Effective Computer-mediated Communication Using Hypertext: Introducing Expanding Hypertext--Are They Adventurous?
Unformatted Document Text:  Effective Computer-mediated Communication Using Hypertext 17 In condition 2, each article was presented in an expanding-hypertext format (Expanding Text). The expanding-hypertext consisted of links that allowed the reader to have more detailed information without losing the linear flow of information. This was achieved by links from highlighted, underlined key terms in the text. These links expanded or added more detailed information as the participant clicked on links. As in condition 1, the scroll bar on the right hand side allowed referring back to the previous information. After the participants finished reading each article, they clicked on the button "Finished" that automatically lead them to a set of questions measuring the dependent variables. In condition 3, each article was presented in a paged-hypertext format. The texts were presented with each excerpt on its own screen. The participant was able to navigate between excerpts by clicking on highlighted, underlined terms, serving as links (Paged Text). No structure was used between links.

Effective Computer-mediated Communication Using Hypertext

In condition 2, each article was presented in an expanding-hypertext format
(Expanding Text). The expanding-hypertext consisted of links that allowed the reader to have
more detailed information without losing the linear flow of information. This was achieved
by links from highlighted, underlined key terms in the text. These links expanded or added
more detailed information as the participant clicked on links. As in condition 1, the scroll bar
on the right hand side allowed referring back to the previous information. After the
participants finished reading each article, they clicked on the button "Finished" that
automatically lead them to a set of questions measuring the dependent variables.
In condition 3, each article was presented in a paged-hypertext format. The texts were
presented with each excerpt on its own screen. The participant was able to navigate between
excerpts by clicking on highlighted, underlined terms, serving as links (Paged Text). No
structure was used between links. Instead, wherever a term existed in the article for which an
elaborating excerpt existed, a link was presented. This created a web-like, user navigated
architecture of links where looping was possible. In this condition, a "Back" button was
available for the reader to return to previous screens, as would be found in a web-browser or
Windows Help file. After the participants finished reading each article, they clicked on the
button "Finished" that automatically lead participants to a set of questions about the
dependent variables.
Two hundred one undergraduate students were tested. Of the 201 participants, ninety-
four percent of the participants were between 19 and 23 years old.
Creating Indices
To create indices, a principal axis factor analysis with oblimin rotation was conducted
with related items to see factor loading. After a reliability test, a summed-index of factor
scores was created for each variable.
