A widely accepted view holds that human infants’ knowledge of the world develops not from a single, general-purpose ability to reason about objects and events but instead from several “core” systems of knowledge, each specialized for representing and reasoning about entities of different kinds. One functionally specialized system concerns knowledge about animate creatures. If knowledge about an...

Almost all democratic societies evolved socially and politically out of authoritarian and nondemocratic regimes. These changes not only altered the allocation of economic resources in society but also the structure of political power. In this paper, we develop a framework for studying the dynamics of political and social change. The society consists of agents that care about current and future ...

Understanding the evolution of social behaviours such as altruism and spite is a long-standing problem that has generated thousands of articles and heated debates. Previous theoretical studies showed that whether altruism and spite evolve may be contingent on seemingly artificial model features, such as which rule is chosen to update the population (for example, birth-death or death-birth), and...

A difference in dominance rank is an often-usedcue to resolve con icts between two animals without escalated Ž ghts. At the group level, adherence to a dominance convention efŽ ciently reduces the costs associatedwith con icts, but from an individual’s point of view, it is difŽ cult to explainwhy a low ranking individualshould accept its subordinatestatus. This is especially true if, as sugge...

discrimination and detection of biological motion (Neri et al., 2006; Manera et al., 2011). This “inverse relationship” between bottom-up perceptual input and top-down social information implies the presence of “social” forward (internally generated) models acting as top-down priors, which may be competing with other internal models for overall control, comparable to forward models of action (W...

Visualization is a useful tool for understanding the nature of networks. The recent growth of social media requires more powerful visualization techniques beyond static network diagrams. One of the most important challenges is the visualization of temporal network evolution. In order to provide strong temporal visualization methods, we need to understand what tasks users accomplish. This study ...

The dress code of paper wasps, like that of humans, is related to their social habits: species with a flexible nest-founding strategy have highly variable black-and-yellow markings. This color polymorphism facilitates individual recognition and might have been selected to permit complex social interactions.
