Based on the concept of elaboration likelihood continuum (Petty & Cacioppo, 1986), this study constructs a best-fitting model that explains the structures of written arguments made by individuals in the context of text-based computer-mediated communication on a controversial issue. More specifically, this study explores how motivational and ability factors affect the structures of written arguments. Data were collected from Japanese college students (N=200) who participated in an online survey. As a result of testing two competing models—the simple main effects model and the intertwined model—the latter has demonstrated reasonable fit to the data. The results have been discussed and implications offered.
