Figure 8

Speed vs. Accuracy. Scatter plot of the spelling speed in dependence of the levelwise spelling accuracy. Each data point refers to one experimental block of one participant (nine data points per participant). The blocks in which the ErrP detection was turned off are depicted as black circles, the blocks in which classifier A was used to detect ErrPs are depicted as magenta crosses and the blocks of classifier B are depicted as blue diamonds. For each condition a line was fitted to the data using least squares. The error bars depict the standard deviation of the accuracy in the bands 100-90%, 90-80%, 80-70% and 70-60%.
