Common wisdom asserts that your IQ is fixed. Of course, the various “multiple intelligences” change with personal life experiences and growth, but we usually consider the standard IQ score to be inherent and unchangeable. But even the standard IQ measure changes during different life stages. Clearly, the IQ of young children changes as they mature. Several studies even show that working-memory training can raise the IQ of elementary-school children. More than one analyst claims that a rigorous PhD program can raise IQ in adults. Most obvious is the decline of IQ in those elderly who do not age well because of disease. A neglected segment along the age spectrum is the teenage years. Now, evidence indicates that this age group experiences IQ changes ranging from a decline to an increase. A study of this issue shows that both verbal and non-verbal IQ scores in teenagers relate closely to the developmental changes that occur in brain structure during the teenage years. Longitudinal brain-i...

In an earlier post, I reviewed research showing that seniors compensate for any loss of memory ability by having developed learning and memory schemas over the years. Such schemas are ingrained strategies and ways of efficient learning that improve with experience and age. Now I have come across recent research that shows another age-developed skill: improved decision-making ability. Teenagers are notorious for poor decision-making. Of course that is inevitable, given that their brains are still developing and they have had relatively little life experience to show them what works and what doesn’t. Unfortunately, what doesn’t work often has more emotional appeal, and most of us at any age are more susceptible to our emotions than to cold, hard logic. Seniors also are prone to poor decision-making if senility has set it. Unscrupulous people take advantage of such seniors because a brain that is deteriorating has a hard time making wise decisions. In between teenage and senility is when ...
