Parents, does your 18-month-old seem wise beyond her years? Science says you’re not fooling yourself.
Very small children can reason abstractly, researchers say, and are able to infer the relationships between objects that elude older children who get caught up on the concreteness of things.
In experiments at the University of California, Berkeley, children as young as 18 months were able to figure out the relationship between colored blocks.
The child would watch a researcher put two blocks on top of a box. If the blocks were identical, the box would play music. The majority of children were able to figure out the pattern after they were shown it just three times. They would then help the researcher pick the correct block.
The toddlers did much better at this task than do chimpanzees and other primates. The non-human primates have to practice doing the task themselves thousands of times to figure it out. And even then, it’s only with lots of treats thrown in.
That’s not such a big surprise. What really got the researchers’ attention is that the diaper set did better at this sort of abstract thinking than children who were just a few years older.
“Older kids tend to be really bad at analogies,” says Caren Walker, a graduate student at in cognitive development who led the study. It was published online in the journal Psychological Science. She says that older children tend to focus on the objects rather than the relationships between them. “Learning may actually harm these kids’ abilities to do abstract reasoning.”
Walker is working in the lab of Alison Gopnik, a developmental psychologist who has made a career out of devising experiments that reveal the inner thoughts of children still too young to talk. Her take is that babies are smart, and in many ways smarter than adults.
