Instead people were asked do visual tests while their response to something touching their hands was measured.

研究人员对受试者进行了视觉测试，同时用东西触碰他们的手，观察记录他们的反应。

The academics found that the visual field overrides tactile responses - meaning people would struggle to continue kissing if what they were looking at became more difficult to process.

研究人员发现，视觉反应凌驾于触觉反应之上，也就是说，如果大脑处理接吻时所见之物的处理难度加大，接吻就很难持续。

Dr Dalton told The Sunday Times: 'If we are focusing strongly on a visual task, this will reduce our awareness of stimuli in other senses.

道尔顿博士告诉《星期日泰晤士报》：“如果我们的注意力都集中在视觉任务处理上，对其他感知的感觉能力就会减弱。”

'It is important for designers to be aware of these effects, because auditory and tactile alerts are often used in situations of high visual demand, such as driving a car or flying an aircraft.'

“对实验设计人员来说，认识到这类影响非常重要，因为对视觉注意力要求较高的情景经常会用到听觉和触觉感知，比如驾驶汽车或飞机。”

The findings could also explain why people often shut their eyes whilst reading braille or when dancing.

这一发现也解释了为什么人们在阅读盲文或跳舞时通常都会闭着眼睛。
