A neuroscientist and medical doctor, Dr Tara Swart, has shared a technique on the Diary of a CEO podcast that suggests focusing on someone's left eye during conversation can create stronger emotional bonds. Dr Swart, author of books including The Science of the Brain, explained that this 'left eye trick' is rooted in early mother-infant bonding.
According to Dr Swart, most people are right-handed and naturally hold their baby in their left arm, freeing their dominant hand for tasks. This means that when a parent gazes at their child, their right eye aligns with the baby's left eye. This specific visual connection stimulates the amygdala, the brain's emotional centre, creating an 'emotional resonance loop' that is integral to bonding.
Dr Swart stated that 'right eye to left eye contact is the most bonding eye contact you can have with someone' and that it is 'the statistically most likely one to create good resonance between you.' She recommended using this technique in situations where building rapport is crucial, such as on a first date.
Beyond eye contact, Dr Swart emphasised the importance of body language in building trust. She noted that physical gestures like handshakes, hugs, and kisses on the cheek can help lower a person's psychological guard. She recalled that before her interview with Steven Bartlett, sharing a hug and a few jokes helped initiate a bond.
In an Instagram post, Dr Swart said: 'Why right-to-left eye contact creates stronger bonds. The way we make eye contact can actually deepen our connections. Specifically right to left eye contact can play a key role in building stronger emotional bonds with others. While more research is needed, some of the potential mechanisms behind this could be.'
