PSYC 3365 Lecture Notes - Lecture 10: Nerve Conduction Velocity, Haier, Frontal Lobe
Document Summary
Using problem solving in everyday life to meet environmental challenges. Intelligence: the ability to reason, to understand, and to profit from experience (textbook) Is it one ability or multiple abilities: neurobiology of intelligence. It was once thought that a larger brain = more intelligence: paul broca (1800s, francis galton (1888) a students had a 3. 3% larger head size than b students. A larger brain does not make people more intelligent. Ex: albert einstein had a very typical brain; not real differences except in certain areas. The ratio of brain size to body size in the most important. Cortical (cerebral cortex) thickness in some areas may relate to intelligence, especially the volume of gray matter in the frontal lobe. Increased intelligence is related to having more white matter and more gray matter: males 6. 5x more gray matter in intelligence areas, females 10x more white matter. Iq scores are also correlated with nerve conduction velocity.
