Border Collie Comprehends over 1000 Object Names as Verbal Referents

Here's an absolutely fascinating article about research with a Border Collie called Chaser, who can recognize the noun names for 1022 objects. The researchers only stopped at 1022 because of time constraints, not because they had reached the limit of Chaser's cognition. Much more importantly, tests revealed that Chaser understood the nouns as proper referents to each of her toys and did not mis-interpret them as commands. She showed an ability to combine toy names with a range of commands - and behaved accordingly. She was also capable of grouping her 1022 toys according to categories.
