Questions: Stranger Anxiety and Separation Distress

Question 1

A parent is concerned because their 9-month-old suddenly cries whenever a friendly grandparent approaches, even though the baby was perfectly calm around grandparents at 3 months. Which interpretation best fits the developmental evidence?

• A. The baby has developed a negative association with the grandparent through some unpleasant experience
• B. This is a normal developmental milestone — stranger anxiety signals that the infant has formed clear mental representations of familiar caregivers and can now distinguish familiar from unfamiliar
• C. The baby is showing early signs of anxious attachment and should be evaluated by a clinician
• D. The infant missed a critical period for early socialization and is now overly sensitive to strangers

Answer: (B)

Stranger anxiety emerges around 6–8 months precisely because it requires cognitive prerequisites: the infant must have consolidated stable representations of familiar caregivers before 'stranger' becomes a meaningful category. The fact that the baby was fine at 3 months (before these representations solidified) and now reacts is the expected developmental trajectory, not a sign of pathology. The onset of stranger anxiety is evidence that the attachment system is working correctly.

Question 2

A 14-month-old shows intense separation distress when her mother leaves but calms quickly after reunion. A different 14-month-old shows almost no distress when his mother leaves and seems equally comfortable with a stranger. What is the best developmental interpretation?

• A. The second infant is showing healthier development — independence at this age is a sign of secure attachment
• B. The first infant's pattern is consistent with secure attachment; the second infant's lack of distress and indifference to the stranger may warrant monitoring as a possible sign of disrupted attachment
• C. Both patterns are developmentally equivalent — all individual differences in the first two years fall within normal range
• D. The first infant has anxious attachment; the second has secure attachment because securely attached infants do not show separation distress

Answer: (B)

The absence of separation distress in a 14-month-old — the age when it should be near its peak — is not a sign of independence; it may signal that the attachment bond is disrupted or insecure. Securely attached infants typically show distress at separation and comfort-seeking at reunion (they use the caregiver as a safe base). The first infant's pattern — distress then quick recovery — is the hallmark of secure attachment. Mistaking emotional blunting for emotional maturity is a common error when applying this topic.

Question 3

Separation distress emerges at 6–8 months because that is when infants first form an attachment bond with their caregivers.

• T. True
• F. False

Answer: False

Attachment begins forming earlier than 6–8 months. The emergence of separation distress at this age reflects a cognitive development, not the first formation of attachment. Before 6–8 months, infants lack stable mental representations of caregivers as specific, persistent individuals — and they also lack the developing object permanence that lets them understand that an absent person still exists and can return. It is these cognitive advances that make the caregiver's absence distressing. Attachment predates the distress; cognitive development enables the distress.

Question 4

An infant can show intense stranger anxiety and still have a secure attachment — temperamental behavioral inhibition can amplify fear responses independently of attachment quality.

• T. True
• F. False

Answer: True

Stranger anxiety intensity reflects two sources: attachment security and temperamental behavioral inhibition (a trait-like tendency to respond strongly to novelty). A securely attached but temperamentally inhibited infant may cry vigorously at strangers while still having a completely healthy attachment relationship — they will use the caregiver as a safe base and recover well after separations. Confusing temperamental intensity with attachment insecurity leads to misinterpreting normal variation as pathology.

Question 5

Why does separation distress naturally decrease through the second and third years of life, even without specific intervention or gradual desensitization?

Model answer: As object permanence and object constancy develop, the child gains the cognitive capacity to maintain a stable mental representation of the caregiver even when that person is not physically present. The infant can now 'hold the caregiver in mind' — understanding that the absent person still exists, remembers them, and will return. This representational capacity removes the cognitive basis for distress: the caregiver's absence no longer means the caregiver has ceased to exist or is gone forever.

The attenuation of separation distress is a cognitive milestone, not just habituation to repeated separations. The key development is object constancy — the ability to maintain a stable, positive mental image of a loved person across absence. Children with secure attachment develop this capacity more readily, which is one reason secure attachment in infancy predicts better emotional regulation in toddlerhood and beyond.
