This is the book I've been waiting for. The field has needed a clear and thorough review of anxiety, and now it exists. Joseph LeDoux, PhD, author, The Emotional Brain and Synaptic Self Center for Neural Science, New York University Anxiety 101, written by two prominent figures in the field of anxiety research, provides a thorough introduction to the concept of anxiety, placing it in the broad matrix of human concerns. The authors address evolutionary origins of anxiety, functions that anxiety and fear play in maintaining life, and ways in which these emotions can get out of control. An excellent introduction to students who want to understand the many ways in which scientists have approached the topic of anxiety. Charles S. Carver, PhD, Distinguished Professor of Psychology.
