Children's Vocabulary Project
The Children's Vocabulary Project (2017-2022, McGregor PI)
Funding provided by the National Institutes of Health
The objective of this project is to discover how children's word learning changes over developmental time. The central hypothesis is that the challenge of word learning at different ages varies with the word-learning situation, the component of the word to be learned, and the development of underlying cognitive mechanisms. The project will test this hypothesis by tracking children in Iowa as they learn and retain new words over the course of one week during each of four years beginning in 1st grade.
The project involves two specific aims:
1) to establish a developmental trajectory of word learning in stronger and weaker learns that determines a) how learning and development vary with the learning situation and b) how learning and development vary with the component of the word to be learned
2) to specify the cognitive mechanisms underlying this developmental trajectory.
The expected contribution is a more nuanced and comprehensive understanding of word learning challenges and how these challenges change during a crucial developmental period. By addressing this issue, this project will offer new possibilities for tailoring preventive and therapeutic interventions in light of the child's developmental needs.
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:
- Children with typical language development
- Children who have had problems learning to talk or read but who do NOT have diagnosed Autism Spectrum Disorder, Hearing Impairment, or Intellectual Disability

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.
