US dog learns more than 1,000 words
US: She just might be the smartest pooch ever. A border collie has
learned more than 1,000 words, showing US researchers that her memory is
not only better than theirs, but that she understands quite a bit about
how language works.
Chaser learned the names for 1,022 toys, so many that her human
handlers had to write on them in marker so that they wouldn’t forget,
said study co-author Alliston Reid, a psychology professor at Wofford
College in South Carolina.
With that repertoire, Chaser has far outpaced another dog, Rico,
found by German researchers to be able to grasp about 200 words,
according to a study published in 2004 in the journal Science.
As a border collie, Chaser comes from a breed of herding dog known
for its intelligence, energy and strong work ethic.
Reid said she might be able to learn even more words, but her keepers
stopped at 1,022 after three years of training simply because of time
constraints.
But identifying objects by name was just the beginning of the
research, conducted by a pair of American psychology professors who
became curious about the upper limits of a dog’s learning abilities
after seeing the German study.
Study co-author John Pilley was also a master animal trainer and just
happened to be getting a young border collie as a pet at about the same
time as the research on Rico came out.
By the time the pup was five months old, language training began in
earnest.
“John Pilley and I would go to second-hand stores and just buy huge
numbers of stuffed animals and balls and children’s toys and so forth,”
said Reid.
