Evolutionary considerations (cf. MacDonald, 1992) suggest that emotional cl
oseness and security of attachment address different functional systems. We
assume that maternal sensitivity during early face-to-face interactions is
related to later emotional closeness, whereas the contingency of maternal
reactions towards the infant's signals is related to later security of atta
chment. Forty-three mother-infant dyads were videotaped at home during face
-to-face interactions when the infants were 3 months old, and were seen in
the strange situation when the infants were 12 months old. Results confirm
the assumptions, with significant correlations between early face-to-face s
ensitivity and later contact seeking, maintaining, and avoiding behaviour o
f the infant during the reunion episodes of the strange situation. Early ma
ternal face-to-face contingency was related to later security of attachment
.
