Brain Imaging, eye Tracking, and Eating Study (BITES)

We are looking for 44 children between the ages of 7-10 years to visit our lab and find out why and how TV commercials make people feel hungry. The study visit lasts about 2 hours. During the 2 hours, your child will be served a dinner meal and then they will watch children's television program with commercials during a brain scan with an MRI (no radiation). Afterwards, we will ask your child about the commercials they saw. Snacks and toys will be provided at the end of the visit.
