Abstract: 
A commentary on papers by Klein, Pockett and Trevena & Miller, in this issue, is given. Average shift in the point of subjective equality (PSE), calculated by Klein on Libet’s data, and corresponding change in mean shift, calculated by Libet et al. (1983), may be “corrected”, taking as reference point the end of the minimum train duration. Values obtained, if significant, indicate a latency for conscious sensation of the skin stimulus of at least 230 ms. Pockett’s main conclusions are favored, but her explanation of peripheral-lemniscal couplings is found unconvincing. Trevena & Miller’s paper unsuccessfully tries to rescue a dualist interactionist view. Libet’s method of timing intentions is thoroughly criticized.
