All creatures great and small: new perspectives on psychology and human–animal interactions

Relations between humans and nonhuman animals are morally significant, intense, enduring, and pervasive. Presented here are current perspectives on social and psychological aspects of human–animal interactions. The articles in this issue focus on three broad themes—attitudes toward the use of other species, the effects of relationships with companion animals on human health and well-being, and the ethical and policy implications of our interactions with other species. The article represent a mix of theory, qualitative and quantitative empirical approaches, review, and policy recommendations on a topic that has historically been neglected by social scientists.
