A group of researchers from Cologne University has concluded that chewing makes us immune to film advertising.
For their experiment, the researchers invited a group of 96 people to a cinema to watch a movie preceded by a series of adverts. Half of the participants were given free popcorn throughout the session, the other half only received a small sugar cube which immediately dissolved in their mouths.
A test at the end of the screening showed that the adverts had left no effect on those viewers who had chewed popcorn, while the other participants showed positive psychological responses to the products they had encountered in the ads.
科隆大学的一个研究小组得出结论，咀嚼可让人对电影广告免疫。
在实验中，研究人员邀请96名实验对象去影院观看一部在开头播放一组广告的电影。在广告播放期间，其中一半人可以得到免费的爆米花，而另一半人只得到一小块入口即化的方糖。
放映结束后进行的测试显示，那些吃爆米花的观众对这组广告完全没印象，而其他那些观众却对广告中的产品产生了积极的心理反应。
