38 12-mo-old infants were seen with their mothers in a strange situation test. On the basis of reunion behavior in this situation, each infant was judged securely attached to the mother, insecurely attached to the mother, or intermediate in security. When the infants were 21 mo, research assistants blind to strange situation behavior rated maternal behavior from videotapes of a mother-child free play session. Mothers of securely attached infants were significantly more sensitive, accepting, and expressive of affect than mothers of insecurely attached infants. Mothers of insecurely attached infants were found to be more angry. (3 ref) (PsycINFO Database Record (c) 2006 APA, all rights reserved). © 1979 American Psychological Association.
