The Impacts of the Presence of an Unfamiliar Dog on Emerging Adults’ Physiological and Behavioral Responses Following Social Exclusion

Abstract

Research indicates that non-human attachment figures may mitigate the negative consequences of social exclusion. In the current experiment, we examined how the presence of an unfamiliar companion dog in the laboratory effects physiological and behavioral reactions in female emerging adults after social exclusion compared to inclusion. Results revealed the beneficial effects of the dog: Socially excluded participants in the company of a dog showed less aggressive behavior in response to the hot sauce paradigm compared to excluded participants in the control condition. Furthermore, cardiac responses indicated mitigated perception of threat in a subsequent insult episode when a dog was present. The presence of a dog did not impact the most instantaneous, “reflexive” response to the social exclusion as revealed by characteristic cardiac changes. Together, the findings indicate that the presence of a companion dog takes effect in a later, reflective period following a social exclusion experience, which implicates relevant social elaboration and appraisal processes.
