This is a striking statistic: "...children born in August in those states are 30 percent more likely to receive an ADHD diagnosis, compared with their slightly older peers enrolled in the same grade."
- rusabd 8y agoIt is similar to hockey paradox when NHL players are most likely to be born in December
- dudul 8y agoHow is it a "paradox"? It makes total sense that kids older and bigger will dominate most sports. It will re-enforce their self esteem and confidence and help them get even better. I don't dispute the phenomenon, I've never heard it called a "paradox".
- mathgeek 8y agoI think what was meant here is the Relative Age Effect: https://en.wikipedia.org/wiki/Relative_age_effect https://en.wikipedia.org/wiki/Relative_age_effect Many here probably recall if from Super Freakonomics.
- rusabd 8y agoAh, "effect", of course. This is what I meant
- SilasX 8y agoSufficiently unintuitive reality is indistinguishable from paradox.
- rusabd 8y agoWell, I made a mistake by saying that "NHL players most likely to be born in December" when in fact they most likely to be born in January. December is the horrible month to be born for a future NHL star (https://www.quanthockey.com/nhl/birth-month-totals/nhl-players-career-stats.html https://www.quanthockey.com/nhl/birth-month-totals/nhl-playe...). So it is not that obvious, isn't it? :)
- Oletros 8y agoIs there a cut for date for starting school? Here in Spain, everyone born in the same year goes to the same class, is it different in USA?
- dudul 8y agoAs per the article itself, many states implement the "1st of September cut date". A kid born in September has to wait an entire year to start school compared to one born on 08/31.
- throwaway123032 8y agoAnd in Switzerland, 1st August. Retardness.
- bigpicture 8y ago> Here in Spain, everyone born in the same year goes to the same class, is it different in USA? So Spain has a cut date of 1 Jan while the USA is 1 Sept. The overall effect is exactly the same: When a school term begins, some of the students will be nearly 1 year older than some of the others.
- WhompingWindows 8y agoIt's yet another piece of evidence that ADHD is a developmental disorder, it develops over time, and those who are younger have brains which are underdeveloped. Their ability to tamp down disruptive behaviors and use executive functioning to effectively manage planning is reduced compared to other children. So, in younger children, those who are borderline ADHD will appear to be more solidly ADHD, and those with moderate or severe ADHD will seem to have worse symptoms, as we're putting them in a classroom and comparing them with children whose brains have a higher EF capacity. It's also worthwhile to note that the gold standard diagnosis of ADHD involves observation of childrens' behavior in the classroom, where they will be compared to older, more neuro-developed classmates.
- jonhendry18 8y agoExcept sometimes it doesn't go away with age.
- x220 8y agoIt's almost as if we diagnose children with ADHD for acting how healthy young children naturally act.
- bayesian_horse 8y agoThe problem is that children with ADHD are acting somewhat how healthy - but much younger - children naturally act. There seems to be another component though. Adults with ADHD can be quite "mature" in most respects, while still having trouble related to the disorder. Hyperactivity and lack of impulse control are only part of the disorder, and not necessarily that pronounced.
- 24gttghh 8y agoI think it would make more sense to have an evidence-based determination for what grade a child should start in, rather than some arbitrary cut-off date like we have now.
