Your mother may have been right when she told you to sit up straight: New research suggests that good posture could make you feel more confident about your thoughts.
"Most of us were taught that sitting up straight gives a good impression to other people," Richard Petty, co-author of the study and a psychology professor at Ohio State University in the US, said in a university news release. "But it turns out that our posture can also affect how we think about ourselves. If you sit up straight, you end up convincing yourself by the posture you're in."
The researchers, whose findings appear in the European Journal of Social Psychology, enlisted 71 Ohio State students for their study. They were told to sit up straight and push out their chest, or to slouch. The students were then asked about the positive or negative traits they'd show as a hypothetical future employee.
"Their confident, upright posture gave them more confidence in their own thoughts, whether they were positive or negative," Petty stated. "People assume their confidence is coming from their own thoughts. They don't realise their posture is affecting how much they believe in what they're thinking. If they did realise that, posture wouldn't have such an effect."
The findings are similar to those in a previous study that found that people who nodded their heads had more confidence in their thoughts than those who shook their heads back and forth.
In a similar experiment involving different students, "participants didn't report feeling more confident in the upright position than they did in the slouched position, even though those in the upright position did report more confidence in the thoughts they generated," Petty said. - (HealthDay News, November 2009)
