Does Caffeine Facilitate Human Reward Learning Behaviors?

Sponsor: Yu-Shiuan Lin

View on ClinicalTrials.gov

Summary

"Learning from the rewards" is underlying the formulation of knowledge and habits in daily life. Caffeine is the most commonly used "psychoactive" substance that could change one's mind state by affecting the brain and nervous system. By such effects, caffeine enhances reward signals - dopamine - in human brains. In this research study, we will find out whether taking caffeine acutely or daily can enhance reward learning processes.
