Main articles: Affectional bond and Attachment theory In 1958, British developmental psychologist John Bowlby published the ground-breaking paper "the Nature of the Child's Tie to his Mother," in which the precursory concepts of "attachment theory" were developed. This included the development of the concept of the affectional bond, sometimes referred to as the emotional bond, which is based on the universal tendency for humans to attach, i.e. to seek closeness to another person and to feel secure when that person is present. Attachment theory has some of its origins in the observation of and experiments with animals, but is also based on observations of children who had missed typical experiences of adult care. Much of the early research on attachment in humans was done by John Bowlby and his associates. Bowlby proposed that babies have an inbuilt need from birth to make emotional attachments, i.e. bonds, because this increases the chances of survival by ensuring that they receive the care they need.[5][6][7] Bowlby did not describe mutuality in attachment. He stated that attachment by mother was a pathological inversion and described only behaviors of the infant. Many developmental specialists elaborated Bowlby's ethological observations. However, neither Bowlby's proximity seeking (not possible for human infants prior to walking) nor subsequent descriptions of caregiver–infant mutuality with emotional availability and synchrony with emotional modulation include the enduring motivation of attachment into adult life. The enduring motivation is the desire to control a pleasantly surprising transformation that is the route of belief in effectiveness by humans.[citation needed] This motivation accounts for curiosity and intellectual growth of language, mathematics and logic, all of which have an emotional base of security.[8] Maternal bonding Main article: Maternal bond Of all human bonds, the maternal bond (mother–infant relationship) is one of the strongest. The maternal bond begins to develop during pregnancy; following pregnancy, the production of oxytocin during lactation increases parasympathetic activity, thus reducing anxiety and theoretically fostering bonding. It is generally understood that maternal oxytocin circulation can predispose some mammals to show caregiving behavior in response to young of their species. Breastfeeding has been reported to foster the early post-partum maternal bond, via touch, response, and mutual gazing.[9] Extensive claims for the effect of breastfeeding were made in the 1930s by Margaret Ribble, a champion of "infant rights,"[10] but were challenged by others.[11] The claimed effect is not universal, and bottle-feeding mothers are generally appropriately concerned with their babies. It is difficult to determine the extent of causality due to a number of confounding variables, such as the varied reasons families choose different feeding methods. Many believe that early bonding ideally increases response and sensitivity to the child's needs, bolstering the quality of the mother–baby relationship—however, many exceptions can be found of highly successful mother–baby bonds, even though early breastfeeding did not occur, such as with premature infants who may lack the necessary sucking strength to successfully breastfeed. Research following Bowlby's observations (above) created some concern about whether adoptive parents have missed some crucial period for the child's development. However, research on The Mental and Social Life of Babies suggested that the "parent-infant system," rather than a bond between biologically related individuals, is an evolved fit between innate behavior patterns of all human infants and equally evolved responses of human adults to those infant behaviors. Thus nature "ensures some initial flexibility with respect to the particular adults who take on the parental role.”[12] Paternal bonding Father playing with his young daughter—an activity that tends to strengthen the father–child bond. Main article: Paternal bond In contrast to the maternal bond, paternal bonds tend to vary over the span of a child's development in terms of both strength and stability. In fact, many children now grow up in fatherless households and do not experience a paternal bond at all. In general, paternal bonding is more dominant later in a child's life after language develops. Fathers may be more influential in play interactions as opposed to nurturance interactions. Father–child bonds also tend to develop with respect to topics such as political views or money, whereas mother–child bonds tend to develop in relation to topics such as religious views or general outlooks on life.[13] In 2003, a researcher from Northwestern University in Illinois found that progesterone, a hormone more usually associated with pregnancy and maternal bonding, may also control the way men react towards their children. Specifically, they found that a lack of progesterone reduced aggressive behavior in male mice and stimulated them to act in a fatherly way towards their offspring.[14] |
