Being in a good mood decreases the brain's working memory, US researchers say.

美國研究人員稱，好心情可能會降低大腦的工作記憶(屬程序性記憶、短時記憶，是一種短暫時刻的知覺)能力。

“This explains why you might not be able to remember a phone number you get at a party when you are having a good time,” Elizabeth Martin, a doctoral student of psychology at the University of Missouri, says in a statement. “This research is the first to show that positive mood can negatively impact working memory storage capacity.”

“這就能解釋為什么明明在派對上玩得很開心，卻記不住從派對上得到的電話號碼，”密蘇里大學心理學博士伊麗莎白馬丁在一份報告中指出。“該研究首次說明，積極情緒有損于工作記憶容量。”

The researchers gauged study participants'mood before and after showing them a video clip - some saw a bit of a stand-up comedy routine, while others saw a video on how to install flooring.

研究人員在受試者觀看視頻片段前后對其情緒進行了測量。其中一部分受試者所看的是輕松喜劇節(jié)目，另一些人所看的視頻則關(guān)于如何鋪地板。

Those who viewed the comedy routine were in significantly better moods after viewing the video, while the mood of flooring group had not changed. Both groups were then given a memory test.

那些看了喜劇的受試者觀后情緒更佳，而“地板視頻”受試者觀前觀后情緒并無波動。兩組都接受了記憶測試。

The study, published in the journal Cognition and Emotion, found those who watched the comedy routine performed significantly worse on the task.

此項刊登于《認知與情感》雜志的研究發(fā)現(xiàn)，觀看了喜劇的受試者在記憶測試中表現(xiàn)明顯差于另一組受試者。
