Attachment and Temperament

Attachment is one of the most reliably tested topics in developmental psychology, precisely because the board loves to trade on confusable names, patterns, and studies: Bowlby versus Ainsworth, avoidant versus resistant, imprinting versus attachment. A single careless swap of a label costs an item. This lesson sorts the theory from the studies and gives you a clean way to tell temperament (a child's built-in style) apart from attachment (a relationship quality), so both survive a fast-paced exam.

Bowlby's attachment theory

John Bowlby, a British psychiatrist working from an ethological and evolutionary perspective, argued that infants are biologically predisposed to form a strong emotional bond, or attachment, with a primary caregiver because proximity to a protector improved survival across human evolutionary history. Bowlby described this development in four phases.

• Pre-attachment (birth to about 6 weeks): the infant produces innate signals such as crying, smiling, and grasping that draw caregivers close, but does not yet discriminate one adult from another.
• Attachment-in-the-making (6 weeks to about 6-8 months): the infant begins to recognize and prefer familiar caregivers, responding more readily to them, though protest at separation is still mild.
• Clear-cut attachment (about 6-8 months to 18-24 months): a genuine bond to a specific figure, often called monotropy for the primacy of one central attachment figure, is evident. This is when separation anxiety and stranger anxiety emerge, and the caregiver becomes what Bowlby termed a secure base, a safe platform from which the infant explores the world, and a safe haven, a source of comfort to return to when frightened.
• Goal-corrected partnership (from about 2 years onward): the child begins to understand the caregiver's feelings, goals, and plans, and can negotiate separations rather than simply protesting them.

Out of repeated caregiving experiences the child builds an internal working model (IWM), a mental representation of the self as worthy or unworthy of love and of others as reliable or unreliable, which the child then carries forward as a template for later relationships, including romantic ones in adulthood. Bowlby treated the early years as a sensitive period for forming this first bond, a window when attachment forms most readily, though he was careful to describe it as sensitive rather than strictly critical, since human bonds can still form, with more difficulty, afterward. Philippine early-childhood policy quietly assumes this same timeline: RA 11148, the First 1000 Days Law, funds maternal and infant nutrition and caregiving support precisely across the pre-attachment through clear-cut attachment phases, when the relational foundation Bowlby described is being laid.

Ainsworth's Strange Situation and the four patterns

Mary Ainsworth, Bowlby's student and collaborator, operationalized attachment quality with the Strange Situation, a structured laboratory procedure of about eight episodes in which an infant experiences a novel room, the arrival of a stranger, two brief separations from the caregiver, and two reunions. What matters most for scoring is not the separation distress itself but how the infant behaves at reunion. From this procedure Ainsworth identified three original patterns, and researchers Main and Solomon later added a fourth.

Pattern	Reunion behavior	Caregiver style	Resulting IWM
Secure (Type B)	Distressed by separation, easily comforted and quickly returns to play at reunion	Consistently sensitive and responsive	Self as worthy of love, others as reliable
Avoidant (Type A)	Shows little distress, actively ignores or avoids the caregiver at reunion	Consistently unresponsive or rejecting	Self-reliant defense against expected rejection
Resistant / ambivalent (Type C)	Very distressed by separation, but resists comfort at reunion, clingy yet angry	Inconsistent, unpredictably responsive	Anxious uncertainty about caregiver availability
Disorganized (Type D)	Contradictory, dazed, or fearful behavior at reunion, no coherent strategy	Frightened or frightening, often linked to maltreatment	Fear without a coping strategy

Sensitive responsiveness, the caregiver's ability to read and promptly meet the infant's signals, is the strongest predictor of a secure classification. Cross-cultural replications by Van IJzendoorn and Kroonenberg found secure attachment is the most common pattern in every culture studied, but the balance of insecure types shifts: German samples showed more avoidant classifications, consistent with a cultural emphasis on early independence, while Japanese and Israeli kibbutz samples showed more resistant classifications, consistent with infants rarely being left with strangers.

