This document discusses culture and communication. It defines key aspects of communication like encoding, decoding, and channels. It also discusses how culture influences social cognition, definitions, and nonverbal communication. Intercultural communication is more complex due to differing ground rules between cultures. This can lead to uncertainty, conflict, and issues with context. Barriers to effective intercultural communication include assumptions of similarity, language differences, nonverbal misinterpretations, stereotypes, tendencies to evaluate, and anxiety. Mindfulness, uncertainty reduction, consideration of face, and emotion regulation can help improve intercultural communication.
