PSYC31H3 Chapter 8: Chapter 8 notes
Document Summary
Aging: verbal fluency tends to decline more with age than confrontation naming, perceptual integration and reasoning show age related declines, arithmetic problem solving changes little with age. But when reasoning is required, there is little decline with age: concept formation and abstraction decrease with age older = concrete thinking. Right handers: 90-95% of people, fewer males are right hand dominant than females throughout the lifespan. Left handers: majority of nondextral left handers are left cerebral language dominant, those who are not are typically bilater, not entirely right-dominant, left-handed family history leads to more likely atypical language representation. Neuroanatomic correlates of handedness: non-consistent right hand preference have more callosal substance than those with a consistent right hand preference holds only for men. Handedness and cognitive functions: familial left-handedness may play a role in cognitive functioning, right-handers perform better on visuospatial tasks. Determining cerebral lateralization: most brain injuries don"t come in neatly lateralized packages.
