The Twenty Four Hour Mind

In The Twenty-four Hour Mind, sleep researcher Rosalind Cartwright brings together decades of research into the bizarre sleep disorders known as 'parasomnias' to propose a new theory of how the human brain works consistently throughout waking and sleeping hours, based upon research showing that one of the primary purposes of sleep is to aid in regulating emotions and processing experiences that occur during waking hours.

In January of 1997, an otherwise nonviolent man under great stress at work brutally murdered his wife in their backyard. He then went back to bed, awakening only when police entered his home. He claimed to have no memory of the event because, while his body was awake at the time, his mind was not. He had been sleepwalking.In The Twenty-four Hour Mind, sleep scientist Rosalind Cartwright brings together decades of research into the bizarre sleep disorders known as parasomnias to propose a new theory of how the human mind works consistently throughout waking and sleeping hours. Thanks to increasingly sophisticated EEG and brain imaging technologies, we now know that our minds do not simply "turn off" during sleep. Rather, they continue to be active, and research has indicated that one of the primary purposes of sleep is to aid in regulating emotions and processing experiences that occur during preceding waking hours. As such, when sleep is neurologically or genetically impaired or just too short, the processes that good sleep facilitates--those that usually have a positive effect on our mood and performance--can short circuit, with negative results that occasionally reach tragic proportions. Examining the interactions between conscious and unconscious forms of thinking as they proceed throughout the cycles of sleeping, dreaming, and waking, Cartwright demystifies the inner workings of the human mind that trigger sleep problems, how researchers are working to control them, and how they can apply what they learn to further our understanding of the brain. Along the way, she provides a lively account of the history of sleep research and the birth of sleep medicine that will initiate readers into this fascinating field of inquiry and the far-reaching implications it will have on the future of neuroscience. The Twenty-four Hour Mind offers a unique look at a relatively new area of study that will be of interest to those with and without sleep problems, as well as anyone captivated by the mysteries of the brain--and what sleep continues to teach us about the waking mind.

"Sleep is one of the most important but least understood aspects of our life, wellness, and longevity ... An explosion of scientific discoveries in the last twenty years has shed new light on this fundamental aspect of our lives. Now ... neuroscientist and sleep expert Matthew Walker gives us a new understanding of the vital importance of sleep and dreaming"--Amazon.com.

Rosalind Cartwright, Ph.D. and Lynne Lamberg present new evidence that dreams are coherent symbolic reflections of the dreamer's mental state. They show that you can learn about yourself and your problems by studying your dreams. Crisis Dreaming provides simple, effective strategies for remembering your dreams and for "rewriting" better dream scripts while you sleep. These tactics are based on Dr. Cartwright's more than 25 years of scientific research. You can carry the insight you gain from your dreams into your waking life to help resolve depression and anxiety brought on by divorce, bereavement, serious illness, job loss, and other crises. In this book, you'll meet people who learned, with Dr. Cartwright's help, to use their dreams to change their daily lives. They gained control over the demons that plagued them. By following the guidelines in this book, you can achieve that goal, too.

National Book Award Finalist: “This man’s ideas may be the most influential, not to say controversial, of the second half of the twentieth century.”—Columbus Dispatch At the heart of this classic, seminal book is Julian Jaynes's still-controversial thesis that human consciousness did not begin far back in animal evolution but instead is a learned process that came about only three thousand years ago and is still developing. The implications of this revolutionary scientific paradigm extend into virtually every aspect of our psychology, our history and culture, our religion—and indeed our future. “Don’t be put off by the academic title of Julian Jaynes’s The Origin of Consciousness in the Breakdown of the Bicameral Mind. Its prose is always lucid and often lyrical…he unfolds his case with the utmost intellectual rigor.”—The New York Times “When Julian Jaynes . . . speculates that until late in the twentieth millennium BC men had no consciousness but were automatically obeying the voices of the gods, we are astounded but compelled to follow this remarkable thesis.”—John Updike, The New Yorker “He is as startling as Freud was in The Interpretation of Dreams, and Jaynes is equally as adept at forcing a new view of known human behavior.”—American Journal of Psychiatry

An engrossing examination of the science behind the little-known world of sleep. Like many of us, journalist David K. Randall never gave sleep much thought. That is, until he began sleepwalking. One midnight crash into a hallway wall sent him on an investigation into the strange science of sleep. In Dreamland, Randall explores the research that is investigating those dark hours that make up nearly a third of our lives. Taking readers from military battlefields to children’s bedrooms, Dreamland shows that sleep isn't as simple as it seems. Why did the results of one sleep study change the bookmakers’ odds for certain Monday Night Football games? Do women sleep differently than men? And if you happen to kill someone while you are sleepwalking, does that count as murder? This book is a tour of the often odd, sometimes disturbing, and always fascinating things that go on in the peculiar world of sleep. You’ll never look at your pillow the same way again.

Over the last few decades, economists and psychologists have quietly documented the many ways in which a person's IQ matters. But, research suggests that a nation's IQ matters so much more. As Garett Jones argues in Hive Mind, modest differences in national IQ can explain most cross-country inequalities. Whereas IQ scores do a moderately good job of predicting individual wages, information processing power, and brain size, a country's average score is a much stronger bellwether of its overall prosperity. Drawing on an expansive array of research from psychology, economics, management, and political science, Jones argues that intelligence and cognitive skill are significantly more important on a national level than on an individual one because they have "positive spillovers." On average, people who do better on standardized tests are more patient, more cooperative, and have better memories. As a result, these qualities—and others necessary to take on the complexity of a modern economy—become more prevalent in a society as national test scores rise. What's more, when we are surrounded by slightly more patient, informed, and cooperative neighbors we take on these qualities a bit more ourselves. In other words, the worker bees in every nation create a "hive mind" with a power all its own. Once the hive is established, each individual has only a tiny impact on his or her own life. Jones makes the case that, through better nutrition and schooling, we can raise IQ, thereby fostering higher savings rates, more productive teams, and more effective bureaucracies. After demonstrating how test scores that matter little for individuals can mean a world of difference for nations, the book leaves readers with policy-oriented conclusions and hopeful speculation: Whether we lift up the bottom through changing the nature of work, institutional improvements, or freer immigration, it is possible that this period of massive global inequality will be a short season by the standards of human history if we raise our global IQ.
