Infant day care facilitates preschool social behavior

Seventy-one preschool-age children entering infant day care at varying times and receiving varying amounts of infant day care were compared on their reunion-with-parent behavior, teacher and parent ratings of their behavior, and playground play interactions. Age of entry into day care (≤ 6 months vs. > 6 months) had no significant effect on attachment to mother as measured by reunion behaviors or on play and socialization skills as measured by observation and behavior rating scales in a full-time day-care setting. Furthermore, children with more hours and months of day care engaged in less watching, solitary play, and teacher comfort-seeking behavior, and they showed more cooperative play, positive affect, peer interaction, and positive verbal interaction. Thus continuous infant day care in quality centers appears to facilitate preschool social behavior and does not negatively affect attachment behavior.     

Behavioral Inhibition, Heart Period, and Respiratory Sinus Arrhythmia: An Attachment Perspective

This study shows that relations between behavioral inhibition and cardiac activity may be clarified by identifying attachment status, whereas relations between security of attachment and cardiac activity may be clarified by identifying inhibition status. Assessments at 4.5 years (N = 126) included heart period (HP), respiratory sinus arrhythmia (RSA), behavioral inhibition (BI), and security of attachment. There was no main effect of BI status (Low, Medium, High) on either HP or RSA. Instead, it was only the Secure children who showed the predicted relation between low BI and high HP or RSA, with the Low BI-Secure group having significantly higher HP than either the High BI-Secure or the Low BI-Insecure groups. Turning to attachment, both HP and RSA increased significantly from an assessment during separation from mother to an assessment 3 min after reunion. The only subgroups showing a significant increase in HP, however, were those with both secure attachment and an absence of high BI.     

Attachment to Mother/Attachment to Father: A Meta-Analysis

An important tenet of attachment theory is that classification of security or insecurity as derived from the Strange Situation reflects the quality of an infant's relationship with its caregiver. One piece of evidence supporting this claim is the lack of concordance of classification between an infant and its mother and father. We performed a meta-analysis of the 11 studies that have examined the concordance of mother/father attachment to an infant. We found that security of attachment to one parent was dependent upon security to the other parent, that type of insecurity (avoidant/resistant) to one parent was dependent upon type of insecurity to the other, and that subcategory classification within the secure category (B1B2/B3B4) to one parent was dependent upon subcategory classification to the other. These data raise important questions regarding the meaning of infant attachment classification as derived from the Strange Situation. Among the possible explanations for the pattern of data are existence of concordant parenting styles and/or influence of infant temperament (possibly the tendency to cry upon separation) on classification of security/insecurity in the Strange Situation.     

The development of emotion expression during the first two years of life

This study examines the course of emotion expression development over the first 2 years of life in a sample of full-term and preterm children. 58 mother/infant pairs were videotaped at infant ages of 2 1/2, 5, 7 1/2, and 22 months, recording face-to-face interaction involving play and separation/reunion sessions. The tapes were coded on a second-to-second basis using Izard's facial affect coding system. Data analysis focused on (1) differences in expressive behavior at 22 months as a function of risk status, gender, attachment status, and patterns of earlier maternal contingency behavior; (2) stability of specific emotional expressive patterns across assessment periods; and (3) the relation of expressive behavior and security of attachment at 2 years to qualities of earlier affective interchange. Mother's contingency behavior (both general level and specific contingency patterns) appeared to have a material effect on the course of emotional development, as did birth status and gender. Prematurity was associated with differential socioemotional development well into the second year, much in contrast to the "catch-up effect" observed in linguistic and cognitive functioning. Discrete emotions analysis of attachment groups yielded differentiation along a broad negative/positive dimension, but it also showed that insecurely attached children can be characterized as showing inhibited anger expression. The results of this study are discussed within the framework of organizational models of infant affective development; attachment theory and discrete emotions approaches were found to yield different yet equally informative data on the course of socioemotional development.     

Mother-infant attachment: the importance of the mother's visual field.

The purpose of this study was to answer 2 questions: (1) how important to 2-year-old children is fact-to-face contact with the mother, and (2) do attachment behaviors, such as looking at, talking to, and being close to mothers, interact in a compensatory fashion? 24 male and female children, 18 to 30 months, were observed with their mothers for 15 minutes in 3 conditions: (1) mother facing tethered toys, (2) mother facing away from toys, and (3) mother behind a partition and not visible from toys. Observations were made by time-lapse photography techniques. Results indicated that the potential for face-to-face contact was important: children spent 94% of their time in mother's visual field when she faced the toys and 50% of their time in her visual field when she either faced away or was behind the partition. Overall, they established face-to-face contact about 12% of the time. Some compensation was observed: talking and physical proximity increased as visual contact decreased.     

