Known for:The still-face paradigm and the mutual regulation model — decades of micro-analytic research showing that mismatch and repair, not continuous attunement, characterize healthy parent-infant interaction.
SEE THE PRACTICE
Turn a thought this research explains into one clear move.
THE THOUGHT
“I lost my temper — I'm a bad parent”
YOUR RECORDED RESPONSE
“A moment of anger is a moment, not a pattern. The pattern is what I do after.”
ONE PRIVATE MOVE
For three days, privately list one interaction each morning where you and your child were in sync—no conflict needed. Notice what you were actually doing during those moments.
Key findings
- 1978
The still-face experiment: infants confronted with a suddenly unresponsive mother become distressed and actively try to re-engage her, demonstrating that infants are participants in — and monitors of — the emotional exchange. The Infant's Response to Entrapment between Contradictory Messages in Face-to-Face Interaction ↗
- 1989
With Jeffrey Cohn, showed micro-analytically that normal mother-infant interaction moves constantly between coordinated and miscoordinated states, with matched states in the minority — and that dyads typically repair miscoordination within seconds.

- 1989
Formalized the mutual regulation model: emotional development is driven by the joint, two-way regulation of the interaction — including the reparation of interactive errors — rather than by flawless parental performance. Emotions and Emotional Communication in Infants (American Psychologist, 44) ↗
