Do you love listening to music? Are you curious about how your favorite music affects your brain? The Brain Music Lab at CU Boulder is currently recruiting participants for a research study, Neural Mechanisms of Music Appreciation (CU Boulder IRB #25-0777), investigating favorite music listening and brain activity in young adults.

The total expected time commitment is approximately four hours. Research activities will take place over several weeks, according to your availability and the researchers’ availability. Participating in this study involves:

Even if you enroll in this study, you may not qualify for all of these research activities. Individuals who complete parts one and two will be compensated with a $20 Amazon gift certificate. Individuals who also complete part three will be compensated with an additional $20 Amazon gift certificate, plus an image of their brain!

Complete this form to see if you are eligible.

Doctoral students in the ATLAS Institute have developed a tangible AI product for informal learning. They are seeking feedback to improve the system and make it as fun and enjoyable experience as possible. To join the user study, book a time slot via Calendly.

Participants will try a couple different versions of tangible AI, fill in a survey and give any other feedback verbally. Testing the system and getting your feedback should take about one hour, maybe a bit longer depending on how long you want to speak for.

You can try it as an individual, or bring a friend and try it together. There is no compensation for taking part in the study.

Paid participants are needed for a study investigating tactile and spatial awareness of the piano keyboard, conducted by Alejandro Cremaschi and Luca Pompilio in the College of Music and Mélanie Henry in Integrative Physiology. This study involves a 40-minute session where participants will be asked to reproduce hand spans by memory and to find keys on the piano "by touch" without looking. 

The 40-minute sessions are scheduled at your convenience in the Ramalay Integrative Physiology Lab. To participate you must be 18 years old or older and familiar with note names. Ideally, we would like participants with three or more years of formal piano lessons. Payment is $20 in the form of an Amazon gift card.

If you are interested in participating, contact alejandro.cremaschi@colorado.edu.
