This document discusses different approaches and models of intercultural communication (ICC). It describes Baldwin's model of ICC, which examines communication along three dimensions: interpersonal, intergroup, and intercultural. It also outlines Gudykunst's approach, which identifies four filters that influence communication: cultural, sociocultural, psychocultural, and environmental. Finally, it summarizes Samovar and Porter's model, which notes that cultures vary in their differences, individuals are not representatives of entire cultures, and culture shapes message processing and creation.
