1. A method of conditioning a trainee to identify an object and monitoring the trainee to determine when the trainee subconsciously identifies the object previously associated with a conditioned trainee response, the method comprising: using a processor to select a visceral response-evoking image for evoking the conditioned trainee response, wherein the conditioned trainee response is particular to correspond with the object, and the visceral response-evoking image is particular from a database storing available visceral response-evoking images; attaching at least one sensor to the trainee for detecting trainee biological responses; providing instructions to an electronic device to display a stimulus image depicting the object, wherein the instructions to display the stimulus image are to display the stimulus image within view of the trainee for a first duration that is below conscious awareness of the trainee, and the trainee does not initially associate the conditioned trainee response with the object; providing instructions to the electronic device to display the visceral response-evoking image within view of the trainee after the display of the stimulus image and to display the visceral response-evoking image for a second duration that is below conscious awareness of the trainee in an attempt to link the conditioned trainee response to the object in a mind of the trainee in a manner characterized by an absence of conscious awareness of the link by the trainee; receiving biological response data of the trainee from the at least one sensor while the trainee is performing a task; comparing the biological response data of the trainee to biological responses linked to ones of a plurality of trainee responses, the plurality of trainee responses including the conditioned trainee response; and detecting trainee recognition of the object previously associated with the conditioned trainee response based, in part, on the biological response data being linked to the conditioned trainee response included with the plurality of trainee responses; wherein the conditioned trainee response is below the conscious awareness of the trainee, and providing instructions to display the stimulus image and providing instructions to display the visceral response-evoking image after the display of the stimulus image are repeated at least until the conditioned trainee response is linked to the object in the mind of the trainee.
