Sato (1987) Gave Japanese Students Opportunities to Harvest Trees in a Simulated

Sato (1987) gave Japanese students opportunities to harvest trees in a simulated forest for money. When the students equally shared the costs of planting the forest, the result was that

A) most of the trees were left to grow too tall for harvesting because the students bickered about the criterion to be used in sharing profits.
B) most of the trees were harvested before they had grown to the most profitable size.
C) none of the trees were harvested because the collectivist students did not want to be the first to ask for his or her share.
D) students made maximum profit not only for themselves individually but for the group.
