This presentation demonstrates how the concept of contact in Roman Jakobson's six-function schema can be reinterpreted from the perspective of indexicality to extend the model for understanding asynchronous communication mediated by media. The six-function schema, which includes telephone-mediated communication as a model, presupposes real-time communication, and thus, the element of contact is understood within the context of synchronous message transmission and reception. However, asynchronous communication is prevalent in reality. The original schema, based on synchronous premises, cannot adequately account for the uncertainties associated with asynchronous communication. Considering the concept of contact from the perspective of the notion of index, it becomes possible to introduce an asynchronous factor into the six-function schema.
Jakobson defined shifters as indexical symbols possessing both the dimension of symbols articulated by convention and the dimension of indexicals that maintain an existential relationship with their objects. In this framework, indexicals anchor symbolically constructed propositions to contexts, enabling specific references to real-world objects. Anthropological linguist Michael Silverstein reinterpreted Jakobson's theory of shifters from the perspective of contiguity with the cognition of sign tokens. For instance, Jakobson positioned the past tense as the referential relationship between the speech event and the event being narrated. In contrast, Silverstein linked the speech event to the cognition of sign tokens by the recipient at a given speech time, repositioning the function of indexicals in terms of contiguity from this cognitive moment. This anchoring specifies the context for understanding the speech event.
However, as Silverstein's model focuses on face-to-face, real-time communication, the potential found in anchoring the function of indexicals to the cognition of sign tokens was not fully explored. In real-time communication models, the speech event and its cognition are fundamentally simultaneous. In contrast, applying this concept to a model of écriture that includes transmission delays allows for consideration of cases where the speech act occurs without the immediate cognition of the sign tokens. This scenario offers an understanding of sign tokens in a potential state, lacking the context-specific trigger of cognition.
Overlaying this understanding onto the six-function schema reveals a scenario where the sender, message, and code are materialized, but contact, in the form of sign token cognition, has not occurred, leaving the receiver and context in a potential state. By repositioning contact as an independent event of sign token cognition, the six-function schema can be adapted for asynchronous communication.
