Children in foster care have higher intelligence than those raised in institutions

Newly published research in the journal Science confirms that institutionalized orphans placed into foster care have much better intellectual development than those who remain behind. The authors say the results have implications for countries "grappling with how best to care for abandoned, orphaned and maltreated young children."

A team of researchers including Nathan Fox, a professor of human development (College of Education) at the University of Maryland, has been studying a randomly chosen group of 136 abandoned children from six institutions in Bucharest, Romania for a number of years. The Bucharest Early Intervention Project (BEIP) tracked the children out to 54 months of age.

Also involved in the study are Charles Nelson of Harvard University ; Dr. Charles Zeanah and Anna Smyke of Tulane University , and Peter Marshall of Temple University. The research was supported by the MacArthur Foundation Research Network on "Early Experience and Brain Development."

The Importance of Early Intervention

Earlier evidence from the intervention project showed that young children who remain institutionalized suffered intellectual, emotional, psychiatric and brain development problems. Prof. Fox says, "They are deprived of typical social and emotional stimulation and interaction, as well as typical cognitive and language stimulation." Knowing this, the primary question researchers had was, is there a "best time" when intervention can help prevent these children from becoming psychologically deprived -- when damage can be prevented. The Bucharest Early Intervention Project was designed to look at this issue of timing as it related to early deprivation.

The study accomplished this by randomly assigning children into two groups of children that were abandoned at or shortly after birth. "Children at the time of entry into the study ranged in age from 6-29 months of age," says Fox.
