We have recorded the ERPs while human subjects performed in a perceptual length discrimination task (LDT) in which they have to discriminate the length of lines. Subjects received feedback after correct or incorrect behavioral responses.Trial-by-trial and population analyses confirmed that, when feedback was provided, the FRN wave followed incorrect choices. Interestingly, a positive wave not previously described, the feedback-related positivity (FRP) followed incorrect choices.engPerformance-monitoringPerceptual decision makingEvent-related potentialsFeedbackTrial by trialMaterias::Investigación::61 Psicología::6106 Psicología experimental::610601 Actividad cerebralMaterias::Investigación::61 Psicología::6106 Psicología experimental::610604 Análisis experimental de la conductaMaterias::Investigación::61 Psicología::6106 Psicología experimental::610609 Procesos de percepciónMaterias::Investigación::61 Psicología::6106 Psicología experimental::610610 Psicología fisiológicaconference outputopen access
