So happy together: Deconstructing the right brain / left brain myth

A blog post co-written by psychotherapist Dr Ana Kozomara-Lund and social neuroscientist Dr Pascal Vrticka on the pervasive “left brain versus right brain” myth.

Main take home message
The “right brain” versus “left brain” concept intuitively resonates with many people’s self-perceived strengths and weaknesses. It offers a tangible explanation for understanding personality and cognitive styles and their underlying neurobiological mechanisms – including in a therapeutic setting. However, the concept’s underlying assumptions are not supported by current neuroscientific evidence.

Hence, we should not continue to promote a myth that has already been debunked many times just for the sake of its simplicity and user-friendly nature. What we should do instead is to refer to more appropriate and up-to-date neuroscience explanations, even if they are less intuitive and more complicated. It is really worth it and many people, including the two authors, are very happy to help and provide support along the way.

Dr Pascal Vrticka is a social neuroscientist with strong ties to developmental & social psychology. His research focuses on the psychological, behavioural, biological, and brain basis of human social interaction, attachment and caregiving. Besides measuring neurobiological responses to different kinds of social versus non-social information in single participants using (functional) magnetic resonance imaging ([f]MRI) and electroencephalography (EEG), Dr Vrticka most recently started to assess bio-behavioural synchrony in interacting pairs using functional near-infrared spectroscopy (fNIRS) hyperscanning. The main question thereby is how romantic partners and parents with their children get “in sync” when they solve problems together or talk to each other. Dr Vrticka furthermore relates the obtained individual and dyadic behavioural, biological, and brain measures to interindividual differences in relationship quality – particularly attachment and caregiving. In doing so, he refers to attachment theory that provides a suitable theoretical framework on how we initiate and maintain interpersonal relationships across the life span. With his research, Dr Vrticka is promoting a new area of investigation: the social neuroscience of human attachment.
