THIS EMOTIONAL LIFE is a three-part series that takes viewers on an in-depth tour of the science of human emotions in an effort to truly understand what makes us tick. Every day, it seems, some new study reveals a previously hidden epidemic of depression, anxiety or other psychological problem. At the root of the confusion lie three key questions: what is biological, what is cultural and what can we do when things go wrong? After centuries of assuming that we humans, with our mysterious minds and messy emotions, were just not fit subjects for study, science has developed some startling insights into human nature. Using the latest cutting edge research from neuroscience, startling observations from social science and experts in psychology, THIS EMOTIONAL LIFE explores the biological need for social relationships, how to manage negative feelings and the search for greater happiness, unveiling a new understanding of what it means to be human.
