A new Japanese study has found that cats match dogs in some memory tests.日本的一項新研究發現，貓在某些記憶力測試中與狗相匹配。

 The study used 49 cats and different bowls of food, and the result shows that cats can recall memories of positive experiences, such as eating a delicious snack.這項研究使用了 49 隻貓和不同碗的食物，結果表明貓可以回憶起積極經歷的記憶，例如吃美味的零食。

 The experiment was a test of episodic memory, or memory of past experiences that occur at a particular time and place.該實驗是對情景記憶的測試，即在特定時間和地點發生的過去經歷的記憶。

 In the experiment, cats were led to four bowls of food, and were permitted to eat from two of them.在實驗中，貓被帶到四碗食物中，並被允許吃其中的兩碗。

 After fifteen minutes, the bowls were replaced with empty ones, and the same cats returned to the room in search of food. 十五分鐘後，碗被換成了空碗，同樣的貓又回到房間尋找食物。

Here, researchers found that the cats spent more time exploring those bowls from which they had already eaten than others.在這裡，研究人員發現，這些貓比其他貓花更多的時間探索它們已經吃過的碗。

 That cats were able to remember “what” and “where” information about the food bowls suggests they have episodic memory.貓能夠記住有關食物碗的「內容」和「地點」訊息，這表明它們具有情景記憶。

 The researcher said that both cats and dogs may have episodic memory similar to that of humans and that cats are just as smart as dogs.研究人員表示，貓和狗可能都具有與人類相似的情景記憶，而且貓和狗一樣聰明。

 Still, it’s unclear whether cats can experience past memories as deeply as humans do. 儘管如此，目前還不清楚貓是否能像人類一樣深刻地體驗過去的記憶。

“It’s also hard to know if the cats actually remember the experience of going to that particular bowl, such as the colors and the sounds,” said the researcher.研究人員說：“也很難知道貓是否真的記得去那個特定碗的經歷，例如顏色和聲音。”

 The study’s results may have many practical uses. 研究的結果可能有許多實際用途。

A professor from Yale University said, “It opens the door to new studies examining how long cats’ memories can be, and whether they also remember richer experiences in their own life as humans do.”耶魯大學的一位教授表示：“這為新的研究打開了大門，研究貓的記憶能有多長，以及它們是否也能像人類一樣記住自己生活中更豐富的經歷。”
