All of the Following Are Claims of the Behaviorist Approach

All of the following are claims of the behaviorist approach to language learning EXCEPT:

B) parents should respond more positively to babbles that resemble adult speech sound and more negatively to those that do not
C) parents should respond more positively as children utter strings of words that come closer and closer to adult grammatical patterns
D) bilingual and even trilingual children should acquire all their languages together at about the same time as monolingual children
