Humans are a social species. From the very beginning of life, we grow within a social environment, cooperate and bind with conspecifics, and care for each other. Lack of social connection has serious consequences, culminating in an increased chance of early death by 20%. The sensory determinants of human sociality have been largely investigated, and a growing body of evidence indicates that body odors convey a wealth of information about an individual’s traits (e.g., identity, age) and states (e.g., emotion, health status). This symposium will offer recent insights on how human chemosignals foster sociality across a variety of relational contexts and developmental stages.
