Document Summary

Differences in einstein: parietal lobes 15% bigger than average, frontal lobes had more grooves, 2 hemispheres had more connections. Reaction time (time it takes to respond to a stimulus) Perceptual speed (how fast the brain assesses something) Nerve conduction velocity (ncv): how fast neurons transmit electrical information. The dynamics of intelligence (study aging & intelligence, rest not included for first midterm, a must for final) Stereotype threat: perform less well than our abilities. Stereotype lift: positive stereotype activated, tend to perform better (asian women) Flynn effect: since the beginning of the 20th. Century, iq scores have been rising every decade (2-5 points) Ethnic differences: most likely due to environmental factors. Lower iq if poverty and discrimination is involved. Beliefs shape outcomes (remember: race is a biologically meaningless concept) Specific training in spatial abilities for women eliminates differences. Verbal: associated with size of frontal lobes, and amount of estrogen. Bigger differences in iq are within a group.
