New information on memory and how technology affects the brain results in new educational approaches, and this surveys the latest findings, revises sections on hemispheric specialization
processes, and expands resources to link with this new research.
The switch to bipedalism and new habitat necessitated the banding of hominids into cooperative groups and increased selective pressure on learning and imitation, leading to changes in the hormonal balance of the sympathoadrenal system, increased period of post-natal development, and growing hemispheric specialization
Tsur does not base his analysis of individual differences on hemispheric specialization
The brains of children with developmental language impairment also don't appear to develop the normal asymmetry between the hemispheres, which suggests that normal hemispheric specialization
of functions including language doesn't occur.
She has also contributed greatly to the study of hemispheric specialization
, the effects of early brain damage on cerebral organization at maturity, and the cognitive functions of the frontal lobes.
Laboratory and clinical studies of the left hemisphere's role in language focus on right-handers because left-handers display less predictable hemispheric specializations
for a variety of abilities.
Those without the genetic predisposition randomly divide into right-and left-handers, in her view; hemispheric specializations
are also randomly distributed in these people.
