Objective and Subjective Evaluation of Online Error Correction during P300-Based Spelling
Figure 8
(a) Amplitude of pos-ErrP as a function of the accuracy of error detection (microvolts). (b) Amplitude of neg-ErrP as a function of the sensitivity of error detection (microvolts). (c) Amplitude of N1 as a function of the global spelling accuracy (microvolts). Each diamond represents a participant, and values represent correlation coefficients.
