Illinois, USA- New neuroscience research confirms the power of a handshake. Strangers who make a firm, friendly handshake make a better impression than those who do not. The greeting dates to ancient times when it was a way of showing one carried no weapons. The study was led by Beckman Institute researcher Florin Dolcos. The institute found that “a handshake preceding social interaction enhanced the positive impact of approach and diminished the negative impact of avoidance behavior on the evaluation of social interaction.” Furthermore, their results demonstrated increased sensitivity to approach than to avoidance behavior in the amygdala and superior temporal sulcus, which are linked to a positive evaluation of approach behavior. Additionally, the nucleus accumbens, a reward processing region, showed greater activity for handshake than for non-handshake conditions. Dolcos further highlighted in her findings that it is not just any handshake that leads to positive feelings. A firm, confident, yet friendly handshake, as is often promoted as good business practice, leads to the highest amount of positive feelings.
