Book Description
In reading, word frequency is commonly regarded as the major bottom-up determinant for the speed of lexical access. Moreover, language processing depends on top-down information, such as the predictability of a word from a previous context. Yet, however, the exact role of top-down predictions in visual word recognition is poorly understood: They may rapidly affect lexical processes, or alternatively, influence only late post-lexical stages. To add evidence about the nature of top-down processes and their relation to bottom-up information in the timeline of word recognition, we examined influences of frequency and predictability on event-related potentials (ERPs) in several sentence reading studies. The results were related to eye movements from natural reading as well as to models of word recognition. As a first and major finding, interactions of frequency and predictability on ERP amplitudes consistently revealed top-down influences on lexical levels of word processing (Chapters 2 and 4). Second, frequency and predictability mediated relations between N400 amplitudes and fixation durations, pointing to their sensitivity to a common stage of word recognition; further, larger N400 amplitudes entailed longer fixation durations on the next word, a result providing evidence for ongoing processing beyond a fixation (Chapter 3). Third, influences of presentation rate on ERP frequency and predictability effects demonstrated that the time available for word processing critically co-determines the course of bottom-up and top-down influences (Chapter 4). Fourth, at a near-normal reading speed, an early predictability effect suggested the rapid comparison of top-down hypotheses with the actual visual input (Chapter 5). The present results are compatible with interactive models of word recognition assuming that early lexical processes depend on the concerted impact of bottom-up and top-down information. We offered a framework that reconciles the findings on a timeline of word recognition taking into account influences of frequency, predictability, and presentation rate (Chapter 4).

Book Description
Originally published in 1992. This book brings together the work of a number of distinguished international researchers engaged in basic research on beginning reading. Individual chapters address various processes and problems in learning to read - including how acquisition gets underway, the contribution of story listening experiences, what is involved in learning to read words, and how readers represent information about written words in memory. In addition, the chapter contributors consider how phonological, onset-rime, and syntactic awareness contribute to reading acquisition, how learning to spell is involved, how reading ability can be explained as a combination of decoding skill plus listening comprehension skill, and what causes reading difficulties and how to study these causes.

Book Description
A surprising take on how you can help tackle the really big problems in society–from one of America’s most successful entrepreneurs. People are looking for a better way. Towering barriers are holding millions of people back, and the institutions that should help everyone rise are not doing the job. Crumbling communities. One-size fits all education. Businesses that rig the economy. Public policy that stifles opportunity and emboldens the extremes. As a result, this country is quickly heading toward a two-tiered society. Today’s challenges call for nothing short of a paradigm shift – away from a top-down approach that sees people as problems to be managed, toward bottom-up solutions that empower everyone to realize their potential and foster a more inclusive society. Such a shift starts by asking: What would it mean to truly believe in people? Businessman and philanthropist Charles Koch has devoted his life to answering that question. Learn what he’s discovered during his 60-year career to help you apply the principles of empowerment in your life, in your business, and in society. By learning from the social movements and applying the principles that have enabled social progress throughout history, Koch has achieved more than he dreamed possible – building one of the world’s most successful companies and founding Stand Together, one of America’s most innovative philanthropic communities. Stand Together CEO Brian Hooks and Koch show how the only way to solve the really big problems – from poverty and addiction to harmful business practices and destructive public policy – is for each and every one of us to find and take action in our unique role as part of the solution. Full of compelling examples of what works – including several first-person accounts from individuals whose lives have been transformed – Koch and Hooks’ refreshing approach promotes partnership instead of partisanship and speaks to people from different perspectives and all walks of life. They show that no injustice is too tough to overcome if you share a deep belief in people, are willing to unite with anyone to do right, and work to empower others from the bottom up.

Book Description
Bottom-up is a way of life and a way of doing business. The Bottom-Up Revolution picks up where Malcolm Gladwell's Tipping Point left off, describing an emerging cultural phenomenon with deep biological and evolutionary underpinnings. It is a how-to book for businesses, leaders, organizations, activists, and individuals, cracking wide-open humankind's biggest trend in seven million years. By understanding the roots and implications of "bottom up" and "top down" you'll be better able to tap the incredible power of this trend, as the billionaire founders of Craigslist, Google, Facebook, and Twitter, and political revolutionaries have done. It includes interview excerpts with Twitter founder Jack Dorsey, Craigslist founder Craig Newmark, Fritjof Capra, Frans de Waal, Ann Marie Slaughter, Joseph Nye, Naomi Klein, Nicholas Carr, Riane Eisler, George Lakoff, Douglas Rushkoff, Robin Chase, Darcia Narvaez, Dennis Kucinich, Tim O'Reilly, Mike Medavoy, and John McKnight. Why you need this book? You can learn: to unleash the bottom-up powers brimming within you to apply bottom-up ideas to make your organization more successful to connect better and how connection and disconnection have changed how top-down thinking and values have enabled an authoritarian explosion to have more, better, deeper positive experiences how and why to have hero's journeys how bottom-up is a core progressive value how some of the most successful business pioneers have tapped the power of bottom-up to tap new, revolutionary ways to manage to use bottom-up thinking and ways to more effectively use social media and search engines to use bottom-up approaches to build more effective, smarter, successful websites build and access power-political, personal, community, organizational-that was not available in the top-down world, before the bottom-up revolution to run effective, successful crowdsourcing campaigns how to get yourself or your organization a Wikipedia page why bottom-up is one of the most disruptive forces in the world to think about creating new products and business that tap into our bottom-up genetic evolutionary wiring how bottom-up thinking is a core part of making activism work, making your visions for change a reality. to understand how bottom-up will change your life, world, and relationships how story plays an essential bottom-up role in changing yourself and the world to see the world through bottom-up eyes, with more caring, compassion, and understanding of how culture and society work

Book Description
Research on discourse (or text) processing has only recently come into its own. It builds on the work of text analysis which has a long and distinguished history, but modern developments in psychology (e.g. memory research), artificial intelligence, linguistics and philosophy have contributed to this emergence in the last decade as a lively and promising research area.This book contains 46 selected and edited contributions from the International Symposium held in Fribourg in 1981, and represents a truly international overview of the developments in research on written and oral discourse. The contributions have been grouped according to problem area and not according to methodology, with the intention of focusing on the important issues in the field of discourse processing and of showing how diverse approaches contribute to a better understanding of the problems involved. The main themes are: text structure, coherence, inference, memory processes, attention and control, goal perspectives, and educational implications.
