Experiment 1. Comparison of human and computer scoring: correlation and linear fit. (A) Two human observers scored the same 40 mice freezing during 5-min context and tone tests (80 observations for each observer; % time freezing). The observations between the two observers exhibited a high correlation and excellent linear fit. (B) Computer and human (average of the two observers) scores were compared. The observations exhibited a high correlation and excellent linear fit, indicating that the computerized scoring system yielded accurate scores across a wide range of freezing.
