The pattern of responses shown by Wilma corresponds to the tit-for-tat strategy, which involves initially cooperating and then responding with whatever the other person did in the previous round. Wilma cooperated in the first round (as did Chad), but then responded to Chad's defection in the second round with a defection of her own. In the third round, she again responded to Chad's defection with a defection, but then returned to cooperation in the fourth (after Chad had also cooperated). This is consistent with the tit-for-tat strategy and suggests that Wilma is attempting to strike a balance between cooperation and competition based on Chad's behavior.
