The Time Paradox by the celebrated psychologist Philip Zimbardo and Director of Design Research at Yahoo!, John Boyd, is a popular psychology title that explains the new psychological science of time and the authors' unprecedented studies on time perspective, covering 40 years of research. It's also a self-help guide to understanding how your perceptions on time influence every facet of your life and a lively social commentary on the power of time in our modern world.

Philip Zimbardo, renowned for his 1971 Stanford Prison Experiment, is one of the most distinguished psychologists alive today. A professor emeritus at Stanford University, he served as president of the American Psychological Association, designed and narrated the award-winning PBS series, Discovering Psychology, and has published several hundred professional articles and 50 books. His areas of focus include time perspective, shyness, evil, and madness.

In The Time Paradox Zimbardo and Boyd reveal that there are multiple perceptions of time. More than any other single factor—emotion, intelligence, relationships, stress, traffic, snap judgments, and mess—time permeates every facet of our lives. Our attitudes toward time are the most powerful influence on how we think, feel, and act, every day or our lives.

Paul Ekman, the world's foremost expert on facial expressions and a professor emeritus at the University of California Medical School in San Francisco, lectures on a landmark conversation between him and Tenzin Gyatzo, the 14th Dalai Lama, as it is documented in the new book, Emotional Awareness: Overcoming Obstacles to Psychological Balance and Compassion (Henry Holt & Co., 2008).

Ekman's research on facial expression and body movement, begun in 1954, led to his development of the Facial Action Coding System (FACS) to taxonomize every conceivable human facial expression. In addition to his basic research on emotion and its expression, he has studied deceit for the last 30 years.

Currently, he is the director of the Paul Ekman Group, LLC, a small company that produces training devices relevant to emotional skills, and is initiating new research relevant to national security and law enforcement.

Articles reporting on Dr. Ekman's work have appeared in Time Magazine, Smithsonian Magazine, Psychology Today, The New Yorker and others, both American and foreign. Numerous articles about his work have also appeared in the New York Times, Washington Post and other national newspapers.

He has appeared on 48 Hours, Dateline, Good Morning America, 20/20, Larry King, Oprah, Johnny Carson, and many other TV programs. He has also been featured on various public television programs such as News Hour with Jim Lehrer, and Bill Moyers' The Truth About Lying.
