奥本海默博士招募了28名年龄在18到40岁的志愿者,要求他们从书面文本的描述中学习关于三种外星生物的知识,其中每种生物又包含了七种特征。
This task was meant to be similar to learning about animal species in a biology lesson. It used aliens in place of actual species to be certain that the participants could not draw on priorknowledge.
这项任务旨在模拟生物课上学习动物种类的过程,它之所以用外星生物代替实际物种,是为了确保测试者不会凭借其原有的知识进行记忆。
Half of the volunteers were presented with the information in difficult-to-read fonts .
半数志愿者读的信息是难看的字体。
The other half saw it in 16-point Arial pure-black font, which tests have shown is one of the easiest to read.
另外半数读的则是16磅大小、Arial纯黑字体。
Participants were given 90 seconds to memorise the information in the lists. They were then distracted with unrelated tasks for a quarter of an hour or so, before being asked questions about the aliens, such as What is the diet of the Pangerish?
所有测试者有90秒时间记住清单上的信息,然后进行大约15分钟不相关的测试以分散他们的注意力,最后才提问他们关于外星生物的问题,例如潘格里氏主要吃什么?
