Abstract

The Conclusion summarizes the book's main arguments. This book has argued that, conceptual change is an essential component of scientific progress but what is known about the psychology of concepts needs to be organized in a coherent framework. The Conclusion contends that current theories fail to explain all the known phenomena. The book has sketched a framework for developing multi-process theories of the higher cognitive competences, identifying several key questions that need to be answered by proponents of these theories.
