Sex Linkage of Intelligence: The X-FactorBloomsbury Academic, 30 նոյ, 1997 թ. - 208 էջ The author presents a theory that major genes controlling the growth of human intelligence, both left- and right-brain attributes, are on the X-chromosome. The more significant of the implications of such X-linkage include:^L^L ^DBL Males tend to be more variable in intelligence. It is well known that males are far more likely to have intellectual deficits, including mental subnormality, learning disorders, and behavior problems. This book also presents evidence that males are more likely to be exceptionally high in cognitive abilities (other than memory), and in such areas as advanced mathematics, spatial perception, and creative music.^L ^L ^DBL Partial or total reversions to the aboriginal level of intelligence can account for virtually all cases of non-specific mental subnormality. These conditions are now identified by such terms as Renpenning syndrome, Martin-Bell syndrome, Fragile-X syndrome, and cultural-familial mental retardation. Because of the probability of offsetting genes, females are less likely to be severely affected by these conditions. |
