Nevertheless, a parallel process for color detection can differentiate between green and red items supporting search efficiency. , 1989); ii) the locations of the green items are 'suppressed' (Treisman and Sato, 1990). , 1989) found a wide variation in performance between subjects. This suggests that there might be some factor that varies from individual to individual that could lead to a conjunction search with evident positive slope (serial conjunction search) or to a conjunction search with an almost flat slope (parallel conjunction search).

Selective attention exploits a trade-off between resolution and spatial extent: the same channel can be activated to attend to a large visual area with low resolution or to a small visual area with fine resolution. This trade off is needed because of the limited amount of information that attentional mechanism for high-level processing can select. For example, the particular pattern to be recognized relies on the observer's judgment and in most cases different judgments lead to different spatial resolutions.
