Three-Year-Olds Know Better

A study finds that three-year-old children know a lot more than we might give them credit for. Christie Nicholson reports

Next time a three-year-old tells you what to do you might want to listen. Because three-year-olds can recognize when we adults are doing something counterproductive and are keen to help us find a better way. That’s according to new research in the journal Developmental Psychology. [Alia Martin and Kristina R. Olson, When Kids Know Better: Paternalistic Helping in 3-Year-Old Children]

Scientists had 58 three-year-olds examine several functional and nonfunctional objects. Like a real phone and a toy phone, or a working marker and a dried-up marker.

Then the researcher would say something like, “I need to make a phone call, can you get me the phone.” Sometimes they’d point to the real phone and other times point to the toy phone. The children would consistently bring over the functional item, regardless of whether the researcher pointed to it or asked specifically for it. In contrast, when they were told the item would just be thrown out, they’d bring either the nonfunctional or functional object. And in the case when any object would do, such as something that could act as a paperweight, the children brought either the fake one or the real one.

Ultimately the children focused on the end goal and deliberately choose the best item, as opposed to what was instructed of them. A good reminder for us adults.

It’s Time to Stand Up for Science

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.

I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.

If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.

In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.

There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.

Thank you,
