Complex Syntax in the Language of Persons with Down Syndrome

This book examines the language abilities of persons with Down Syndrome who are able to read. The text defends the 'delayed but not deviant view' of linguistic abilities by examining a range of syntactic phenomena that develop at different points for typically developing children, and for which a similar overall pattern is found for persons with Down Syndrome. The volume also defends the 'delayed but not deviant view' against challenges arising from studies of the comprehension of definite pronouns. The study fits within a picture of linguistic abilities that is modular:  skills with language do not emerge from other cognitive functions.  It is an important source of information for readers in the departments of linguistics, speech and language therapy, and cognitive science.
