Developmental Changes in Mental Performance: The Effect of the Birth of a Sibling.
McCall, Robert B.
Child Development, v55 n4 p1317-21 Aug 1984
The IQ performance of children who experienced the birth of a younger sibling was found to drop 10 points during the next two years for singleton children and 5.8 points for last-born children from families of comparable size. The study controlled for sex, family size, age at assessment, and IQ before the birth of the sibling. (Author/RH)
