We applied Mann-Whitney U tests to compare the number of high performance blocks for the two response buttons, and we found that the number of high performance blocks was significantly higher for the left button than for the right button in the analysis of blockSensitivity (U = 528.50, p = 0.048) and that the difference was marginally significant for the blockSpecificity (U = 545.00, p = 0.072).
