The language of extraversion: Extraverted people talk more abstractly, introverts are more concrete

To understand the impact of personality, one needs to know how personality differences manifest themselves in language use. The present study investigates the link between extraversion and language abstraction. Participants’ spontaneous verbal utterances in face-to-face interactions were analyzed for language abstraction by applying the linguistic category model, which distinguishes predicate types that convey information in concrete or interpretative manner. We also applied the Linguistic Inquiry and Word Count (LIWC) program to relate several word categories to extraversion and language abstraction. Results show significant positive correlations between extraversion and both language abstraction and self-reported level of interpretation. Language abstraction was also linked to LIWC variables (e.g., articles, numbers) previously shown to be related to extraversion. The findings suggest that the verbal style of extraverts is characterized by a higher level of abstract interpretation, whereas introverts tend to stick to concrete facts

It is all about being popular: The effects of need for popularity on social network site use

Prior research on predictors of social network site (SNS) use has mainly focused on the Big Five, narcissism, and self-esteem. Results have been inconsistent, and variance explained was rather low. Need for popularity (NfP) might be a better predictor of SNS use, because SNSs are ideal venues for people with a high NfP. Study 1 tested NfP, self-esteem, need to belong, entitlement, and vanity as predictors for a range of SNS behaviors; Study 2 replaced entitlement and vanity with narcissism and added the Big Five as predictors. SNS behaviors assessed were grooming, strategic self-presentation, profile enhancement, disclosure of feelings, routine use of SNS, and number of friends. Results showed that NfP was the strongest and most consistent predictor of SNS behaviors. This pattern indicates that NfP plays an important role in SNSs. © 2012 Mary Ann Liebert, Inc

Playing in or out of character: User role differences in the experience of Interactive Storytelling

Interactive storytelling (IS) is a promising new entertainment technology synthesizing preauthored narrative with dynamic user interaction. Existing IS prototypes employ different modes to involve users in a story, ranging from individual avatar control to comprehensive control over the virtual environment. The current experiment tested whether different player modes (exerting local vs. global influence) yield different user experiences (e.g., senses of immersion vs. control). A within-subject design involved 34 participants playing the cinematic IS drama "Emo Emma
