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...

Want to become an expert? It doesn’t matter what the subject is, the principle for developing expertise is the same. My many years of personal experience and observing students convinces me of a learning axiom: the more you know, the more you can know. A recent research report helps to explain what the brain is doing as it acquires expertise. By observing which brain areas are active at the same time, one can conclude that such areas are probably functionally connected even though they are located at different locations within the brain’s network of circuits. In recently reported experiments, researchers used MRI scans of subjects as they rested after mastering a set of initial associations of pairs of faces and objects and as they learned new pairs. Scans were collected during rest immediately after subjects had memorized a series of face/object pairs, and during learning of new face/object pairs or pairs that did not overlap the original paired set. The data indicated that spontaneo...

Joe: My doctor told me to give up drinking, smoking, and fatty foods. Sam: What will you do? Joe: I think I’ll give up my doctor. I try not to get too excited about memory benefits of supplements, because too often the claims are not substantiated by studies that are well controlled and peer reviewed. I now think resveratrol may be one of the few supplements that benefits brain function. When I wrote my first blog on research on resveratrol benefits for brain function and memory, there were over 2,000 scientific papers. [1] Don't worry; I am only going to tell you about a few studies. Resveratrol is an active ingredient in red wine. This compound has been credited for explaining why red-wine drinkers in France, who drink more wine than most people, are healthier than would be predicted by their lifestyle of little exercise and eating lots of cheese. The problem is most studies suggest you would have to drink a 100 or more glasses of red wine a day to get much resveratrol effect (a...
