Writing is central to the functioning of developed societies. However, the psychological processes that allow us to transform complex ideas into language and express them on paper or computer screen are poorly understood. Writing and Cognition goes some way towards remedying this. It describes new and diverse work both by field leaders and by newer researchers exploring the complex relationships between language, the mind, and the environments in which writers work. Chapters range in focus from a detailed analysis of single-word production to the writing of whole texts. They explore the basic processes involved in writing, the effects of writing on thought and how these vary across different educational and workplace contexts.
