This article rather strangely assumes that a child's upbringing ends between the ages of 5 and 12. Regardless of whether you think religion is a wonderful or a terrible thing, surely the correct outcome measure would be generosity in adulthood. There is no reason to believe that this study is predictive of adult behavior, which is what the article implies. Interestingly, studies looking at 2 or 3 year-olds in bilingual households show that the child's development on either language is delayed compared to monolingual peers IIRC, but later comparisons at around age 6 show their use of language is at least as good, in both languages. The same phenomenon could at least conceivably be true in religious households.
