Document Summary
Most prominent finding is that a distributed neural network involving the frontal & parietal lobes is related to higher intelligence: parietal lobes responsible for cognitive control & connectivity to brain regions outside the network. Temporal & occipital lobes & cerebellum also linked to intelligence: both heredity and environment likely contribute to links between the brain and intelligence, including the connections between brain size and intelligence. Page 248 for review on this section (1) controversies and group comparisons. Highest possible degree of heritability is 1. 00 correlations individuals researchers use this concept to try to describe. Refers to a specific group (population) rather than the of . 70 and above suggest a strong genetic influence why people differ: limitations: Heritability index is only as good as the data that are entered into its analysis and the interpretations made from it. Data are virtually all from traditional iq tests, which some experts believe are not always the best indicators of intelligence.
