Working Memory

An interesting study from UC Davis reaffirms that people can only remember 2-4 things from every quarter-second "frame" they see. Basically, if you are shown a picture for a quarter second, you might be able to remember only 4 things from that picture.

News like this always reminds me that we need to keep game HUDs simple and uncluttered, allowing players to get the information they really need without mistakenly soaking in data that they don't. Too much visual information can result in confusion.
