We continue our ten-part series exploring the brain with our favourite Neuropsychologist, Dr. Hannah Korrel. In part seven, we talk about IQ (what is it?) and other types of intelligence, the potential dangers of 'rating' people's intelligence, Maslow's Hierarchy of Needs, strategies for improving cognitive performance (brain function), emotional and social intelligence, my ever-fluctuating IQ and cognitive skills and lots more. Enjoy.
