Document Summary

Sex differences in brain development: adults": females have proportionally more grey matter (neurons) while males have proportionally more white matter (myelated axons, female brains more lateralized (cid:224) grey matter more evenly distributed between the 2 brain hemispheres, solve problems differently: females use language related brain areas, males use visuospatial related brain area, male brain development takes longer than female brain development (cid:224) male brains more susceptible to environmental influence (cid:224) also more susceptible to poor environments (poor health and nutrition) Memory is involved in making this error (time waited between movement of object and allowing child to search for it (cid:224) child forgets that they saw the object move: slow frontal lobe maturation = inability to inhibit behavioural response (child was used to reaching into location a, so before he can learn reaching into location b, he must reach into location a again)
