Administration Time (in healthy volunteers): 0.5 Minutes
Cognitive Domain Usually Measured: Visual Motor Function
Task Description:
The aim of this task is to introduce the subject to the rules of the Groton Maze tasks.
The pre-task on-screen instructions state: "Chase the Target". The test supervisor will read the full task instructions to the subject. To begin the task, the test supervisor or subject must press the "Enter" key. The subject will first complete a practice test.
The subject is shown a 10 x 10 grid of tiles on a computer touch screen.
The subject is asked to tap the blue tile in the top left corner of the grid with the stylus pen. As the target moves, the subject ‘chases' it by tapping on the tiles one at a time. The subject cannot move diagonally and cannot skip a tile. If the subject makes a mistake, they must go back to the last correct tile.
The subject should be encouraged to move as quickly and accurately as possible. Once the test supervisor judges that the subject understands the rules, the subject is instructed to click on the "Finish" button in the upper left corner of the screen.
The subject is then asked to repeat the same task for a timed period of 30 seconds. The same rules apply as in the practice. The subject chases the target until the task stops.
Primary Outcome measures:
Unit of measurement: Moves per second
Description and interpretation of scores: The total number of correct moves made per second. (Higher score = better performance)
