Document Summary
The brain changes: brain volume shrinks a little. Changes are in the gray matter (cell body, dendrites, glia: slight reduction in number of neurons. The brain is gradually changing: prefrontal cortex is finally mature, brain slows slightly . Neuron firing ore slowly: this is almost . Brain changes: brain changes are more extensive when there is. Viruses: less than 1% have significant loss. True or false: as people grow older, their intelligence declines significantly, false. What is intelligence: more than one thing, many different aspects to intelligence. What happens to cognition in adulthood: the old view-now rejected-was steady decline in cognitive abilities in adulthood, cross sectional research showed this (wrong) pattern, we"re measuring cohort effects which were getting in the way.
