Just a couple weeks ago I had a discussion with several psychologists and neurologists who seemed to share the opinion that “brain fitness” is a meaningless concept and pursuit. On the one hand, they thought, intelligence is a fixed trait and no intervention has shown so far to reliably increase it. On the other hand, nothing has been shown to prevent the pathology of Alzheimer’s Disease. According to this mindset…why bother?
Well, what if such mental framework was wrong or, worse, misleading? Read the rest of this entry »

When it comes to our understanding of human intelligence, for too long, there has been a mismatch between theory and practice. Theoretically, the two main threads running through definitions of intelligence have been (a) adaptation to the environment, and (b) the cognitive, affective, and volitional characteristics that enable that adaptation. Practically, IQ tests measure an important but limited slice of intellectual functioning in a very limited testing environment. Why such a disconnect?
Intelligence tests were born out of necessity. Read the rest of this entry »
Intelligence tests offer insight into ageing brain (BBC News):
“Sixty-six years ago today, more than 70,000 10 and 11-year-old children across Scotland took an intelligence test…now they have formed the foundation of a remarkable research project which is producing valuable insights into what lies behind cognitive decline — or ageing of the brain… Read the rest of this entry »
Teamwork Builds Big Brains (Science Now):
– “The average adult human’s brain weighs about 1.3 kilograms, has 100 billion or so neurons, and sucks up 20% of the oxygen we breathe. It’s much bigger than an animal our size needs. According to a new computer model, the brains of humans and related primates are so large because we evolved to be social creatures.“
– “The idea behind the so-called social intelligence hypothesis is that we need Read the rest of this entry »

NIH-funded study finds dyslexia not tied to IQ (NIH press release):
At left, brain areas active in typically developing readers engaged in a rhyming task. Shown at right is the brain area activated in poor readers involved in the same task.
- “Regardless of high or low overall scores on an IQ test, children with dyslexia show similar patterns of brain activity, according to researchers supported by the National Institutes of Health. The results call into question the discrepancy model — the practice of classifying a child as dyslexic on the basis of a lag between reading ability and overall IQ scores.”
- “In many school systems, the discrepancy model is the criterion for Read the rest of this entry »
