New Metrics for the Primate Equilibrium Platform

Abstract

4 rhesus monkeys were trained to operate a primate equilibrium platform. Multiple baselines were collected for each subject to ensure that performance was stable. Previous research determined time within shock limits as a measure of subject's performance. It is shown here that this measure does not necessarily define how well the subject performs the task. New metrics (RMS, adjusted RMS, Static, and Prime 5) are shown to be more sensitive in detecting differences between subjects during both baseline and treatment (radiation) runs.
