According to a new study published in the British Journal of Psychology, poor posture can affect your decision making, too. So what happens when subjects adopt expansive or contractive postures on their own? For some, the tablet was placed flat on a tabletop, forcing them to hunch over (the contractive group). For others, it was placed on a stand that required them to take a more upright posture (the expansive group). In their questionnaires, the expansive posture group reported feeling more pride than the contractive group as well.
