1. A method of conditioning a trainee's firearms skills, comprising the steps of: sequentially displaying stimuli of a first plurality of visual stimuli, the first plurality of visual stimuli having an initial stimulus, intervening stimuli, and a final stimulus, each stimulus in the first plurality of visual stimuli having at least one of: a speed of movement greater than the speed of movement of an immediately preceding stimulus, and a time period of display shorter than the time period of display of an immediately preceding stimulus; determining the trainee's success in at least one of sighting, tracking, recognizing, and shooting each of the first plurality of visual stimuli while displayed; ceasing display of the first plurality of visual stimuli upon the trainee's success declining below a predetermined threshold, the final stimulus being the last displayed stimulus upon ceasing display; sequentially displaying stimuli of a second plurality of visual stimuli, each stimulus of the second plurality of visual stimuli having at least one of: a speed of movement exceeding the speed of movement for the final stimulus, and a time period of display shorter than the time period of display for the final stimulus; sequentially displaying stimuli of a third plurality of visual stimuli, each stimulus of the third plurality of visual stimuli having at least one of: a speed of movement less than the speed of movement for the final stimulus and greater than the speed of movement for the initial stimulus, and a time period of display longer than the time period of display for the final stimulus and shorter than the time period of display for the initial stimulus; and wherein the trainee attempts to at least one of sight, track, recognize, and shoot each stimulus of the first, second, and third plurality of visual stimuli.
