Research on implicit learning - a cognitive phenomenon in which people acquire knowledge without conscious intent or awareness - has been growing exponentially. This volume draws together this research, offering the first complete reference on implicit learning by those who have been instrumental in shaping the field. The contributors explore controversies in the field, and examine: functional characteristics, brain mechanisms and neurological foundations of implicit learning; connectionist models; and applications of implicit learning to acquiring new mental skills.

Attention and Implicit Learning provides a comprehensive overview of the research conducted in this area. The book is conceived as a multidisciplinary forum of discussion on the question of whether implicit learning may be depicted as a process that runs independently of attention. The volume also deals with the complementary question of whether implicit learning affects the dynamics of attention, and it addresses these questions from perspectives that range from functional to neuroscientific and computational approaches. The view of implicit learning that arises from these pages is not that of a mysterious faculty, but rather that of an elementary ability of the cognitive systems to extract the structure of their environment as it appears directly through experience, and regardless of any intention to do so. Implicit learning, thus, is taken to be a process that may shape not only our behavior, but also our representations of the world, our attentional functions, and even our conscious experience.

Implicit learning is said to occur when a person learns about a complex stimulus without necessarily intending to do so, and in such a way that the resulting knowledge is difficult to express. Over the last 30 years, a number of studies have claimed to show evidence of implicit learning. In more recent years, however, considerable debate has arisen over the extent to which cognitive tasks can in fact be learned implicitly. Much of the debate has centred on the questions of how unconscious, and how abstract, is implicitly acquired knowledge? The aim of this book is to provide students and researchers with a self-contained and balanced summary of the various theoretical and empirical positions that are currently shaping this exciting area of research.

Can you learn without knowing it? This controversial and much debated question forms the basis of this collection of essays as the authors discuss whether the measurable changes in behaviour that result from learning can ever remain entirely unconscious. Three issues central to the topic of implicit learning are raised. Firstly, the extent to which learning can be unconscious, and therefore implicit, is considered. Secondly, theories are developed regarding the nature of knowledge acquired in implicit learning situations. Finally, the idea that there are two separable independent processing systems in the brain, for implicit and explicit learning, is considered. Implicit Learning and Consciousness challenges conventional wisdom and presents the most up-to-date studies to define, quantify and test the predictions of the main models of implicit learning. The chapters include a variety of research from computer modelling, experimental psychology and neural imaging to the clinical data resulting from work with amnesics. The result is a topical book that provides an overview of the debate on implicit learning, and the various philosophical, psychological and neurological frameworks in which it can be placed. It will be of interest to undergraduates, postgraduates and the philosophical, psychological and modeling research community.

There is considerable debate over the extent to which cognitive tasks can be learned non-consciously or implicitly. In recent years a large number of studies have demonstrated a discrepancy between explicit knowledge and measured performance. This book presents an overview of these studies and attempts to clarify apparently disparate results by placing them in a coherent theoretical framework. It draws on evidence from neuropsychological and computational modelling studies as well as the many laboratory experiments. Chapter one sets out the background to the large number of recent studies on implicit learning. It discusses research on implicit memory, perception without awareness, and automaticity. It attempts to set the implicit - explicit distinction in the context of other relevant dichotomies in the literature. Chapter two presents an overview of research on the control of complex systems, from Broadbent (1977) through to the present day. It looks at the accessibility of control task knowledge, as well as whether there is any other evidence for a distinction between implicit and explicit modes of learning. Chapter three critically reviews studies claiming to show that people can acquire concepts without being verbally aware of the basis on which they are responding. It shows that concept formation can be implicit in some sense but not in others. Chapter four investigates the claim that people can learn sequential information in an implicit way. Chapter five looks at whether computational modelling can elucidate the nature of implicit learning. It examines the feasibility of different exemplar connectionist models in accounting for performance in concept learning, sequence learning, and control task experiments. Chapter six reviews evidence concerning dissociations between implicit and explicit knowledge in various neuropsychological syndromes. Finally, chapters seven and eight discuss the many practical and theoretical implications of the research.

Can we learn without knowing we are learning? To what extent is our behavior influenced by things we fail to perceive? What is the relationship between conscious and unconscious cognition? Implicit Learning: 50 Years On tackles these key questions, fifty years after the publication of Arthur Reber’s seminal text. Providing an overview of recent developments in the field, the volume considers questions about the computational foundations of learning, alongside phenomena including conditioning, memory formation and consolidation, associative learning, cognitive development, and language learning. Featuring contributions from international researchers, the book uniquely integrates ‘Western’ thinking on implicit learning with insights from a rich Russian research tradition. This approach offers an excellent opportunity to contrast perspectives, to introduce new experimental paradigms, and to contribute to ongoing debates about the very nature of implicit learning. Implicit Learning: 50 Years On is essential reading for students and researchers of consciousness, specifically those interested in implicit learning.
