The Effect of Modafinil on Affective and Cognitive Processing

June 14, 2019 updated by: Benjamin Becker, University of Electronic Science and Technology of China

The Effect of Modafinil on Neural Processing During the Interference and Feedback Based Learning Task

The study aims to examine whether a single dose of modafinil (200mg, p.o.) can affect feedback-based learning and interference processing in healthy male subjects.

Detailed Description

Based on previous animal and human research suggesting a catecholamine-mediated, potentially pro-cognitive, mechanism of action of modafinil, the present study seeks to explore effects of modafinil on feedback-based learning and interference processing in healthy subjects. To this end, the present randomized double-blind, between-subject, placebo-controlled pharmaco-fMRI experiment plans to determine the behavioral and neural effects of a single dose of p.o.modafinil (200mg) versus placebo on validated feedback-based learning and emotional/non-emotional cognitive conflict paradigms. To control for potential effects of pre-medication personality traits as well as effects of modafinil on subjective task performance, subjects will be administered pre-treatment assessing relevant personality traits and post-treatment assessments of meta-cognitive confidence estimation.