Child emotionality and maternal responsiveness as predictors of reunion behaviors in the strange situation: links mediated and unmediated by separation distress

Children's emotionality--fear, anger, and joy--observed outside of the relationship with the mother (in standard laboratory paradigms), and within that relationship (in mother-child interactions), and mothers' responsiveness, all at 9 and 14 months, were examined as predictors of the reunion behaviors in the Strange Situation at 14 months in 112 children. Many predictors were linked to the reunion behaviors, but most of those relations were at least partially mediated by children's separation distress, which itself strongly predicted the reunion behaviors. Those relations were no longer significant when distress was controlled. Several links, however, remained significant, and they were unmediated by distress: Almost all involved measures assessed within the context of the mother-child relationship. In particular, possible markers of a suboptimal relationship (children's dampened joy and increased anger in interactions with the mother, poor maternal responsiveness) were associated with more avoidance and resistance upon reunion, even after accounting for the strong impact of distress. Studying how factors measured outside of and within early relationships influence the components of the attachment system may foster understanding of child behavior in the Strange Situation.     

Social attachment of the infant guinea pig to its parents in a two-choice situation

Twenty-four domestic guinea pigs (12 of each gender) served as subjects in this study, which investigated attachment by testing amount of time (maximum 5 min) the infants spent close to either the mother or the father in a two-choice situation during Weeks 2, 4, 6, and 8 after birth. Significantly more time was spent close to the mother during Weeks 2 and 4; reaction to the father appeared random. Time spent close to the mother declined across weeks, suggesting that maternal attachment weakens as the infant matures.     

Children's emotions and behaviors in response to infants' cries

Infant crying can elicit in others both a range of emotions and contrasting behavioral reactions, such as altruistic caregiving versus aggression. Variations in reactions to young infants' cries were examined in 60 children ranging in age from late preschool to preadolescence. Each child over-heard either a preterm or a full-term tape-recorded cry from an adjacent room. Then a mother, carrying her infant, came looking for her (previously) "crying" infant's bottle. Later each child was interviewed after hearing a tape recording of a preterm and a full-term cry. Children's emotions and behaviors thus were assessed in response to simulated, real distresses and hypothetical representations of distress. Children's self-reports of empathy, their verbalized intentions to help, their actual helping responses, and observers' ratings of negative emotion were common responses to cries at all ages. In addition there were significant increases with age in prosocial, behavioral interventions. Expressions of negative emotion were inversely related to subsequent forms of prosocial behavior that required direct interaction with the infant. The emotions and behaviors of most children were not influenced by whether they heard preterm or full-term cries. They were, however, able to discriminate between such cries and some articulated "theories" about the impact of the cries on the listener.     

A randomized controlled trial of a home-visiting intervention aimed at preventing relationship problems in depressed mothers and their infants

This study examined the effect of a mother–baby intervention on the quality of mother–child interaction, infant–mother attachment security, and infant socioemotional functioning in a group of depressed mothers with infants aged 1–12 months. A randomized controlled trial compared an experimental group ( n = 35) receiving the intervention (8–10 home visits) with a control group ( n = 36) receiving parenting support by telephone. There were assessments pre, post, and follow-up after 6 months. The intervention had positive effects on the quality of mother–infant interaction. Infants in the experimental group had higher scores for attachment security and for one aspect of socioemotional functioning, namely, competence. The intervention proved successful in preventing deterioration of the quality of mother–child interaction.     

The firstborn's adjustment to the birth of a sibling: a longitudinal assessment

41 middle-class families were interviewed at 1 month prepartum and 1, 4, 8, and 12 months after the birth of a second child to assess the reaction and adjustment of firstborn children to this event. Family members were also observed in a semistructured play session in order to obtain information concerning changes in familial interaction patterns. A log linear analysis was conducted to fit a hierarchical model to a 2 (child gender) X 2 (infant gender) X 4 (time of measurement relative to birth of infant) X 2 (presence or absence of problematic regressive behavior) X 14 (type of problematic behavior reported) matrix. A model with 2 statistically significant effects was found to fit the observed frequency matrix quite well, goodness-of-fit (GF) chi 2(312, N = 2,296) = 97.47, p less than .99. This model suggests (1) that the type of response displayed by the firstborns varied as a function of time since the birth; that their initial responses were either imitations of the infant or confrontations with the mother or infant, whereas responses at 4 months postpartum were characterized by numerous anxiety behaviors but fewer imitations or confrontations, and later responses were primarily confrontations with the increasingly intrusive and independent infant; and (2) that a greater frequency of problematic behavior was reported by the mothers of same-sex sibling dyads, especially at the 1- and 8-month postpartum assessments. Observational data indicated that mothers dramatically decreased their interactions with the firstborn children over time but that fathers tended to remain relatively stable in their frequencies of interaction.     

