I think the articles talks about this: the child still wakes up in the middle of night but does not cry. Scientists are not sure what is happening, are they able to sooth themselves to sleep or are they still stressed out but are not crying. Because they know nobody will come for help if they cry.

Everyone wakes up at night.

If my son wakes up at night and needs some water, he'll cry. Diaper change, cry. I have a nursery can and I can see him wake up sometimes, look around, and go back to sleep on his own, because that is perfectly natural.

W/o sleep training he wanted to be patted back to sleep everytime he woke up. That took 15 to 30 minutes, 2 to 4 times a night.

After sleep training, he sleeps better, and gets more sleep, and still has all his needs taken care of.

And non-cranky parents who aren't bothering him every second he's awake.

The child is avoiding crying in the absence of its parents because doing so would cause predators to find him before his parents. Evolutionary instinct. The parents will (hopefully) return from hunting & gathering eventually, to pick the child up.

And when the parents regularly fail to return or never return - yeah, one way ticket to a psychological disorder.

Only with sleep training, the parents do return in the morning, so what's your point?

Of course a neglected child is likely to grow up with a psychological disorder. Neglected as in the parents (or at least some carer) not being there for days on end, or simply abandoning them. That's not sleep training though.
