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 desired trainee response, the method comprising: using a processor to select a visceral response-evoking image for evoking the desired trainee response, wherein the desired trainee response is selected to correspond with the object, and the visceral response-evoking image is selected 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 desired 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 desired 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 different ones of a plurality of trainee responses, the plurality of trainee responses including the desired trainee response; and detecting trainee recognition of the object previously associated with the desired trainee response based, in part, on the biological response data being linked to the desired trainee response included with the plurality of trainee responses; wherein the desired trainee response is below the conscious awareness of the trainee.
