Document Summary
Lecture 9 - chapter 10 & 12 (mar28) Brain size (more intelligent = more neurons) Numbers of neurons goes down a intelligence goes up significantly. Note the role of development and plasticity and intelligence. Some evidence support more intelligent people have faster reaction times. No causal link between speed of information processing and intelligence (luciano et al. Being fast also means you also generate more mistakes. Speed = quantitative measure =/ needed for intelligent processing. *not just the speed of your hardware but how the software uses it. People with higher iq activate less of their cortex (neubauer et al. ) Making prediction is what brain efficient at (pattern, sequences) Connection between intelligence and plasticity - neural pruning (garlick 2002) What scope of prediction do you use? (short term vs. long term efficiency) As you add neurons between stimulus and response neurons.
