Mirroring is the largely unconscious copying of another person's gestures, expressions, posture or speech during interaction — and, in a separate therapeutic sense, the attuned reflecting-back that helps a person build a stable sense of self.
Heinz Kohut named mirroring as a developmental need in self psychology; Tanya Chartrand and John Bargh named the behavioural version the 'chameleon effect' in 1999.
// Where it sits
Most of it happens well below the level where you could decide to stop.
What it really means
In 1999, Tanya Chartrand and John Bargh sat participants down with a partner who had been instructed to shake a foot, or rub their own face, at intervals. The participants started doing it too. Afterwards, they hadn't noticed the partner doing it, and hadn't noticed themselves doing it either. Chartrand and Bargh called this the chameleon effect, and its most interesting feature is that awareness plays no part in it at all.
What mirroring buys is liking — being copied makes people warmer toward the copier, and in later work more helpful and more generous too. Which is presumably why it exists: an automatic social glue that costs nothing to run.
But there's a condition on it that is rarely mentioned in the popularised version, and it's the sharpest thing in the literature. When the person mimicking belongs to an outgroup, being mimicked can reduce liking. The behaviour hasn't changed — the reading of it has. From one person it registers as rapport; from another, as mimicry in the older sense of the word. Which is the condition the popularised version leaves out. Deliberate copying is not itself the problem — in these experiments the confederate copies on instruction, subtly enough to go unnoticed, and is liked more for it. What flips the result is who is doing the copying.
Where it comes from
Same root as 'admire' — which happens to suit both senses of the word rather well.
Myths & misconceptions
Mirroring is a conscious persuasion technique you perform.
In the research it happens outside awareness entirely — participants noticed neither the behaviour they copied nor the fact that they were copying it.
Mimicking someone always makes them like you more.
It's conditional. When the mimicker is an outgroup member, being mimicked can reduce liking rather than increase it — the same behaviour reads as rapport or as mockery depending on who's doing it.
Compare & contrast
Mirroring vs empathy
Mirroring is an automatic motor and expressive echo; empathy is understanding what another person is experiencing. Mirroring can support empathy and often accompanies it, but it runs without it — you can copy someone's posture perfectly while understanding nothing about them.

|---|---|---|
| Is | Behavioural echo | Understanding |
| Conscious? | Rarely | Often |
| Requires the other | Present | Not necessarily |
| Can be faked | Yes, badly | Harder |

Tell it apart
Questions people ask
- Are mirror neurons the explanation?
- Not settled, and worth resisting the confident version. Researchers argue mimicry can be embodied and adaptive without requiring higher-order mental representation, and mirror-neuron accounts of social behaviour remain contested.
- What is mirroring in therapy?
- A different sense of the word. In Kohut's self psychology it's the attuned response to a person's need to be recognised — something they gradually internalise as self-esteem, rather than a behaviour the therapist copies.
- Does mimicry change more than liking?
- Yes. Mimicked participants have been found more helpful and more generous in donation tasks — so the effect reaches behaviour, not just rapport.
