Eligibility Questions: 

Q: How old do I need to be to participate in this study? 
We are looking for teenagers between 13 and 16 years of age. 

Q: How do I find out if I am eligible?
If you are interested in our study, we will arrange a time to do a brief phone interview with you and a parent. During this interview, we will explain our study, answer any questions you might have, and determine whether you are eligible to participate. 

General Study Information: 

Q: How many times do I have to come to the lab? 
If you are eligible to participate, you will be asked to come to the lab four times over the next two years as well as complete four short online surveys. The first and second visits occur within one week of each other. The third and fourth visits will follow one and two years afterwards. 

Q: Where is the lab located?
The lab is located in Ann Arbor.

Q: How long is each visit and how will I get paid? 
Our visits are paid by the hour according to typical behavioral and neurological study rates. Overall, you will have the opportunity to earn up to $150. Specifically, Visit 1 is approximately 3 hours long and $10/hour. Visit 2 is between 3 and 3 ½ hours long and $20/hour. The four online surveys will be sent within two weeks of Visit 2 and offer the opportunity to earn $60 ($15/survey). If you have further questions, please contact us. 

Q: What kinds of things will I do in the study? 
We will ask you to watch several commercials while your brain activity is measured with functional magnetic resonance imaging (fMRI). We will also ask you to provide a DNA sample, as well as complete several tasks, short interviews, and surveys. For more information, please contact us. 

Q: My child is nervous to go in the fMRI. Will my child be able to get a sense for what it’s like to be in an fMRI before the actual scan? 
Yes, we have a mock scanning room in our facility that we will go to during your child’s first visit with us (the scan occurs in the second visit). In this room, we show your child what the machine looks like and explain how it works. We will also show some videos while they are in the mock scanner and play some of the noises they will hear at the actual scanner. This is a great opportunity for you and your child to ask questions and to voice any concerns you may have! 

Q: What do I have to do for the DNA test? 
We collect a saliva sample for research purposes only. We will not be looking for any genetic risks or diseases. 


Q: If I’m involved in another study, am I allowed to do this study too? 
Most likely yes, although this depends on the nature of the other study you are involved with. Please contact us if you are interested. 

For the Parents: 

Q: As a parent, do I need to be present the whole time my child is in the study? 
No, we only need a parent or legal guardian present for the first half hour of each visit. 

Q: Where will the study take place? Do you provide parking? 
The majority of the study takes place at our lab on Central Campus. We are unable to provide parking for this location, but there are a variety of options in the area. The second visit begins on North Campus. For this portion, we can provide a parking pass.
