| Open AccessNeurocomputational mechanisms involved in adaptation to fluctuating intentions of others
Humans often interact without knowing the cooperative or competitive intentions of others. Here, the authors determined the neurocomputational mechanisms engaged in adapting to fluctuating intentions of others over repeated social interactions.

| Open AccessDynamics of collective cooperation under personalised strategy updates
Collective cooperation is found across many social and biological systems. Here, the authors find that infrequent hub updates promote the emergence of collective cooperation and develop an algorithm that optimises collective cooperation with update rates.

| Open AccessThe psychological, computational, and neural foundations of indebtedness
Receiving a favour may induce a feeling of indebtedness in a beneficiary. Here, the authors develop and validate a model that captures the psychological, computational, and neural bases of how indebtedness arises and influences reciprocity behaviour.

| Open AccessAmylin-Calcitonin receptor signaling in the medial preoptic area mediates affiliative social behaviors in female mice
The mechanisms coordinating the sensing and seeking of social contacts are unclear. Here, the authors show that amylin-calcitonin receptor signalling in the media preoptic area mediates affiliative social behaviors in female mice.

| Open AccessNeural computations underlying strategic social decision-making in groups
The brain mechanisms underlying cooperation within groups, while balancing individual and collective interests, are poorly understood. Here, the authors identify the neurocomputations engaged in social dilemmas requiring strategic decisions during repeated social interactions in groups.

| Open AccessNeural representations of honesty predict future trust behavior
We tend to be more trusting of people who we know to be honest. Here, the authors show using fMRI that honesty-based trustworthiness is represented in the posterior cingulate cortex, dorsolateral prefrontal cortex and intraparietal sulcus, and predicts subsequent trust decisions.

| Open AccessDuets recorded in the wild reveal that interindividually coordinated motor control enables cooperative behavior
Recording neural activity during coordinated behaviors in controlled environments limits opportunities for understanding natural interactions. Here, the authors record from freely moving duetting birds in their natural habitats to reveal the neural mechanisms of interindividual motor coordination.

| Open AccessDispositional free riders do not free ride on punishment
Strong positive and strong negative reciprocators reward cooperation and punish defection, respectively, regardless of future benefits. Here, Weber and colleagues demonstrate that dispositions towards strong positive and strong negative reciprocity are not correlated within individuals.

| Open AccessCrosstalk in concurrent repeated games impedes direct reciprocity and requires stronger levels of forgiveness
Social interactions among people are often repeated, and yet it is assumed that simultaneous interactions are independent from one another. Here, Reiter and colleagues describe a conceptual framework where an action in one game can influence the decision in another.

| Open AccessA neural link between generosity and happiness
Generous behaviour increases happiness, but the neural underpinnings of this link are unknown. Here, authors show that promising to be generous changes the neural response in the temporo-parietal junction, and that the connection between this region and the ventral striatum was related to happiness.

| Open AccessResilient cooperators stabilize long-run cooperation in the finitely repeated Prisoner’s Dilemma
Studying the dynamics of learning in repeated games of cooperation is complicated by the short duration of traditional experiments. Here the authors perform a virtual prisoner's dilemma game over twenty consecutive days, finding that a minority of resilient co-operators can sustain cooperation indefinitely.

Humans display a ‘cooperative phenotype’ that is domain general and temporally stable
It is generally assumed that a person’s cooperative behaviour is consistent, but direct evidence is lacking. Here, the authors show consistent patterns of an individual’s behaviour both in different cooperation games and through time, suggesting that an individual's cooperative behaviour is general and stable.

The evolutionary origin of human hyper-cooperation
The evolutionary foundation of human prosociality remains poorly understood. Here, the authors show that extensive allomaternal care is the best predictor of prosocial behaviour among 15 primate species, including humans, which suggests that prosocial motivations arise along with cooperative breeding.

Transition from reciprocal cooperation to persistent behaviour in social dilemmas at the end of adolescence
Human societies are cooperative, yet the propensity to cooperate may vary with age. Here, Gutierrez-Roig et al.show that, while in adults the decision of whether or not to cooperate is based on previous actions, teenagers mostly follow the decisions of their peers, regardless of their previous actions.

Social heuristics shape intuitive cooperation
Whether or not intuition favours cooperative decision making has been controversial. Rand et al.carry out a meta-analysis of 15 studies involving volunteers playing economic games, and confirm a role for intuition in cooperation, which varies according to the volunteers’ previous experience with similar games.
