The Hungry Mind: Fasting, Sustained Attention, and Working Memory in Muslim College Students Living in America
This research study examines how voluntary fasting affects sustained attention, working memory, and focus in Muslim-American college students, and how sleep, hunger, and stress relate to those changes. We will enroll up to 60 UCF students (ages 18 to 30) who identify as Muslim-American and report voluntary Sunnah fasting on Mondays and/or Thursdays. Participation lasts about 7 days: two in-person visits at the UCF Innovative Center plus at-home wear of a wrist-worn actigraph and a brief daily sleep diary. At both visits (about 60 minutes each), participants complete short surveys on sleep, hunger, fatigue, and stress, three cognitive tasks (SART, 2-Back, Stroop), and a heartbeat perception task using ECG stickers. Visit 1 falls on a fasting day and includes receiving the actigraph; Visit 2 follows about 6 nights of wear and includes returning it. Total in-person time is about 2 hours, with 20 to 35 minutes of at-home time over the week. Risks are minimal, mainly mild skin irritation from the ECG electrodes. There are no guaranteed benefits. Participation is voluntary, with a $20 Amazon gift card prorated across the two visits.
