So I would say - kind of. But at it's root, the mechanisms are based on having a social network of people touching, talking, playing etc... that does the training - though it might not look the same.
A perfect example I use all the time which is much later in development but relevant, is when a 1.5 year old will point at something and ask if it's a [thing]. The initial training was people segmenting (holding, moving different ways) classifying (calling it [thing], asking for [thing], telling the subject it is [thing]), which was then reinforced/weighted by asking if [thing] was indeed [thing].
So it doesn't look like explicit training, but it follows all the same steps.
