I would hope the actual study would make these distinctions explicit clear.
You can find it here, in the May/June 2012 edition of Child Development, volume 83, Number 3, Pages 779-793. 48-hour rent-to-read costs only $6.
"The coexistence of natural and supernatural explanations across cultures and development."
I'm backing up a claim that I didn't make to start with but was challenged to show evidence for. The very title of the study already indicates multiple cultures and multiple developmental stages. Mind to show me how do you back your claim of the opposite now?
