Previous studies indicate that characteristics of social-based technologies (STs) stimulate the sharing of intimate information online, which in turn enhances the quality of friendships. In addition, intimate online self-disclosure has been positively associated with offline self-disclosure. One objective of the current study was to combine the literature and test a model which postulates that STs use stimulates online self-disclosure which facilitates offline self-disclosure and, thereby, enhances the quality of close friendships. A second objective of this study was to examine if the aforementioned model applies to two categories of STs, including socially interactive technologies (SITs; e.g., instant messaging) and socially passive technologies (SPTs; e.g., reading posts on social networking sites). An online survey was conducted with 212 young adults between 18 and 25 years of age. The proposed indirect positive effects of SITs and SPTs use on the quality of friendships were supported. The positive effect of SITs use on the quality of friendships was explained entirely by the young adults' disclosure of personal information when using SITs which facilitated intimate self-disclosure during face-to-face interactions. Although there was not a direct effect of SPTs use on the quality of friendships, SPTs use was positively related to SPTs self-disclosure, which had a positive effect on offline self-disclosure. The current study enhances our understanding regarding the positive effects associated with the use of STs among close friends and identifies the contribution of online self-disclosure for offline interactions.

Word meanings are not always parallel across languages, and second language (L2) learners often use words in non-native ways. Is the learning problem inherent in maintaining conflicting word-to-meaning mappings within an integrated lexical network, or is it due to insufficient attention to and input for acquiring L2 mappings? To help discriminate between these possibilities, we gave English speakers repeated exposures to 40 brief videos of actions, labeled with five novel words that cross-cut English labeling patterns. Half the participants were told only to learn the labels for the actions. The other half were told to figure out their meanings, which might differ from English. The Figure Out Meanings group made test choices faster and were also slightly more likely to produce definitions capturing the intended meanings. However, both groups performed well above chance in generalizing the novel words. High levels of choice performance for both groups point to insufficient input, rather than inherent properties of lexical networks, as the critical limiting factor in more typical L2 learning contexts. Speed and definition performance hint at some advantage to explicit attention in sorting out L1-L2 differences.

The overall objective of the proposed chapter is to increase the reader's understanding of the role that social media plays in self-disclosing information about ourselves in the development of friendships and identity, as well as explore these themes in a clinical context. As such, readers will gain knowledge regarding the relations between self-disclosing on social media sites and the ensuing friendship and identity development that occurs, the extension of the research findings to clinical populations, and the questions that still remain unanswered. This information may be useful for the advancement of research, policy development, mental health programs, parenting, and education.

Facebook use has implications for subjective well-being. Previous research has revealed that passive Facebook use is typically related to deficits in subjective well-being, which is thought to be linked through upward social comparison. In contrast, active Facebook use is typically related to enhancements in subjective well-being. The main objective of the present study was to synthesize findings related to Facebook use and subjective well-being and to expand by proposing and testing whether the benefits associated with active Facebook use compensate for the negative effects associated with passive use. The second objective was to discuss policy and research directions. A total of 310 undergraduate students completed an online survey with questions regarding Facebook use, social comparison, and subjective well-being. Bootstrapping analyses revealed that active Facebook use did not buffer the negative effects for subjective well-being that occur during passive Facebook use. Recommendations for future research and education programs are discussed.
