2 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  , R346-R349DOI: ( /j.cub ) Copyright © 2010 Elsevier Ltd Terms and Conditions

3 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.

6 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. Current Biology  , R346-R349DOI: ( /j.cub ) Copyright © 2010 Elsevier Ltd Terms and Conditions
