Early vocabulary improvement has more to do with the quality of the interactions in which the words are used rather than the sheer quantity of speech directed at young children.

The study was conducted by professors John Trueswell and Lila Gleitman, both of the Department of Psychology in Penn's School of Arts and Sciences, as well as by Erica Cartmill and Susan Goldin-Meadow of the University of Chicago. Also contributing to the study were Benjamin Armstrong III of Penn and Tamara Medina of Drexel University.
Knowing how critical early-language acquisition is to a person's future success, Trueswell and Gleitman have long investigated the mechanisms involved in how children learn their first words.
One of their previous studies suggests that children learn these words in what might be described as a "eureka" moment - that is, only after "highly informative" examples of speech that clearly connect the word to the thing it refers to.
The researchers suspected these highly informative examples would matter much more than the sheer amount of talk in the home when it came to which children learned more words.
To determine if this was the case, they set out to track the long-term effects of these examples, seeing if children who had been exposed to them more often did better on a vocabulary test three years later. However, to begin this study, the researchers first had to determine what constituted highly informative speech.

They made these visits when the children were 14 months old and then again four months later.

The effect of this discrepancy was clear when the researchers tracked how well each of the children did on a standard vocabulary test three years later.
The more frequently a child heard highly informative examples of speech, the better he or she did on these tests.
The study is published in the Proceedings of the National Academy of Sciences.
