Visual Search

An square array of symbols appears on the screen. For each screen the testee locates the target, which is an L shape in any orientation, and taps on it a s quickly as possible. Non-target shapes can either be X (as shown on the right, in which case the target “pops out”, and search is parallel, and almost independent of array size) or T, in which case search is serial, and increases with array size).
