Figure 1 Search for the King of Diamonds. Even though you can see all the cards, you need to search for the target. You probably do not spend much time on the black cards. Current Biology 2010 20, R346-R349DOI: (10.1016/j.cub.2010.02.016) Copyright © 2010 Elsevier Ltd Terms and Conditions

Figure 2 Attention and visual search. Your attention is probably drawn to the big, irregular yellow item in a bottom-up, stimulus driven manner. With no change in the visual stimulation, you can easily reconfigure your attention to favor ‘blue ovals’ in a ‘top-down’ user-driven manner.

Figure 4 Finding signs of cancer in a mammogram can be a difficult visual search task, even for experts. Current Biology 2010 20, R346-R349DOI: (10.1016/j.cub.2010.02.016) Copyright © 2010 Elsevier Ltd Terms and Conditions

Figure 5 Timescale of visual search. The timescale of typical search tasks runs from fractions of a second to many minutes or more. Most laboratory research has been concentrated at the shorter end of this spectrum.
