What can we learn from the eight studies?

参考解析：

推理判断题。根据第三段中的第一句“Prior research has shown there are cultural stereotypes attached to names, including how someone should look”可知，先前的研究表明，名字上有文化上的刻板印象，包括一个人的长相；再根据最后一段中的第一句“To find out if face shape was linked to name, researchers conducted eight studies to see whether it was possible for strangers to correctly identify the names of people simply by looking at their faces. In every experiment, the participants were significantly better (up to 40 percent accurate) at matching the name to the face than random chance”可知，为了弄清楚脸型是否和名字有关联，研究人员开展了8项研究，来看陌生人能否只靠看脸就能准确把脸和名字对上号。在每个实验中，即便是在种族、年龄和其他社会经济变量可控制的情况下，参与者的配对准确率（40%）比随机配对的准确率（20- 25%）明显更高。可以推断出8项研究的结果和先前的研究结果一致，都表明外貌和名字有关联。故选D。
