I wonder about causation and correlation here. Presumably children whose parents can afford to pay for an extra year of childcare before sending them off to school can provide environments that also tend to produce self-regulation. One could also imagine that if waiting a year is somehow the non-standard choice, that having parents invested enough to take that option would give similar effects.

Further, the study explicitly claims causal relationships, rather than merely correlative. I'm guessing as a result of the kind of fancy-pants regression analysis they used.
