Project on Human Development in Chicago Neighborhoods (PHDCN) Series

As part of the Longitudinal Cohort Study, 412 infants from the birth cohort and their primary caregivers were studied during wave 1 (1994-1997) to examine the effects of prenatal and postnatal conditions on the health and cognitive functioning of infants in the first year of life. The Infant Assessment Unit also sought to link early developmental processes and the onset of antisocial behavior and to measure the strength of these relationships. The infants received an assessment between the ages of 5 to 7 months, in addition to the protocol given to all infants in cohort 0 as part of the Longitudinal Cohort Study. Measures assessed visual recognition and memory, physical health and birth complications, temperament, and family environment. Videotaped records were used to record the response of the infant to different types of stimulation, as well as to capture interactions between the parent and infant to determine empathic responsiveness of the parent, encouragement and guidance, and overall psychopathology.
