Comparison of human and computer scoring: impact of shock intensity and modality. (A) Shock intensity. Different groups of mice were given training under four shock intensities, which impacted freezing (context and tone, mean % time ± s.e.m.) measured on separate days. The computer accurately tracked the effect of shock intensity measured by human observers. (B) Modality. Mice were given both context and tone freezing tests (on separate days). The computer accurately mimicked the difference in conditioning to the tone and context detected by human observers.
