Previously, competence was conceptualized as a static individual construct that could be measured with regard to grammatical, sociolinguistic, pragmatic, and discursive dimensions of second language (L2) knowledge. This perspective was criticized with the emergence of constructivist views in second language acquisition (SLA), and interaction was assumed to be coconstructed in specific contexts by all the members of the group, and was referred to as interactional competence. This study aimed at investigating the highlighted features of interactional competence from raters point of view. The raters were also required to compare and contrast the differences between the performance of paired vs. group interactions. For this purpose, 16 male and female proficient English language and literature students of Shiraz university participated in the study; also, 10 experienced raters were chosen to rate the performances. The participants were given a set of controversial questions, once to argue their viewpoints in four-member groups, and once more in paired interaction. Having videotaped the discussions, the raters were asked to watch the clips and were interviewed to comment their perspective. The detailed analysis of the transcription of interviews revealed at least three aspects of interactional competence, each with some subcategories: management, engagement and attention, and paralinguistic aspects. Moreover, peer-to-peer interactions were filled with turn-taking, other-initiated self-repair, use of pauses and wait times, backchanneling, and facial features such as eye contact. Group performances were prominent with self-initiated self-repair, open-ended clarification requests, and employment of vocal features.
