He gave emphasis on the importance of reinforcement in language acquisition. He gave one of the earliest scientific explanations of language acquisition in 1957. He accounted for language development using the influence of the environment. He made an argument that children learn language on behaviorist reinforcement principles through the connection of words with meanings. According to him, correct utterances are reinforced once the child realizes the value of words and phrases.
