Social information processing (theory)

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.
