Study Summary

The purpose of this balanced-placebo design study is to pilot a larger study to further explore the current evidence that stimulant medications are not cognitive enhancers, despite this rampant belief in young adults. While the lack of cognitive enhancement from stimulant medication has been documented in prior research, this study is the first to utilize neuroimaging technology to examine brain regions activated during neurocognitive tasks when participants believe they have been administered stimulant medication or placebo.

Primary Outcome

Using a balanced placebo design, participants were either administered mixed amphetamine salts or placebo. Their cognitive performance was assessed in the MRI scanner. The main outcome measure was the feasibility of participants attending four neuroimaging sessions.

Interventions
