My research focuses on how natural language relates to health, personality, and social behavior in three broad contexts:
- Conversations: Language style matching (LSM) occurs when people match each other's function words (such as if, the, and she). High LSM indicates that conversation partners are socially engaged, or paying attention to each other's words and mental states. In most situations, matching is good: We like and want to keep talking with people who are similar to us and easy to understand. However, some of my recent research shows that focusing on and matching a partner's language use may lead to negative outcomes like impasse in antagonistic conversations.
- Individual language use: This research mainly concerns questions about group-level variables like HIV incidence or personality traits. For example, what speaking styles signal neuroticism, and how do those signals differ in public (e.g., blogs, speeches), private (e.g., diaries, self-talk), and the grey area of social media? In health research, what are the linguistic characteristics of counties that, despite high population density and poverty, have low rates of HIV or sexually transmitted infections?
- Literature: Fiction is an extraordinarily rich data source. In it, we get a glimpse of how the mind works, or how authors (expert and non-expert) believe it works. Most of the time, we find that art imitates life. Men sound more or less like men, women sound like women, people become less self-focused when they're promoted, and so on. But we can also learn from mismatches between life and art and the individual differences that are associated with them.
Almost all of my research uses computerized text analysis. I mainly use the Linguistic Inquiry and Word Count, or LIWC.
