Declining intelligence in old age linked to visual processing (Science Daily):
“Researchers have uncovered one of the basic processes that may help to explain why some people’s thinking skills decline in old age… Read the rest of this entry »
Learning second language ‘slows brain ageing’ (BBC):
“Learning a second language can have a positive effect on the brain, even if it is taken up in adulthood, a University of Edinburgh study suggests…Using data from intelligence tests on 262 Edinburgh-born individuals at the age of 11, the study looked at how their cognitive abilities had changed when they were tested again in their seventies Read the rest of this entry »

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 »
