For this study typically developing 5- to 12-year-old children will play a computer game by moving a robotic arm to colored targets presented on a computer monitor. This game is similar to connect-the-dots and will take about 1 - 1.5 hours to complete. Children will receive $10 for their participation.

Brad gives the child instructions on how to use the robot arm (like a big joystick) to move the computer cursor from one target to another on the screen.

The goggles prevent the child from seeing where his arm is during the computer game.
