Talk about Yourself on Social Media?
New Study Published by Scientists at Freie Universität and the Max Planck Institute for Human Cognitive and Brain Sciences Reveals Brain Network for Sharing Self-related Information on Facebook
№ 061/2016 from Mar 07, 2016
A network of brain regions involved in self-disclosure on Facebook has been determined, according to a new study published in the open-access journal Scientific Reports. In the first study to examine the intrinsic functional connectivity of the brain in relation to social media use, Dr. Dar Meshi and colleagues from Freie Universität Berlin and the Max Planck Institute for Human Cognitive and Brain Sciences in Leipzig observed connectivity between regions of the brain previously established to play a role in self-cognition, in 35 participants. Researchers focused on the medial prefrontal cortex and the precuneus, two cortical midline regions that are recruited when thinking about oneself.
“Human beings like to share information about themselves. In today’s world, one way we’re able to share self-related information is by using social media platforms like Facebook,” says Meshi, lead author of the paper and a postdoctoral researcher at Freie Universität, Berlin, Germany.
Facebook is the world’s largest social media channel with 1.5 billion monthly active users. It was used in the study because people post information about their thoughts, feelings, and opinions, as well as pictures and videos of themselves.
All subjects completed a Self-Related Sharing Scale to determine how frequently each subject posted pictures of themselves, updated their profile information, and updated their status. The participants were selected to vary widely in their Self-Related Sharing Scale scores.
Researchers recorded functional neuroimaging (fMRI) data while subjects were allowed to let their mind wander; subjects did not perform an explicit task. Researchers then analyzed the connectivity of each participant’s brain to determine a relationship between brain connectivity and Self-Related Sharing Scale score across participants.
Results showed that participants who share more about themselves on Facebook had greater connectivity of both the medial prefrontal cortex and precuneus, to the dorsolateral prefrontal cortex. There was also greater connectivity between the precuneus and the lateral orbitofrontal cortex.
“Our study reveals a network of brain regions involved in the sharing of self-related information on social media,” says Meshi. “These findings extend our present knowledge of functional brain connectivity, specifically linking brain regions previously established to function in self-referential cognition to regions indicated in the cognitive process of self-disclosure.”
The authors point out that the implications of their research are broad and lay the foundation for future scientific investigation into self-disclosure.
The study was supported by the Excellence Initiative of the German Federal Ministry of Education and Research and was carried out at the Languages of Emotion Research Center at Freie Universtität.