Does Infant Carrying Promote Attachment? An Experimental Study of the Effects of Increased Physical Contact on the Development of Attachment

This study was designed to test the hypothesis that increased physical contact, experimentally induced, would promote greater maternal responsiveness and more secure attachment between infant and mother. Low-SES mothers of newborn infants were randomly assigned to an experimental group (n = 23) that received soft baby carriers (more physical contact) or to a control group (n = 26) that received infants seats (less contact). Using a transitional probability analysis of a play session at 31/2 months, it was demonstrated that mothers in the experimental group were more contingently responsive than control mothers to their infants' vocalizations. When the infants were 13 months old, the Ainsworth Strange Situation was administered. Significantly more experimental than control infants were securely attached to their mothers. We infer from these results that for low-income, inner-city mothers, there may be a causal relation between increased physical contact, achieved through early carrying in a soft baby carrier, and subsequent security of attachment between infant and mother.     

Shedding further light on the effects of various types and quality of early child care on infant-mother attachment relationship: the Haifa Study of Early Child Care

The Haifa Study of Early Child Care recruited a large-scale sample (N = 758) that represented the full SES spectrum in Israel, to examine the unique contribution of various child-care-related correlates to infant attachment. After controlling for other potential contributing variables--including mother characteristics, mother-child interaction, mother-father relationship, infant characteristics and development, and the environment--this study found that center-care, in and of itself, adversely increased the likelihood of infants developing insecure attachment to their mothers as compared with infants who were either in maternal care, individual nonparental care with a relative, individual nonparental care with a paid caregiver, or family day-care. The results suggest that it is the poor quality of center-care and the high infant-caregiver ratio that accounted for this increased level of attachment insecurity among center-care infants.     

Young Children's Trust in Their Mother's Claims: Longitudinal Links With Attachment Security in Infancy

In a longitudinal study of attachment, children ( N = 147) aged 50 and 61 months heard their mother and a stranger make conflicting claims. In 2 tasks, the available perceptual cues were equally consistent with either person's claim but children generally accepted the mother's claims over those of the stranger. In a 3rd task, the perceptual cues favored the stranger's claims, and children generally accepted her claims over those of the mother. However, children's pattern of responding varied by attachment status. The strategy of relying on the mother or the stranger, depending on the available perceptual cues, was especially evident among secure children. Insecure-avoidant children displayed less reliance on their mother's claims, irrespective of the available cues, whereas insecure-resistant children displayed more.     

Children's strategies for coping with adverse home environments: an interpretation using attachment theory.

The coping strategies of four groups of maltreated children were compared with those of adequately reared children. The children were videotaped in a brief play session with their mothers, then in the Strange Situation, and finally during free play while the parent(s) were being interviewed. The coded videotapes of mother-child interaction yielded four scores for the children: cooperation, compulsive compliance, difficultness, and passivity. The coded videotapes of the Strange Situation yielded ten patterns of child attachment to the mother. The coded observations of play during the interview were analyzed in terms of seven child behaviors. The results indicated that abused, and abused-and-neglected children were difficult or compliant in interaction with their mothers, avoidant under stress, and aggressive with siblings; neglected children were cooperative in play with the mother, anxious under stress, and aggressive with siblings; adequately reared children were cooperative with both their mothers and siblings and secure under stress. Older children who had experienced abuse were less difficult and more compulsively compliant. Both marginally maltreated and adequately reared 1-year-olds were more difficult than either older or younger children from those groups but at all ages cooperation was the dominant pattern. The coherencies in the children's coping strategies were interpreted in terms of underlying internal representational models of relationships.     

Adolescent adjustment, social systems and parental separation

The changing positions of different members of adolescent support networks are examined with respect to adolescent age (11–15) and sex, and, in particular, with respect to changes following parental separation. Older children’s reports of less parental support are consistent with expectations of diminishing attachment. However, the relative importance of same sex friends for provision of support for girls, in comparison to boys, suggests more flexibility in the sense of their being less tied to parents for support. The comparison between children from different family types revealed no differences in respect of relations with same sex or opposite sex friends. Hence, no compensation or spill over from parental separation was evident. However, there was a clear system effect in that children from divorcing families that lived with their mother provided relatively more support for mother, and also reported less acceptance from their fathers in comparison to those children where no parental separation had taken place. Their adjustment will depend, at least in part, on the functioning of their broader social networks.     

