TRANSCRIPT

Good afternoon. I am a researcher who studies play from a biological, evolutionary perspective. I’m interested in the reasons why play came about in the course of natural selection, I’m interested in the evolutionary function of play.

So I am going to start with animals. Young mammals of essentially all species play. In play, they develop fit bodies, they practice physical skills that are crucial to their survival, and they also practice social and emotional skills. By playing together, they learn to cooperate with one another, they learn to be in close vicinity with one another without losing their tempers — it’s very important for social animals to develop.

In risky play, they learn to take risks to experience fear without losing their heads — a lesson that can save their lives in the course of a real emergency.

Researchers have conducted laboratory experiments in which they had deprived young animals — usually this is done with rats, but sometimes with monkeys — of the opportunity to play as they’re growing up. And they’ve developed ways of doing this without depriving them of other social experiences; at least with rats, they develop ways of doing this. The result is that when these young animals develop, they are socially and emotionally crippled.

When you place one of these play-deprived animals in a somewhat novel, somewhat frightening environment, they overreact with fear: they freeze in the corner, they don’t adapt to — they don’t explore the environment as a normal animal would.

If you place one of these play-deprived animals with an unfamiliar peer, they alternately freeze in fear and lash out with inappropriate, ineffective aggression; they don’t learn to respond to the social signals of the other animal.

It is not surprising that those mammals that have the largest brains and that have the most to learn, are the ones that we find play the most.
