Research has shown that most 18-month-olds learn an average of two to five new words a day; however, little is known about how children process information to learn new words as they move through the preschool years. In a new study, a University of Missouri researcher has found that toddlers learn words differently as they age, and a limit exists as to how many words they can learn each day. These findings could help parents enhance their children’s vocabularies and assist speech-language professionals in developing and refining interventions to help children with language delays.
“We found that babies’ abilities to accurately guess the meaning of new words increases between 18 and 30 months of age, and by 24 to 36 months, toddlers are able to accurately guess the meanings of new words at a significantly higher level,” said Judith Goodman, an associate professor in the MU School of Health Professions and chair of the Department of Communication Science and Disorders. “Interestingly, we observed that even from the time children mature from 18 to 30 months of age, the cues toddlers use to learn new words change.”
