This document summarizes Edward T. Hall's cultural factors theory, which identifies key dimensions along which cultures vary, including context, time orientation, territoriality, and use of space. It contrasts low and high context cultures, monochronic and polychronic time, high and low territoriality. For example, low context cultures rely more on verbal communication while high context cultures imply more meaning non-verbally. Monochronic cultures do one thing at a time while polychronic cultures value human interaction over schedules. The document advises paying attention to these cultural differences to better understand others and gain influence across cultures.
