This paper examines whether overconfidence can explain the relationship between performance and behavior of investors in Taiwan. Different from prior research that used a specific sample of individuals trading records, this work focuses on aggregate investor behavior to know whether overconfidence is a market-wide phenomenon. It is found that overconfident investors will trade more aggressively, and the excessive trading of overconfident investors results in the observed excessive market volatility. However, overconfidence effect exists only following bull markets. After a period of stock gains, overconfident traders tend to title their investment toward smaller-cap and growth stocks, consistent with the prediction of overconfident hypothesis that as investors become overconfident, they underestimate risk and thereby trade in riskier stocks.

This study examined interview accounts from thirty-one Taiwanese older adults about their inter- and intra-generational communication experiences, and perceptions of today's young and older people. Thematic analysis showed that Taiwanese older adults tended to initiate conversation topics accommodative to young people's lives such as their job and marriage, whereas conversation topics with their old-age peers centered on adjustment into senior years (e.g., health, exercise) and their children's achievement. Analysis also revealed some of the Taiwanese older adults' major perceptions of young people (e.g., less respectful towards elders) and their peers (e.g., losing status in the family). The discursive strategies used in constructing such perceptions (e.g., discourse on self exception, denial of self inclusion) demonstrated the ways in which they negotiated and managed their age identity in inter- and intra-generational communication. Results are discussed in light of Social Identity Theory, Communication Accommodation Theory, age identity, filial piety, and cultural change.

Drawing from intergroup contact theory and social identity theory, this study explored the indirect effects of out-group partisan media exposure (Fox News for Democrats; MSNBC and CNN for Republicans), and out-group interpersonal political discussions with members of the opposing political party on intergroup bias and intergroup competition through party identity as a mediator. We also accounted for the effects of in-group partisan media exposure (Fox News for Republicans; MSNBC and CNN for Democrats) and interpersonal political discussion with members of one's own party. The results suggested that interpersonal political discussion with "the other side" (out-group interpersonal discussion) and exposure to in-group media increased prejudicial attitudes and competitive intergroup behaviors, not only directly but also through enhanced party identity.

Two studies compared college students' interpersonal interaction online, face-to-face, and on the telephone. A communication diary assessed the relative amount of social interactions college students conducted online compared to face-to-face conversation and telephone calls. Results indicated that while the internet was integrated into college students' social lives, face-to-face communication remained the dominant mode of interaction. Participants reported using the internet as often as the telephone. A survey compared reported use of the internet within local and long distance social circles to the use of other media within those circles, and examined participants' most recent significant social interactions conducted across media in terms of purposes, contexts, and quality. Internet interaction was perceived as high in quality, but slightly lower than other media. Results were compared to previous conceptualizations of the roles of internet in one's social life.

This study examines the relationship between relational quality and media use in relationships. In addition, the impacts of other potentially important variables such as the sex and relationship type of the participants and their partners are explored. College student participants focused on interaction experiences with an acquaintance, friend, romantic partner or family member. The results indicated that participant sex and partner sex did not affect reported media use, whereas relationship type had significant effects on the extent to which face-to-face and telephone communication were used. Relationships with acquaintances had the lowest relational quality and romantic relationships, while closer, were less satisfying than either family or friendship relationships. Same-sex relationships were perceived as more satisfying than cross-sex relationships. Finally, media use did not predict relational closeness or satisfaction.
