Electrophysiological correlates of performance monitoring in middle and late adolescence
… 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 measure of response …

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 …

Zusammenhang zwischen Fehlermonitoring, Persönlichkeitsmerkmalen und Serotonintransporterpolymorphismus
… 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 dreidimensional die genaue …

Performance Monitoring: Error Detection and the Error-Related Negativity in Choice-Related Time Tasks
… 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 reaction time tasks, the monitoring process compares a …

Evaluating Changes in Error-Monitoring Electrocortcial Responses as an Outcome of Attention Bias Modification Training
… of ABM training using error-related negativity (ERN) an event-related potential (ERP) that is associated with an error-monitoring response after an individual commits an error. To elicit an erroneous response a modified flanker task paradigm was used. The ERN has the potential to be used as a …

The Role of Awareness in the Error -Processing of Involuntary Eye Movements
… as manifested by error-related components (ERN, Pe), and oculomotor capture. From the results of two experiments it appears that oculomotor capture is processed similar to other kinds of interruptions of ongoing goal-directed activity, and is registered even in the absence of subjective …

The Error-Related Negativity: Evidence for a Neural Mechanism for Error-Related Processing
… included a sentence verification task, a Sternberg memory search task, and two letter discrimination tasks. In all these experiments, a negative-going deflection (the error-related negativity, or ERN) in the event-related brain potential began around the time of error onset and peaked about …

Unterstützung von Kohärenzbildung beim kooperativen und individuellen Lernen mit externen Repräsentationen
… Ist das Interpretieren oder das Konstruieren externer Repräsentationen (ERn) lernförderlicher? (2) Profitieren Lernende von einer Anleitung zur Elaboration des Zusammenhangs alternativer Repräsentationen?. (3) Ist kooperatives Problemlösen mittels ERn individuellem Problemlösen bzgl. des …

Developmental and individual differences in novelty and error detection in 10-year-old children and young adults /
… typically elicit a negative ERP deflection (the ERN) with a frontal-central scalp distribution that may reflect response monitoring. There is also evidence of a positive ERP peak (the Pe) with a posterior scalp distribution which may reflect subjective recognition of a response. Both children and …

Cardiorespiratory Influences on Executive Control Function
… both a modified flanker task and a modified Sternberg task under task instruction conditions that stressed speed and accuracy. A graded maximal exercise test (GXT) was used to measure cardiorespiratory fitness by assessing maximal oxygen uptake (VO2max). The error-related negativity (ERN), …

Exploring the neural link between performance monitoring and emotional responses to social exclusion : an EEG study in an adolescent sample
… P3 and LPP for the Cyberball paradigm, and ERN and Pe for the Go/No-Go task. Preliminary correlational analyses and regression analyses were performed on the ERP components of Cyberball and Go/No-Go. The analyses yielded no significant results, however several limitations may have influenced …

Cortical and autonomic modulation of attentional control /
… control (N2/P3) and error-related processes (ERN/Pe) were analyzed. Results indicated that response inhibition was unrelated to phasic vagal cardiac control, as indexed by respiratory sinus arrhythmia (RSA). However, higher resting RSA was associated with larger ERN ampUtude for the highest …
