For social omnivores such as rats and humans, taste is far more than a chemical sense activated by food. By virtue of evolutionary and epigenetic elaboration, taste is associated with negative affect, stress vulnerability, responses to psychoactive substances, pain, and social judgment. A crucial gap in this literature, which spans behavior genetics, affective and social neuroscience, and embodied cognition, concerns links between taste and social behavior in rats. Here we show that rats selectively bred for low saccharin intake are subordinate to high-saccharin-consuming rats when they compete in weight-matched dyads for food, a task used to model depression. Statistical and …

The urgent need for peace—if not immediately, everywhere, at any cost, then soon, as a pervasive norm—coincides with unprecedented scholarly attention to peace and to the implications of evolution for psychological functioning in the context of complex sociality.

Toward that end, this chapter describes potential impediments to an evolutionary peace project, provides a basic lexical and conceptual tool kit, …

Engaging in research of any kind is a privilege that carries with it weighty ethical responsibilities and opportunities. Laboratory (“lab”) animal research is a scholarly enterprise that has played an important role in the development of psychology as a science, including the development of its ethical dimensions. Much has been written on the subject, and a thorough review is beyond the scope of this chapter. Here, we articulate a practical, educational approach to the ethical care and use of lab animals in psychology in the United States. The usefulness of our suggestions will vary depending on readers’ prior knowledge, as …
