The present study aims at examining the similarities and differences in the published research article abstracts between native(NS) and non-native English speakers(NNS). Using the comparative analysis of two corpora, the study compares the top 10 most frequently used key words and concordance lines shown in each corpus and analyzes the two groups’ different perceptions, study foci, issues, and lexical choices. The results of the study reveal that NS and NNS have different thematic interests, issues they are dealing with, and perceptions about their English, English teaching, and learning in the abstracts of published articles. Even though the study has relatively a small data set, it provides empirical evidences for the assumption that NS and NNS have different perceptions, interests, and issues dealt with in research article abstracts.
