Abstract

Objectives: The current study examined whether early receptive and expressive vocabulary development is related with children's socioeconomic background by analyzing longitudinal data of Korean children at 3 and 7 years of age. Methods: In general, both vocabulary scores were about 2.5 times higher at 7 years than at 3 years. Socioeconomic background was significantly associated with expressive vocabulary development at age 3, and with the amount of change in the receptive scores between the ages of 3 and 7. While this relationship was maintained in the expressive scores of the 7-year-old, for lower income families the first child tended to develop relatively slowly while the third child developed the quickest. In addition, the results showed that girls' scores tended to be higher than boys' scores at 3-year-old, and the difference was maintained in all other scores. Results: There were effects of household income and birth order which interacted. The birth order effect pattern was very similar to the effect of household income. Conclusion: The results are discussed in comparison with previous Korean findings and with international ones.
