Overview of the 11 runs and the two methods used for calculating feedback.

<p>In block I, continuous visual feedback was given by a classifier that had been pre-computed with the <i>Zero-Training</i> method, see Section “Construction of Classifiers”. Blocks II to V each contained one run with <i>Zero-Training</i> feedback and one run with ordinary CSP feedback. The order of the two feedback methods was chosen randomly and remained unknown to the subject. The use of continuous visual feedback and no continuous visual feedback alternated regularly between blocks II to V.
