Another example:

Children who were "raised in the wild" or locked in a room by themselves have shown to be incapable of learning full human language.

The working theory is that our brains can only learn certain skills at certain times of brain development/ages.

We should also consider the effects of trauma on those brains. If you’ve ever spent time around people with extreme trauma they are very much in their own heads and can’t focus outside themselves long enough to focus enough to learn anything. It definitely impacts intellectual capacity. Humans are social animals and anyone raised without proper socializing and intimacy and nurturing will inevitably end up traumatized.
