Method: In two experiments, participants responded with the left and right hand to leftward and rightward arrows presented for different durations (0-117 ms). Different stimulus durations were fully randomized in Experiment 1 but run in separate blocks in Experiment 2. Results: In both experiments, percent correct and Pe amplitude increased with increasing stimulus duration. By contrast, ERN was only found for (blocked) longer stimulus durations of Experiment 2, and absent with the randomized stimulus durations of Experiment 1. Conclusions: Presence of a Pe in the absence of ERN in Experiment 1 suggests that conscious error processing can occur without prior unconscious error detection. To explain the pattern of ERN/Pe effects, two separate processes of error detection are suggested, operating independently at the levels of object-based (Pe) and purely perceptual stimulus representations (ERN), respectively. Significance: A novel model of error processing is developed, elaborating on the reinforcement-learning theory of ERN. It is suggested that giving a response retrieves appropriate stimulus representations whose activation typically precedes this response; in case of mismatch with actually present stimuli, ERN is elicited.

A precue indicated a low or high force before a stimulus signaled the execution of the same or opposite force. An incorrectly exerted force was assumed to involve an error of force selection if the opposite force was required (invalid precue), and an error of force execution if the same force was required (valid precue). The task was repeated to examine any improvements in monitoring sensitivity. No force-related effects were observed on MFN amplitude. Although performance improved, there was no evidence of a force-error sensitive monitoring system. As the MFN and motor activity were affected by the precue invalidity regardless of the response outcome, the MFN might reflect the activity of a general action-evaluation system that is indirectly related to motor activation."],["dc.identifier.doi","10.1111/j.1469-8986.2011.01282.x"],["dc.identifier.isi","000298593800006"],["dc.identifier.pmid","21895690"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/27841"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Wiley-blackwell"],["dc.relation.issn","0048-5772"],["dc.title","Monitoring force errors: Medial-frontal negativity in a unimanual force-production task"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]
