The power of expressions
In 1975, Edward Tronick presented a paper at the Society for Research in Child Development. The experiment he described was simple, but the results were dramatic. In fact, his findings still influence the way psychologists think about learning, particularly about how emotion and cognition are intertwined, and how relationships can best be maintained throughout our lives.
Tronick and his team at the Children’s Hospital Medical Centre in Boston invited mothers to interact normally with their baby – to smile, coo, play peek-aboo or whatever they enjoyed. They were then asked to assume a still face – a neutral expression showing no reaction at all – whatever the baby did.
The change in the previously happy infants was almost instantaneous. At first, they seem confused, often looking away and back again as if by doing so, things might improve. They would appear to “plead” for a reaction, trying out behaviours that had previously received a favourable response, such as smiling or clapping. When these failed, babies became visibly agitated. Some screamed or tried to grab their mother’s face. Still receiving no reaction, they would start to cry and/or appear to “give up”. All this in less than three minutes.
Since that trial, Tronick’s findings have been replicated and extended. Darwin Muir and colleagues at Queen’s University in Canada have shown this sequence of reactions to be so robust that it occurs when the mother isn’t actually present – that is, when the baby watches on a screen – and when the still face is assumed by caregivers or strangers.
Relationship psychologists, such as John Gottman at the University of Washington and Sue Johnson at the University of Ottawa, describe the same sequence of reactions to expressionlessness from a couple whose relationship is in difficulty.
These findings are important because they demonstrate how powerfully humans are “wired” to understand others and furthermore, that they learn best when they know the other person is genuinely trying to understand them.
This interaction – now referred to by psychologists as the “serve and return” – shows the interdependence of emotion and cognition. When we think no one is trying to understand us, we become stressed, unable to concentrate or learn. If this happens repeatedly, especially in very young children, it can lead to apathy, little enthusiasm to learn, a total loss of interest.
The best way to maintain positive relationships and foster optimal development in others is to spend time listening carefully and trying to understand. Perfect understanding is great when it happens – although Tronick estimates most only achieve it about 20 per cent of the time. However, a perfect response isn’t nearly as important as demonstrating your desire to understand and respond appropriately to others.
