By age 2, most kids know how to play pretend. They turn their bedrooms into faraway castles and hold make-believe tea parties.<\/p>\n
The ability to make something out of nothing may seem uniquely human \u2014 a bedrock of creativity that’s led to new kinds of art, music and more.<\/p>\n
Now, for the first time, an experiment hints that an ape in captivity can have an imagination.<\/p>\n
“What\u2019s really exciting about this work is that it suggests that the roots of this capacity for imagination are not unique to our species,” said study co-author Christopher Krupenye with Johns Hopkins University.<\/p>\n
Enter Kanzi, a bonobo who was raised in a lab and became a whiz at communicating with humans using graphic symbols. He combined different symbols to make them mean new things and learned how to create simple stone tools.<\/p>\n
Scientists wondered whether Kanzi had the capacity to play pretend \u2014 that is, act like something is real while knowing it’s not. They’d heard reports of female chimpanzees in the wild holding sticks as though they were babies and chimps in captivity dragging imaginary blocks on the ground after playing with real ones.<\/p>\n
But imagination is abstract, so it’s hard to know what’s going on in the apes’ heads. They could just be imitating researchers or mistaking imaginary objects for the real thing.<\/p>\n
Researchers adapted the playbook for studying young children to stage a juice party for Kanzi. They poured imaginary juice from a pitcher into two cups, then pretended to empty just one. They asked Kanzi which cup he wanted and he pointed to the cup still containing pretend juice 68% of the time.<\/p>\n
To make sure Kanzi wasn\u2019t confusing real with fake, they also ran a test with actual juice. Kanzi chose the real juice over the pretend almost 80% of the time, “which suggests that he really can tell the difference between real juice and imaginary juice”, said Amalia Bastos, a study co-author from the University of St. Andrews in Scotland.<\/p>\n
A third experiment placing fake grapes into two jars had similar positive results.<\/p>\n
But not all scientists are convinced that Kanzi is playing pretend like humans do. There’s a difference between envisioning juice being poured into a cup and maintaining the pretence that it’s real, said Duke University comparative psychologist Michael Tomasello.<\/p>\n
“To be convinced of that I would need to see Kanzi actually pretend to pour water into a container himself,” Tomasello wrote in an email. He had no role in the study, which was published Thursday in the journal Science.<\/p>\n
Kanzi grew up among humans, so it’s hard to say whether his abilities extend to all apes or are because of his special upbringing. He died last year at the age of 44.<\/p>\n
Many great ape species in the wild are critically endangered and it’ll take more research to understand what their minds are capable of.<\/p>\n
“Kanzi opened this path for a lot of future studies,” Bastos said.<\/p>\n","protected":false},"excerpt":{"rendered":"By age 2, most kids know how to play pretend.
