Words charged with a positive emotional content are used more frequently, thus enhancing human communication.
Scientists at ETH Zurich have studied the use of language, finding that words with a positive emotional content are more frequently used in written communication. This result supports the theory that social relations are enhanced by a positive bias in human communication. The study by David Garcia and his colleagues from the Chair of Systems Design is published in the first issue of the new SpringerOpen journal EPJ Data Science, and is freely available to the general public as an Open Access article.
Previous studies focused on word lengths and frequency. They demonstrated that frequency depends on the length of words used, as a result of the principle of least effort influencing the use of shorter words. In contrast, this study focused on how the emotions expressed in words relate to the word frequency and its information content. The authors focused on words used in written emotional expression in the three most popular European languages online: English, German and Spanish.
