Questions: Parent-Infant Synchrony and Responsive Caregiving

Question 1

In the Still Face Paradigm, after the caregiver's face goes neutral and unresponsive, the infant escalates vocalizations, pointing, and bids for eye contact. What does this behavior most directly demonstrate about the infant's role in synchrony?

• A. The infant is imitating social behaviors they have observed in other children
• B. The infant actively solicits contingent social responses and is distressed when they fail to arrive
• C. The infant has already formed secure attachment and is attempting to comfort the caregiver
• D. The infant's vocalizations are random motor activity unrelated to the caregiver's state

Answer: (B)

The escalation of bids for engagement is the central evidence that infants are not passive recipients — they actively expect and seek contingent responses. When the expected response fails to arrive, they intensify their efforts to reinstate it. This demonstrates that the infant is an active, initiating partner in the exchange, not merely a target of caregiving. Options A and C misread the developmental sequence; option D is directly falsified by the contingency between the infant's bids and the caregiver's state change.

Question 2

A caregiver consistently brings toys into the infant's visual field whenever the infant looks away, re-engaging the infant even when the infant is clearly signaling a need for a break. How does synchrony theory characterize this caregiving pattern?

• A. Sensitive caregiving — following the infant's interest promotes cognitive development
• B. Under-responsive caregiving — the infant will develop anxious attachment from insufficient engagement
• C. Intrusive caregiving — the caregiver overrides the infant's own regulatory signals, disrupting self-regulation development
• D. A neutral pattern that only becomes problematic if accompanied by negative affect

Answer: (C)

Overriding the infant's gaze-away signals is intrusive or over-stimulating caregiving — the second distinct failure mode of synchrony. When the caregiver ignores bids for distance, the infant's emerging capacity to regulate their own arousal is disrupted, because their regulatory signals don't produce the expected effect. This is not sensitive caregiving (A) and is not under-responsive (B) — under-responsiveness is the opposite failure, where the caregiver fails to respond to the infant's bids for *engagement*. Option D understates the disruption: ignoring regulatory signals is problematic in itself.

Question 3

Both under-responsive caregiving and intrusive (over-stimulating) caregiving can produce insecure attachment, even though they represent opposite failures of synchrony.

• T. True
• F. False

Answer: True

Under-responsiveness deprives the infant of contingent feedback needed to build expectations that others will respond — producing uncertainty about caregiver availability. Intrusiveness ignores the infant's 'I need a break' signals — producing uncertainty about whether the infant's own regulatory cues matter. These are opposite failure modes, but both disrupt the mutually regulated, contingent exchange that builds security. The mechanism of insecurity differs even when the outcome (insecure attachment) is similar.

Question 4

In parent-infant synchrony, the caregiver leads the interaction while the infant responds; the quality of synchrony is therefore primarily a measure of parental sensitivity.

• T. True
• F. False

Answer: False

Synchrony is genuinely bidirectional. Infants actively initiate interactions, signal overstimulation by looking away, and escalate bids when responses fail — they regulate the interaction, not just respond to it. The caregiver responds to the infant just as the infant responds to the caregiver. Framing synchrony as caregiver-led misses the core mechanism: it is the *mutual*, contingent responsiveness of both partners that constitutes synchrony. Parental sensitivity matters, but synchrony measures the quality of the dyadic exchange, not only the caregiver's behavior.

Question 5

How is parent-infant synchrony the mechanism through which attachment security is built, and why does improving parental sensitivity in video feedback interventions produce measurable improvements in attachment outcomes?

Model answer: Attachment security (the outcome) is constructed through accumulated experiences of contingent responsiveness (the mechanism). When a caregiver reliably responds to the infant's signals with appropriate timing — matching affect, responding to bids, following the infant's regulatory pace — the infant develops an expectation that others are available and responsive. This expectation is the internal working model that shapes later relationships. Video feedback interventions improve outcomes because they make caregivers aware of micro-level timing and responsiveness — specifically, when they are missing the infant's cues or overriding their regulatory signals — allowing them to adjust moment-to-moment behavior. Better synchrony quality directly improves the experiences that generate a secure internal working model.

The connection is causal: synchrony is not a byproduct of a good relationship but the process through which the relationship quality is created. This is why the intervention point is the quality of the moment-to-moment exchange, and why improvements in synchrony translate directly into improvements in the attachment outcome measure.
