Frequently Ask Questions


Dear Parents,

The Cognitive Development Lab at Indiana State University is conducting a study on the development of counting in infants.  We know that infants cannot count yet, but we are interested in whether they are starting to understand the basics of counting.  For example, can they tell the difference between a correct counting sequence and an incorrect counting sequence.  Through this study, we are trying to understand how kids learn to count and how this important skill develops from an early age.  We are requesting your help in this project.

Your participation would involve bringing your infant to our laboratory for one brief visit.   The visit should take no longer than 45 minutes.  The actual testing of your infant will only take about 5 minutes, but we need extra time to explain the study, fill out paperwork, get set up, etc.  When you arrive, we will thoroughly explain the nature of our research and this specific project.  You will be asked to complete a brief questionnaire about your infant.  Next, your infant will be placed in a car seat and electrodes will be placed on his/her chest to record your infant’s heart rate during the study.  We will show your baby two videos of correct and incorrect counting.  In addition to recording your infant’s heart rate, we will also be recording how long your infant looks at the videos.  You will be with your child at all times.  We also offer toys and space to bring other siblings, if needed.  Please remember that your participation in this project is voluntary and that all of the information we collect will be kept strictly confidential.

We invite you to contact us at our lab by e-mail at or by phone (812) 237-4936, if you are interested in learning more about this study. We would be happy to explain the study further or schedule an appointment for you and your child to participate in this project.  The Cognitive Development Laboratory is located in Room B-020, in Root Hall, at 450 North Seventh Street.  Parking is provided outside of our laboratory.  We can provide you with a more detailed map and directions to our lab, if needed.

We hope that you will be able to help us in this research project, and we certainly would be grateful for your assistance.  Your participation will help contribute to the growing knowledge about how children learn, think, and develop.
