Abstract
A mounting and control arrangement is provided for a threaded rod such that a subject spinning a split nut on the threaded rod can be 'timed' for successive trial rotations. One series of times are taken with the threaded rod stationary. One or more trial times are taken with the threaded rod being rotated at a speed that requires more concentration and effort on the part of the subject. The various time trials are assimilated to provide a 'persistence' rating for the subject.
