Professor Namkee Park's research lab specializes in understanding the social and psychological dimensions of digital technology adoption and use in educational, interpersonal, and public health contexts. The lab focuses on how individuals perceive, adopt, and are influenced by emerging communication technologies, integrating theories such as the Technology Acceptance Model (TAM), uses and gratifications, and media richness theory. Key research directions include technology acceptance, social media use and well-being, and the role of multi-channel communication in crisis situations. The lab employs quantitative survey methods to explore the interplay between user motivations, perceived attributes of technology, and behavioral outcomes.

This study examines the factors that influence instructors’ adoption and use of an Internet-based course management system and tests the applicability of the Technology Acceptance Model (TAM), introduced byDavis (1986), in the context of e-learning practices in higher education. Using data from an online survey of a university’s instructors (N = 191), a path analysis revealed that perceived ease of use of the system had a significant impact on perceived usefulness as the TAM suggested. In additi
This study examines factors influencing adoption and use of computer-based voice over Internet protocol (VoIP) phone service and attempts to integrate 2 theoretical approaches: the technology acceptance model (TAM) and the uses and gratifications framework. Using data from an online survey of VoIP users (N = 420), structural equation modeling analyses revealed that perceived ease of use had a significant impact on perceived usefulness. In addition, perceived usefulness had a positive effect on a
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 sign
Previous studies have demonstrated the role of social networks, social capital, and social support in individuals' well-being. However, the ways in which these related constructs simultaneously influence one's well-being outcomes and relate to one another have not been closely examined. This study pays particular attention to the structural characteristics of personal networks, distinction between offline and online social capital, and different indicators of well-being outcomes. Based on survey
The present study examined the factors associated with individuals' use of three different text-based communication media: e-mail, cell-phone texting, and Facebook Wall postings. Three theoretical perspectives, including media richness theory, uses and gratifications, and perceived network effects, were examined. Using data from a survey of college students (N=280), the study found that the theoretical constructs from these theories play different roles when applied to different technologies. Th
