人們接吻時閉上眼睛真正的原因是大腦不能同時處理兩件以上事情。

When people pucker up the brain finds it difficult to process the sensation if cognitive power is also being used to analyse what we see, said psychologists from Royal Holloway, University of London.

人們嘟起嘴時,如果也一并用到認知力,則大腦很難處理感覺知覺,倫敦大學皇家霍洛威學院的心理學家如是說。

Tactile awareness depends on the level of perceptual load in a concurrent visual task. The cognitive psychologists reached their conclusion without studying people actually kissing. Instead people were asked do visual tests while their response to something touching their hands was measured.

觸覺覺知取決于同一時間發生的認知量水平。認知心理學家 得出此結論 并沒有真正去研究實際接吻的人。而是給人們一邊做視覺測試,一邊測量有實物接觸他們手部時他們的反應。

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.

專業人員發現視覺要凌駕于觸覺覺知,也就是說,要是人們所看到的事物很難加工處理,則很難繼續親吻。

If people are focusing strongly on a visual task, this will reduce the awareness of stimuli in other senses.

人們注意力高度集中在視覺任務上,那么對由其它感官帶來的刺激的敏感度就會降低。

The findings could also explain why people often shut their eyes whilst reading braille or when dancing.Shutting out the visual input leaves more mental resources to focus on other aspects of our experience.

研究發現同樣解釋了為何人們讀布萊葉盲文或者跳舞的時候常常會閉起眼睛。閉上眼睛沒有視覺信息輸入時,人們就有更多大腦資源來集中關注其它方面的體驗。
