Age differences in perceptions of online community participation among non-users: An extension of the Technology Acceptance Model

This study examined age differences in perceptions of online communities held by people who were not yet participating in these relatively new social spaces. Using the Technology Acceptance Model (TAM), we investigated the factors that affect future intention to participate in online communities. Our results supported the proposition that perceived usefulness positively affects behavioral intention, yet it was determined that perceived ease of use was not a significant predictor of perceived usefulness. The study also discovered negative relationships between age and Internet self-efficacy and the perceived quality of online community websites. However, the moderating role of age was not found. The findings suggest that the relationships among perceived ease of use, perceived usefulness, and intention to participate in online communities do not change with age. Theoretical and practical implications and limitations were discussed.

Effects of self-disclosure on relational intimacy in Facebook

The present study examined the association between self-disclosure and intimacy in the context of Facebook. As the antecedents of self-disclosure, the study included the need for affiliation and the motivations for relationship maintenance and initiation. Using data from an online survey (N=249), structural equation modeling analyses revealed that self-disclosure amount and positivity were positively associated with intimacy, while self-disclosure honesty and intent were not associated with intimacy. The study also found no direct association between the need for affiliation and self-disclosure. Rather, the need for affiliation was associated with the motivations for relationship maintenance and initiation, which in turn affected self-disclosure and intimacy. The theoretical implications of the study were discussed.

Strategic misrepresentation in online dating: The effects of gender, self-monitoring, and personality traits:

This study examines factors (including gender, self-monitoring, the big five personality traits, and demographic characteristics) that influence online dating service users’ strategic misrepresentation (i.e., the conscious and intentional misrepresentation of personal characteristics). Using data from a survey of online dating service users (N = 5,020), seven categories of misrepresentation — personal assets, relationship goals, personal interests, personal attributes, past relationships, weight, and age — were examined. The study found that men are more likely to misrepresent personal assets, relationship goals, personal interests, and personal attributes, whereas women are more likely to misrepresent weight. The study further discovered that self-monitoring (specifically other-directedness) was the strongest and most consistent predictor of misrepresentation in online dating. Agreeableness, conscientiousness, and openness also showed consistent relationships with misrepresentation.

Understanding Online Community Participation : A Technology Acceptance Perspective

Online community participation has not been well understood from the perspective of technology adoption and use. Using a national sample of 537 online community participants in the United States and structural equation modeling, this study demonstrates that the technology acceptance model (TAM) can provide a useful foundation for theoretical explanation. By empirically testing the original TAM and comparing it with an alternative model, our results confirmed that perceived usefulness (PU) outweighs perceived ease of use (PEOU) in explaining actual use. Our final model further suggested a feedback loop between PU and PEOU, which significantly improved the model fit at both global and local levels. In addition, three exogenous variables (i.e., Internet self-efficacy, community environment, and intrinsic motivation) were proposed and validated. These findings have clear implications for the structure of the TAM as well as for its usefulness for the newly burgeoning practice of online community participation.

Can a Robot Be Perceived as a Developing Creature? Effects of a Robot's Long-Term Cognitive Developments on Its Social Presence and People's Social Responses toward It

This study tests the effect of long-term artifi cial development of a robot on users’ feelings of social presence and social responses toward the robot. The study is a 2 (developmental capability: developmental versus fully matured) x 2 (number of participants: individual versus group) between-subjects experiment (N = 40) in which participants interact with Sony’s robot dog, AIBO, for a month. The results showed that the developmental capability factor had signifi cant positive impacts on (a) perceptions of AIBO as a lifelike creature, (b) feelings of social presence, and (c) social responses toward AIBO. The number of participants factor, however, affected only the parasocial relationship and the buying intention variables. No interaction between the two factors was found. The results of a series of path analyses showed that feelings of social presence mediated participants’ social responses toward AIBO. We discuss implications of the current study on human–robot interaction, the computers are social actors (CASA) paradigm, and the study of (tele)presence.

Individuals' personal network characteristics and patterns of Facebook use: A social network approach

Using the theoretical framework of ego-centric networks, this study examines the associations between the characteristics of both Facebook-specific and pre-existing personal networks and patterns of Facebook use. With data from an ego-network survey of college students, the study discovered that various dimensions of Facebook-specific network characteristics, such as multiplexity, proximity, density, and heterogeneity in race, were positively associated with usage patterns, including time spent on Facebook, posting messages, posting photos, and lurking. In contrast, network characteristics of pre-existing relationships, such as density and heterogeneity in race, were negatively associated with Facebook usage patterns. Theoretical implications and limitations were discussed.

College Students' Motivations for Facebook Use and Psychological Outcomes

Based on the uses and gratifications framework, this study examined associations between motivations for using Facebook among college students, their concern for impression management, Facebook intensity, and psychological outcomes including sense of belonging and satisfaction with campus life. Using data from an online survey (N = 246), the study found that four motivations—entertainment, relationship maintenance, self-expression, and communication—together with impression management, were significantly associated with Facebook intensity. However, the impacts of Facebook intensity on psychological consequences were relatively limited. Theoretical implications of the study were discussed.

Intention to upload video content on the internet: The role of social norms and ego-involvement

This study examined the factors that are associated with peoples intention to upload video content online within the framework of the theory of planned behavior (TPB). Using data from a survey of college students (N=241), structural equation modeling analyses revealed that individual descriptive norm is associated with the intention to upload video content online. In addition, ego-involvement played an essential role in accounting for both attitude toward the uploading behavior and the intention to upload. These findings suggest that integration of the constructs of the TPB, social norms, and ego-involvement can be a fruitful theoretical endeavor for understanding peoples intention to upload video content online. The theoretical implications and limitations were discussed.

Social comparison on Facebook

Previous studies have investigated the role of social comparison on Facebook. The social comparison process occurring on Facebook and its impacts, however, has not been fully captured. Thus, the present study examined the associations among Facebook use, social comparison orientation on Facebook (SCOF), and psychological outcomes represented by perceived social support and mental health. Also, the role of self-esteem and impression management was explored as antecedents of SCOF. Using a sample of college students (Nź=ź313), the study found a positive association between Facebook use and SCOF. Facebook use was positively associated with perceived social support, yet it was not significantly associated with mental health. The study also found a negative association between SCOF and mental health. However, there was no significant association between SCOF and perceived social support. Finally, both self-esteem and impression management were positively associated with SCOF. Theoretical implications were discussed. This study examined the association between Facebook use and social comparison.Facebook use was positively associated with perceived social support.There was a negative association between social comparison and mental health.Self-esteem was positively associated with social comparison on Facebook.

Linking Cultural Capital With Subjective Well-Being and Social Support

This study examines the ways in which different forms of cultural capital are associated with college students’ subjective well-being and social support. Results show that when social capital is accounted for, cultural capital derived from sports participation was positively associated with subjective well-being and social support. Further, the size and density of discussion networks about culture were positively associated with well-being and social support in general, while the heterogeneity of networks was negatively related. Findings from this study extend previous research on cultural capital by (1) drawing attention to the inclusive aspect of cultural capital, (2) examining online cultural participation as well as multiple forms of cultural activities including popular and sporting events, (3) applying the literature on interpersonal discussion networks to the context of culture and demonstrating the value of communicative action about cultural experiences, and (4) understanding the implications of cultural capital in a college setting.
