テーマ：「Parental caring differences and the vocabulary development of Vietnamese preschool children: Evidence from the Young Lives survey」
Using the Young Lives survey from the University of Oxford that tracked Vietnamese millennium-born children over a 15-year period, we investigate whether the time spent by blood-parents with their child could be associated with language development during the 4–8 years of age period. We applied first-differencing between the two ages for complete control of time-invariant factors. We find mothers who looked after their children daily contributed an increase equivalent to 39.7 percent of one standard deviation of the community standardized Peabody Picture Vocabulary Test (PPVT) scores. Mothers without a high school diploma are more likely to dedicate more time to a son, especially the eldest, resulting in better language development. In contrast, the frequency of time spent with fathers does not show any statistically significant connection with the PPVT scores of the children regardless of household composition. We also find schooling and sufficient nutrition are important to language development.
