Cognitive flexibility is the cornerstone of learning and enables us to cope with a constantly changing environment. By adapting our knowledge and habits in order to respond to new situations, cognitive flexibility plays a fundamental role in learning. This book proposes a study of the fundamental notions of cognitive flexibility: its measurement and development, its links with metacognition and critical thinking and the role of context in its expression, as well as its involvement in discovering solutions, transferring knowledge and processing analogies. Convergent perspectives are also presented in order to paint a clear picture of cognitive flexibility and to discuss the issues at stake. Thanks to the combined views of specialists in cognitive and developmental psychology, Cognitive Flexibility suggests new educational possibilities based on the results of empirical work on the subject.
