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...

School is ending for the year, and students surely welcome the break. But they will do well to think on how they learn to learn so that next Fall they can be more successful with less effort. Interesting how that reminds me of my e-book for students, Better Grades, Less Effort. In my experience with students, both the college students I teach and the secondary students that teachers tell me about, the biggest weakness students have is that they either try to remember school material by rote memorization or have no strategy at all, relying on some kind of magical mental osmosis.  Even among students who rely on rote memory, they generally lack much of a strategy for memorizing, relying on varying degrees of casual “looking over” the instructional material until they think they can remember it. Experiments show that students routinely over-estimate how much they remember and under-estimate the value of further study. Moreover, many educators at all levels have disdain for memorizatio...

Working memory refers to the memory you can consciously hold in your mind at any one instant — such as a phone number you just looked up. Most people can only hold about four totally independent items in their working memory. Working memory relates to intelligence. The reason is that thinking involves streaming into the brain’s “thought engine” chunks of information held in working memory. The working memory streams in, much like a Web video streams into your computer. The more you can hold in working memory, the more information the brain has to think with — that is, the smarter it can be. IQ is not fixed. It 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. Educators have known for some time that it is possible to train ADHD children to have better working memories, and in the process improve their school performance. The idea that working memory capacity mi...
