Social hierarchies guide behavior in many species, including humans, where status also has an enormous impact on motivation and health. However, little is known about the underlying neural representation of social hierarchies in humans. In the present study, we identify dissociable neural responses to perceived social rank using functional magnetic resonance imaging (fMRI) in an interactive, si...

The perception and judgement of social hierarchies forms an integral part of social cognition. Hierarchical judgements can be either self-referential or allocentric (pertaining to two or more external agents). In psychiatric conditions such as dissocial personality disorder and schizophrenia, the impact of hierarchies may be problematic. We sought to elucidate the brain regions involved in judg...

http://dx.doi.org/10.1016/j.anbehav.2016.03.004 0003-3472/© 2016 The Association for the Study of A Dominance hierarchies emerge when individuals must compete for access to resources such as food, territory or mates. Here, using traditional and network social hierarchy analysis, we show that 10 groups of 12 male laboratory CD1 mice living in large vivaria consistently form extremely linear domi...

The high/low hierarchy respects the ordering of degrees, and so we can expect to find properties of order which are possessed by all degrees in a given hierarchy class. Such properties can also be found for classes of the generalized high/low hierarchy even though that hierarchy does not respect the ordering of the degrees. For example, Jockusch and Posner [4], extending a result of Cooper [l],...

The Bonabeau model attempts to explain the origin of hierarchical structure in society on the basis of random aggressive interactions between agents in the society. Agents which win most of their fights rise higher in the hierarchy, while those who lose most fights occupy the lower tiers. This model grew out of ethological studies on eusocial wasps, but has been subsequently modified to represe...

The power law is ubiquitous in natural and social phenomena, and is considered as a universal relationship between the frequency and its rank for diverse social systems. However, a general model is still lacking to interpret why these seemingly unrelated systems share great similarity. Through a detailed analysis of natural language texts and simulation experiments based on the proposed ‘Hierar...
