Training Working Memory: Why and how Make your working memory work for you. William R. Klemm Ph.D. https://www.psychologytoday.com/us/blog/memory-medic/201203/training-working-memory-why-and-how
Klemm makes the claim IQ is not fixed. He claims IQ improves dramatically in the early school years in all children. Moreover, a recent study shows that both verbal and non-verbal IQ can change (for better or worse) in teenagers. The recent study is cited in the above psychology today web link.
Is it a fact or a neuromyth to claim IQ is not fixed for adults? Processing speeds slow down as we get older, and working memory steadily deteriorates/declines as we get older, too. Are we doomed to get slower and have poorer working memories as we get much older (50, 60s, 70s, 80s)?
Or can we maintain our intelligence, working memory, and processing speeds for a longer period of time if we do physical exercise, keep physically fit, and live healthy lives?
