Language Style Matching Predicts Success in Romantic Relationships


Researchers investigate how similarity in language use, known as language style matching (LSM), and calculated using LIWC, affects romantic relationships. In two studies, natural language samples are analyzed to determine whether LSM predicts outcomes for romantic relationships. The first study examines transcripts of 40 speed dates and finds that greater LSM predicts an increased likelihood of mutual romantic interest. The second study focuses on 86 couples’ instant messages and finds that LSM positively predicts relationship stability at a 3-month follow-up. Overall, LSM appears to reflect implicit interpersonal processes central to romantic relationships.
