Researchers investigated the neural substrates and mental processes underlying blushing in response to self-observation.

By Vijay Kumar MalesuReviewed by Danielle Ellis, B.Sc.Jul 22 2024 In a recent study published in the Proceedings of the Royal Society B: Biological Sciences, a group of researchers investigated the neural substrates and mental processes underlying blushing in response to self-observation.

Out of 63, 49 participated in the MRI session; others were ineligible due to factors like piercings or Intrauterine Devices . Nine were excluded due to Functional MRI data errors, leaving 40 participants . One participant had missing cheek temperature data, and another had missing self-reported embarrassment data. Participants were compensated with travel expenses and 30 euros or three student credits.

The Self-viewing condition elicited the highest blushing response , while the Professional condition showed a slight decrease in temperature, and the Other condition showed no significant change. Paired tests within the model confirmed that blushing responses were significantly higher in the Self condition compared to the Professional condition .
