The Still Face Experiment: This procedure involves a caregiver interacting normally with an infant and then suddenly adopting a neutral, unresponsive expression. The infant's immediate distress and attempts to re-engage the caregiver demonstrate their innate drive for social reciprocity.
Observational Studies of Synchrony: Research has shown that the quality of attachment is directly correlated with the level of synchrony. Higher levels of coordinated behavior in the first months of life are predictive of more secure attachment styles later in childhood.
Controlled Observations: Studies often use high-speed filming and multiple observers to capture micro-interactions. This allows researchers to analyze subtle changes in expression that occur in fractions of a second, which might be missed by the naked eye.
| Feature | Reciprocity | Interactional Synchrony |
|---|---|---|
| Timing | Sequential (Turn-taking) | Simultaneous (Mirroring) |
| Action | Response to a signal | Coordinated, identical behavior |
| Analogy | A conversation | A synchronized dance |
| Focus | The 'flow' of interaction | The 'timing' and 'rhythm' |
Identify the Pattern: In exam scenarios, look for keywords. If the description mentions 'one after the other' or 'responding to a cry,' it is Reciprocity. If it mentions 'at the same time' or 'mirroring,' it is Interactional Synchrony.
Link to Attachment: Always explain why these interactions matter. They are not just behaviors; they are the building blocks of the Internal Working Model and secure attachment.
Evaluation Points: When discussing research, mention the difficulty of interpreting infant behavior. Because infants move constantly, it is hard to prove that a specific movement was a deliberate response rather than a random muscle twitch.
Imitation vs. Synchrony: Students often think synchrony is just imitation. While imitation is a part of it, synchrony is specifically about the coordination and timing of those shared behaviors.
Intentionality: It is a common mistake to assume infants have complex social intentions. While they are active partners, their responses are often reflexive or biologically driven rather than consciously planned social strategies.
Ecological Validity: Be careful with lab-based findings like the Still Face experiment. While they show what can happen, they may not perfectly represent the messy, distracted nature of real-world parenting.
