Kinder mit ADHS geben an, im Vergleich zu Gleichaltrigen weniger Anstrengungen bei kognitiven Aufgaben zu unternehmen

Stuck in low gear. Accelerates quickly, falls off when sustained effort and focus are needed. 

Have you seen my keys?

I’d like to see a similar study done on younger kids, though I’ll admit it might be harder to find a large sample size as many kids don’t get diagnosed till 6 or 7 at the earliest. My question is though, is this behavior inherent, or learned over time? I’ve noticed with the ADHD kids I’ve worked with (and especially boys) is that they are often super competative but do NOT handle losing well. As a result, some seem to develop this tendency to deliberately “not try hard” ever so that if/when they lose/fail they can brush it off as “oh I just wasn’t trying.”
