Skill enhancement tool for assessing and improving an individual's
performance in multiple domains including processing of complex audio,
visual and tactile perceptual inputs, operation of complex controls via
manipulation, enacting complex motor sequences and complex cognitive
tasks. The invention presents complex stimuli to an individual, monitors
his or her reactions to the stimuli, and, in response to the user's
reactions, changes the future stimuli to be presented in such a way as to
alter the user's brain entrainment patterns to elicit improvement.
