Research problem: Deciding whether to accept or reject contract clauses in software purchasing contracts is a complex communication-related task, which is likely faced daily by a multitude of software purchasing professionals in a variety of organizations. Research question: What are the effects of viewing contract clauses as video clips, compared to viewing clauses as text only, in terms of cognitive effort, communication ambiguity, and correctness in the acceptance or rejection of clauses in software purchasing contracts? Literature review: The literature on the Media Richness and Media Naturalness theories suggest that viewing contract clauses as video clips should reduce cognitive effort and communication ambiguity. However, while Media Richness theory suggests that correctness in the acceptance or rejection of clauses in software purchasing contracts should increase with the use of video clips, Media Naturalness theory suggests a neutral overall effect. Methodology: An experiment was conducted in which student participants were asked to either accept or reject 20 clauses from a software contract, placing themselves in the position of buyers. Of the 20 clauses, 6 were intentionally deceitful and potentially harmful to the buyer. Approximately half of the participants reviewed the contract clauses as web-based text, and the remaining as web-based video clips. Results and conclusions: Viewing contract clauses as video clips was associated with significantly less cognitive effort and less communication ambiguity than viewing the clauses as text only. Counterintuitively, increases in perceived cognitive effort and communication ambiguity were associated with more successful identification and rejection of deceitful contract clauses. The combination of these competing effects led to an overall neutral effect of the medium on the correctness in the acceptance or rejection of clauses. These findings are consistent with expectations based on Media Naturalness theory, particularly its compensatory adaptation proposition, and inconsistent with expectations based on Media Richness theory.

It is evolutionarily adaptive for humans to have enhanced memories of events surrounding surprise situations, because in our ancestral past surprise situations were often associated with survival threats. Vividly remembering memories immediately before and after a snake attack, for example, allowed our hominid ancestors to be better prepared to avoid and deal with future attacks, which in turn enhanced their chances of survival. This study shows that such enhanced memorization capacity likely endowed on us by evolution can be exploited for knowledge communication through computer interfaces. A knowledge communication experiment was conducted in which subjects were asked to review Web-based learning modules about International Commercial Terms (Incoterms), and then take a test on what they had learned. Data from six learning modules in two experimental conditions were contrasted. In the treatment condition, a Web-based screen with a snake picture in attack position, displayed together with a hissing background noise, was used to create a simulated threat that surprised the subjects. In the control condition the simulated threat was absent. As expected, based on the evolutionary psychological view that surprise can enhance learning, the subjects in the treatment condition (i.e., with the snake screen) did approximately 28% better than those in the control condition (i.e., without the snake screen) at learning about Incoterms. This improvement occurred only for the two Web-based modules immediately before and after the snake screen. Those two modules comprise what is referred to in this study as the surprise zone. There were no significant differences in learning performance between the two experimental conditions for modules outside the surprise zone.

It starts with a discussion of the motivation for the Special Section, followed by several sections written by the Guest Editor (Ned Kock) and the Guest Associate Editors (Donald Hantula, Stephen Hayne, Gad Saad, Peter Todd, and Richard Watson). In those sections, the Guest Editor and Associate Editors put forth several provocative ideas that hopefully will provide a roadmap for future inquiry in areas related to the main topic of the Special Section. Toward its end, this article provides a discussion on how biological theories of electronic communication can bridge the current gap between technological and social theories. The article concludes with an answer to an intriguing question: Are we as a species currently evolving to become better at using electronic communication technologies? </para>

Hofstede's cultural dimensions model has been widely used as a basic explanatory and predictive model in a variety of business studies, including studies addressing information management and electronic communication issues. This study aimed at assessing Hofstede's model by looking into a key issue for information management and electronic communication-information overload. The study compared information overload-related data from the US and New Zealand. The sample involved 108 MBA students who held professional or management positions. Data analyses employed comparisons of means and partial least squares (PLS)-based structural equation modeling techniques. Information overload perceptions in the two countries appear to differ significantly. This finding seems to be inconsistent with the relatively small differences in cultural dimension scores between the US and New Zealand, and with those two countries being placed in the same country cluster in Hofstede's model. The results call into question the adequacy of Hofstede's model as a basis to explain information management phenomena.
