“Chase the target”
The Chase test measures visual motor control using a “chase the target” paradigm. This test is usually presented immediately before the Groton Maze Learning Test to familiarize the participant with the grid and to gain a measure of visuo-motor speed.
The Chase test uses the same size grid as the Groton Maze Learning Test (e.g., a 10 x 10 grid of tiles). A red target is presented in the top left tile; the participant must select this target to begin the test. The target will move randomly from tile to tile throughout the grid and the participant must chase it by selecting tiles one at a time. If the correct move is made, a green checkmark briefly appears. If the move is incorrect, a red cross is briefly revealed.
