Attachment on the NCE: Bowlby, Ainsworth, and the four patterns.
The Strange Situation, the attachment styles and how they show up in adult items.

Attachment is one of the most reliably tested topics in the human growth and development area, and it comes down to two names, one procedure and four patterns.
Two names
John Bowlby proposed that infants are biologically predisposed to form an attachment to a caregiver, that this bond serves survival, and that early attachment builds an internal working model of relationships. Mary Ainsworth tested the idea with the Strange Situation, a laboratory procedure in which a caregiver leaves and returns while an observer watches the child's reaction. Harry Harlow's monkey studies, showing that infants prefer comfort to food, are the usual supporting citation.
Four patterns
- Secure: distressed at separation, comforted at reunion, uses the caregiver as a base for exploration. The majority pattern.
- Anxious-ambivalent (resistant): very distressed at separation, not easily comforted at reunion, clingy and angry at once.
- Avoidant: little visible distress at separation, ignores or avoids the caregiver at reunion.
- Disorganized (added later by Main and Solomon): contradictory, confused behavior; associated with frightening or inconsistent caregiving and with maltreatment.
Internal working models and what they predict
Bowlby's central claim was not about infancy for its own sake. The attachment relationship builds an internal working model: a set of expectations about whether others will be available and whether the self is worth caring for. A securely attached child expects help and approaches; an avoidant child expects rejection and suppresses the bid; an ambivalent child expects inconsistency and escalates it. The exam tests this as the mechanism by which early experience reaches adult relationships, and as the reason a counselor's reliability matters so much to clients with insecure histories.
Bowlby also described the response to separation in three phases: protest, despair and detachment. A hospitalized toddler cries and searches, then grows quiet and withdrawn, then appears to recover while actually disengaging. An item that describes a child who seems "fine" after a long separation and ignores the parent on return is describing detachment, not resilience. Harlow's rhesus monkeys, who clung to the cloth mother and visited the wire one only to feed, are the supporting evidence that attachment is about comfort, not nourishment.
How items frame it
An item describes a toddler's behavior at reunion and asks for the pattern, or describes a caregiving style and asks for the likely outcome. Sensitive, responsive caregiving predicts security. Inconsistent caregiving predicts ambivalence. Rejecting caregiving predicts avoidance. In adult items, the styles reappear as secure, preoccupied, dismissing and fearful, from Bartholomew's model, and the exam may ask how attachment history affects the therapeutic relationship.
Adult attachment and the counseling room
Two adult lines appear on the exam. Hazan and Shaver, in 1987, argued that romantic love is an attachment process and that adult partners show the same secure, avoidant and anxious patterns as infants. Bartholomew and Horowitz, in 1991, crossed a positive or negative model of self with a positive or negative model of others, producing four styles: secure, preoccupied, dismissing and fearful. Mary Main's Adult Attachment Interview classifies adults by how coherently they narrate their childhood rather than by what happened in it, and finds that a parent's classification predicts the infant's.
In practice items, attachment shows up as the therapeutic relationship. A client with a dismissing style minimizes problems, cancels when things get close and treats the counselor's care as unnecessary; the counselor's task is steady availability without pursuit. A preoccupied client seeks reassurance, reads cancellations as abandonment and may escalate between sessions; the task is consistent boundaries that are themselves the corrective experience. The keyed answer usually names the counselor as a secure base: predictable, attuned and not reactive to the client's test of the relationship.
Three items to practice on
A toddler plays comfortably while the mother is present, cries when she leaves, and is quickly soothed and returns to play when she comes back. Secure. A toddler barely reacts when the mother leaves and turns away when she returns, though heart-rate data in the original studies show the child is distressed. Avoidant. A toddler clings before separation, is inconsolable during it, and on reunion reaches for the mother while arching away and hitting. Ambivalent, also called resistant. A toddler freezes, approaches the mother with head averted, or collapses to the floor on reunion. Disorganized, added by Main and Solomon and associated with frightening or frightened caregiving.
Distribution matters for one item type: in Ainsworth's middle-class American samples, roughly two thirds of infants were secure, about a fifth avoidant and the remainder ambivalent. Cross-cultural work found more avoidance in some Western European samples and more ambivalence in some Japanese and Israeli kibbutz samples, which the exam uses to test whether you know that attachment patterns reflect caregiving norms, not deficits in the children.
Neighbors
Do not confuse attachment with bonding (the caregiver's tie to the infant), with imprinting (Lorenz, in animals), or with Erikson's trust versus mistrust stage, which is the psychosocial framing of the same period. Items sometimes offer all three as distractors.
