This is an fMRI study of the magnitude effect in intertemporal choice, which refers to the phenomenon that people become more patient as the magnitude of all of their options increases. We scanned participants in 2 blocked sessions each of low and high magnitude decisions. The study was conducted at two different sites with different scanners and data acquisition specifications.
