Social psychologist
= Social psychologist
A <social psychologist> studies how social information and interactions influence <cognition>, <emotion> and <behavior>. Controlled experiments can vary a social cue while measuring another person’s response. Negotiation studies, for example, separate the <emotion> communicated by a partner from the observer’s own feeling and subsequent concession. This makes social influence an empirically testable relation rather than an explanation inferred merely because two people behaved similarly. <The interpersonal effects of anger and happiness in negotiations by Gerben A. van Kleef and others>[2004, emotion information and negotiation responses]{ref}
