Overweight-more than 85th
Obesity-higher than 95th
Why are rates of overweight/obesity rising in developed countries
Diets are becoming more like developed countries
Overweight
In children-BMI higher than 85th percentile for age
Obesity
In children higher than 95th percentile for age
Children who watched at lease ___ hours of tv a day gained ___ more body fat over course of study than those who watched less than 1 1/2 hours
Three hours

acquiring an understanding of concrete operations depends on..
exposure to similar task and materials
ex-westerner performed better on standard test of concrete operations whereas mayan children were better at concrete operations task that involved materials used in weaving

myelination in brain especially in corpus callosum
selective attention
ability to focus on relative information and disregard whats irrelevant
younger kids have worse memory for specific information but better with irrelevant memory because of destraction
mnemonics
