Power in interpersonal relationships influences who we choose as friends and partners and determines dependence within those relationships. Those with less dependence have more power. Cultures vary in attitudes towards power dynamics between groups. Power can come from expertise, ability to reward or punish, and persuasiveness. It is communicated through speech, nonverbal cues, listening skills, and strategies for gaining or resisting compliance from others. Empowering others increases their power within a relationship.
