Abstract:
Error-related negativity is an event-related potential component that is observed when participants make errors and reflects action monitoring that involves error detection. In this study, an over-response error (responding with both hands when participants were asked to respond with only one hand) and an under-response error (responding with one hand when asked to respond with both hands) were assessed by the characteristics of the error-related negativity during a modified Eriksen flankers task. The results indicated that a bimanual response error also elicited the error-related negativity, and that the onset latency of the error-related negativity was shorter for an over-response error than for an under-response error. Thus, these results suggest that the error-detection process is more sensitive to an unnecessary response than to an insufficient response.

Types of Errors: Detection and Minimization
Absolute error in a measurement is the numerical difference from the true or central value. Relative error is the ratio between absolute error and the true or central value, expressed as a percentage.
Errors can be classified by source, magnitude, and sign. There are three types of errors: systematic, random, and gross.
