Naturalistic Observation of the Relationship Between Music and Self-Esteem

This observational study will be focused on the relationship between music and self-esteem. Is the person listening to music or not? Which can either be identified by wearing headphones or music playing out loud. If they are listening to music that is a score of 1. If they aren't listening to music, that would correlate to a score of 0. Then for each participant measure how long within the 2 minutes the participant sits with an open posture (shoulders back) in seconds. There is a positive relationship between people who are listening to music or not, observed by whether they are wearing headphones or not, and self-esteem.
