Two-dimensional compensatory tracking of a low frequency random wave target was studied. Experiment 1 was simple tracking by componental one-dimensional movement of the stick either right-and-left (the X component) or back-and-forth (the Y component). Ten subjects served the experiment. The superiority of the performance in the X dimensional task over that in the Y dimensional one was found. The learning characteristics also differed. Experiment 2 was complex tracking by simultaneous two-dimensional movement of the stick. Seven subjects served the experiment. It was found that the two-dimensional tracking was specifiable by the combination of the properties of the X and Y components which were found in Experiment I. Validity of the componental analysis of two dimensional tracking was concluded.
