An article in the NY Times today tells the story of Chaser (above), a border Collie in Spartanburg, SC that knows 1,022 nouns. She was taught the words by a retired psychology professor, John W. Pilley, who worked with her up to five hours a day. When he got tired of teaching nouns, they moved on to grammar!
What is perhaps most interesting about this story is that the journal Behavioural Processes has accepted Prof. Pilley’s article on his experimentation with Chaser, believing that the work was not tainted by a Clever Hans effect. If you don’t know the story of this famous horse (below, being clever), check it out here–it’s definitely worth the read.
