Experimental Design

Experimental Design
We either pair a subject with anther subject, or pair a subject with a computer which randomly pick a strategy in Prisoner's dilemma. Before selecting an action, the subject can communicate with the other subject or receive ChatGPT generated message. We want to investigate whether subjects can tell whether they are interacting with human or robot, and whether they are more likely to cooperate in certain situations.
