The words people use in their daily lives can reveal important aspects of their social and psychological worlds. With advances in computer technology, text analysis allows researchers to reliably and quickly assess features of what people say as well as subtleties in their linguistic styles. Following a brief review of several text analysis programs, we summarize some of the evidence that links natural word use to personality, social and situational fluctuations, and psychological interventions. Of particular interest are findings that point to the psychological value of studying particles-parts of speech that include pronouns, articles, prepositions, conjunctives, and auxiliary verbs. Particles, which serve as the glue that holds nouns and regular verbs together, can serve as markers of emotional state, social identity, and cognitive styles.

Three experiments were conducted to determine the psychometric properties of language in dyadic interactions. Using text-analysis, it was possible to assess the degree to which people coordinate their word use in natural conversations. In Experiments 1 (n = 130) and 2 (n = 32), college students interacted in dyadic conversations in laboratory-based private Internet chat rooms. Experiment 3 analyzed the official transcripts of the Watergate tapes involving the dyadic interactions between President Richard Nixon and his aids H. R. Haldeman, John Erlichman, & John Dean. The results of the three studies offer substantial evidence that individuals in dyadic interactions exhibit linguistic style matching (LSM) on both the conversation level as well as on a turn-by-turn level. Furthermore, LSM is unrelated to ratings of the quality of the interaction by both participants and judges. We propose that a coordination-engagement hypothesis is a better description of linguistic behaviors than the coordination-rapport hypothesis that has been proposed in the nonverbal literature.

We propose that sharing a negative-as compared to a positive-attitude about a third party is particularly effective in promoting closeness between people. Findings from two survey studies and an experiment support this idea. In Studies 1 and 2, participants' open-ended responses revealed a tendency to recall sharing with their closest friends more negative than positive attitudes about other people. Study 3 established that discovering a shared negative attitude about a target person predicted liking for a stranger more strongly than discovering a shared positive attitude (but only when attitudes were weak). Presumably, sharing negative attitudes is alluring because it establishes in-group/out-group boundaries, boosts self-esteem, and conveys highly diagnostic information about attitude holders. Despite the apparent ubiquity of this effect, participants seemed unaware of it. Instead, they asserted that sharing positive attitudes about others would be particularly effective in promoting closeness.

Over two decades of research devoted to the writing paradigm has resulted in substantial findings that translating emotional events into words leads to profound social, psychological, and neural changes. How and why would constructing stories about important personal events be so beneficial? The chapter describes the writing paradigm used in this research, offering an overview of the research findings and examination of its historical antecedents. While the precise mechanisms through which a narrative heals are still unrealized, we review three underlying processes that might explain its power: emotional inhibition, cognitive processes, and linguistic processes that echo changes in social orientation. Most recently, advances in computerized text analysis, in addition to the rapid development of the Internet, have afforded a new lens on the psychological transformations achieved through the writing paradigm. Linguistic Inquiry and Word Count (LIWC) is one such computerized text analysis program that captures style and content words. Originally created to better understand the language of emotional upheaval and recovery, with a focus on content and emotional valence, more recent research has focused on subtle stylistic differences in function words such as pronouns, articles, and prepositions. These “junk words” have proven to be reliable markers of demographics, biological activity, depression, life stressors, deception, and status. The chapter briefly reviews recent LIWC-based research regarding the often-overlooked stylistic components of sharing one's story.
