This research project deals with the social determination of communicative competence against the background of current developments in the field of media as well as cultural and societal changes (e.g. mediation, mediatization). Starting with an interdisciplinary discussion of approaches to media socialization and the domestication of media theoretical roots as wel as the evolution of discourses on communicative competence are analysed. Relying thereon concepts of media competence and media literacy are compared and discussed with regards to current media developments and societal challenges with the objective of uncovering influencing factors for an individual’s composition of media literacy (closely relating to its communicative competence). This theoretical approach is supported by empirical research on young audiences.
