A SUGGESTED CORRECTION OF THE HENDRICKSON PARADIGM - THE HEMISPHERICITY AND THE BRAINS CONSUMPTION OF ENERGY FACTORS

According to the Hendrickson paradigm of intelligence (Hendrickson & H endrickson, 1980, 1982) it is expected that the string and the amplitu de measures of averaged evoked potentials are positively correlated wi th IQ. However, attempts to replicate the Hendricksons' experiments sh ow that these correlations are sometimes significantly positive, somet imes significantly negative, and sometimes not significant It is sugge sted that these variable results may be explained by the paradigm of H aier et al. (1988, 1992) according to which intelligent brains consume less energy, by the difference in the consumption of energy by left-h emispheric and right-hemispheric brains, and by hemisphericity-related individual differences in the conducticity of the corpus callosum.
