A group of researchers used karaoke performances to induce embarrassment in young women, monitoring their brain activity and blushing response to understand the mechanisms behind blushing. Prior studies also used similar methods to elicit emotional responses from participants.
The study aimed to investigate the age-old question of why humans blush, with theories ranging from feeling exposed in social situations to concerns about appearance. Researchers challenged Darwin's belief that blushing is primarily due to self-awareness by presenting new findings.
