为了弄清楚这种情况是否也适用于非生物，加州大学圣地亚哥分校的拉蕾·奎因和她的同事们测试了老鼠能否检测到机器老鼠发出的社交信号。
To find out if this extends to non-living beings, Laleh Quinn at the University of California, San Diego, and her colleagues tested whether rats can detect social signals from robotic rats.
奎因称，这表明老鼠将社交机器鼠看作了真正的社交生物。
This suggests that the rats perceived the social robot as a genuine social being, says Quinn.
在实验中，社交机器鼠跟随生物鼠四处走动，与它们玩同样的玩具，还会打开笼门让被困的老鼠逃走。

Across 18 trials each, the living rats were 52 percent more likely on average to set the social robot free than the asocial one.
她说，这可能会让老鼠更好地记住它们早些时候释放了机器人，并希望机器人在它们被困时回报这种恩惠。
This could lead to the rats better remembering having freed it earlier, and wanting the robot to return the favour when they get trapped, she says.
