Language style matching predicts relationship initiation and stability.

Previous relationship research has largely ignored the importance of similarity in how people talk with one another. Using natural language samples, we investigated whether similarity in dyads' use of function words, called language style matching (LSM), predicts outcomes for romantic relationships. In Study 1, greater LSM in transcripts of 40 speed dates predicted increased likelihood of mutual romantic interest (odds ratio = 3.05). Overall, 33.3% of pairs with LSM above the median mutually desired future contact, compared with 9.1% of pairs with LSM at or below the median. In Study 2, LSM in 86 couples' instant messages positively predicted relationship stability at a 3-month follow-up (odds ratio = 1.95). Specifically, 76.7% of couples with LSM greater than the median were still dating at the follow-up, compared with 53.5% of couples with LSM at or below the median. LSM appears to reflect implicit interpersonal processes central to romantic relationships.

Vengefully ever after: destiny beliefs, state attachment anxiety, and forgiveness.

Two studies examined how destiny beliefs (that potential relationships are or are not "meant to be") interact with state attachment anxiety to predict forgiveness tendencies. In Study 1, participants experienced an experimental manipulation of attachment anxiety (vs. security) before indicating the degree to which they would forgive a series of hypothetical partner offenses. In Study 2, participants reported every 2 weeks for 6 months (14 waves in total) on offenses enacted by their partner and indicated the degree to which they forgave the partner, both concurrently and 2 weeks later. Consistent with predictions, results revealed Destiny Beliefs x State Attachment Anxiety interaction effects: Strong (relative to weak) destiny beliefs predicted reduced forgiveness tendencies for individuals experiencing state attachment anxiety, but such beliefs were not associated with forgiveness for individuals experiencing state attachment security. Results from Study 2 suggest that this interaction effect was significantly mediated through trust in the partner.
