Sample Single-target Display, Dual-target Display, and Hit Rate Graph for an SSM task: In a standard cognitive science SSM task, observers are asked to search in simplified-search displays for ‘T’ shaped targets (where the crossbars of the two perpendicular rectangles perfectly bisect one another) amongst pseudo ‘L’ shaped distractors (two perpendicular rectangles do not perfectly bisect one another). Search items are typically randomized for rotation (e.g., 0, 90, 180, or 270 from a canonical ‘T’ shape) and location within the search display. Search items may also vary in “salience” (e.g., a darker gray or light gray color amongst a white background), which allows researchers to compare the hit rate of a specific type of target (e.g., low-salience ‘T’) between single and dual-target displays to calculate the SSM effect. The graph above depicts a typical SSM effect with a lower hit rate for a low-salience ‘T’ when it appeared in a dual-target display compared to when a low-salience ‘T’ appeared in a single-target display. These hypothetical results suggest that the detection of the low-salience target ‘T’ was affected by the detection of the high-salience target ‘T’ compared to when it was by itself in a search display (e.g., Fleck et al., 2010)
