Profile: Gordon Systems, Inc. offer assessment, tracking tools and treatment protocols for clinicians & physicians concerning the diagnosis and treatment of ADD/ADHD. Our gordon diagnostic system aids in the diagnosis of attention deficits, especially attention deficit hyperactivity disorder. It provides objective information about an individual's ability to sustain attention and exert self-control. We produce vigilance task that yields data regarding an individual ability to focus and maintain attention over time and in the absence of feedback. It records the number of correct responses, incorrect responses, and failures to respond to the 1/9 combination. It processes parallel forms of each task and a test of impulse control, which requires a child to inhibit responding. We supply internal microprocessor that generates the tasks and records quantitative features of the child performance.
