Sociality—ie, life in social groups—has evolved many times in rodents, and there is
considerable variation in the nature of these groups. While many species-typical behaviors …

Social behavior is often described as a unified concept, but highly social (group-living)
species exhibit distinct social structures and may make different social decisions. Prairie …

Social interactions are a fundamental and adaptive component of the biology of numerous
species. Social recognition is critical for the structure and stability of the networks and …

Like many mammals, rats frequently engage in play fighting as juveniles, an activity that
influences the development of socio-cognitive skills. Most studies that assess play are based …

Group-living animals vary in social behavior across multiple dimensions, including in the
selectivity of social interactions with familiar versus unfamiliar peers. Standardized …

Existing assays of social interaction are suboptimal, and none measures propinquity, the
tendency of rodents to maintain close physical proximity. These assays are ubiquitously …

Exploring the neurobiological mechanisms of social behavior requires behavioral tests that
can be applied to animal models in an unbiased and observer-independent manner. Since …

Other-regarding preferences are considered to be the foundation of human cooperation.
However, the evolutionary origin of this behavior in humans remains poorly understood. So …

All mammals begin life in social groups, but for some species, social relationships persist
and develop throughout the course of an individual's life. Research in multiple rodent …

Mouse models of social dysfunction, designed to investigate the complex genetics of social
behaviors, require an objective methodology for scoring social interactions relevant to …
