Thank you for your interest in the DOME Lab!

We frequently have different ways for children and families to be involved with our work. Announcements for specific studies will be posted below. If you are not eligible for a current project, please consider joining our Montana Children and Families Research Database, which will be used to invite families to participate in future work. 

If you have additional questions, scroll through our Frequently Asked Questions below or feel free to contact us.

We are currently scheduling follow-up visits for families who are part of our Study of Preschoolers' Attention, Cognition, and Emotion (SPACE)! Children will visit our laboratory to play a series of games. Parents will be asked to complete a packet of questionnaires. Families will receive monetary compensation for their time and children will receive a small prize as a token of appreciation. Contact us to learn more!! 


We are recruiting mothers-to-be in their first or second trimester of pregnancy for our Montana Minds of Mothers Study! Participants will be asked to visit our laboratory to complete questionnaire measures and a series of computer tasks during the second and third trimester of pregnancy and again when babies are 4 months old. Heart rate and brain activity will be monitored non-invasively for you and your baby. Mothers who complete all three visits will receive $200. Contact us for more information or sign up to participate online. Ask about travel reimbursement for families traveling more than 100 miles.

Frequently asked Questions:

What does the DOME Lab study?

The DOME lab studies the ways that biological and environmental factors influence development across the lifespan. Our primary biological measures include recordings of neural activity (Electroencephalography, or EEG), heart rate, and levels of stress hormones (Cortisol). Our environmental measures include everything from parent personality to peer relationships and transitions through major life events (e.g., starting school). We also frequently include cognitive measures such as attention and cognitive control. Children enter the lab with a range of comfort and ability with all of our measures and frankly, we prefer it this way! Parents know that all children are different and we want to understand what these processes look like in all types of children.

Where are you located?

We are located on the second floor of AJM Johnson Hall, just west of the Strand Union Building at Montana State University.

Is parking available?

Yes. The MSU parking office offers a permit to our lab that allows our participants to park right outside of our building. AJM Johnson Hall also has ramp and elevator access if needed. Our lab will cover the costs of your parking during your visit.

Can I ride the bus to your lab?

If you live in or near Bozeman you can. The Streamline is a free bus service provided by the city of Bozeman. All of the Streamline routes drop off at the Strand Union Building, which is right next door to us.

What ages do you work with?

Dr. Brooker has worked with a variety of ages from infancy through adolescence. Children of all ages are invited to join our Montana Children and Families Research Database. Ages of children who are being recruited for studies will vary over time. See our Projects Tab for the most current recruitment information.

Will I be with my child the whole time?

Usually. You will be present for all procedures for children under age 5. You may be present for procedures with older children if requested. In some of our work, there may even be games for you and your child to play together.

How are hormones collected from children?

We measure hormone concentrations in saliva samples. Most often, this simply entails children holding a cotton swab under their tongue for roughly 90 seconds or until it is thoroughly wetted. We have found that many preschoolers can collect the saliva samples for us on their own!

What is EEG and how is it collected?

EEG is the electrical activity that is naturally generated by everyone's brain. We make a recording of the EEG signal using an cap made of stretchy fabric that is placed on your child’s head. Small electrodes are snapped into holders on the cap so that we can record from a variety of locations on the scalp while children play games on our computer. Recordings work best with clean, dry hair that is free of products.

Are there any risks associated with participating that I should know about?

There are no risks associated with any of our procedures beyond those that children experience in their daily lives. All of our procedures were developed for use in research laboratories and are safe for participants of all ages.

Will I be paid for my participation?

We understand that your time is precious and do offer payment to families who participate in our research. In addition, your child will receive a token of appreciation for being part of our study.
