In one trial, researchers tested their "partial-mapping preparation" hypothesis by having 18 undergraduates view four boxes in a two-by-two grid on a monitor. A colored shape, such as a red triangle, would appear in one box for four seconds. Participants had to press one of three computer keys that corresponded with either the object's color (red, green or blue) or shape (diamond, square or triangle). Participants used the same three keys for both object and color tests.
