To find out if this extends to non-living beings, Loleh Quinn at the University of California, San Diego, and her colleagues tested whether rats can detect social signals from robotic rats.They housed eight adult rats with two types of robotic rat-one social and one asocial -for 5 our days.The robots rats were quite minimalist, resembling a chunkier version of a computer mouse with wheels-to move around and colorful markings.During the experiment, the social robot rat followed the living rats around, played with the same toys, and opened caged doors to let trapped rats escape. Meanwhile, the asocial robot simply moved forwards and backwards and side to side.Next, the researchers trapped the robots in cages and gave the rats the opportunity to release them by pressing a lever.Across 18 trials each, the living rats were 52 percent more likely on average to set the social robot free than the asocial one. This suggests that the rats perceived the social robot as a genuine social being. They may have bonded more with the social robot because it displayed behaviors like communal exploring and playing. This could lead to the rats better remembering having freed it earlier, and wanting the robot to return the favour when they get trapped, says Quinn.The readiness of the rats to befriend the social robot was surprising given its minimal design. The robot was the same size as a regular rat but resembled a simple plastic box on wheels. "We'd。
