Book excerpt: Spelling and Writing Words: Theoretical and Methodological Advances provides a set of contributions about how individuals write words. Understanding word production is of major importance as it allows understanding how words -the basic elements of written language- are stored in the writers’ brain and how do writers select the spelling of a word. “br/> The theoretical chapters address hot topics in the field such as the role of phonology in writing, bilingualism, language disorders, orthographic acquisition, and the influence of handwriting on reading. The methodological chapters address individual differences, how to measure handwriting performance in different handwriting styles, and neuroscientific approaches. The concluding chapters explore the future of written word production research.