Harlow's monkeys: contact comfort over feeding

Before Ainsworth's method existed, Harry Harlow challenged the dominant behaviorist explanation of attachment, sometimes nicknamed cupboard love or drive-reduction theory, which held that infants attach to whoever feeds them. Harlow raised infant rhesus monkeys with two surrogate mothers: a bare wire mother fitted with a feeding bottle, and a soft cloth mother with no food. Contrary to drive-reduction predictions, the infant monkeys spent most of their time clinging to the cloth mother and ran to her for comfort when frightened, visiting the wire mother only to feed. Harlow concluded that contact comfort, the pleasurable, reassuring sensation of touching something soft and warm, is a more powerful basis for attachment than nourishment. Monkeys raised in total isolation from any mother figure later showed severe social and emotional deficits that were difficult to reverse, evidence Harlow used to argue for an early sensitive period in primates as well as humans.

Imprinting: Lorenz and the ethological root

Konrad Lorenz, an ethologist, studied imprinting in precocial birds such as greylag geese: newly hatched goslings will follow and form a lasting attachment to the first moving object they see during a brief critical period after hatching, whether that object is the mother goose or Lorenz himself. Imprinting occurs rapidly, requires no reinforcement or feeding, and is largely irreversible once the critical period closes, which is why the phenomenon supported Bowlby's broader ethological argument that attachment in animals, and by extension in humans, is a built-in, evolutionarily prepared process rather than something learned purely through association with food. The board-tested distinction is that imprinting applies to precocial species with a rigid, short critical period, while human attachment unfolds more gradually across a longer, more flexible sensitive period, since human infants are altricial and dependent for years, not hours.

Temperament: Thomas and Chess and goodness of fit

Where attachment describes the quality of a relationship, temperament describes something different: a biologically based, largely inborn style of behavioral and emotional reactivity, present from early infancy, that answers how a child behaves rather than what or why. Alexander Thomas and Stella Chess, through the landmark New York Longitudinal Study (NYLS), rated infants on nine behavioral dimensions, including activity level, adaptability, and intensity of reaction, and found the ratings clustered into three broad temperament types.

Type	Approx. share of sample	Core pattern
Easy	About 40 percent	Regular routines, positive mood, adapts readily to new situations
Difficult	About 10 percent	Irregular routines, intense and often negative reactions, slow to adapt
Slow-to-warm-up	About 15 percent	Low activity, initially withdraws from novelty but adapts gradually with repeated exposure

The remaining infants showed mixed profiles that did not cleanly fit one type. Thomas and Chess's most exam-relevant contribution, however, is goodness of fit: the degree of match between a child's temperament and the demands, expectations, and parenting style of the caregiving environment. A difficult temperament does not by itself predict poor outcomes; what predicts adjustment is whether caregivers adapt their handling to the child's style. Because standardized temperament inventories are formal psychological assessment tools, administering and interpreting them in the Philippines falls under the practice reserved for licensed psychologists and psychometricians by RA 10029, the Philippine Psychology Act of 2009.

Board traps and takeaways

• Do not confuse Bowlby (the theorist who described the phases, internal working models, and the secure base) with Ainsworth (who built the Strange Situation and named the four patterns).
• Avoidant versus resistant is the pair examinees mix up most: avoidant infants show minimal distress and ignore the caregiver at reunion, while resistant infants are highly distressed yet resist being soothed.
• Disorganized attachment (Type D) was added later by Main and Solomon, not part of Ainsworth's original three-pattern scheme, and is strongly associated with frightening or maltreating caregiving.
• Harlow refuted cupboard love: monkeys chose comfort over food, proving attachment is not simply a byproduct of feeding.
• Imprinting is not attachment: imprinting is Lorenz's rapid, largely irreversible bond in precocial animals during a fixed critical period, while human attachment develops more gradually over a longer sensitive period.
• Temperament is not attachment security: temperament is the inborn behavioral style measured by Thomas and Chess, and its impact on adjustment depends on goodness of fit with the caregiving environment, not on the type alone.
