A Spurious Pop-Out in Visual Search.
Abstract
The present study demonstrates that an object embedded in an array of identical objects can pop-out. Dependent on the stimuli preceding the search display, local (chromatic) adaptation causes an identical object to pop-out because it appears to have a color (Experiment 1) or brightness (Experiment 2) that is slightly different from the color and brightness of the other objects in the display. Experiment 3 shows that this pop-out even occurs when the stimulus preceding the search display is presented for 100 Ms. The present findings have severe implications on the design of experiments in which no eye movements are allowed involving multiple displays presented in successive order. Reaction Time, Search, Vision.
