Document Summary

Frontal lobe has many functions (executive functions, thinking, planning, etc) Cerebral cortex takes more than 20 years to mature. Synaptogenesis increases gradually (especially in the frontal lobes ~12 to 16 months) This slow development in our frontal lobe explains why preschoolers have problem controlling behaviors. Also explains how our ability to plan, think and inhibit our actions improves over the years. Corpus callosum (white matter tract that connects 2 hemispheres) Involve in transfer of information and integration of information; working memory. Specific functions become more localized to one hemisphere. Boys: greater lateralization of language in left hemisphere. Language is more evenly divided b/w 2 hemispheres. Or verbal abilities emerge earlier because girls receive greater encouragement for verbal skills than boys. Individual differences (sex differences, nation and global economic differences) Middle childhood (only time when girls on average are taller than boys)
