An overview of the links between small words and psychological state.
Pennebaker discusses his recent book on language and psychology.
Is a linguistic lie detector possible? The use of first person singular pronouns (I, me, my) can be powerful predictors of telling the truth.
Sometimes, I-words reveal lying in unexpected ways. The use of a linguistic device called a "performative" can signal when a person is about to be deceptive.
Pronouns, articles, and other function words can tell us about people's personalties. Men and woman use words differently in ways that tells us how they think and interact with their worlds.
When people are in a group, the ways they use function words can tell us what their roles are. Leaders use pronouns differently from followers. Groups that get along well have a linguistic fingerprint that is very different from a group that doesn't work welltogether.
Pennebaker describes how certain classes of words can be used to detect truth and deception.
When two or more people are talking with or writing to each other, it is possible to determine how well they are clicking with each other using text analysis methods. We can predict if a couple will go out on a date before they do and who will still be dating several later by looking at the ways they use words with each other.
Part of the UT-Austin psychology series, Pennebaker discusses how writing about emotional upheavals can boost mental and physical health.
