Social information processing theory, also known as SIP, is a psychological and sociological theory originally developed by Salancik and Pfeffer in 1978. This theory explores how individuals make decisions and form attitudes in a social context, often focusing on the workplace. It suggests that people rely heavily on the social information available to them in their environments, including input from colleagues and peers, to shape their attitudes, behaviors, and perceptions. Joseph Walther reintroduced the term into the field of interpersonal communication and media studies in 1992. In this work, he constructed a framework to explain online interpersonal communication without nonverbal cues and how people develop and manage relationships in a computer-mediated environment. Walther argued that online interpersonal relationships may demonstrate the same or even greater relational dimensions and qualities (intimacy) as traditional face-to-face (FtF) relationships. However, due to the limited channel and information, it may take longer to achieve than FtF relationships. These online relationships may help facilitate interactions that would not have occurred face-to-face due to factors such as geography and intergroup anxiety. The term Social Information Processing Theory was originally titled by Salancik and Pfeffer in 1978. They stated that individual perceptions, attitudes, and behaviors are shaped by information cues, such as values, work requirements, and expectations from the social environment, beyond the influence of individual dispositions and traits. Later, they renamed Social Influence model. At the start of the 1990s, after the advent of the Internet and the World Wide Web, interest grew in studying how the Internet impacted the ways people communicate with each other. Joseph Walther, a communication and media theorist, said that computer-mediated communication (CMC) users can adapt to this restricted medium and use it effectively to develop close relationships.
