It’s time to go again to the A Moment of Science mailbag. A listener writes:
Dear A Moment of Science,
I’ve heard that owning a dog or cat can be a good way to deal with stress and ward off depression. So I was wondering–is it interacting with actual pets that’s beneficial, or would just looking at pictures of cats and dogs work to curb stress?
Interesting Question
Actually owning a pet is different from merely looking at pictures of cute puppies and kittens, certainly. Stress relief has a lot to do with the companionship that real pets provide.
Watching Videos
But one study showed that watching videos of animals can help reduce stress. And according to the study by researchers in Japan, looking at pictures of cute animals does appear to help us focus and concentrate. The researchers divided around 130 students into two groups and assigned each a task.
One group played an Operation like game that involved removing small objects from a hole without touching the sides. A second group was tasked with finding a number in a random sequence.
The Study
Within each group, participants were shown pictures either of puppies and kittens or of grown cats and dogs. A subset of participants in one of the groups was also shown pictures of appealing foods. The participants that saw the puppies and kittens consistently performed better than the others.
As for why viewing these cute images resulted in improved performance, the study doesn’t say. It seems reasonable to speculate, though, that feelings of happiness or warmth elicited by cute pictures helps relieve stress, thereby enabling the brain to focus and concentrate with greater power.
可愛的威力
又到閱讀《科學一刻》欄目來信的時間了。其中一個聽眾來信說:
親愛的《科學一刻》欄目組,
我聽說養(yǎng)狗或養(yǎng)貓是對待壓力和預防抑郁的好方法。所以我一直想知道,有益的是與真實的寵物互動嗎?或是只是看看貓貓狗狗的圖片就可以減少壓力呢?
很有意思的一個問題
實際上,擁有寵物當然有別于只是看看可愛小狗或貓咪的圖片。減壓與真實寵物給我們的陪伴有很大關聯(lián)。
觀看視頻
但是,一項研究顯示觀看動物視頻可以幫助人們減壓。而且根據(jù)日本學者的這項研究,看可愛動物的圖片似乎可以幫助我們集中精神。研究者們將130名左右的學生分成兩組,每組分配一項任務。
其中一組進行一種操作類的游戲,在不接觸孔洞側面的條件下將小物件從洞中移出。另一組則是要求在隨機序列中找到一個數(shù)字。
這項研究
在每一組里,研究者給參與者展示小狗小貓或是成年貓狗的照片。而在其中一個實驗組里的一小組參與者面前展示的是誘人食物的圖片。結果是,看到小狗小貓圖片的參與者們一致表現(xiàn)得優(yōu)于其他人。
至于為何觀看這些可愛的圖像能夠得到更好的表現(xiàn),這項研究并沒有給出原因。盡管如此,我們可以合理地猜測,由可愛的圖片所激發(fā)的開心和溫暖的感覺有助于舒緩壓力,由此使得大腦以更高的效率集中精神。