Infant – Mother Attachment among the Dogon of Mali

This study of mothers and infants from the Dogon ethnic group of Mali, West Africa examined three attachment hypotheses: (1) that infant attachment security is linked to the quality of mother-infant communication, (2) that mothers of secure infants respond more sensitively to their infants than do mothers of insecure infants, and (3) that infant disorganization is linked to maternal frightened or frightening behaviors. Participants were 27 mother-infant pairs from a rural town and 15 mother-infant pairs from two agrarian villages; infants ranged in age from 10 to 12.5 months at the first assessment. The distribution of the Strange Situation classifications was 67% secure, 0% avoidant, 8% resistant, and 25% disorganized. Infant attachment security was significantly related to the quality of mother-infant communication as observed in a well-infant exam. The correlation between infant attachment security ratings and maternal sensitivity (assessed in the home) was modest and approached significance. Mothers of disorganized infants had significantly higher ratings of frightened or frightening behaviors. Maternal sensitivity predicted little of the variance in infant security; however, the addition of the frightened/frightening variable in the regression equation tripled the explained variance. The findings are discussed in light of Dogon childrearing practices and key tenets of attachment theory.     

Child abuse by siblings

The case histories of five children who inflicted serious injuries on their younger siblings are described in detail. The children shared several experiences in common: They had been physically abused themselves; their families were undergoing crises, which accentuated their maternal deprivation and rejection; they were burdened with excessive caretaking for the target sibling, who was perceived as the favorite; they had also experienced the recent loss of their father or paternal caretaker. The psychodynamics associated with sibling abuse represented an intensification of “normal” sibling rivalry due to the abuser's own maltreatment and deprivation. Pent-up rage towards the mother was displaced onto the sibling rival. The abusers made use of identification with the aggressor as a prominent mechanism of defense. The sibling attacks were adaptive for the abusers in the following ways: (a) They afforded them a measure of revenge against the more highly regarded sibling rival; (b) they served as an outlet for rage directed towards the mother; (c) they were used as an attention getting device; (d) they provided a sense of mastery over the trauma of their own abuse; and (e) were used to “educate” the abusing parent.     

Infant approach behavior as related to attachment.

The chief purpose of this study was to identify characteristics that distinguish approach as an attachment behavior from approach serving other behavioral systems. Locomotor approaches of 16 male and 10 female white middle-class infants to an attachment figure (the mother) and to a nonattachment figure (the visitor-observer) were examined under naturalistic conditions at home. Observations were made during 4-hour home visits at 3-week intervals; those from 26 to 54 weeks were used. When approach was examined in a free-choice situation and without regard to behavioral context, infants approached the mother proportionally (though slightly) more often than the visitor (p less than .05). In 2 behavioral contexts, however, spontaneous infant approaches were sharply differential to the mother; approaches accompanied by crying and approaches terminating in a pickup appeal were directed almost exclusively to the mother (p less than .0001 for both). Touching upon completion of the approach was not differential, except in the context of a pickup appeal. Object-oriented approaches were more often directed to the visitor than to the mother (p less than .002) and may be either exploratory or affiliative. It is suggested that neither approach nor touching can be assumed to serve the attachment system without consideration of context- both environmental and behavioral.     

Early Predictors of Attachment in Infants with Cleft Lip and/or Palate

Previous studies have found that children with cleft lip and palate (CLP) and isolated cleft palate (CP) have elevated risk for a variety of psychosocial problems, but the origins of such problems are unclear, We excted that early medical and other stressors during infancy—including feeding problems and facial disfigurement—would have adverse effects on the infant, his or her caregivers, and the family environment, leading to a higher than expected rate of insecure attachments among infants with clefts. Twelve-month attachment classifications of CLP, CP, and comparision group infants were examined. No significant group differences in attachment status were found. When 3-month infant, maternal, and social/family characteristics were examined as potential predictors of insecure attachment, predictors interacted with diagnostic status. For the cleft group, infant and maternal characteristics, but not family characteristics, significantly predicted insecure attachment. For the comparison group, maternal and family characteristics, but not factors associated with the infant, were predictive. Infants with clefts despite their special needs and caregiving requirements, seem not to have elevated risk for insecure attachments at the end of their first year. Contrary to social-psychological formulations, the facial appearance of infants with CLP had no adverse effect on the quality of their maternal attachment.     

Initiating day care at three years of age: effects on attachment

Using the Ainsworth-Wittig strange situation, 12 42-month-old children with approximately 6-months of day-care experience were compared with individually matched children who had not had group child-rearing experience; 8 members of each experience group were female, and 4 members were male. While the day-care children showed less distress than the home-care children in the latter parts of the laboratory situation, the 2 groups were not different with respect to most other behaviors, including those toward the mother. However, day-care experience appeared to have differential effects as a function of sex; large differences were often found between the scores of the male subgroups, whereas the differences between the female subgroups were usually small. The day-care males exhibited the most exploratory manipulation, and the home-care males showed the most approach and proximity seeking toward the mother and the strongest approach toward and avoidance of the stranger. These results did not support the idea that day-care experience impair attachment to the mother.
