An international research team suggests that humans are hardwired to favour leaning to the right while kissing their romantic partners, which may have wider implications for neuroscience and cognitive sciences.
“According to the new academic study, just published in the journal Scientific Reports, over two-thirds of the kiss initiators and the recipient of the kiss have a bias to turn their heads to the right and men were about 15 times more likely than women to initiate kissing.”
“Psychologists and neuroscientists at the universities of Bath Spa and Dhaka, Bangladesh, invited 48 married couples to kiss privately in their own homes, and after kissing they were asked to go to different rooms, open an envelope and then report on various aspects of the kiss independently of each partner.”
“The setting for the study was significant as kissing in Bangladesh is not typically observed in public and may censored from television or films. That means similar results from the western countries could be attributed to cultural factors or having learnt how to kiss through influences on TV or film.”
“According to a press release on Monday, building on the previous studies from western countries, which have involved couples kissing in public places, the new study is the first to investigate an inherent bias for turning the head to one side while people kiss in a non-western context. And it is also the first study in the world to show that the kiss recipients have a tendency to match their partners’ head-leaning direction.”
“Head turning is one of the earliest biases seen in development – even in the womb a preference for turning the head to the right is observable before that of favouring the right hand or foot. Whether this fundamental bias is innate and extends into adulthood is a lingering question for neuroscience and psychology,”
Dr Rezaul Karim, lead author from the Department of Psychology at the University of Dhaka
“The new research suggests that the act of kissing is determined by the brain splitting up tasks to its different hemispheres. Different hormone levels in each hemisphere and neurotransmitters might be unevenly distributed to each hemisphere as giving rise to a bias to turn right, researchers say.”
I have little, VERY little, memories of my childhood or adolescence – or adulthood for that matter. It concerned me when a therapist colleague said that was an indication of repressed memory of probably horrible childhood trauma. Ai yiiii yiiiiii. Maybe I was beaten, or worse, and all these years believing I had nice parents.
I told a psychiatrist friend about my memory “affliction” thinking he would suggest decades of psycho-analysis at best and in-patient treatment at worst. He looked passively at me and without the slightest hesitation said, “All that indicates is your childhood was boring.”
This is one of my aha moments that I DO remember and spurred me to investigate the neuro-biology of emotion. What does that have to do with hang-over? Read on!
Hung Over by Peggy
You already know without a doubt that most of your memories are ones that were highly emotional experiences.
“Emotional experiences can induce physiological and internal brain states that persist for long periods of time after the emotional events have ended, a team of New York University scientists has found. This study, which appears in the journal Nature Neuroscience, also shows that this emotional “hangover” influences how we attend to and remember future experiences.”
“How we remember events is not just a consequence of the external world we experience, but is also strongly influenced by our internal states–and these internal states can persist and color future experiences,” explains Lila Davachi, an associate professor in NYU’s Department of Psychology and Center for Neural Science and senior author of the study.”
“‘Emotion’ is a state of mind, . . . findings make clear that our cognition is highly influenced by preceding experiences and, specifically, that emotional brain states can persist for long periods of time.”’
” . . . data showed that the brain states associated with emotional experiences carried over for 20 to 30 minutes and influenced the way the subjects processed and remembered future experiences that are not emotional.”
“We see that memory for non-emotional experiences is better if they are encountered after an emotional event,” observes Davachi.
I’m so relieved! Not only wasn’t I beaten . . . or worse . . . the biggest hang-over I’ve experienced was the news I’ve led an exceptionally boring life.
