New Delhi:
Kiss is the most special way to make your partner fell how much you love him/ her. But did you know this earler that more than two-thirds of humans generally tend to tilt their heads in the right side when kissing.
A recent study found the above finding in research. It also added that men are more likely to initiate a kiss as compared to women.
More than two-thirds of the kiss initiators and kiss recipients turn their heads to the right at time of lip-locking. The study also found that the kiss recipients also tend to lean in the same direction as their partner so that they can avoid the discomfort of mirroring heads.
The findings suggest that the act of kissing is determined by the brain's procedure of dividing the task to two different hemispheres- similar to being either right or left handed- particularly the function in the left cerebral hemisphere which is placed in the emotion and decision-related areas of the brain.
The researchers name the presence of different hormone levels (like testosterone) in each hemisphere and neurotransmitters' uneven distribution in each hemisphere (like dopamine, involved in reward behaviours) as reason behind turning to right.
"This is the first study to show sex differences in the initiation of kissing, with males more likely being the initiator and also that the kiss initiators' head-turning direction tends to modulate the head-turning direction in the kiss recipients," Dr. Rezaul Karim from University of Dhaka added.
Another author Dr. Michael Proulx from the University of Bath explained that the study gives us a seak peek into the private behaviour in a private cuture with implications for all people
