Beyond egalitarian societies: Egalitarianism as a human universal - Volume 49

Childhood is a key period for acquiring and transmitting cultural knowledge and skill. Hunter-gatherer children, such as the Congolese BaYaka, learn a…

Humans rely on complex social learning and collective adaptation to navigate dynamically changing environments. The authors show that human collective intelligence in a dynamic, naturalistic task depe...

Objectives Caregiving during early childhood emerges from a dynamic interplay between maternal and allomaternal contributions. This study aimed to challenge polarized portrayals of hunter-gatherer c...

Understanding human decision-making processes in everyday life is a central, yet rarely addressed, challenge in psychology. Either real-life complexity is reduced by isolating specific aspects of decision-making in highly constrained experimental settings, yielding insights into specific cognitive mechanisms under idealized conditions, or decision-making is studied in real-life contexts, using high-level descriptions of behavior that do not afford fine-grained, process-level insights. Bridging this gap poses a challenge of both measurement and inference. Recent advances in high-resolution tracking technologies provide novel solutions to many measurement challenges but are rarely integrated with formal psychological theory. In this article, we review tracking technologies and statistical tools, proposing a cognitive–computational framework that uses high-resolution spatiotemporal data to investigate the mechanisms of real-life decision-making in a theory-driven manner.

Faced with anthropogenic change, animals now encounter challenges different from their evolutionary past. To cope with such challenges, animals may use social information about others' affective stat...

Levodopa restores the balance between exploration and exploitation in Parkinson’s disease.

When psychological researchers investigate binary outcomes, they routinely report odds ratios to quantify the strength of an effect or an association. This is quite understandable given that psycholog...

We develop a demographic theory of similarity-biased social learning that formalizes our understanding of when and why individuals should preferent...

Humans adapt learning rates on both a fast and a slow time scale, and the central orbitofrontal cortex may represent the slow time scale.

Children as agents of cultural adaptation - Volume 49

– by Haneul Jang For decades, the phrase Man the Hunter has occupied a central place in discussions of human evolution. Today, however, the phrase sounds outdated, evoking a familiar image of men hunt...

Abstract. A necessary prerequisite for the accumulation of beneficial knowledge, or ‘cumulative cultural evolution’, is the sharing of information via soci
