Abstract

This article examines how a semiotic model can show symbolic mediation between sign-event and life-event through symbol-mediated interpreting activity, introduces the Vygotskyan concept of symbol, and thus contributes to overcoming the demarcation between dyadic and triadic conception of symbol Three types of semiotic model are introduced: a representational semiotics, an indicative semiotics, and an activity-semiotics. The three systems are correlated in a triad and, in particular, activity semiotics is positioned as Peircean symbol in a Third, mediating representational structure with indicative structure. In relation to mediation and interpretation, a dialogic process of sign relations is discussed: icon, index, and symbol, through which indexical signs are emphasized, enabling the symbolic structure to be dynamic.
