"The strength of a child's attachment behaviour in a given circumstance does not indicate the 'strength' of the attachment bond. Some insecure children will routinely display very pronounced attachment behaviours, while many secure children find that there is no great need to engage in either intense or frequent shows of attachment behaviour".
Secure attachment A toddler who is securely attached to its parent (or other familiar caregiver) will explore freely while the caregiver is present, typically engages with strangers, is often visibly upset when the caregiver departs, and is generally happy to see the caregiver return. The extent of exploration and of distress are affected by the child's temperamental make-up and by situational factors as well as by attachment status, however. A child's attachment is largely influenced by their primary caregiver's sensitivity to their needs. Parents who consistently (or almost always) respond to their child's needs will create securely attached children. Such children are certain that their parents will be responsive to their needs and communications. In the traditional Ainsworth et al. (1978) coding of the Strange Situation, secure infants are denoted as "Group B" infants and they are further subclassified as B1, B2, B3, and B4.
Anxious-resistant insecure attachment Anxious-resistant insecure attachment is also called
ambivalent attachment. The C1 subtype is coded when:
"...resistant behavior is particularly conspicuous. The mixture of seeking and yet resisting contact and interaction has an unmistakably angry quality and indeed an angry tone may characterize behavior in the preseparation episodes..." Infants are depicted as anxious-avoidant insecure when there is: ''"...conspicuous avoidance of the mother in the reunion episodes which is likely to consist of ignoring her altogether, although there may be some pointed looking away, turning away, or moving away...If there is a greeting when the mother enters, it tends to be a mere look or a smile...Either the baby does not approach his mother upon reunion, or they approach in 'abortive' fashions with the baby going past the mother, or it tends to only occur after much coaxing...If picked up, the baby shows little or no contact-maintaining behavior; he tends not to cuddle in; he looks away and he may squirm to get down."'' Main proposed that avoidance has two functions for an infant whose caregiver is consistently unresponsive to their needs. Firstly, avoidant behaviour allows the infant to maintain a conditional proximity with the caregiver: close enough to maintain protection, but distant enough to avoid rebuff. Secondly, the cognitive processes organising avoidant behaviour could help direct attention away from the unfulfilled desire for closeness with the caregiver – avoiding a situation in which the child is overwhelmed with emotion ('disorganised distress'), and therefore unable to maintain control of themselves and achieve even conditional proximity.
Disorganized/disoriented attachment Ainsworth herself was the first to find difficulties in fitting all infant behaviour into the three classifications used in her Baltimore study. Ainsworth and colleagues sometimes observed 'tense movements such as hunching the shoulders, putting the hands behind the neck and tensely cocking the head, and so on. It was our clear impression that such tension movements signified stress, both because they tended to occur chiefly in the separation episodes and because they tended to be prodromal to crying. Indeed, our hypothesis is that they occur when a child is attempting to control crying, for they tend to vanish if and when crying breaks through'. Such observations also appeared in the doctoral theses of Ainsworth's students. Crittenden, for example, noted that one abused infant in her doctoral sample was classed as secure (B) by her undergraduate coders because her strange situation behaviour was "without either avoidance or ambivalence, she did show stress-related stereotypic headcocking throughout the strange situation. This pervasive behaviour, however, was the only clue to the extent of her stress". Drawing on records of behaviours discrepant with the A, B, and C classifications, a fourth classification was added by Ainsworth's colleague
