Study: Body posture affects confidence
The results show how our body posture can affect not only what others think about us, but also how we think about ourselves, said Richard Petty, co-author of the study and professor of psychology at Ohio State University.
"Most of us were taught that sitting up straight gives a good impression to other people," Petty said. "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."
