A method is provided for testing a subject's cognitive performance by testing movements under the subject's voluntary control. The method includes prompting the subject to perform a plurality of iterations of a physical task. The physical task includes a movement of a first body part of the subject's body. For each iteration of the plurality of iterations of the physical task, one or more measurements corresponding to the movement of the first body part are obtained. A nominal path of the first body part is determined based on the measurements obtained from a first subset of the plurality of iterations of the physical task. A variability metric is generated by analyzing a plurality of measurements with respect to the nominal path. The variability metric is compared with a predetermined baseline to categorize the cognitive performance of the subject.
