ABSTRACT
This chapter extends the use of the personal position repertoire beyond the psychotherapy domain, adopting it as a research method applied to the psychology of communication. The aim is to investigate the features of short message system (SMS) communication in a sample of late adolescents. Mobile phones are gradually becoming one of the most important new media. From a pragmatic point of view, mobile phones reshape the features of interaction, as SMS communication allows a more private and discrete reading and a more reflexive reply. SMSs are short texts that contain only 160 characters. The chapter focuses on a research which aims at showing the discursive modalities through which the dialogical self emerges from the communicative interactions developed in SMS messages. The dialogical construction of the self in SMS communication seems to push the enunciators to think about themselves through the interlocutor they are sending the message to.
