In fact, a plethora of parasites affect our behavior in ways we have barely begun to understand.  In this mind-bending book, McAuliffe reveals the eons-old war between parasites and other creatures that is playing out in our very own bodies. And more surprising still, she uncovers the decisive role that parasites may have played in the rise and demise of entire civilizations. Our obsession with cleanliness and our experience of disgust are both evolutionary tools for avoiding infection, but they evolved differently for different populations. Political, social, and religious differences among societies may be caused, in part, by the different parasites that prey on us. In the tradition of Jared Diamond’s Guns, Germs, and Steel and Neil Shubin’s Your Inner Fish, This Is Your Brain on Parasites is both a journey into cutting-edge science and a revelatory examination of what it means to be human.

    It argues that evolution designed us both to teach and learn, and that the drive to learn is our most important instinct. It also reveals as fascinating insights about our adult capacities and how even young children -- as well as adults -- use some of the same methods that allow scientists to learn so much about the world. Filled with surprise at every turn, this vivid, lucid, and often funny book gives us a new view of the inner life of children and the mysteries of the mind.

    It was inside, inside my head, where all had become so wretchedly different. I had the night before been incontrovertibly a man of stable mood, of calm, of good cheer and unforced bonhomie. Now I had become changed, with dreadful suddenness, into another being altogether.”Simon Winchester has never shied away from big, even enormous, topics—as evidenced by his bestselling biography of the Atlantic Ocean, his account of the Krakatoa volcanic eruption, and his wildly popular “The Professor and the Madman,” about the making of the Oxford English Dictionary. In his Byliner Original “The Man with the Electrified Brain,” he takes on arguably his most daunting subject yet: his own flirtation with madness, and one of nature’s greatest and most enduring mysteries, the human brain. As a geology student in his second year at Oxford, Winchester was known as a young man of even temper and keen intellect, until one June morning when he woke to find himself “changed with dreadful suddenness into another being altogether,” his normal life “slumped into chasm” and “folded in the dirt.” For a period of nine days, he lived in immobilizing fear. Everyday items—familiar paintings, a pile of books, his own robe hanging from a hook—became objects of horror; the world lost color, purpose, all sense and safety. When the episode finally passed, he returned to normal, presuming that what had happened to him was a fluke. It wasn’t. The episode repeated itself at unpredictable and dangerous intervals for four years—always lasting for nine days—and very nearly caused the author’s death while he was on an expedition in the Arctic. What was wrong with him? Where could he find help? Would he spend the rest of his life anticipating the return of these mental blackouts? With the urgency of a whodunit, Winchester describes the coming and going of these terrifying dissociative states and the chance encounter that led to the controversial treatment of electroconvulsive therapy, which may or may not have cured him once and for all. Written by a consummate storyteller, “The Man with the Electrified Brain” locates that finest of lines between sanity and insanity and is Winchester’s most riveting and deeply personal work yet.

    Can a person think herself to orgasm? Why doesn't Viagra help women-or, for that matter, pandas? Can a dead man get an erection? Is vaginal orgasm a myth? Mary Roach shows us how and why sexual arousal and orgasm-two of the most complex, delightful, and amazing scientific phenomena on earth-can be so hard to achieve and what science is doing to make the bedroom a more satisfying place.

    From Washington to Wall Street, the classroom to the workplace, unethical behavior is everywhere. None of us is immune, whether it's the white lie to head off trouble or padding our expense reports. In The (Honest) Truth About Dishonesty, award-winning, bestselling author Dan Ariely turns his unique insight and innovative research to the question of dishonesty.Generally, we assume that cheating, like most other decisions, is based on a rational cost-benefit analysis. But Ariely argues, and then demonstrates, that it's actually the irrational forces that we don't take into account that often determine whether we behave ethically or not. For every Enron or political bribe, there are countless puffed résumés, hidden commissions, and knockoff purses. In The (Honest) Truth About Dishonesty, Ariely shows why some things are easier to lie about; how getting caught matters less than we think; and how business practices pave the way for unethical behavior, both intentionally and unintentionally. Ariely explores how unethical behavior works in the personal, professional, and political worlds, and how it affects all of us, even as we think of ourselves as having high moral standards.But all is not lost. Ariely also identifies what keeps us honest, pointing the way for achieving higher ethics in our everyday lives. With compelling personal and academic findings, The (Honest) Truth About Dishonesty will change the way we see ourselves, our actions, and others.

