Word Learning Laboratory

The Word Learning Lab aims to understand: how people learn new words, how knowledge of word meanings deepens over time, and how to facilitate rich vocabulary learning among children who are challenged by language learning impairments.

The Children’s Vocabulary Project

​​​Enroll your child in a research study that ​will ​help us determine how vocabulary-learning skills change as children grow.

What is the Purpose of Our Study?

To aid in the development of programs and therapies that facilitate vocabulary growth in children.

Who Should Participate?

  • 6- to 7-year-old children in Iowa:
    • Who are in first grade or in the summer between first and second grade
    • Who speak English only (not bilingual)
  • We are recruiting:

What Does Participation Require?

Participation includes language testing and computer tasks, all designed to be enjoyable for children. Testing results are shared with parents. Children will meet with the research team over the course of the 4 year study.

  • One qualification visit to determine if your child's language profile meets study specifications
  • 3 visits per year for 4 years. These visits will be scheduled during roughly the same two-week period every year.
  • Each visit will last 1-2 hours and will involve brief computer tasks and language testing. All tasks are designed to be engaging for children and participants will be given adequate breaks.

Where Will Testing Take Place?

Researchers come to you! Our testing van will meet you at your home or another preferred local site (e.g., library parking lot, community center). Visits are flexible and will be scheduled to fit your family's availability.

Will I be Compensated for My Time?

Yes! Your child will be compensated at the rate of $20 per hour for all visits with a probable compensation of $75 per year and a total likely compensation of $300 over the four years.

Can I Keep My Child's Testing Results?

Children's scores on all language testing will be shared with parents. ​A licensed Speech-Language Pathologist will be available to answer questions and provide feedback regarding your child's language abilities. ​
