Measuring Rotary Pursuit Performance by Kymographic Recording

Performance in rotary pursuit has usually been measured in terms of cumulative time of completion of stylus-target electrical contact during trials of given length (1, 2, 5, 6, 7 ) . This method of measurement gives an index of performance, but obscures the nature of the temporal and spatial patterns of movement. The purpose of this paper is to report a method for recardine; the temporal pattern of stylus-target contacts, and to discuss some of its implications.
