I've been waiting to post this until I could link to it online, but that may take a while yet. In the September 21, 2007 issue of Science, I have a news feature on the newest research in slips of the tongue & hand, including the first report of comparative cognitive scientist Heidi Lyn's analysis of errors made by Kanzi and Panbanisha, the bonobos, in vocabulary tests.

It's first time in 30 years that ape language research has made it into Science, Lyn told me.

Update: I was going to summarize Lyn's study, but then I found an upload of the article here .
