Claim One:
1. A system to detect sleep stages of a subject, the system comprising: a stimulus source configured to provide stimuli to the subject; one or more sensors that generate output signals conveying information related to one or more physiological parameters of the subject; and one or more processors configured to execute computer program modules, the computer program modules comprising: a reaction module configured to analyze, based on the one or more physiological parameters, reactions to the stimuli provided by the stimulus source; a sleep stage module configured to: i) generate a sleep stage estimation of the subject based on one or both of the analyzed reactions and/or the one or more physiological parameters, and ii) determine a probability of accuracy of the sleep stage estimation; a comparison module configured to determine whether the probability of accuracy breaches a predetermined threshold; and a stimulus control module configured to, responsive to the probability of accuracy failing to breach the predetermined threshold, control the stimulus source to provide a reassessment stimulus to the subject, wherein the reaction module is further configured to analyze a reaction to the reassessment stimulus, wherein the sleep stage module is further configured to reassess one or both of the sleep stage estimation of the subject and/or the probability of accuracy based on the analyzed reaction to the reassessment stimulus.
