Word Learning From Parentese in Autistic Children Study

This study is looking at how autistic children learn new words. Researchers want to see if "parentese speech" (a way adults often talk to babies with higher pitch and longer sounds) helps autistic children learn words better than "adult registered speech" (normal adult talking). They will show children new words using both types of speech. The study will measure how long children look at the correct object when a new word is introduced. This study is for children with or without an autism diagnosis, between 18 months and 59 months old. The study is currently unclear about its status and plans to enroll 100 children.

What this trial measures

  • Proportion of time during which children's eye gaze is directed toward the target object300 ms after the target words are introduced

    Children's eye gaze is recorded as they look at images. The proportion of time during which gaze is directed to an image of the targeted word is the dependent measure.
