This book presents the theory of threaded cognition, a theory that aims to explain the multitasking mind. The theory states that multitasking behavior can be expressed as cognitive threads-independent streams of thought that weave through the mind's processing resources to produce multitasking behavior, and sometimes experience conflicts to produce multitasking interference. Grounded in the ACT-R cognitive architecture, threaded cognition incorporates computational representations and mechanisms used to simulate and predict multitasking behavior and performance.

Multitasking is all around us: the office worker interrupted by a phone call, the teenager texting while driving, the salesperson chatting while entering an order. When multitasking, the mind juggles all the many tasks we're doing this second, this hour, this week, and tries to perform them together-sometimes with great ease, sometimes with great difficulty. We don't often stop to think about how exactly we accomplish these feats of multitasking great and small. How do we switch from one task to another? What types of multitasking are disruptive, and when are they most disruptive? And ultimately, how can we take advantage of the benefits of multitasking while alleviating its negative effects in our daily lives? This book presents the theory of threaded cognition, a theory that aims to explain the multitasking mind. The theory states that multitasking behavior can be expressed as cognitive threads-independent streams of thought that weave through the mind's processing resources to produce multitasking behavior, and sometimes experience conflicts to produce multitasking interference. Grounded in the ACT-R cognitive architecture, threaded cognition incorporates computational representations and mechanisms used to simulate and predict multitasking behavior and performance. The book describes the implications of threaded cognition theory across three traditionally disparate domains: concurrent multitasking (doing multiple tasks at once), sequential multitasking (interrupting and resuming tasks), and multitask skill acquisition (learning and practicing multiple tasks). The work stresses the importance of unifying basic and applied research by alternating between in-depth descriptions of basic research phenomena and broader treatments of phenomena in applied domains, such as driver distraction and human-computer interaction. The book also includes practical guidelines for designers of interactive systems intended for multitasking contexts.

A “brilliant and practical” study of why our brains aren’t built for media multitasking—and how we can learn to live with technology in a more balanced way (Jack Kornfield, author of The Wise Heart) Most of us will freely admit that we are obsessed with our devices. We pride ourselves on our ability to multitask—read work email, reply to a text, check Facebook, watch a video clip. Talk on the phone, send a text, drive a car. Enjoy family dinner with a glowing smartphone next to our plates. We can do it all, 24/7! Never mind the errors in the email, the near-miss on the road, and the unheard conversation at the table. In The Distracted Mind, Adam Gazzaley and Larry Rosen—a neuroscientist and a psychologist—explain why our brains aren't built for multitasking, and suggest better ways to live in a high-tech world without giving up our modern technology. The authors explain that our brains are limited in their ability to pay attention. We don't really multitask but rather switch rapidly between tasks. Distractions and interruptions, often technology-related—referred to by the authors as “interference”—collide with our goal-setting abilities. We want to finish this paper/spreadsheet/sentence, but our phone signals an incoming message and we drop everything. Even without an alert, we decide that we “must” check in on social media immediately. Gazzaley and Rosen offer practical strategies, backed by science, to fight distraction. We can change our brains with meditation, video games, and physical exercise; we can change our behavior by planning our accessibility and recognizing our anxiety about being out of touch even briefly. They don't suggest that we give up our devices, but that we use them in a more balanced way.

"A fresh take on the problem of time wasters in our corporate and personal lives, "The Myth of Multitasking" will change your paradigm about what is productive and what is not."--Hyrum Smith, co-founder, Franklin Covey.

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.

Multitasking Doesn’t Work —Learn What Does! “...multitasking is, in fact, a lie that actually wastes time, energy, and money. Most of all, it robs us of life and our relationships with others.” —Chuck Norris, world-renowned actor and martial artist Through anecdotal and real-world examples, The Myth of Multitasking proves that multitasking hurts your focus and productivity. Instead, learn how to be more effective by doing one thing at a time. Productivity and effective time management end with multitasking. The false idea that multitasking is productive has become even more prevalent and damaging to our productivity and well-being since the first edition of The Myth of Multitasking was published in 2008. In this revised and updated second edition, author and productivity expert Dave Crenshaw provides a solution for the chaos of distraction that multitasking creates —and a way to combat the temptation to constantly switch between tasks. Learn how to actually get things done. Dave Crenshaw takes the idea of multitasking as a productivity tool and smashes it to smithereens. But rather than leaving you with the burden of wading through the wreckage all by yourself, he shows you how to focus, move forward, and free up more time for what you value the most. In this new edition of The Myth of Multitasking, discover: Updated research on how and why multitasking doesn’t work Worksheets to help you figure out how to manage your day effectively Easy, actionable steps to manage your life well and accomplish your dreams and goals Readers of self-improvement books and time management books like Indistractable, Free to Focus, or It Doesn't Have to Be Crazy at Work will love increasing productivity and personal success with The Myth of Multitasking.

The thirty-two contributions discuss evidence from psychological experiments with healthy and brain-damaged subjects, functional imaging, electrophysiology, and computational modeling.
