The process school of communication leans heavily on (A) Linguistics (B) Applied arts (C) Semiotics (D) Social sciences Correct Ans: (D) Explanation: The process school of communication focuses on how messages move between senders and receivers. It emphasizes cause-and-effect relationships in communication. This approach studies how people encode, transmit, and decode messages in different contexts. Since it examines human interactions, the process school leans heavily on social sciences. Social sciences, including psychology, sociology, and anthropology, help explain how individuals and groups communicate. These disciplines analyze behavior, perception, and societal influences on communication. For example, this approach explores how body language, tone, and words impact understanding. It also studies feedback loops, where the receiver’s response shapes future communication. Advertisers, educators, and media professionals use these principles to craft effective messages that influence audiences. Moreover, the process school contrasts with the semiotic school, which focuses on signs and symbols. Instead of analyzing meaning in texts, the process school studies the mechanics of communication, such as noise, channels, and message clarity. In conclusion, the process school of communication depends on social sciences because it seeks to understand human interaction and message transmission. It remains a vital framework for effective communication strategies in media, marketing, and interpersonal exchanges.
