【 摘 要 】

Electronic displays such as geophysical maps can become heavily cluttered (e.g. Lohrenz, Trafton, Beck, & Gendron, 2009), hindering operators’ accurate detection of task-critical information. The use of visual search asymmetries (Treisman & Souther, 1985) in the design of display iconography might be an effective technique for prioritizing important information in such displays, but only if the asymmetry persists in the presence of clutter. The present experiments demonstrate that search asymmetries based on an additional feature (Treisman & Souther, 1985) and on stimulus familiarity (Malinowski & Hübner, 2001) persisted across varying levels of visual clutter. Results imply that iconography exploiting visual search asymmetries can support efficient search even in heavily cluttered displays.
