The D.E.N. is located in the Spence Labs of Psychology on The University of Iowa campus. The success of our research depends largely upon the participation of families like yours.  If you have a young child, you may be eligible to participate in one of our research projects. Your family's involvement will help us to gain valuable insight into how children develop. If you have a young child and are interested in participating, please see the details of each study below.

Preterm Birth Project

We are looking for families with:

  • At least one child between the ages of 3-5 years who was born at UIHC (term or preterm) or received neonatal care at UIHC. 

The child must:

  • Be a native speaker of English
  • Have normal or corrected-to-normal vision and hearing
  • Have no physical limitations that would prevent them from doing paper/pencil tasks
  • Have no history of a genetic syndrome, birth defect, or intellectual and developmental disability

Children taking stimulant medication must do a 24-48 hour wash-out prior to the visit.  Participation requires the child and the parent who is the primary caregiver complete a 3-hour visit at Spence Laboratory on the University of Iowa campus. The primary caregiver  will complete a diagnostic interview and questionnaires about their child. Children will complete neurocognitive testing. Parents and children may provide a saliva sample for future DNA analyses. Compensation and results from neurocognitive testing are provided. 

If interested, please go to to complete eligibility screening.
