Any particular time? I guess the most relevant time for this question is early half of 20th century.

Answer:
B.F Skinner´s studies led him to the idea that children learn language through operant conditioning. Applying positive reinforcement when a child uses a word correctly helps him to learn the association between that word and its meanings.
Explanation:
Celebrating a child for producing sounds that are close to a word reassures him and makes him repeat it. On the other hand, ignoring sounds that aren´t similar to any words makes the child forget about them. Based on his theory, Skinner developed a teaching process for language development based on the reinforcement of correct use of language. Let's imagine a child that says the word "milk" or a sound similar to that word. If he´s given milk after that and praised about it, he will learn the relationship between the word and its meaning and develop a language based on that information.
