Babies are smarter than we thought

In a great study from France some 150 5 month old infants were shown to be able to associate an abstract 3 syllable pattern with an image and react when the pattern wasn’t consonant with images they’d been shown many times before [ Proc. Natl. Acad. Sci. vol. 116 pp.

Well, the kids weren’t geniuses and talking.  So how could the researchers make such a statement?  The babies were sitting in their parents laps with a high density (120 electrode) EEG cap on their heads.  They were exposed to monosyllable triplets in various patterns AAB, ABA, ABB, BBA etc. Following  each triplet presentation a picture of a fish or a lion was shown.

For example,  for most of the time they experienced AAB lion AAB lion AAB lion —but occasionally AAB fish was thrown in.  The EEG was quite different with the fish.

Even better, they exposed the child to the picture (lion) first followed by the trisyllable.  If the trisyllable was AAB there was no reaction, but it if was ABA there was a reaction implying that the babies had linked the picture and the sound pattern.

This is excellent evidence for the ability of 5 month old infants to associate an abstract (sound) pattern with an unrelated visual stimulus.

They did many more experiments but you get the idea.

You’d better. The infants did.

It would be fascinating to repeat the experiment with chimpanzees.