    But as scientists break open the mind’s black box with the latest tools of neuroscience, they’re discovering that this is not how the mind works. Our best decisions are a finely tuned blend of both feeling and reason—and the precise mix depends on the situation. When buying a house, for example, it’s best to let our unconscious mull over the many variables. But when we’re picking a stock, intuition often leads us astray. The trick is to determine when to use the different parts of the brain, and to do this, we need to think harder (and smarter) about how we think.Jonah Lehrer arms us with the tools we need, drawing on cutting-edge research as well as the real-world experiences of a wide range of “deciders”—from airplane pilots and hedge fund investors to serial killers and poker players.Lehrer shows how people are taking advantage of the new science to make better television shows, win more football games, and improve military intelligence. His goal is to answer two questions that are of interest to just about anyone, from CEOs to firefighters: How does the human mind make decisions? And how can we make those decisions better?

    This sense of our self may seem incredibly real but a wealth of recent scientific evidence reveals that it is not what it seems--it is all an illusion. In The Self Illusion, Bruce Hood reveals how the self emerges during childhood and how the architecture of the developing brain enables us to become social animals dependent on each other. Humans spend proportionally the greatest amount of time in childhood compared to any other animal. It's not only to learn from others, Hood notes, but also to learn to become like others. We learn to become our self. Even as adults we are continually developing and elaborating this story, learning to become different selves in different situations--the work self, the home self, the parent self. Moreover, Hood shows that this already fluid process--the construction of self--has dramatically changed in recent years. Social networking activities--such as blogging, Facebook, LinkedIn, and Twitter--are fast becoming socialization on steroids. The speed and ease at which we can form alliances and relationships are outstripping the same selection processes that shaped our self prior to the internet era. Things will never be the same again in the online social world. Hood offers our first glimpse into this unchartered territory. Who we are is, in short, a story of our self--a narrative that our brain creates. Like the science fiction movie, we are living in a matrix that is our mind. But Hood concludes that though the self is an illusion, it is an illusion we must continue to embrace to live happily in human society.

    As Dr. Kent Kiehl shows, psychopaths can be identified by a checklist of symptoms that includes pathological lying; lack of empathy, guilt, and remorse; grandiose sense of self-worth; manipulation; and failure to accept one’s actions. But why do psychopaths behave the way they do? Is it the result of their environment— how they were raised—or is there a genetic compo­nent to their lack of conscience? This is the question Kiehl, a protégé of famed psychopath researcher Dr. Robert Hare, was deter­mined to answer as he began his career twenty years ago. To aid in his quest to unravel the psy­chopathic mind, Kiehl created the first mobile functional MRI scanner to study psychopaths in prison populations. The brains of more than five hundred psychopaths and three thousand other offenders have been scanned by Kiehl’s labora­tory—the world’s largest forensic neuroscience repository of its kind. Over the course of The Psy­chopath Whisperer, we follow the scientific bread crumbs that Kiehl uncovered to show that the key brain structures that correspond with emotional engagement and reactions are diminished in psy­chopaths, offering new clues to how to predict and treat the disorder. In The Psychopath Whisperer, Kiehl describes in fascinating detail his years working with psy­chopaths and studying their thought processes— from the remorseless serial killers he meets with behind bars to children whose behavior and per­sonality traits exhibit the early warning signs of psychopathy. Less than 1 percent of the general population meets the criteria for psychopathy. But psycho­paths account for a vastly outsized proportion of violent crimes. And as Kiehl shows, many who aren’t psychopaths exhibit some of the behaviors and traits associated with the condition. What do you do if you discover your roommate, or boss, or the person you are dating has traits that define a psy­chopath? And what does having a diminished limbic region of the brain mean for how the legal system approaches crimes committed by psychopaths? A compelling narrative of cutting-edge science, The Psychopath Whisperer will open your eyes on a fascinating but little understood world, with startling implications for society, the law, and our personal lives.

