on the development of TPP in 603 children aged 4–14, across six diverse societies. Children began to perform TPP during middle childhood, and the developmental trajectories of this behaviour were similar across societies. We also found that social norms began to influence the likelihood of performing TPP during middle childhood in some of these societies. Norms specifying the punishment of selfishness were generally more influential than norms specifying the punishment of prosocial behaviour. These findings support the view that TPP of selfishness is important in all societies, and its development is shaped by a shared psychology for responding to normative information. Yet, the results also highlight the important role that children's prior knowledge of local norms may play in explaining societal variation in the development of both TPP and prosociality.

From the Conclusion and Discussion Section

Children's bias towards punishing selfish third parties increased during middle childhood, and this developmental pattern is similar across societies. Middle childhood is also when children across diverse societies become more prosocial and more averse to advantageous inequity. This raises the possibility that prosociality, advantageous inequity aversion and TPP may be developmentally coupled. In each of these cases, individuals incur personal costs to produce fairer outcomes for others. One explanation for this is that children become more responsive to social norms during middle childhood, leading them to become more likely to conform to social norms. This is consistent with our finding that norm primes begin to shape behaviour during middle childhood (although TPP norm primes were not effective in all societies).

Punish the Perpetrator or Compensate the Victim?

Abstract

Third-party punishment and third-party compensation are primary responses to observed norms violations. Previous studies mostly investigated these behaviors in gain rather than loss context, and few study made direct comparison between these two behaviors. We conducted three experiments to investigate third-party punishment and third-party compensation in the gain and loss context. Participants observed two persons playing Dictator Game to share an amount of gain or loss, and the proposer would propose unfair distribution sometimes. In Study 1A, participants should decide whether they wanted to punish proposer. In Study 1B, participants decided to compensate the recipient or to do nothing. This two experiments explored how gain and loss contexts might affect the willingness to altruistically punish a perpetrator, or to compensate a victim of unfairness. Results suggested that both third-party punishment and compensation were stronger in the loss context. Study 2 directly compare third-party punishment and third-party compensation in the both contexts, by allowing participants choosing between punishment, compensation and keeping. Participants chose compensation more often than punishment in the loss context, and chose more punishments in the gain context. Empathic concern partly explained between-context differences of altruistic compensation and punishment. Our findings provide insights on modulating effect of context on third-party altruistic decisions.

Abstract

Understanding the roots of prosocial behavior is an interdisciplinary research endeavor that has generated an abundance of empirical data across many disciplines. This review integrates research findings from different fields into a novel theoretical framework that can account for when prosocial behavior is likely to occur. Specifically, we propose that the motivation to cooperate (or not), generated by the reward system in the brain (extending from the striatum to the ventromedial prefrontal cortex), is modulated by two neural networks: a cognitive control system (centered on the lateral prefrontal cortex) that processes extrinsic cooperative incentives, and/or a social cognition system (including the temporo-parietal junction, the medial prefrontal cortex and the amygdala) that processes trust and/or threat signals. The independent modulatory influence of incentives and trust on the decision to cooperate is substantiated by a growing body of neuroimaging data and reconciles the apparent paradox between economic versus social rationality in the literature, suggesting that we are in fact wired for both. Furthermore, the theoretical framework can account for substantial behavioral heterogeneity in prosocial behavior. Based on the existing data, we postulate that self-regarding individuals (who are more likely to adopt an economically rational strategy) are more responsive to extrinsic cooperative incentives and therefore rely relatively more on cognitive control to make (un)cooperative decisions, whereas other-regarding individuals (who are more likely to adopt a socially rational strategy) are more sensitive to trust signals to avoid betrayal and recruit relatively more brain activity in the social cognition system. Several additional hypotheses with respect to the neural roots of social preferences are derived from the model and suggested for future research.

6. Concluding remarks and directions for future research

Prosociality includes a wide array of behavior, including mutual cooperation, pure altruism, and the costly act of punishing norm violators. Neurologically, these behaviors are all motivated by neural networks dedicated to reward, indicating that prosocial acts (such as cooperating in a social dilemma) are carried out because they were desired and feel good. However, the underlying reasons for the pleasant feelings associated with cooperative behavior may differ. First, cooperation may be valued because of accruing benefits, making it economically rational. This route to cooperation is made possible through brain regions in the lateral frontal cortex that generate cognitive control and process the presence or absence of extrinsic cooperative incentives. Second, consistent with proponents of social rationality, cooperation can also occur when people expect to experience reward through a “warm glow of giving.” Such intrinsically motivated cooperation yields collective benefits from which all group members may eventually benefit, but it can only be sustained when it exists in concert with a mechanism to detect and deter free-riding. Hence socially rational cooperation is facilitated by a neural network dedicated to social cognition that processes trust signals.
