This Project Grant award from the National Science Foundation's (NSF) Social, Behavioral, and Economic Sciences (CFDA 47.075) program aims to improve the understanding of how humans perceive and are aware of time. The $721,141 award to George Mason University, to be completed by July 31, 2027, will conduct a series of experiments using electroencephalography (EEG), functional magnetic resonance imaging (fMRI), and transcranial magnetic stimulation (TMS) to identify the brain regions responsible for interval timing and metacognitive awareness of time perception. This research seeks to uncover the neural mechanisms behind how humans recognize and learn from their own timing errors to improve performance, with potential implications for understanding and treating mental health conditions affected by time perception issues. The project also includes cross-disciplinary research experiences for trainees and research-related outreach to local communities. No subawards are planned for this grant.
