Our Task

A look at the extraordinary ways the brain turns thoughts into actions—and how this shapes our everyday lives Why is it hard to text and drive at the same time? How do you resist eating that extra piece of cake? Why does staring at a tax form feel mentally exhausting? Why can your child expertly fix the computer and yet still forget to put on a coat? From making a cup of coffee to buying a house to changing the world around them, humans are uniquely able to execute necessary actions. How do we do it? Or in other words, how do our brains get things done? In On Task, cognitive neuroscientist David Badre presents the first authoritative introduction to the neuroscience of cognitive control—the remarkable ways that our brains devise sophisticated actions to achieve our goals. We barely notice this routine part of our lives. Yet, cognitive control, also known as executive function, is an astonishing phenomenon that has a profound impact on our well-being. Drawing on cutting-edge research, vivid clinical case studies, and examples from daily life, Badre sheds light on the evolution and inner workings of cognitive control. He examines issues from multitasking and willpower to habitual errors and bad decision making, as well as what happens as our brains develop in childhood and change as we age—and what happens when cognitive control breaks down. Ultimately, Badre shows that cognitive control affects just about everything we do. A revelatory look at how billions of neurons collectively translate abstract ideas into concrete plans, On Task offers an eye-opening investigation into the brain’s critical role in human behavior.

ÊThis book describes the common task which Balthasar and Adrienne von Speyr undertook, the founding of a secular institute: The Community of St. John. He also describes their common theological work and explains the theology and role of secular institutes. Ê

"General McChrystal is a legendary warrior with a fine eye for enduring lessons about leadership, courage, and consequence." —Tom Brokaw General Stanley McChrystal is widely admired for his hunger to know the truth, his courage to find it, and his humility to listen to those around him. Even as the commanding officer of all U.S. and coalition forces in Afghanistan, he stationed himself forward and frequently went on patrols with his troops to experience their challenges firsthand. In this illuminating New York Times bestseller, McChrystal frankly explores the major episodes and controversies of his career. He describes the many outstanding leaders he served with and the handful of bad leaders he learned not to emulate. And he paints a vivid portrait of how the military establishment turned itself, in one generation, into the adaptive, resilient force that would soon be tested in Iraq, Afghanistan, and the wider War on Terror. "A compelling account of his impressive career." -The Wall Street Journal ' "This is a brilliant book about leadership wrapped inside a fascinating personal narrative." -Walter Isaacson, author of Steve Jobs Stanley McChrystal retired in July 2010 as a four-star general in the U.S. Army. His last assignment was as the commander of the International Security Assistance Force and as the commander of U.S. forces in Afghanistan. He is currently a senior fellow at Yale University's Jackson Institute for Global Affairs and cofounder of the McChrystal Group, a leadership consulting firm. He and his wife, Annie, live in Virginia.

“This is a book about nature and culture,” Eric T. Freyfogle writes, “about our place and plight on earth, and the nagging challenges we face in living on it in ways that might endure.” Challenges, he says, we are clearly failing to meet. Harking back to a key phrase from the essays of eminent American conservationist Aldo Leopold, Our Oldest Task spins together lessons from history and philosophy, the life sciences and politics, economics and cultural studies in a personal, erudite quest to understand how we might live on—and in accord with—the land. Passionate and pragmatic, extraordinarily well read and eloquent, Freyfogle details a host of forces that have produced our self-defeating ethos of human exceptionalism. It is this outlook, he argues, not a lack of scientific knowledge or inadequate technology, that is the primary cause of our ecological predicament. Seeking to comprehend both the multifaceted complexity of contemporary environmental problems and the zeitgeist as it unfolds, Freyfogle explores such diverse topics as morality, the nature of reality (and the reality of nature), animal welfare, social justice movements, and market politics. The result is a learned and inspiring rallying cry to achieve balance, a call to use our knowledge to more accurately identify the dividing line between living in and on the world and destruction. “To use nature,” Freyfogle writes, “but not to abuse it.”

Multitasking refers to performance of multiple tasks. The most prominent types of multitasking are situations including either temporal overlap of the execution of multiple tasks (i.e., dual tasking) or executing multiple tasks in varying sequences (i.e., task switching). In the literature, numerous attempts have aimed at theorizing about the specific characteristics of executive functions that control interference between simultaneously and/or sequentially active component of task-sets in these situations. However, these approaches have been rather vague regarding explanatory concepts (e.g., task-set inhibition, preparation, shielding, capacity limitation), widely lacking theories on detailed mechanisms and/ or empirical evidence for specific subcomponents. The present research topic aims at providing a selection of contributions on the details of executive functioning in dual-task and task switching situations. The contributions specify these executive functions by focusing on (1) fractionating assumed mechanisms into constituent subcomponents, (2) their variations by age or in clinical subpopulations, and/ or (3) their plasticity as a response to practice and training.
