In response to these findings, Buetti & Lleras (in preparation) developed a model of visual search, the Information Theory of Vision (ITV). ITV uniquely proposes that the time it takes to perform the initial stage of visual search, during which likely non-targets (lures) are separated from possible targets (candidates), will increase with the amount of information present in the display.
