For Parents and Participants

Dr. Brannon & Julian Park

In the Brannon Lab we study the development of numerical cognition across the lifespan. We conduct behavioral and neuroimaging studies with infants, kids and adults. In this way, we hope to learn how our understanding of number changes throughout development and to discover the biological bases of this understanding.

FAQ’s

Where can we find you?

Click here for directions.

Where can I park?

Upon your arrival, we will provide you with a parking pass for a lot near our building.

How do you find participants?

We get babies’ names from the public birth records of Durham, Orange and Wake Counties. We then look up phone numbers and store the information in our secure database. You have the option of having your name removed from the database at any time.

How long does a visit take?

Visits last anywhere from 30 minutes to two hours, depending on study type. This allows time for parking, doing some paperwork and for you and your child to get comfortable in the lab prior to beginning the study.

What happens during the visit?

After filling out some initial paperwork, you will have the opportunity to ask questions of the experimenter. What happens next depends on the type of study with which your children are involved.

For behavioral studies with infants, your baby will sit on your lap or in a high chair right next to you. We will show him/her some pictures on a computer screen in front of them. We record how long your baby looks at these pictures in order to understand what babies know about things like number and time.

For ERP studies with infants, after filling out some initial paperwork, you will have the opportunity to ask questions of the researcher. When you and your baby are comfortable, your baby will sit on your lap or in a high chair next to you and view pictures on a computer screen or a puppet show. They will wear a stretchy cap that contains small sensors that record your baby’s brain activity. The study can be stopped at any point if your baby is uncomfortable.

For behavioral studies with kids, your child will play a series of games. Some involve using a touch screen computer; others will be table-games played with the experimenter. Throughout the games, your child will be rewarded with stickers or tokens. They will also receive a larger toy at the end.

For ERP studies with kids, your child will sit in a chair and play an iPad game while experimenters place a stretchy cap on his or her head and fill it with gel. This cap contains small sensors which will read your child’s brain activity while he or she plays a simple computer game. Your child will be rewarded with a small snack and with stickers, and can choose a larger toy at the end.

For fMRI studies with kids, during the first 30 minutes of your visit, you and your child will be introduced to the procedure using a mock MRI Scanner. The mock scanner is designed to familiarize children with the sights and sounds of a real MRI scan. During this time parents will complete some paperwork and will have the opportunity to ask questions of the experimenter. After the training session, we will continue onto the real MRI scanner. Parents can watch from an observation room while an experimenter accompanies your child into the scanner. Your child will be given ear plugs, headphones, and a microphone so that they will be able to communicate with the experimenters and the MRI technician at all times. During the MRI Scan your child will watch a movie and play a few computer games. If at any point you or your child do not want to continue with the experiment we will stop immediately.

Will you be able to provide me with information about my child’s performance?

We are primarily interested in average performance across many children in a given age group. We will not be able to provide you with an individual evaluation of your child.

What if my child becomes uncomfortable?

Generally, babies find the study to be fun and entertaining. However, if your child becomes uncomfortable or fussy, we can take a break or stop the study at any point.

Does my child have to visit more than once?

Some studies involve more than one visit, but many do not. We will be sure to discuss this with you when we schedule your appointment!

What do my child and I receive for participating?

For behavioral studies with infants, your baby will receive a small gift (usually a t-shirt or bib) as well as an Infant Scientist Degree. We also offer parents $5 for travel reimbursement.
For ERP studies with infants, your baby will receive a small gift (usually a t-shirt or bib) as well as an Infant Scientist Degree and a picture of their brain waves. We also offer parents $10 for travel reimbursement.
For behavioral studies with kids, your child may choose a small gift and some stickers. We also offer parents $5 for travel reimbursement.
For fMRI studies with kids, your child will receive a small toy after the completing the mock MRI scanner training and a larger toy after completing the real MRI scanner. We also offer $25 per hour and pictures of your child’s brain.

Can I bring my other children along?

Of course. We have many toys and books in our waiting room and a member of our friendly staff will stay with your other children while you are with your child.

What do you do with the results of your study?

Many of our studies are published in academic journals or presented at conferences. All data is presented in the form of group statistics and your child’s name or personal information will never be published or connected with their data.
