Example for the visual search array with a vertically oriented target defined in the shape dimension. Search arrays consisted of 8 stimuli in a circular array against a black background, each presented equidistant from a white central fixation cross. Distractors were blue circles and targets were defined in the color dimension (red) or shape dimension (square). Each stimulus was either horizontally or vertically oriented. Participants were asked to discriminate the orientation of the singleton target as fast and accurately as possible.
