Down Syndrome is defined as a genetic disorder that is caused by abnormal cell division that results in an extra full or partial copy of chromosome 21. Children with Down Syndrome (DS) experience delays in all areas of development; however, they have specific deficits in developing expressive language acquisition. This review explores the effect of both play and joint attention on expressive language development. It also discusses the effect of Naturalistic Sign Intervention. The LENA (Language Environment Analysis) was used to explore the effect of behavioral phenotypes on expressive language development.
