Error awareness and the error-related negativity: evaluating the first decade of evidence

Jan R. Wessel
2012 Frontiers in Human Neuroscience  
Here, I review those studies that explicitly dealt with the role of the error-related ERPs in subjective error awareness, and try to explain the differences in reported effects of error awareness on ERN  ...  However, the first two studies explicitly addressing the role of error-related event-related brain potentials (ERPs) would already set the tone for what still remains a controversy today: in contrast to  ...  Markus Ullsperger on the original study , of which I used a subset of data to test the error correction account of the ERN, and for previous discussions about many of the issues presented in this article  ...

2018 Scientific Reports  
The second, is a brain-computer interface that utilizes a neural response, known as Error-Related Potentials (ErrPs), which is inherently generated whenever the subject observes an erroneous action.  ...  Towards this direction, the most common approach is to detect Error-Related Potentials (ErrPs), a special type of Event-Related Potentials (ERPs) that appear shortly after the user recognizes an error.  ...  Acknowledgements This work is part of project MAMEM that has received funding from the European Union's Horizon 2020 research and innovation programme under grant agreement No.: 644780.  ...

Error-Related EEG Potentials Generated During Simulated Brain–Computer Interaction

P.W. Ferrez, J. del R. Millan
2008 IEEE Transactions on Biomedical Engineering  
Brain-computer interfaces (BCIs) are prone to errors in the recognition of subject's intent.  ...  An elegant approach to improve the accuracy of BCIs consists in a verification procedure directly based on the presence of error-related potentials (ErrP) in the electroencephalogram (EEG) recorded right  ...  These associative areas (somatosensory association cortex; Brodmann areas 5 and 7) could be related to the fact that the subject becomes aware of the error.  ...

Anticipation- and error-related EEG signals during realistic human-machine interaction: A study on visual and tactile feedback

R. Chavarriaga, X. Perrin, R. Siegwart, J. del R Millan
2012 2012 Annual International Conference of the IEEE Engineering in Medicine and Biology Society  
Experiments with 6 subjects show brain activity consistent with previous studies using simpler stimuli, both at the level of ERPs and single trial classification.  ...  We focus on cortical potentials linked to the anticipation of future events (i.e. the contingent negative variation, CNV) and error-related potentials elicited by both visual and tactile feedback.  ...  In particular, EEG signatures of anticipation [1] and error awareness [2] may be exploited by brain-machine interfacing (BMI) systems to complement traditional control paradigms (e.g. based on kinesthetic  ...

Conscious perception of errors and its relation to the anterior insula

Markus Ullsperger, Helga A. Harsay, Jan R. Wessel, K. Richard Ridderinkhof
2010 Brain Structure and Function  
We discuss the role of the anterior insula in generating versus perceiving autonomic responses and as a key player in balancing effortful task-related and restingstate activity.  ...  We focus specifically on the anterior insula, which has been shown to be (a) reliably activated during performance monitoring and (b) modulated by error awareness.  ...  Recent functional connectivity studies seem to suggest that this salience network is crucial for balancing the engagement of task-related, rest-related activity and ongoing activity in the human brain.  ...

Designing Future BCIs: Beyond the Bit Rate [chapter]

Melissa Quek, Johannes Höhne, Roderick Murray-Smith, Michael Tangermann
2012 Towards Practical Brain-Computer Interfaces  
The scope of this chapter is limited to applications where a Brain-Computer Interface (BCI) is used as an explicit interaction technique.  ...  The term "extreme" is used because the BCI interaction is much slower, noisier and more error-prone compared to other input devices, and lacks proprioceptive feedback.  ...  Issues Specific to BCI Paradigms Since brain signals acquired with EEG are very weak, noisy and non-stationary, there is an entire research area in signal processing [40, 41, 68, 69] and classification  ...
