What is The MATRIX?


THE MATRIX is a computer program designed to run a visual detection task with child or adult participants. It has been used successfully with participants aged 3 to adult. The program automatically presents participants with matrices of photographs, and requires participants to select a single target among an array of distracters. It should be used in conjunction with a touch-screen display so that participants can find targets and touch them on the screen; alternatively, it can also be used with mouse clicks. The MATRIX runs on java programming and can be used on Mac, PC, and Linux.
