如果听者知道这是指甲刮黑板的声音的话,他们给这个声响难听程度的评级就会比被告知此声音来源于音乐作品中的高。
If they thought a sound came from a musical composition, they rated it as less unpleasant than if they knew it actually was fingernails on a chalkboard.认为声音是来自于乐曲的人会比知道声音是指甲划过黑板的人觉得这个声音没有那么令人不愉快。
But their skin conductivity changed consistently even when they thought the chalkboard sound was from music and rated it as less unpleasant.但是皮肤的导电性的变化是一致的,即使当他们以为黑板的声音是来自于乐曲,而且觉得它们也没有那么不悦耳。
