This article went through some of the major theories regarding human psychophysics. There was a lot of interesting information in the article and it was good to go through the various theories for how and why people see certain things and some of the pitfalls in visualizations. I especially enjoyed learning about preattentive processing and change blindness.
There was a lot of information in the article and I'm curious to see how some of the theories and conclusions could be applied to information visualization development. I was particularly interested in how perceptual blindess can, in some ways, be "taken advantage of" to render graphics with less accuracy, but retain the same information conveyance. I also would like to learn more about why some things cause blindness and others don't, which was mentioned in the article as an area in need of future research.
