Abstract:
1. A method of testing a subject's cognition and motor timing, comprising: presenting the subject with multiple sequences of stimuli; receiving sensor signals associated with responses by the subject to the stimuli; recording response times in accordance with the sensor signals, wherein the recorded response times are associated with the responses by the subject to the multiple sequences of stimuli, and wherein the response times have an associated distribution; analyzing the distribution of response times for the subject to determine variability in anticipatory timing of the subject; classifying the anticipatory timing of the subject, including the variability of the anticipatory timing of the subject, as normal or abnormal in accordance with a result of the analyzing, and when a resulting classification is abnormal, producing an output indicative of impaired brain function with respect to sensory-motor or anticipatory timing.
