A 3-yr-old hearing-impaired girl, who used neither the article "the" nor the auxiliary verb "is" was taught to use these words in describing a picture, initially through imitation and then in response to the command, "Tell me about this". As a result, she was able to use sentences in the present progressive form to describe a number of pictures on which she had received no training. This newly acquired behavior was subsequently extinguished and then reinstated.
一位 3 岁失聪女孩,既不使用冠词“the”也不用助动词“is”,我们通过模仿以及在“告诉我这是什么”的指令下教会她使用这些词来描述图片。结果,她能够用现在进行时态的句子来描述一些她没有接受过训练的图片。新习得的行为随后被消退和重新建立。
