Feedback Related Negativity

in response to errors committed by study participants during simple choice response tasks. Component characteristics[edit] The ERN is a sharp negative going signal which begins about the same time an incorrect motor response begins, (response locked event-related potential), and typically peaks from 80-150 milliseconds (ms) after the erroneous response begins (or 40-80 ms after the onset of electromyographic activity).[6][7][8][9][10][2] The ERN is the largest at frontal and central electrode sites.[2] A typical method for determining the average ERN amplitude for an individual involves calculating the peak-to-peak difference in voltage between the average of the most negative peaks 1-150 ms after response onset, and the average amplitude of positive peaks 100-0 ms before response onset.[11] For optimal resolution of the signal, reference electrodes are typically placed behind both ears using either hardware or arithmetically linked mastoid electrodes.[7] Main paradigms[edit] Any paradigm in which mistakes are made during motor responses can be used to measure the ERN. The most important feature of any ERN paradigm is obtaining a sufficient number of errors in the participant's responses. Early experiments identifying the component used a variety of techniques, including word and tone identification, and categorical discrimination (e.g. ar

Psychology and 2Neuroscience Program, University of Michigan, Ann Arbor, Michigan 48109  Next Section Introduction Goal-directed behavior relies on the ability to detect errors and to correct the action(s) that led to the error. Research on error https://en.wikipedia.org/wiki/Error-related_negativity detection really took off with the discovery almost 20 years ago of two event-related potential (ERP) components found within the human EEG: the error-related negativity [ERN; or error negativity (Ne)] and the error positivity (Pe) (Falkenstein et al., 1991; Gehring et al., 1993). The ERN is a negative deflection that peaks ∼50–80 ms after an erroneous button press. The Pe is a positive deflection that peaks ∼100–200 ms after an erroneous button http://www.jneurosci.org/content/31/16/5891.full press. While most research has focused on the role of the ERN in error detection, recent research is beginning to uncover the function of the Pe. Several influential theories have been put forth to explain the computation underlying the ERN (Coles et al., 2001; Holroyd and Coles, 2002; Yeung et al., 2004). Specifically, the ERN has been proposed to reflect either competition between the erroneous and correct response representations (Yeung et al., 2004), a mismatch between the actual and expected correct response (Coles et al., 2001), or the result of less-than-expected reward outcomes (Holroyd and Coles, 2002). Thus, the ERN appears to represent an internal signal that an error is likely or has occurred. However, these theories fail to account for the role of the Pe in error detection. Nevertheless, research has begun to identify conditions that modulate this ERP component (Overbeek et al., 2005). The most consistent finding is that the Pe is generally larger on trials where participants are consciously aware that an error was made, whereas the ERN is similar for perceived and unperceived errors. This is consistent with the possibility that the Pe reflects the motivational significance of an error. Consciously perceived errors would be more significant, and more likely to lead to correcting one's erroneous actions, than

When researchers began addressing the electrophysiology of subjective error awareness more than a decade ago, the role of the ERN, alongside the subsequently occurring error positivity (Pe), was an obvious locus of attention. However, the first two studies expli
