Early mother-infant interaction during breast- and bottle-feeding

Thirty-two primiparous mothers with their neonates, 20 breast-fed and 12 bottle-fed, were videotaped during feeding longitudinally (at 3, 10 days, 1 and 3 months) in order to investigate whether patterns of mother-infant interaction observed during breast- and bottle-feeding differ also for behavior not directly related to sucking. Infant state, sucking behavior, mother behavior and mother-infant interaction were analyzed by both sequential and non sequential analysis. Results suggest that the method of feedings affects mother-infant interaction observed during and just after feeding also for some behavior not directly related to sucking. The percentage of mutual touch, tactile stimulation and mother's gaze to infant was significantly more elevated during breast-feeding. Independently of the feeding mode, significant sequential dependencies between infant state of alertness and auditory stimulation, and auditory stimulation and mutual gaze were found.     

The psychobiology of parenting in mammals

Parental behavior denotes a vareity of genetically programmed activities in which parents help their young to survive to maturity. A highly successful research has been devoted to the psychoneuroendocrine bases of parenting in two species, rat and sheep. As a result empirical data along with conceptual formulations have been obtained which provide a model for generating hypothesis for the study of other species. This review was written to draw the attention to this research because of its enormous potential significance for problems pertaining to human infant care. It discusses the current status of research on the physiological bases of parental behavior,     

Infant food refusal and parental social support

The purpose of this study was to examine the relations between various aspects of social support and maternal and infant outcome variables in a group of families having infants showing food refusal compared to a control group. In the case of early food refusal, the results indicated that access to emotional support and satisfaction with support were related to maternal psychosomatic health. The relationships were interpreted as showing that social support has moderating effects on negative outcomes of food refusal.     

Infant–mother social referencing interactions: Description and antecedents in maternal sensitivity and infant irritability

The purpose of the study was to describe naturally occurring infant and maternal behaviours in terms of social referencing in a stranger wariness situation, and to explore antecedents to such behaviouts in early maternal sensitivity and infant irritability. One hundred and ten 10-months-old infants and their mothers were videotaped. Infant social referencing behaviour was defined as puzzled looks directed at mother's face after the infant had discovered the stranger. Almost half of the infants looked with a puzzled expression at their mothers immediately after discovering the stranger, and a majority of the mothers sent a positive message back to the infants. Twenty per cent of the infants never looked at their mothers and 20% of the mothers did not respond when their infants turned to them. Infants whose mothers had responded positively to the referencing look showed positive responses to the stranger to a higher degree than infants who did not reference or those who were not responded to. Antecedents to infant and mother interactive behaviours were sought in maternal sensitivity (general sensitivity, physical contact, responsiveness, intrusiveness, response to distress, and effectiveness in comforting) and in infant irritability as observed when the infants were 4 months old. It was found that infants who did not reference their mothers for information at 10 months had experienced less sensitive mothering 6 months earlier and had also shown more irritability.     

Effects of maternal employment patterns on adolescents' substance use and other risk-taking behaviors

Employment for mothers with school-age children has generated great concern regarding its possible harmful effects on adolescents and their families. We examined the influence of maternal employment on the risk-taking behavior of adolescents in two-parent families. Three hundred and eighty-nine high school students completed a 48-item survey in which they indicated their mother's and father's employment patterns, and their own risk-taking behaviors (e.g., substance use, driving while under the influence). Results showed no significant effects of maternal employment on adolescent risk-taking behaviors.     

Do maternal power assertive discipline and warmth interact to influence toddlers' emotional reactivity and noncompliance?

Emotional and behavioural self-regulation emerges during infancy and toddlerhood and is heavily influenced by parenting. Parents facilitate toddlers' behavioural regulation (e.g., compliance) by using appropriate control with warmth and managing children's emotional reactivity during situational demands. In contrast, power assertive discipline may strain children's regulatory skills, for example by evoking toddlers' negative affect. However, we have more to learn about how discipline relates to toddlers' self-regulation in the moment and whether concurrent displays of parental warmth may moderate these relations. Mother–toddler dyads (N = 74, M_age = 13.30 months) from low-to-middle income Turkish families participated in a 3-min laboratory task, in which toddlers needed to delay playing with an attractive toy. Maternal discipline, warmth, toddler's emotional reactivity, and noncompliance were coded from observations. Results showed that higher power assertive discipline was associated with more frequent emotional reactivity in toddlers whose mothers' showed warmth during the <84% of the task duration. Maternal warmth was negatively associated with child noncompliance, but warmth did not interact with power assertive discipline in relation to noncompliance. Results suggest that observed power assertive discipline is meaningfully related to toddlers' emotional reactivity and higher levels of expressed maternal warmth attenuates these relations.     

Relationship between maternal aggression and maternal care in the rat

Aggression among female rats is almost entirely confined to the period of late pregnancy and lactation. Behaviorally it is similar to the aggression of males including piloerection and lateral attacks, but it differs in its function. Unlike male aggression which serves to establish a social hierarchy and a territory, i. e., is competitive, maternal aggression is protective, i. e., it serves to prevent predation of the mother's offspring. In this respect it is closely related temporally and causally to maternal care; if the offspring are removed maternal aggression wanes almost immediately–its function no longer exists! Studies on aggression by mothers, among rats, from the author's laboratory are reviewed and comparisons made with maternal care. As noted, maternal aggression and maternal care are closely related during the cycle of maternal behavior and they share a similar hormonal basis and possibly the effect of uterine stimulation, but maternal care requires prolactin and the decline of progesterone while maternal aggression appears independent of pituitary hormones and does not require a decline in progesterone. Maternal aggression like maternal care appears to be organized into a hormonal phase, during pregnancy, parturition, and for about a week postpartum and a nonhormonal phase thereafter. Bilateral radiofrequency lesions of the lateral midbrain peripeduncular nucleus (PPN) produce deficits in maternal aggression if made on lactation day 7 (L7), but not earlier, without producing significant deficits in maternal behavior. Experiments showed that the PPN does not mediate hormonally stimulated maternal aggression; it appears to mediate only nonhormonally stimulated maternal aggression. Studies on the role of pregnancy hormones on long-term retention of maternal aggression and the role of olfaction in maternal aggression are also reviewed. © 1994 Wiley-Liss, Inc.     

Responsive Parenting in the Second Year: Specific Influences on Children's Language and Play

In two longitudinal studies, relations between dimensions of maternal responsiveness at 13 months and children's language and play abilities at 13 and at 20 months were examined. We characterized mothers' responsive exchanges by assessing the targets of maternal responses (i.e. what child activities mothers respond to) and the verbal contents of maternal responses (i.e. what mothers said when they responded), and we asked whether subtypes of responsiveness would relate differentially to children's language and play abilities. In general, maternal responsiveness to children's vocalizations predicted children's language, and maternal responses to children's play predicted children's play. These findings suggest that maternal responsiveness can be profitably categorized into subtypes that relate to domains of child outcomes in specialized ways. The specific nature of mother–child associations in the domains of early language and play is discussed. © 1996 John Wiley & Sons, Ltd.
