Abstract
This chapter presents a collection of hypothetical and novel mathematical models and formulas for language development and disorders. The author explores the potential and limitations of using mathematics to understand, measure, predict, and intervene in various aspects of language development and disorders, such as genetic, environmental, cognitive, linguistic, and social factors. The chapter consists of several parts. One part introduces the language development index (SLDI), a formula that measures the level of language development in children with or without developmental language disorders (DLD). Anotehr describes the hypothesis of language disorder inheritance, a formula that predicts the inheritance pattern based on genetic and environmental factors. The third section explains the linguistic complexity index for developmental language disorders and so on. The chapter concludes with a discussion of the advantages and disadvantages of using mathematical models and formulas in language development research and practice, as well as some suggestions for future directions.
