The Natural History of 1008 Infants: Phase III. Final Report.
Jordan, Thomas E.
The longitudinal child development study involved a cohort of 1008 infants, born in 1966 and constituted as a non-random sample in order to include a substantial number of biological risk cases. Simultaneously considered were perinatal biological and social adversity and measures of attainment in three domains (physical, motoric, and cognitive) at the end of the preschool years. Experimental subjects were divided into one of four biological risk groups, based upon whether they had experienced disorders of pregnancy and gestation, disorders of delivery, neonatal disorders, or multiple complications. Subjects were tested at 36, 42, 48, and 54 months for motoric skills, cognitive skills, and physical height and weight. The effects of prenatal, perinatal, neonatal, and multiple complications, and social class in the three domains evaluated at the different ages were summarized in 45 tables. Discussion gave attention to the nature of the deficits present at age 4 years. (KW)
