Cognitive Styles and Learning Strategies [PDF ebook] 
Understanding Style Differences in Learning and Behavior

First Published in 1998. This book deals with what may well turn out to be the missing element in the study of individual differences – cognitive style. Its intention is to distinguish between, and integrate, the research attempts, particularly over the past half century, to make sense of style differences. In several respects this book is unique in that it contains material that is not covered in any other and draws together the various aspects of psychology relevant to the study of individual differences. It is in this sense both a textbook and a source of reference for many professionals working in a range of contexts. The content of the book has relevance for a wide audience.
