The second piece of evidence was that men should show even more signs of leadership emergence when the task is masculine in nature. Dovidio and colleagues' study is particularly supportive of this second necessary piece of evidence. First, men showed higher levels of verbal and nonverbal communication than women on a gender-neutral task. However, when the dyads worked on a masculine task (discussing changing oil in a car), the difference became ever greater. The study also provided support for the third piece of evidence (i.e. women should show slightly greater signs of leadership emergence when task is feminine in nature) because when the topic shifted to feminine in nature women actually exhibited greater power. Providing further evidence that status beliefs are central to these phenomena, several studies have shown that no differences appear when the task is performed in same sex groups.