Mary Main and Judith Solomon. In the Strange Situation, the attachment system is expected to be activated by the departure and return of the caregiver. If the behaviour of the infant does not appear to the observer to be coordinated in a smooth way across episodes to achieve either proximity or some relative proximity with the caregiver, then it is considered 'disorganised' as it indicates a disruption or flooding of the attachment system (e.g. by fear). Infant behaviours in the Strange Situation Protocol coded as disorganised/disoriented include overt displays of fear; contradictory behaviours or affects occurring simultaneously or sequentially; stereotypic, asymmetric, misdirected or jerky movements; or freezing and apparent dissociation. Lyons-Ruth has urged, however, that it should be wider 'recognized that 52% of disorganized infants continue to approach the caregiver, seek comfort, and cease their distress without clear ambivalent or avoidant behavior.' There is 'rapidly growing interest in disorganized attachment' from clinicians and policy-makers as well as researchers. Yet the Disorganized/disoriented attachment (D) classification has been criticised by some for being too encompassing. In 1990, Ainsworth put in print her blessing for the new 'D' classification, though she urged that the addition be regarded as 'open-ended, in the sense that subcategories may be distinguished', as she worried that the D classification might be too encompassing and might treat too many different forms of behaviour as if they were the same thing. Indeed, the D classification puts together infants who use a somewhat disrupted secure (B) strategy with those who seem hopeless and show little attachment behaviour; it also puts together infants who run to hide when they see their caregiver in the same classification as those who show an avoidant (A) strategy on the first reunion and then an ambivalent-resistant (C) strategy on the second reunion. Perhaps responding to such concerns, George and Solomon have divided among indices of Disorganized/disoriented attachment (D) in the Strange Situation, treating some of the behaviours as a 'strategy of desperation' and others as evidence that the attachment system has been flooded (e.g. by fear, or anger). Crittenden also argues that some behaviour classified as Disorganized/disoriented can be regarded as more 'emergency' versions of the avoidant and/or ambivalent/resistant strategies, and function to maintain the protective availability of the caregiver to some degree. Sroufe et al. have agreed that 'even disorganised attachment behaviour (simultaneous approach-avoidance; freezing, etc.) enables a degree of proximity in the face of a frightening or unfathomable parent'. However, 'the presumption that many indices of "disorganisation" are aspects of organised patterns does not preclude acceptance of the notion of disorganisation, especially in cases where the complexity and dangerousness of the threat are beyond children's capacity for response'. For example, 'Children placed in care, especially more than once, often have intrusions. In videos of the Strange Situation Procedure, they tend to occur when a rejected/neglected child approaches the stranger in an intrusion of desire for comfort, then loses muscular control and falls to the floor, overwhelmed by the intruding fear of the unknown, potentially dangerous, strange person'. Main and Hesse found that most of the mothers of these children had suffered major losses or other trauma shortly before or after the birth of the infant and had reacted by becoming severely depressed. In fact, 56% of mothers who had lost a parent by death before they completed high school subsequently had children with disorganized attachments. For example, Solomon and George found that unresolved loss in the mother tended to be associated with disorganised attachment in their infant primarily when they had also experienced an unresolved trauma in their life prior to the loss.
Significance of patterns Research based on data from longitudinal studies, such as the
National Institute of Child Health and Human Development Study of Early Child Care and the Minnesota Study of Risk and Adaption from Birth to Adulthood, and from cross-sectional studies, seeking to show associations between early attachment classifications and peer relationships typically fails to control for social background variables when seeking correlations between attachment classifications and other child behaviours, such as competence with peers. This is a general problem. Lyons-Ruth, for example, concluded that 'for each additional withdrawing behavior displayed by mothers in relation to their infant's attachment cues in the Strange Situation Procedure, the likelihood of clinical referral by service providers was increased by 50%.' Few if any rigorous studies which control for social background variables of the children it compares show even weak association between early experience and a comprehensive measure of social functioning in early adulthood but, if we ignore social background, early experience may seem to predict early childhood representations of relationships, which in turn may be held to correlate with later self and relationship representations and social behaviour. In like fashion, some studies have been claimed to show that infants with a high-risk for Autism Spectrum Disorders (ASD) may express attachment security differently from infants with a low-risk for ASD. On lie grounds, behavioural problems and social competence in insecure children may be said to increase or decline with deterioration or improvement in quality of parenting and the degree of risk in the family environment. ==Changes in attachment during childhood and adolescence==
