Methods for scoring continuous records of tracking performance with analog signal correlator and frequency analysis systems are described. An index of lead-lag obtained from the correlator output is compared with discrete lead-lag scores obtained by hand-scoring oscillographic records for three tasks which differ in amount of task coherence. The results indicate relatively high agreement between the two scoring methods and support the use of the correlator as the more efficient method. Sample data from the analog frequency analysis system are compared for operators with high and low integrated error scores. The results indicate consistently greater power in the response than in the input at the fundamental for both good and poor Ss, indicating a tendency to overshoot the target with the primary movement, but relatively more power in the initial odd harmonics for the better Ss. Ratios of target spectra to response spectra provide transfer functions for the human operator. |
