To test the hypotheses, the experimental groups must have variance in the degree of cooperativeness of their initial discussion. We will manipulate this through assignment of subjects to groups. Prior to the study we will give subjects a pretest to assess their motivational orientation and assign them to groups based on cooperative or individualistic orientation. We use a 2 X 5 factorial design. A graphics-based simulation of a commons dilemma situation based on fisheries will be utilized as the experimental task.
Subjects play the game simultaneously, interacting in real-time over a series of fishing seasons.
Subjects may select different harvesting strategies and collective behavior is reflected in the level of fish stock available. FISH is a complex, realistic experimental stimulus that is well-suited for this study. The CMC system provides computer conferencing over the internet. It enables participants to engage in a discussion electronically. No structure beyond this will be imposed.
