Penn psychologists show that quality matters more than quantity for word learning

A new study by psychologists at the University of Pennsylvania now shows that early vocabulary improvement is likely to have 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. Moreover, the study shows that, unlike quantity, the quality of these interactions is not related to the parents' socioeconomic status.
