| Open AccessPartner choice and cooperation in social dilemmas can increase resource inequality
Cooperation is more likely when individuals can choose their interaction partner. However, here, the authors show that partner choice can increase resource inequality in a public goods game when people differ in resources and productivity needed for cooperation.

| Open AccessDevelopment and validation of the pandemic fatigue scale
In this study the authors introduce a measure of pandemic fatigue and report the existence of, and changes in, pandemic fatigue during the COVID-19 pandemic. They also identify correlates of pandemic fatigue and show that those who experienced more pandemic fatigue were less likely to adhere to various health-protective behaviors.

| Open AccessTime-dependent memory transformation in hippocampus and neocortex is semantic in nature
Memories are transformed over time. Here, the authors show that this transformation is semantic in nature and linked to transformed event representations in neocortex and increased pattern reinstatement in the posterior hippocampus, while they find no credible evidence for a perceptual transformation.

| Open AccessCross-national analyses require additional controls to account for the non-independence of nations
Nations are connected in many ways, yet cross-national analyses often assume they are independent. Here, the authors show that previous studies may not have sufficiently accounted for this non-independence of nations.

| Open AccessAction initiation and punishment learning differ from childhood to adolescence while reward learning remains stable
Adolescence is often associated with heightened reward learning and impulsivity. Here the authors show in 742 people aged 9-18 that reward learning in fact remains stable with age, whilst punishment learning increases and action initiation decreases.

| Open AccessNeurofunctional underpinnings of individual differences in visual episodic memory performance
The neural basis of individual differences in episodic memory performance is not well understood. Here, the authors show in a large fMRI dataset that activity of the hippocampus, orbitofrontal cortex and posterior cingulate cortex accounts for individual variability in memory performance.

| Open AccessMultifaceted information-seeking motives in children
Knowledge can impact children’s emotion, cognition, and action. The authors show that when seeking information, children consider if information is useful, positive, and lowers uncertainty, with the emphasis on these considerations changing with age.

| Open AccessSubjective socioeconomic status and income inequality are associated with self-reported morality across 67 countries
People differ in the extent to which they experience a lack of economic resources compared to others. Here, the authors show that such experiences at the individual level as well as income inequality at the national level are associated with self-reported morality-related outcomes.

| Open AccessAnxious individuals shift emotion control from lateral frontal pole to dorsolateral prefrontal cortex
Why anxious individuals fail to control emotional behaviour is not well understood. Here, the authors show that highly anxious individuals have a more excitable lateral frontopolar cortex, and fail to recruit this region during emotional action control.

| Open AccessNeural signatures of social inferences predict the number of real-life social contacts and autism severity
How our ability to infer the cognitive and emotional states of other people manifests in both neural activity and real-world social behavior is not fully understood. Here, the authors show neural activation patterns in the right posterior superior temporal sulcus during a social inference task predict the number of social contacts in both neurotypical and autism groups.

| Open AccessRe-expression of CA1 and entorhinal activity patterns preserves temporal context memory at long timescales
How hippocampal area CA1 and the entorhinal cortex preserve temporal memories over long timescales is not known. Here, the authors show using 7T fMRI, that temporal context memory for scene images is predicted by the re-expression of CA1 and entorhinal cortex activity patterns during subsequent encounters over a period of months.

| Open AccessTask state representations in vmPFC mediate relevant and irrelevant value signals and their behavioral influence
The ventromedial prefrontal-cortex (vmPFC) encodes expected value signals that contribute to choices. Here the authors show that during decision-making the human ventromedial prefrontal cortex contains a task-context representation that arbitrates between simultaneously active representations of expected values in the current versus other task contexts.
