Area of Research for a Ph.D. Student?

Here's an interesting experiment summarized in the New Scientist. By tracking eye movements, the study's authors presented new objects in areas that were not being attended to. The relevance to FPS video games is obvious, but this approach also gives us a way to study how we allocate attention.

Maybe this will inspire some of you in the lab to think of experiments that could form the basis of a thesis ... The New Scientist article gives a link to the authors' website at McGill where you can find the articles.
