Chew, Blain et al. measured participants’ mood with repeated questions and their brain activity with fMRI as they earned two types of rewards. Participants chose a box to earn points tied to how much money they would earn at the end of the task — an extrinsic reward.

The participants answered questions about how they felt throughout the study.
