Neural mechanisms of performance monitoring and adaptive control

Monitoring for erroneous and unexpected action outcomes is essential to determine when control is needed for goal achievement. Research of the last 20 years has provided excellent tools to noninvasively study performance monitoring signals in humans and to test current theories of cognitive control. Particularly model-based analyses of EEG and fMRI data enable us to track the feedback cycle of valuation, decision making, outcome monitoring and adaptation. After giving an overview of studies investigating performance monitoring signals I will focus on the investigation of trial-by-trial post-error adaptation in healthy participants and neuropsychiatric patients. Furthermore, I will discuss pharmacological challenge studies elucidating the roles of serotonin in post-error slowing and of acetylcholine in post-error increase in selective attention. I will conclude the presentation with an outlook on future research lines needed for our understanding of goal-directed, adaptive, and flexible human behavior.
