Capturing personality traits with psychological Al
The frequency with which we use certain words and word combinations reveals something about our personality. This connection, which many would assume is intuitive, has already been shown and replicated in many scientific studies. In the development of our 100 word analysis, numerous psychological studies were considered in which experienced researchers from different disciplines were involved. Especially the American social psychologist, J. Pennebaker, contributes immensely to the understanding of the connection between language and personality.
Through his work, we know that it is the seemingly unimportant function of certain words (e.g. personal pronouns or articles) which reveal the most about a person. Functional words are sentence-logical elements that do not transport content. They are rather structural content words, thus giving them a linguistic framework. In the following examples we will demonstrate how the linguistic structure reveals something about a persons personality.
How people think – analytically or intuitively – is reflected in their use of function words. For example, people with an analytical way of thinking increasingly use function words which give their language accuracy, such as articles or prepositions. Researchers discovered this connection by examining application letters from students.
The dominance of a person can also be determined through language. Several studies have investigated how dominant people use language in comparison to other study participants.
Some findings point to a connection between depression and language. Repeated studies have shown that the personal pronoun "I" is more often used by depressed participants than those not suffering from depression.
Capturing emotions with psychological AI
The use of words reveals something about a persons current emotional state: Are they sad, angry or happy at the moment? Initial, emotions can be divided into positive and negative valences. In addition, negative emotions in particular can be further subdivided, with the most relevant negative emotions being grief, anger and fear. Moods and feelings, on the other hand, seem to be expressed through so-called content words.
