Extraversion Word Clouds (IMAGE) University of Pennsylvania Caption To visualize the results of a study that looked a correlations between the language in a group of volunteers' Facebook status messages and their responses to a personality questionnaire, Penn researchers created a series of word clouds. Each summarized the language that statistically predicted a given trait, with the correlation strength of a word in a given cluster being represented by its size. Here, word clouds for extraverts and introverts are compared. More word clouds are available at wwbp.org.
