Performance monitoring is crucial for achieving goal-directed performance. In recent years, a large number of studies has addressed the question how errors are detected and how error detection triggers behavioral adjustments that prevent the occurrence of further errors. However, for behavioral adjustments to be really adaptive, it is not only necessary to detect an error but also to evaluate the type of error. In a series of studies, we investigated how performance monitoring deals with different error types (e.g., internally-caused errors vs. externally-caused errors, attention errors vs. non-attention errors). By considering behavioral data and event-related potentials, we provided evidence that the type of behavioral adjustment depends on the type of error, and that the evaluation of error type is already reflected in early error-related brain activity. Our results suggest that error evaluation is far more complex than assumed by current models of performance monitoring. It involves a fast evaluation of error type on several dimensions.
