INTRODUCTION

English translation pending.

CORE DEFINITION

The error-related negativity is an event-related potential component generated in or near the anterior cingulate cortex and observed within roughly fifty to one hundred milliseconds after an incorrect response, reflecting the brain's rapid and automatic detection of a mismatch between the behavioural outcome and expectation. The core claim is that the brain monitors ongoing action automatically and signals a mismatch before conscious awareness of the error. The qualification is that the component indexes conflict and performance monitoring rather than any emotional experience, so it should not be read as regret or as an indicator of how the person feels about the mistake.

SCAFFOLDING EFFECT

Reduce cognitive load

- Intuition check: treat a pre-verbal sense that something is wrong as a signal worth examining. - Error design: build systems that detect mistakes fast rather than assuming care prevents them. - Feedback study: measure automatic error monitoring separately from the person's stated reaction.

Anchor fast decisions

Comparing an intended response with the one actually executed requires the outcome to be evaluated against a representation of the goal, and the anterior cingulate cortex performs this comparison continuously. A mismatch generates a detectable electrical deflection before the error reaches awareness, which is why people often report knowing something was wrong before they could say why. Early detection gives the control system time to slow down and correct.
