Early mother-infant interaction and later security of attachment were assessed for 17 pairs of twins, 5 singleton survivors of twin pairs, and 20 singletons, all low-birth-weight preterm infants. Mother and infant behavior during home observations at 6 weeks and 3, 6, and 9 months was rated on scales developed by Ainsworth and Egeland and Brunquell. A, B,(More)

Subsequently, during a 10-sec recognition trial infants were presented with the(More)
40 10-month-old infants were given 2 min to explore tactually an object in a totally darkened room. Subsequently, during a 2-min test trial in the dark, half of the infants were given the same object and half were given a novel shape. Infants presented with the novel shape evidenced significantly longer durations of manipulation than infants presented with(More)
