According to the CDC autism spectrum disorder affects 1 in 150 children. The Language Use Inventory (LUI) is a questionnaire for parents about their child's language use in various settings. It focuses on pragmatic language development in everyday interactions. This will help doctors understand ways of identifying language skills in autistic children.

14 children with autism spectrum disorder participated in the "Hunter Heartbeat Method" which is a drama-based social skills intervention. The children play games that work on skills like facial emotion recognition, personal space, social improvisation, and pragmatics of dialogue exchange. The games are based on the plot of The Tempest and are taught in a relaxed and playful environment. At the end of the ten week program, children showed better language skills and were able to better recognize facial expressions.

A study done with monolingual babies and bilingual babies under a year old showed that in the earlier months, both sets of babies had discrimination abilities to separate languages, but by eight months only the bilinguals had this ability. The study was done by only showing visual clips of people speaking different languages. This means that the babies could differentiate languages by looking at facial movements and the rhythm and shape of the person's mouth.

In a study, it is predicted that bilinguals have enhanced brain networks because they had a delayed onset of Alzheimer's by five years compared to monolinguals of similar educational backgrounds. Through CT scans, it was discovered that bilinguals physically had twice as much atrophy of the brain as monolinguals at the time symptoms started. This means that bilinguals showed no symptoms of Alzheimer's even though their brains physically looked like they did.
