In a series of 14 chapters, this book brings together contemporary research findings on the involvement of word-internal structure for the purpose of word reading (especially morphological structure). Contributors include many leading experts in this research domain. The central theme of the book is approached from several angles, such that the chapters span a wide variety of topics where this issue is important. The experiments reported in the book involve: different populations; different languages; different processing levels where morphology may play a role; and different variables which may determine morphological effects. Given this scope, the book offers a state-of-the-art platform in psycholinguistic research on the topic.
