Summary

This trial explores if deaf children learning sign language assume each object has one word ("mutual exclusivity"). It also explores if those learning both sign & spoken language demonstrate the same behavior.

Who is the study for?

This trial is for deaf children aged 18-60 months who were born with severe to profound hearing loss. It's suitable for those who use American Sign Language (ASL) and have normal or corrected-to-normal vision, regardless of whether their parents are deaf or hearing.

What is being tested?

The study investigates how deaf children learn words using a principle called mutual exclusivity - the idea that each object has only one name. Researchers will see if this applies to kids learning ASL and those learning both ASL and spoken language through eye-tracking and behavior observation.

What are the potential side effects?

Since this study involves observational methods like eye-tracking rather than medical interventions, there are no direct side effects associated with it. However, participation may involve typical discomforts from wearing eye-tracking equipment.
