In the Community/Wall Street Game experiment, what was manipulated to observe differences in behavior?

The correct answer focuses on the manipulation of how the game was framed through its name, distinguishing between a community-oriented perspective and a competitive, individual-focused perspective. The research analyzed whether referring to the game as the "Community Game" or the "Wall Street Game" would lead participants to adopt different behaviors and approaches to decision-making.

The framing of the game influenced participants’ attitudes and actions significantly, with those playing the Community Game tending to cooperate more and those in the Wall Street Game opting for more competitive or selfish strategies. This manipulation highlights the importance of context and labeling in shaping social interaction and behavior.

Other aspects, such as the number of participants, the specific benefits to winners, or the types of rewards offered, were not the primary changes that affected player behavior in a way that aligned with the experiment's aims. Instead, the focus was on how the titles provided a psychological framework that affected decision-making, thus underlining the substantial role of social context in influencing human behavior.
