This document discusses social styles and gender differences in communication. It introduces four social styles - analytical, amiable, driver, and expressive - which are based on levels of assertiveness and responsiveness. Each person has a dominant style that can be flexed to communicate more effectively with others. The document also explores existing research on gender differences in areas like the use of talk, humor, conflict resolution, interruptions, and gossip, noting these as cultural differences rather than hard rules. Understanding social styles and gender differences can help improve communication skills.
