The reaction times were initially guesses, but have been refined from real-world, empirical feedback from working with kids in the program and through a pilot study done at a local school. Initially, we found that targets were disappearing from the screen too quickly for the majority of students so the target time frames were adjusted to allow more time. After adjustments, the average child did have enough time to respond to the targets. Of course, there are still outliers in that some children were still unable to reach those targets, but further training should improve those times, and reaction and processing speed are integral components to the system.
The reaction speeds cannot be manually adjusted at this time.
