Social Information Processing Theory (SIP) explains how people communicate and form relationships in online environments. Developed by Joseph Walther in the 1990s, the theory suggests that individuals can develop meaningful connections through digital communication, despite the lack of nonverbal cues present in face-to-face interactions. The theory posits that users adapt their communication styles to compensate for the absence of physical presence. Over time, online interactions can lead to the same level of intimacy and understanding as traditional, in-person relationships, as individuals use text-based messages to convey emotions and intentions effectively.
