Recent studies show that visual search often involves a combination of both parallel and serial search strategies. Consequently, computational models and theoretical accounts of visual search processing have evolved from traditional parallel or serial descriptions to a continuum from "efficient" to "inefficient." In our first experiments (1a & 1b), we demonstrate with various conditions that search efficiency does not increase with simultaneous delivery of target features in a

We find a facilitatory effect when non-linguistic visual delivery of target features is concurrent with the visual display onset, but not when the target features are delivered prior to display onset. The results support an interactive account of visual perception that explains linguistic and non-linguistic mediation of visual search as chiefly due to the incrementality of target feature delivery once search has begun.
