Creativity is a fundamental component of human thinking and researchers have largely neglected the biological basis of this important cognition until now. This variable was examined along with mind-wandering, a phenomena in the human mind in which one has thoughts unrelated to a primary task. By collecting resting state electroencephalography (EEG) data, both creativity and mind-wandering can be examined together to search for a link to one’s neural activation. College students in their early twenties were told to complete 12 120-second intervals of focused breathing while resting-state EEG data was recorded with both their eyes open and eyes closed as a control. After each interval was completed, the participant answered a survey question regarding their time focused on the task as a method of measuring their rate of mind-wandering. At the end of the EEG data collection, participants were told to take a Remote Associations Test as a method of quantifying one’s level of creativity. There is a statistically-significant positive relationship between the EEG component “alpha” and one’s level of creativity. There is also a positive relationship between one’s rate of mind-wandering and their level of creativity. There is a clear biological link to creativity, as well as how it relates to mind-wandering.
