Sex differences in infant-mother attachment.Psychol Rep. 2003 Feb; 92(1):84-8.PR
A sex difference in security of infant attachment was found in a sample of 52 infant-mother dyads. The infants were enrolled in early care and education programs within a predominantly small-town geographic area in the southwest. Security of attachment was assessed using the Strange Situation procedure. Male infants (76%) were significantly more likely to be securely attached than female infants (39%). No other variables related to the infants' early care and education experience or mothers' age, race, marital status, and education were significantly associated with infants' attachment status.