    Our intellectual capacity, our introversion or extraversion, our vulnerability to mental illness, even whether we are a morning person - all of these aspects of our personality are profoundly shaped by our inherited DNA differences.In Blueprint, Robert Plomin, a pioneer in the field of behavioural genetics, draws on a lifetime's worth of research to make the case that DNA is the most important factor shaping who we are. Our families, schools and the environment around us are important, but they are not as influential as our genes. This is why, he argues, teachers and parents should accept children for who they are, rather than trying to mould them in certain directions. Even the environments we choose and the signal events that impact our lives, from divorce to addiction, are influenced by our genetic predispositions. Now, thanks to the DNA revolution, it is becoming possible to predict who we will become, at birth, from our DNA alone. As Plomin shows us, these developments have sweeping implications for how we think about parenting, education, and social mobility.A game-changing book by a leader in the field, Blueprint shows how the DNA present in the single cell with which we all begin our lives can impact our behaviour as adults.

    He’s a sociopath. And your boss, teacher, and colleague? They may be sociopaths too.We are accustomed to think of sociopaths as violent criminals, but in The Sociopath Next Door, Harvard psychologist Martha Stout reveals that a shocking 4 percent of ordinary people—one in twenty-five—has an often undetected mental disorder, the chief symptom of which is that that person possesses no conscience. He or she has no ability whatsoever to feel shame, guilt, or remorse. One in twenty-five everyday Americans, therefore, is secretly a sociopath. They could be your colleague, your neighbor, even family. And they can do literally anything at all and feel absolutely no guilt. How do we recognize the remorseless? One of their chief characteristics is a kind of glow or charisma that makes sociopaths more charming or interesting than the other people around them. They’re more spontaneous, more intense, more complex, or even sexier than everyone else, making them tricky to identify and leaving us easily seduced. Fundamentally, sociopaths are different because they cannot love. Sociopaths learn early on to show sham emotion, but underneath they are indifferent to others’ suffering. They live to dominate and thrill to win. The fact is, we all almost certainly know at least one or more sociopaths already. Part of the urgency in reading The Sociopath Next Door is the moment when we suddenly recognize that someone we know—someone we worked for, or were involved with, or voted for—is a sociopath. But what do we do with that knowledge? To arm us against the sociopath, Dr. Stout teaches us to question authority, suspect flattery, and beware the pity play. Above all, she writes, when a sociopath is beckoning, do not join the game. It is the ruthless versus the rest of us, and The Sociopath Next Door will show you how to recognize and defeat the devil you know.

    In The Ego Tunnel, philosopher Thomas Metzinger claims otherwise: No such thing as a self exists. The conscious self is the content of a model created by our brain—an internal image, but one we cannot experience as an image. Everything we experience is “a virtual self in a virtual reality.”But if the self is not “real,” why and how did it evolve? How does the brain construct it? Do we still have souls, free will, personal autonomy, or moral accountability? In a time when the science of cognition is becoming as controversial as evolution, The Ego Tunnel provides a stunningly original take on the mystery of the mind.

    How long should it take before you stop having to force it and start doing it automatically?The surprising answers are found in Making Habits, Breaking Habits, a psychologist's popular examination of one of the most powerful and under-appreciated processes in the mind. Although people like to think that they are in control, much of human behavior occurs without any decision-making or conscious thought.Drawing on hundreds of fascinating studies, psychologist Jeremy Dean busts the myths to finally explain why seemingly easy habits, like eating an apple a day, can be surprisingly difficult to form, and how to take charge of your brain's natural “autopilot” to make any change stick.Witty and intriguing, Making Habits, Breaking Habits shows how behavior is more than just a product of what you think. It is possible to bend your habits to your will—and be happier, more creative, and more productive.
