Why people Tilt Right First While Kissing

London: Do you know why people tilt their head to the right rather than to the left when kissing or hugging? There is some science to it. According to the researchers, when touching others in a social context, for example kissing or hugging, people often have a lateral preference. “In general, the population at large has a preference of tilting the head to the right when kissing, to initiate a hug with the right hand, and to cradle a baby in the left arm,” elaborated Packheiser. “With regard to kissing and hugging, the assumption is that people have a dominant hand which they use to initiate the motion. According to the theory, the dominant hand is kept unoccupied when cradling a child so that it can be used to perform other tasks,” Packheiser noted.

The researchers explained that the left shift in emotional — as opposed to neutral — situations by speculating that emotions are primarily processed in the right brain hemisphere, which is responsible for movements of the left side of the body. The theory of right-hemispheric processing of emotions is backed by behavioural data from studies on social touch as well as by results gained in imaging and neurophysiological studies. “As social touches are often associated with a hand motion, it is an obvious assumption to make that the handedness affects lateral preferences,” said Ocklenburg. “In emotional situations, the lateral preference shifts to the right. It doesn’t matter if the emotions are positive or negative,” described Packheiser. (IANS)
