Understanding neural signals of post-decisional performance monitoring: An integrative review.

Abstract
Performance monitoring is a key cognitive function, allowing to detect mistakes and adapt future behavior. Post-decisional neural signals have been identified that are sensitive to decision accuracy, decision confidence and subsequent adaptation. Here, we review recent work
that supports an understanding of late error/confidence signals in terms of the computational process of post-decisional evidence accumulation. We argue that the error positivity, a positive going centro-parietal potential measured through scalp electrophysiology, reflects the post decisional evidence accumulation process itself, which follows a boundary crossing event
corresponding to initial decision commitment. This proposal provides a powerful explanation for
both the morphological characteristics of the signal and its relation to various expressions of
performance monitoring. Moreover, it suggests that the error positivity –a signal with thus far
unique properties in cognitive neuroscience – can be leveraged to furnish key new insights into the
inputs to, adaptation, and consequences of the post-decisional accumulation process.
