1. A system for providing a cognitive or sensory assessment, comprising: a sensor device interfaced to a subject to detect physiological signals exhibited by the subject before, during, and after a presentation of a sequence of stimuli to the subject, the sequence of stimuli based on a cognitive-sensory profile category from among one or more of a cognitive performance profile, a sensory performance profile, or a cognitive and sensory performance profile; a data processing system in communication with the sensor device and structured to include one or more memory units and one or more processors configured to process the physiological signals to generate an information set including one or more quantitative values associated with the cognitive-sensory profile category, wherein the data processing system includes: a local computer located proximate and in communication with the sensor device to receive the detected physiological signals from the sensor device, the local computer configured to conduct initial processing of the detected physiological signals to produce initial physiological signal data, and a remote computer in communication with the local computer via a communication network or link to receive the initial physiological signal data from the local computer and to process the initial physiological signal data to generate the information set including the one or more quantitative values associated with the cognitive-sensory profile category, wherein the initial physiological signal data includes a time interval associated with the detected physiological signals based on presented stimuli and the cognitive-sensory profile category, and wherein the remote computer is configured to: group the initial physiological signal data corresponding to the time interval into one or more grouped data sets, and provide a statistical measure of a relationship across or within the grouped data sets to generate the one or more quantitative values; a stimulus delivery device at a location of the subject and configured to produce the sequence of stimuli that is presented to the subject, wherein the stimuli includes at least one of a visual, auditory, olfactory, tactile, or gustatory stimulating medium; and a stimulus presentation computer in communication with the remote computer and the stimulus delivery device, the stimulus presentation computer configured to modify the sequence of stimuli based at least in part on the information set during presentation of the sequence of stimuli to the subject and produce a modified sequence of stimuli that is individualized with respect to the subject, and to cause the stimulus delivery device to present the modified sequence of stimuli to the subject, wherein the information set is generated by the data processing system without requiring a behavioral response by the subject to the sequence of stimuli.
