Other universities participating in the work include the University of California, Irvine; Georgia State University; New York University and the University of Washington. “The majority of early developmental work looking at parent-child behavioral interactions is focused on children and mothers. The researchers will leverage the work of the earlier phase of the study, which includes video recordings of 216 2½- to 3½-year-old children interacting with their fathers and their mothers. Scientists from the four institutions beyond UT Dallas and the University of Georgia will contribute their expertise on children’s language development and family relationships within specific demographic contexts. “Prior studies have shown clear differences in language development between boys and girls by age 3,” Rojas said.
