ABSTRACT Communication and language exist as complex and intertwined systems influenced by several overlapping dimensions that cannot be comprehended separately. In this research, the multi-dimensional nature of communication and language is explored using an interdisciplinary approach which considers linguistic aspects, sociocultural background, technological dimension, and cognition. The study employs a sequential mixed methods approach which includes the qualitative analysis of 48 cases of authentic communication (24 instances of face-to-face interaction and 24 examples of digital interaction) and the quantitative survey of 312 participants from three linguistic communities. Findings indicate that technological platforms have the potential to radically alter traditional linguistic norms by emphasizing sociocultural and cognitive components in such a way that hybrid linguistic practices develop. Multimodality, adaptive politeness, code-meshing, and platform-related linguistic features were used by participants in order to accomplish linguistic goals in different contexts of cognitive and sociocultural demands. Results from the factor analysis showed four correlated but independent dimensions that explained 68.4% of the variance, whereas results from multiple regression models showed significant predictors of technological factors on linguistic adaptation (β =.41, p <.001) and sociocultural adaptation (β =.37, p <.001). There was a significant negative correlation between cognitive load and communicative satisfaction in high-stakes intercultural digital communication. This paper points out some research gaps that still exist in terms of examining the combination of these aspects and presents a multidimensional approach. The results can be useful from a theoretical point of view and have several applications. Some limitations regarding the sample size and measuring the cognitive process are discussed.
