A novel approach to understanding personality, based on evidence that we share more than we realize with other mammals.

This book presents the wealth of scientific evidence that our personality emerges from evolved primary emotions shared by all mammals. Yes, your dog feels love—and many other things too. These subcortically generated emotions bias our actions, alter our perceptions, guide our learning, provide the basis for our thoughts and memories, and become regulated over the course of our lives.

Understanding personality development from the perspective of mammals is a groundbreaking approach, and one that sheds new light on the ways in which we as humans respond to life events, both good and bad.
