14.The more scientists study pigeons,the more they learn how their brains operate in ways not so different from our own.In a new study,researchers found that pigeons can categorize and name both natural and man-made objects-and not just a few objects.These birds categorized 128 photographs into 16categories.
Ed Wasserman,an author of the study,says the finding suggests a similarity between how pigeons learn the equivalent of words and the way children do.
In an experiment the researchers used a computerized version of the"name game"where three pigeons were shown 128 black-and-white photos of objects from 16 basic categories:baby,bottle,cake,car,cracker,dog,duck,fish,flower,hat,key,pen,phone,plane,shoe,tree.They then had to peck(啄) on one of two different symbols:the correct one for that photo and an incorrect one that was randomly chosen from one of the remaining 15 categories.The pigeons not only succeeded in learning the task,but they reliably transferred the learning to four new photos from each of the 16 categories.
Pigeons have long been known to be smarter than average birds.They have a"homing instinct(返巢本能)"that helps them find their way home,even when blindfolded(蒙住眼睛).They have better eyesight than humans and have been trained to spot orange life jackets of people lost at sea.They carried messages for the U.S.Army during the two world wars.
McMurray,another author of the study,says"Our testing methods can be used with any type of animal that can interact with a computer screen."
He also says,"Contrary to people's belief,the research shows the methods with which children solve this huge problem may be shared with many species."
Wasserman acknowledges though this study is not a direct equivalent of word learning in children,the model used in the study could lead to a better understanding of children's word learning.
