Applied Error Related Negativity: Single Electrode Electroencephalography in Complex Visual Stimuli
Error related negativity (ERN) is a pronounced negative evoked response potential (ERP) that follows a known error. This neural pattern has the potential to communicate user awareness of incorrect actions within milliseconds. While the implications for human-machine interface and augmented …

Reinforcement Learning and the Error -Related Negativity: A Computational and Neurophysiological Investigation
… for reinforcement learning, and a ""generic"" error-processing system associated with anterior cingulate cortex. The existence of the error-processing system has been inferred from the ""Error-Related Negativity,"" a component of the event-related brain potential elicited when human subjects …

The Error-Related Negativity: Evidence for a Neural Mechanism for Error-Related Processing
The analysis of response-locked event-related potential (ERP) waveforms from several experiments points to the existence of a neural system involved in processing information associated with errors in choice reaction time tasks. The experiments included a sentence verification task, a Sternberg …

Performance Monitoring: Error Detection and the Error-Related Negativity in Choice-Related Time Tasks
… processing system. A component of the event-related brain potential, the error-related negativity (ERN), appears to be a manifestation of a process that monitors the accuracy of performance. Current evidence suggests that the component is generated in the anterior cingulate cortex. In choice …

Impacting factors for attention in children who are internationally adopted
… (IA) children often have attention deficits related to the unique experience they have with early-life stress. The current study focused on how elements of the care experienced by IA children related to attention deficits. Specifically, this study assessed how length of care and type of care …

Individual Differences in the Dopaminergic Reward System: The Effect of Genetic Risk on Neural Reward Sensitivity and Risky Choice
… on neural reward sensitivity (assessed by event-related potentials, specifically, the medial-frontal negativity [MFN] and the error-related negativity), impulsivity (assessed via self-report), and risky choice (measured using the Balloon Analogue Risk Task and self-report measures). Results …

Evaluating Changes in Error-Monitoring Electrocortcial Responses as an Outcome of Attention Bias Modification Training
… attention bias to threat as well as heightened error-monitoring following an erroneous response. In an effort to reduce an anxious individual’s attention bias to threat, an attention training paradigm known as attention bias modification (ABM) was developed. While ABM training has demonstrated …

Zusammenhang zwischen Fehlermonitoring, Persönlichkeitsmerkmalen und Serotonintransporterpolymorphismus
… den EKP´s nach Fehleingaben ist besonders die „error-related negativity“ (ERN) sowie die Positivität P300 (Pe) hervorzuheben. In dieser Arbeit wurde die ERN sowie die Pe bei 39 Probanden untersucht und genauer klassifiziert. Zusätzlich wurde mit Hilfe der Quellenlokalisationsmethode LORETA …

Electrophysiological correlates of performance monitoring in middle and late adolescence
… of the ACC may be indirectly measured using the error-related negativity (ERN), an event-related potential (ERP) component that is hypothesized to reflect activity of the automatic response monitoring system. To date, no studies have examined the measurement reliability of the ERN as a trait-like …

Cardiorespiratory Influences on Executive Control Function
… by assessing maximal oxygen uptake (VO2max). The error-related negativity (ERN), error positivity (Pe), and inhibitory N2 components, as well as behavioral measures of response speed, accuracy, post-error accuracy, and post-error slowing were each regressed on fitness (VO2max percentile) to …

Spiking Neural Network Framework for Brain Computer Interfaces
… the baseline EEG-based performance of P300 and error-related negativity (ERN). The efficacy of the SNN depended on the neuron properties to an extent, and leveraging the heterogeneity of the properties could provide a better spike representation of the EEG. For ease of computation, the majority …
