Reaction: Attention and Visual Memory in Visualization and Computer Graphics

The detailed discussion of preattentive processing is appreciated. It sounds like there is still a little bit of work to do in understanding the inner-workings of the mind that allow preattentive processing, but the outward effects are pretty well understood. I think the theory that search ability varies continuously and depends on the type of task and display conditions makes the most intuitive sense. As for the other effects, post-attentive amnesia and change blindness are two that I'd read about before and the discussion is very interesting in contrast to preattentive processing. The final focus on predicting attention and directing attention looks like something I would like to dive into a little more. Predicting attention may not be as important now if you're using it to lower rendering costs, since rendering speeds are increasing rapidly, but it could help to maximize the effect of a visualization. All in all this is a very interesting paper.
