New mothers are more attracted to the body odor of newborn infants than are nonmothers. In this study we investigated the relation of postpartum hormones and of prior experience with infants to this enhanced maternal attraction to infant odors. New mothers were asked to complete a hedonics task, using a pleasantness scale to provide an attraction score to(More)
To determine the responsiveness of new fathers and non-fathers toward infant cues, we exposed fathers and non-fathers to infant cries and to control stimuli and we measured affective, heart-rate, and endocrine responses, including salivary testosterone and cortisol and plasma prolactin concentrations prior to and after cry presentations. We found that (1)(More)
The present study examined the effects of a postpartum Social Support Group intervention on mood state, attitudes and behavior of new mothers. Intervention conditions consisted of an eight session Social Support intervention (n = 44), a no intervention condition (n = 83) and a Group-by-Mail intervention (n = 15). Attitudinal and behavioral assessments were(More)
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)
In this article we review some of the hormonal, sensory and experiential factors that regulate the onset and early maintenance of maternal responsiveness in rat and human mothers. We discuss data suggesting that, in humans, pregnancy is associated with changes in feelings and attitudes that may bear on adjustment to motherhood postpartum. Preliminary(More)
Home observations were done on sibling interactions in 31 families with a child having Down's syndrome and a non-handicapped sibling. The siblings with Down's syndrome initiated less prosocial and agonistic behaviour, but imitated more frequently than their non-handicapped siblings. These effects were found regardless of birth order. There were no effects(More)
In an attempt to develop objective criteria for the process of mother-child bonding, 18 premature infants with a birth weight of less than 1,501 gm were regularly observed alone and together with their mothers during each nursery visit and three home visits, one, two, and three months after discharge from the hospital. Results indicate that (1) mothers(More)
Hedonic responses to a variety of infant (general body, urine, and feces) and noninfant (lotion, cheese, and spice) odorants were compared in four groups of subjects: new mothers, mothers a 1-month postpartum, and female and male nonparents. Using standard scaling procedures, subjects rated each of the odorants twice on a scale from extremely unpleasant(More)
This paper describes methods of measuring a preference a mother develops for one twin over the other and describes the effect such preference has on the intellectual functioning and behavior of 24 twin pairs over 4 years. Results indicate that the majority of mothers develops a preference for one premature twin within 2 weeks after birth and maintains this(More)
The psychiatric, psychological, school and overall family functioning of 64 very small premature infants was assessed from birth up to 48 mnths of age. Results indicated that 43% of infants scored in the abnormal range on a behaviour rating scale filled in by the mothers and 24% on a teacher rating scale at age 4. However, only 11% of the children received(More)
