On 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.

This comprehensive, forward-looking text is the first holistic research overview and practical methods guide for researching the role that affective and conative factors play in second language learners’ task performance and language acquisition. It provides a long overdue update on the role of the learner in task-based language teaching (TBLT). The book brings together theoretical background and major constructs, established and innovative methodological and technological tools, cutting-edge findings, and illuminating suggestions for future work. A group of expert scholars from around the world synthesize the state of the art, detail how to design and conduct empirical studies, and authoritatively set the agenda for future work in this critical, emerging area of language learning and instructional design. With a variety of helpful features like suggested research, discussion questions, and recommended further readings, this will be an invaluable resource to advanced students and researchers of second language acquisition, applied linguistics, psychology, education, and related areas.

This volume extends the Task-Based Language Teaching: Issues, Research and Practice books series by deliberately exploring the potential of task-based language teaching (TBLT) in a range of EFL contexts. It is specifically devoted to providing empirical accounts about how TBLT practice is being developed and researched in diverse educational contexts, particularly where English is not the dominant language. By including contributions from settings as varied as Japan, China, Korea, Venezuela, Turkey, Spain, and France, this collection of 13 studies provides strong indications that the research and implementation of TBLT in EFL settings is both on the rise and interestingly diverse, not least because it must respond to the distinct contexts, constraints, and possibilities of foreign language learning. The book will be of interest to SLA researchers and students in applied linguistics and TESOL. It will also be of value to course designers and language teachers who come from a broad range of formal and informal educational settings encompassing a wide range of ages and types of language learners.

One thing that separates human beings from the rest of the animal world is our ability to control behavior by referencing internal plans, goals, and rules. This ability, which is crucial to our success in a complex social environment, depends on the purposeful generation of "task sets"--states of mental readiness that allow each of us to engage with the world in a particular way or achieve a particular aim. This book reports the latest research regarding the activation, maintenance, and suppression of task sets. Chapters from many of the world's leading researchers in task switching and cognitive control investigate key issues in the field, from how we select the most relevant task when presented with distracting alternatives, to how we maintain focus on a task ("eyes on the prize") and switch to a new one when our goals or external circumstances change. Chapters also explore the brain structures responsible for these abilities, how they develop during childhood, and whether they decline due to normal aging or neurological disorders. Of interest especially to scholars and students of cognitive psychology, the volume offers thorough, multi-disciplinary coverage of contemporary research and theories concerning this fundamental yet mysterious aspect of human brain function and behavior.

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.

Over the last decade task-based approaches to language learning and teaching (TBLT) have become a global focus of increased levels of research. Governments around the world have turned to TBLT as a potential solution for curricula that lack authentic and meaningful engagement with language learning and are failing to motivate students as a result. This book focuses on Asia, where this shift has been particularly in evidence. TBLT has often been implemented in top-down approaches to curriculum development, which presents a huge range of challenges at the cultural as well as the pedagogic level. Contemporary Task Based Language Teaching in Asia looks at the drivers, stakeholders and obstacles across the region. Some countries have adapted TBLT to deal with the local constraints, others have found it hard to apply and many are still in the process of investigating its implementation in their specific contexts. This collection is important to all involved in language development, from curriculum reform to materials development. It assists from programme evaluation to the setting of assessment standards. The chapters cover all aspects of language education across Asia, from primary to tertiary, private and public education, as well as innovations at local, regional and national levels.

Experts from a range of disciplines explore how humans and artificial agents can quickly learn completely new tasks through natural interactions with each other. Humans are not limited to a fixed set of innate or preprogrammed tasks. We learn quickly through language and other forms of natural interaction, and we improve our performance and teach others what we have learned. Understanding the mechanisms that underlie the acquisition of new tasks through natural interaction is an ongoing challenge. Advances in artificial intelligence, cognitive science, and robotics are leading us to future systems with human-like capabilities. A huge gap exists, however, between the highly specialized niche capabilities of current machine learning systems and the generality, flexibility, and in situ robustness of human instruction and learning. Drawing on expertise from multiple disciplines, this Strüngmann Forum Report explores how humans and artificial agents can quickly learn completely new tasks through natural interactions with each other. The contributors consider functional knowledge requirements, the ontology of interactive task learning, and the representation of task knowledge at multiple levels of abstraction. They explore natural forms of interactions among humans as well as the use of interaction to teach robots and software agents new tasks in complex, dynamic environments. They discuss research challenges and opportunities, including ethical considerations, and make proposals to further understanding of interactive task learning and create new capabilities in assistive robotics, healthcare, education, training, and gaming.
