Using Neuroscience to Optimize Digital Health Interventions across Adulthood (2019-2020)
This Bass Connections project combined approaches from neuroscience, psychology and global health to identify ways to individually motivate adults to become more physically active and make healthier food choices in daily life. In a community sample of healthy adults (ages 30-80), the project used human brain imaging (fMRI) to assess the sensitivity of motivational brain systems (e.g., striatum and medial prefrontal cortex) to socioemotionally-framed health messages.
After neuroimaging, participants had their activity and eating habits continuously monitored for three months while receiving physical activity and eating-related messages on their mobile phones in the form of programmed voice-over IP and/or text messages (developed in partnership with the Duke Global Digital Health Science Center). The team used the neural measures as predictors of the effectiveness of specific messages delivered via mobile phone to increase activity in daily life.
Ph.D. student Jaime Castrellon (Psychology & Neuroscience) received the 2020 Bass Connections Award for Outstanding Mentorship for his work with this team.
