Ongoing Studies

Study 1

We are conducting a study to better understand children’s response to food cues they see in their everyday environment.

  • 9- 12 year olds
  • The study involves a total of 4 visits to our lab: 3 visits that are 1 week apart, and 1 visit a year later.
  • Visit 1 is about 2 hours, and visits 2-4 are about about 1.5 hours.
  • Your child will watch TV, play games, and eat foods (to participate, they must be ok with a meal of mac and cheese, applesauce, and corn and have no relevant food allergies or dietary restrictions).
  • The first visit includes an MRI brain scan while your child watches an age-appropriate TV show. The MRI is a safe and non-invasive procedure that is commonly used with children. It uses magnetic fields and does not involve radiation or contrast agents. If at any point your child didn't want to continue being scanned, we'd stop right away.
  • Your child will be asked to wear an activity monitor (like a fitbit) for 1 week between the first and second visits. They will be compensated an extra $20 for this.
  • Parents will be compensated $20 for completing questionnaires.
  • At the end of each study visit, your child will be compensated $55-$80for participating in all study components of the visit.
  • Appointments are available during lunch and dinner times on weekdays and weekends.

Study 2

  • 14-17 year olds
  • The study involves 1 lab visit that is up to 1.5 hours long.
  • Your child will watch film clips and ads for things like cars, clothes, food, and e-cigarettes. All clips and ads have been rated appropriate for children as young as 14 years old.
  • Your child will also complete computer tasks and answer a questionnaire.
  • We will measure what part of the screen your child is looking at using a camera.
  • The goal of the study is to understand how media exposure affects children’s beliefs about products. WE ASK THAT YOU DO NOT SHARE THE STUDY OBJECTIVES WITH YOUR CHILD, since doing so would impact the study’s scientific integrity. We will debrief your child once the study is completed.
  • You are welcome to accompany your child to the lab or s/he can attend alone.
  • Your child will be compensated $40for participating in the study.
  • Appointments are available on weekdays and weekends.

Study 3

  • 3-5 year olds
  • The study requires 5 days of assessments at home and 2 visits to our lab that will occur at the study start and then again 6 months later.

During the home-based assessments:

  • Your child will wear an activity monitor (like a fitbit; monitors movement and sleep) for 5 days and nights.
  • Your child will also wear an audio recording device for the first 2 days. The audio recording device is like a monitor to count the number of times your child talks during the day and the when s/he is exposed to digital media. The audio recording device does not save any raw audio files, and it is not possible for anyone on the study team to listen to the recordings.
  • We will be asked to keep a log of your child’s media and activity monitor use during this time.
  • We will mail the study materials to you, or you can visit our lab on the Dartmouth College campus to pick the material up.

During the lab visits:

  • Your child will play age-appropriate computer games.
  • Your child will be provided with snacks foods and water.
  • We will record your and your child’s weight and height.

Over the course of the study:

  • You will also complete four online surveys over the course of the study.
  • You and your child will be compensated a total of $170 for your time.
  • Appointments are available on weekdays and weekends.

Study 4

A study about how adolescents process different forms of electronic media:

  • 13-17 year olds
  • Involves 3 visits lasting 1-2 hours each
  • During each visit, your child will eat a meal, answer simple questions, and play some games on a computer, while having his/her eyes tracked using an eye tracker. The eye tracker is a camera that tracks where a person is looking on the screen. It is mounted on the computer and does not require any equipment to be placed on the head or around the eye.
  • Your child’s height and weight will be measured
  • Your child will be asked to wear an activity monitor (like a Fitbit) for several days between the first and second visits
  • Your child will receive $30 for the first visit, $40 for the second visit, and $70 for the third visit. (Also an additional $20 for wearing/returning activity monitor)
