Course overview

The article examines how negative reinforcement mechanisms contribute to methamphetamine use disorder. It reviews evidence from subjective experience, behavioral studies, neuroimaging, and event-related potentials to understand the processes that maintain addiction. The review emphasizes that methamphetamine use is often driven by the short-term reduction of unpleasant physical or emotional sensations, which reinforces continued use despite severe long-term consequences. The article also explores how diminished cognitive control, altered emotional processing, and impaired decision-making abilities contribute to the persistence of methamphetamine use and highlights the need for effective treatment interventions.
