Exposure to number talk in infancy predicts later mathematic skills

Area of Science:

• Child Development
• Developmental Psychology
• Early Childhood Education

Background:

• Early language exposure significantly impacts school readiness.
• Variability in children's early math language experiences is substantial.
• Number word exposure in infancy may predict later math skills.

Purpose of the Study:

• To investigate mothers' longitudinal use of number words with infants.
• To examine the association between early number word exposure and later math/pre-literacy skills.
• To analyze these associations across diverse racial, ethnic, and linguistic groups.

Main Methods:

• Longitudinal study of mother-child dyads (US Dominican, Mexican, African American).
• Analysis of mothers' use of number words with 1- and 2-year-olds.
• Assessment of children's math and pre-literacy skills in preschool (at 4 years).

Main Results:

• Mothers' use of number words varied significantly and stably over time.
• Infant exposure to number words predicted children's math skills at age 4.
• No significant association was found with pre-literacy skills.

Conclusions:

• Early exposure to number words is crucial for developing foundational math skills.
• Caregiver talk about numbers, even before children understand, is important.
• This highlights the significance of early language environments for math development.
