The lack of nonverbal cues means that computer-mediated communications contain less information than face-to-face communications, however social information processing theory finds that longer and/or more frequent communication while participating in computer-mediated communication help address the issue of information exchange.
The social information perspective assumes that communicators in computer-mediated exchanges are similarly driven to acquire social information that will encourage the development of social relationships as are communicators using other media.
These theories are termed cues filtered-out theories.
Cues filtered-out theories refer to theories that address the lack of nonverbal cues as being detrimental to online relationship development.
Walther's research critiqued past methodological and conceptual problems with theoretical thinking.
He subsequently worked toward establishing an interpersonal communication theory that more accurately reflected the intersection among communication, online environments, the self and relationships.
Two of those theoretical perspective that influenced Walther's theory are social presence theory and media richness theory.
Walther believes that both SPS and MRT suffer from a limited understanding of relational life online.
Thirty-six current members and 27 former members of Japan completed an online survey.
While the term has traditionally referred to those communications that occur via computer-mediated formats (e.g., instant messages, e-mails, chat rooms), it has also been applied to other forms of text-based interaction such as text messaging.
Social information processing theory argues that online interpersonal relationships may demonstrate the same relational dimensions and qualities as Ft F relationships.
Walther's work on the hyperpersonal model is his research that has been most cited by other researchers.
The hyperpersonal model finds that in certain circumstances, computer-mediated communication surpasses the affection and emotion of similar situations of face-to-face interpersonal communication.
While other media theories exist, such as media richness theory and uses and gratifications theory, SIP specifically focuses on relationships entirely mediated online.
