Demonstrations of change blindness May 31, 2006

As we discussed in class, the Visual Cognition Lab at the University of Illinois has done a number of experiments on change blindness, and has posted some of their stimulus videos.  Try out this video, first not attempting to find changes, and then again with a focus on changes.

These kinds of video-based changes are quite common, and there are even people who watch for them in popular television series. See, for example, this site for Star Trek and X-Files includes such changes under "continuity and production problems."

The reading schedule has been updated, and now goes to mid-July. There will probably be one or two more updates before I'm finished with it, but this should give you a much better idea of where we're going.

There was a question about office hours. As I mentioned in class, they are 1:30-3:00 pm Wednesdays. My office is in Tech Square at 220 TSRB. I'll update the syllabus soon, once we get the office hours from the TAs.

I posted them last night. Just check out the lecture titles in the Reading Schedule page. The lectures are given in PDF format.

Right now, the lectures are about large (around 2M each), probably because the background image we're using. We're looking into reducing the size for those of you without high-speed connections.

I've updated the readings page to add the textbook description and to make the readings clearer.

Flipper was only his stage name… May 18, 2006

As we discussed in class, researchers in Scotland have shown that dolphins use whistle sequences that act as their unique identifiers — in other words, they appear to name themselves. They are the only animals (aside from parrots) known to have this behavior.
