Bibliographic Details
Title: Executive control and response expectancy: A Laplacian ERP study.
Authors: Meckler, Cedric (AUTHOR), Allain, Sonia (AUTHOR), Carbonnell, Laurence (AUTHOR), Hasbroucq, Thierry (AUTHOR), Burle, Boris (AUTHOR), Vidal, Franck (AUTHOR)
Source: Psychophysiology. Mar2011, Vol. 48 Issue 3, p303-311. 9p. 2 Charts, 3 Graphs.
Subjects: Error, Reaction time, Laplace transformation, Electromyography, Electrooculography, Analysis of variance
Abstract: The event-related potential called 'Error Negativity' (Ne, ERN), which appears when subjects commit errors in choice reaction time tasks, is a marker of response monitoring. By introducing a response probability bias, we show that the Ne is sensitive to response expectancy. We further show that the small negativity evoked by correct responses (Ne-like, CRN) is also sensitive to response expectancy: On unexpected responses, the former decreases while the latter increases to such an extent that the amplitudes of the two components are in the same range of magnitude. Although the sensitivity of the Ne to response expectancy is compatible with the current models accounting for the Ne, the common sensitivity of the Ne and the Ne-like supports the idea that they reflect functionally similar monitoring processes.
